Hedera (HBAR) - the full guide

1. TL;DR

Hedera is a public distributed ledger that does not use a blockchain data structure. It runs on hashgraph, a consensus algorithm invented by Leemon Baird and published in May 2016, which orders transactions through "gossip about gossip" and "virtual voting" instead of mining or block production. ^[3][2]

The network is governed by the Hedera Council, a group of large organizations (Google, IBM, Deutsche Telekom, Dell, LG, Standard Bank and others) that each run one consensus node, hold one equal vote and serve up to two consecutive three-year terms. At the time of writing the public mirror node listed 30 consensus nodes, all operated by Council members. ^[6][9][10]

The native token is HBAR. It pays transaction fees that are priced in US dollars (a plain transfer costs 0.0001 USD, paid in HBAR at the live rate) and it can be staked to nodes to weight consensus. Total supply was fixed at 50 billion HBAR when the mainnet went live in August 2018, and changing that number requires the unanimous consent of the Council. ^{[12][18][27][7]}

In 2024 Hedera contributed its entire codebase to the Linux Foundation's LF Decentralized Trust as the open-source project Hiero, licensed Apache 2.0. The Hedera network now runs as one instance of that codebase. ^[35][38][37]

On the regulatory side, a spot HBAR exchange-traded fund has traded on Nasdaq since late October 2025, and a joint SEC and CFTC interpretive release of March 17, 2026 identified HBAR as a "digital commodity" that is not itself a security, while noting that the release is interpretive and not binding law. ^[49][50]

Before holding HBAR, understand four things: Hedera account IDs look like 0.0.12345 rather than a long hex address, sending to a new wallet can silently trigger an account-creation fee, exchanges require a memo on deposits, and HBAR exists only on the Hedera network. ^[14][15][53]

3. What problem does it try to solve

Public blockchains such as Bitcoin and Ethereum proved that strangers can agree on a shared ledger without a central operator. The cost of that proof was speed, energy and uncertainty: blocks arrive every few seconds or minutes, and a transaction is only "probably final" until enough further blocks pile on top of it. Baird's 2016 paper set out to show that a group of computers could reach agreement with mathematical finality, fair ordering and almost no communication overhead beyond the transactions themselves. ^[3]

Think of a classroom where every student is asked to keep an identical diary of events. A blockchain hands the pen to one student at a time, chosen by a lottery, and everyone else copies what that student writes. Hashgraph instead lets every student chat with random classmates, recording not only what they heard but who told them and when. Because everyone eventually learns the full history of who-told-whom, each student can work out, alone and without a vote, the order in which the whole class first learned about each event. ^[3][2]

Hedera's second design decision is about who runs the computers. Rather than letting anyone join as a validator, Hedera started with a permissioned set of nodes run by a council of named enterprises with term limits and equal votes. The pitch is that a business, a bank or a government is more likely to build on a ledger whose operators are identifiable and legally accountable than on one whose operators are anonymous. The trade-off, discussed in chapters 9 and 11, is a far smaller validator set than permissionless networks. ^[6][10]

The third decision is predictability. Fees on Hedera are defined in US dollars and converted to HBAR at the time of each transaction, so an application developer can budget in a currency they understand even if the token price moves. Hedera also offers two services that most chains leave to smart contracts: a Token Service for issuing tokens natively and a Consensus Service that sells nothing but an ordered, timestamped log. ^[13][20][21]

4. History, founders, organization and governance

From Swirlds to Hedera

Leemon Baird developed hashgraph between 2012 and 2015 and, together with his long-time business partner Mance Harmon, formed Swirlds, Inc. to commercialize it. Hedera's own timeline describes both men as US Air Force veterans. The hashgraph technical report was published on May 31, 2016, and the technology was shown publicly at TechCrunch Disrupt in 2017, the same year Swirlds raised the seed round that funded the bootstrapping of Hedera. Secondary sources name Andrew Masanto as a third co-founder. ^[27][3][60]

The Hedera name and HBAR logo were chosen in 2018. A launch event in New York on March 13, 2018 presented the vision of a network "governed by a Council of up to 39 global enterprises." The mainnet went live on August 24, 2018 with 50 billion HBAR minted, but access stayed restricted for another year. Funding came largely from Simple Agreements for Future Tokens (SAFTs): The Block reported a 124 million dollar initial SAFT offering ahead of the public opening. ^[27][29]

In March 2019 Hedera Hashgraph filed a Form D with the SEC covering roughly 696 million dollars of HBAR grants to employees, founders, advisers and early service providers, valued at the 0.12 dollar price of its last financing round. The same report named the first five Council members: Deutsche Telekom, DLA Piper, Magazine Luiza, Nomura Holdings and Swisscom Blockchain. ^[30]

Open Access and the first services

"Open Access" arrived on September 16, 2019. From that day anyone could create a Hedera account and developers could deploy applications. The network was deliberately throttled: cryptocurrency transfers were limited to 10,000 transactions per second while smart contracts and the file service were limited to 10 calls per second. Only about 3.18 percent of all HBAR were expected to be in circulation at that moment, with the rest to be released over a schedule that The Block described as running 15 years. ^[28][29]

The Hedera Token Service launched on mainnet on February 9, 2021, and the Smart Contract Service followed on February 2, 2022. ^[27]

The HBAR Foundation and the Council's treasury decisions

On September 16, 2021 the Council announced that it would direct 10.7 billion HBAR, about 20 percent of total supply and worth about 5 billion dollars at the time, to ecosystem development. Up to 5.35 billion of that was earmarked for a newly created independent HBAR Foundation, led by Shayne Higdon, with autonomy over its own grant decisions. ^[39]

Open-sourcing the algorithm and the move to Swirlds Labs

On January 19, 2022 the Council voted to purchase the intellectual property rights to the hashgraph algorithm from Swirlds, Inc. and committed to publishing it under the Apache 2.0 license during 2022. The code was released as open source on August 5, 2022. ^[31][27][59]

Three months after the vote, on May 1, 2022, Harmon stepped down as CEO of Hedera Hashgraph, LLC and Baird as its Chief Scientist, and both became co-CEOs of a new company, Swirlds Labs, partly owned by Swirlds. The Hedera development and management teams moved with them, and the Council contracted Swirlds Labs to provide the services those teams had previously performed in-house. On July 24, 2024 Swirlds Labs renamed itself Hashgraph. At the time of writing the company described itself as "the development labs team behind Hedera's best-in-class technology" and sold enterprise products such as the HashSphere private network and the Asseto tokenization platform. ^[32][33][34]

Hiero: the code goes to the Linux Foundation

On September 16, 2024 Hedera announced that its core software - the consensus node, mirror node, JSON-RPC relay, SDKs in Java, JavaScript, Go, C++, Rust and Swift, and the explorer - would be contributed to LF Decentralized Trust under the name Hiero, with vendor-neutral governance and an Apache 2.0 license. Hedera also became a founding Premier Member of LF Decentralized Trust. By February 2025 Hedera stated that "the Hedera public ledger now operates as an instance of the Hiero codebase," overseen by a nine-member Technical Steering Committee, and at the time of writing the LF Decentralized Trust site listed Hiero as a graduated project. ^{[35][36][38][37]}

How the Council works

Membership is governed by the Hedera Council LLC Agreement, which members sign on admission. Members have an equal vote on the direction of Hedera's software and services, serve up to two consecutive three-year terms, run the network's consensus nodes and approve technology updates. Committees are elected annually, and decisions are recorded in public meeting minutes. The Council's "About" page counted 33 organizations from 13 industries at the time of writing; Hedera's HBAR page counted 31 Council members. ^[6][5][1]

In 2025 Hedera's timeline records a rebrand "from Governing Council and HBAR Foundation to Hedera Foundation." The Hedera Foundation site describes its mission as driving "adoption of the world's leading public network" and names Charles Adkins, formerly President of Hedera, as CEO. The Council itself continues to publish membership and treasury information on its own site. ^[27][40][6]

5. The technology, explained simply

Gossip about gossip

In hashgraph, each node repeatedly picks another node at random and tells it everything it knows. Each such exchange is recorded as an "event" that contains the new transactions plus two hashes pointing to the last event of each participant. The chain of these events forms a graph - the hashgraph - that is a complete, tamper-evident record of who learned what from whom and when. Baird's paper summarizes the idea in one sentence: participants "don't just gossip about transactions. They gossip about gossip." ^[3]

Virtual voting

Classic Byzantine agreement protocols spend most of their bandwidth on votes. Hashgraph sends none. Because every node eventually holds the same hashgraph, each node can compute how every other node would have voted, so the votes happen "virtually" inside each machine. The official documentation puts it this way: virtual voting "allows nodes to know what others would vote for without needing actual votes sent over the internet." The result is a consensus timestamp for each transaction equal to the median of the times at which members first received it, which makes it hard for one node or a few faulty clocks to shift the order. ^[2][3]

Asynchronous Byzantine fault tolerance

Hashgraph is described as asynchronous Byzantine Fault Tolerant (aBFT): as long as more than two thirds of the nodes follow the protocol, no small group can prevent consensus or reverse it once reached, with no assumption about how fast messages travel. In October 2018 Karl Crary, an associate professor of computer science at Carnegie Mellon University, completed a machine-checked proof of this property in the Coq proof assistant. This is a proof of the algorithm, not of any particular software implementation. ^[2][4]

Speed, fees and finality

Hedera's marketing page reports that transactions are "finalized in under 3 seconds and can't be reversed," lists a consensus finality figure of 2.90 seconds, and claims 10,000 or more transactions per second. The documentation shows the same 10,000 figure as the network throttle for transfers, with much lower limits for other operations such as 2 account creations per second and 5 topic creations per second. These are network-imposed caps, not measured peak load; chapter 7 looks at what the network actually carries. ^[1][11]

Fees are defined in US dollars, stored as "tinycents" in a system file, and converted to HBAR at the network exchange rate at the moment of each transaction. Every fee has three parts: a node fee for the submitting node, a network fee (by default nine times the node fee) for gossip, consensus and storage, and a service fee for execution. At the time of writing the published schedule listed 0.0001 USD for a plain HBAR transfer, 0.001 USD for a token transfer, 0.0008 USD for a Consensus Service message and 0.05 USD for creating an account. The docs warn that all fees are subject to change. ^[13][12]

Proof-of-stake weighting

Hedera describes itself as a proof-of-stake network: a transaction is final once nodes representing more than two thirds of all staked HBAR have processed it, and "each node's influence on consensus is proportional to the amount of cryptocurrency it has staked." Any account can stake its balance to a node by updating one account field. The stake stays liquid, there is no lock-up, and rewards are paid at a rate capped by the Council through its Coin Committee. Rewards that are not triggered within 365 days can only be collected for the last 365 days. The documentation we reviewed describes no slashing penalty. ^[18][19]

The three services

Hedera Token Service (HTS). Tokens, fungible and non-fungible, are a native object of the ledger rather than a smart contract. An issuer can attach keys that control supply, freeze specific accounts, enforce KYC, wipe balances or pause the token entirely, and can define custom fees such as royalties that the network collects automatically. An account must "associate" with a token before it can hold it. ^[20]

Hedera Consensus Service (HCS). HCS sells only ordering. An application creates a "topic," submits messages to it, and the network returns each message with a consensus timestamp and a sequence number; Hedera compares it to "a decentralized notary, providing verifiable and immutable timestamps for events without storing the data itself." Topics can be restricted with a submit key and can charge a per-message fee in HBAR or an HTS token. Hedera names supply chain, stablecoin issuance, digital identity and DAO voting records among the use cases. ^[21][22]

Smart Contract Service. Hedera runs an Ethereum Virtual Machine (the Hiero consensus node uses Hyperledger Besu for EVM support), so Solidity contracts can be deployed with Hardhat, Foundry or Remix. There are differences: Hedera accounts may use ED25519 keys that Ethereum tooling does not understand, HTS tokens are reached through system contracts, and the JSON-RPC relay does not behave exactly like an Ethereum node. Each transaction is capped at 15 million gas. ^[35][23][24]

Consensus nodes versus mirror nodes

Only Council members run consensus nodes. Mirror nodes are different: anyone can run one, they receive signed records from the consensus nodes, store the full history and serve queries, but "they do not contribute to consensus themselves." The public HashScan explorer and the public mirror node REST API used in this guide are examples. ^[10][25][57]

6. The token

Supply

Total supply is 50,000,000,000 HBAR, minted at mainnet launch in August 2018. The Council's treasury page states that the total "may not be modified without the unanimous consent of the members of the Hedera Council." One HBAR divides into 100 million tinybars, the atomic unit used by the network. ^[7][27][26]

Hedera does not use the term circulating supply; it reports "Released Supply," meaning HBAR transferred out of treasury into user accounts. At the time of writing the public mirror node API returned a released supply of about 44.0 billion HBAR, or 88 percent of total. The Council's treasury report, dated October 6, 2026, showed a higher figure of about 47.84 billion HBAR (95.69 percent) in its most recent column, labelled as a Q4 2026 forecast. The two figures use different definitions, and the mirror node number is the one anyone can reproduce. ^[7][8]

Allocation and release schedule

The treasury report breaks the 50 billion into four buckets as of its 2025 table: 7.77 percent for initial development costs and licensing, 25.40 percent for purchase agreements (the SAFT and later sales), 16.23 percent for network governance and operations (including 780 million HBAR reserved for the board but not yet distributed), and 50.61 percent for ecosystem and open-source development. Unallocated supply is zero. Releases are reported quarterly in thousands of HBAR, with a forecast for the following quarter, and "Illiquid Supply" has been zero since Q3 2024. ^[7]

Source: ^[7]

What HBAR is for

HBAR has three protocol-level jobs. It pays every fee on the network, converted from the USD-denominated schedule at the live rate. It is the staking weight that determines each node's influence on consensus and earns staking rewards. And it is the unit that auto-creates accounts and pays for token associations, so it is needed to use any HTS token at all. ^[12][18][15]

Distribution and concentration

The 2021 decision to route 10.7 billion HBAR, about a fifth of all supply, through the HBAR Foundation and other ecosystem programs means that a large share of the coins that have reached the market came as grants rather than sales. Early insiders received about 696 million dollars of HBAR grants at a 0.12 dollar valuation, typically vesting over four years. Both facts are disclosed, and the quarterly treasury report is unusually detailed for a public network, but a reader should not confuse "fixed supply" with "widely distributed supply." ^[39][30][7]

7. Real adoption

We separate three kinds of evidence: production usage that can be checked on-chain or in company filings, announcements and pilots, and narratives we could not verify.

8. The ISO 20022 connection

ISO 20022 is a messaging standard for financial institutions: a shared dictionary and format for payment instructions, securities messages and the like, used by banks, market infrastructures and the SWIFT network. It is a standard for messages between institutions, not a certification that any cryptocurrency can earn. Our explainer at /learn/iso-20022 covers the standard itself.

Hedera appears regularly on social media lists of "ISO 20022 coins." We checked Hedera's HBAR page, its documentation on fees, accounts and services, the Council's governance and treasury pages, and the SEC filings of the two HBAR funds, and found no claim by Hedera, the Council or Hashgraph that HBAR or the network is "ISO 20022 compliant." ^{[1][12][6][49]}

What is true is narrower. Hedera's Council includes payment and banking organizations such as Australian Payments Plus, Shinhan Bank, Standard Bank and Nomura, and the Consensus Service is pitched at use cases such as stablecoin issuance and FX trading. A bank could, in principle, record ISO 20022 message hashes on HCS or move an HTS-issued asset while exchanging ISO 20022 messages off-chain. None of that makes the token itself "compliant" with a messaging standard. ^[9][21]

9. Ecosystem and competitors

Inside the ecosystem

The Hedera ecosystem is organized around several entities. The Hedera Council governs the network and treasury. Hashgraph (formerly Swirlds Labs) employs most of the core engineers and sells enterprise products. The Hedera Foundation, successor to the HBAR Foundation, funds "DeFi and enterprise projects that drive Hedera network adoption." The code lives in the Hiero project under LF Decentralized Trust. ^{[6][34][40][37]}

For users, the most visible tools are HashPack, a non-custodial Hedera wallet that supports native staking and Ledger hardware wallets; HashScan, the public block explorer; and SaucerSwap, a decentralized exchange whose documentation lists Binance, Coinbase, KuCoin and MEXC among exchanges that list HBAR. Hedera's staking documentation names HashPack, Kabila, BankSocial, Atomic and Uphold as wallets that support staking. ^{[56][57][55][19]}

Competitors

Hedera competes on three fronts. Against general-purpose layer-1 smart-contract platforms such as Ethereum and Solana it offers aBFT finality, USD-fixed fees and native tokens, but a far smaller developer and liquidity base. Against payment-focused ledgers such as XRP, Stellar and Algorand it offers a similar fee and speed profile with a different governance story: a council of enterprises rather than a foundation or a validator list. And against private, permissioned ledgers such as Hyperledger Fabric, which enterprises have used for internal consortia, Hedera argues that a public ledger with accountable operators gives the same comfort with more openness; Hashgraph's own HashSphere product shows the company also sells the private option. ^[1][6][34]

The honest summary is that Hedera's clearest differentiators are its consensus algorithm, its governance model and the Consensus Service, while its clearest weaknesses are a small permissioned validator set and a DeFi ecosystem whose total locked value was measured in tens of millions of dollars at the time of the 2023 exploit. ^[2][10][47]

10. Regulation and legal history

United States

Hedera has been careful with US securities law from the start. Its 2019 Form D stated that "the coins released under these grants should not be viewed as securities at the time they are delivered," while acknowledging that "it remains possible that hbars will be deemed to be securities even at the time of delivery," and it structured the grants to fit an exemption in case they were. ^[30]

HBAR was never named in an SEC enforcement action, and in 2025 the token reached US regulated markets through an exchange-traded fund. Canary Capital's spot HBAR ETF prospectus is dated October 27, 2025, and the fund trades on Nasdaq under HBR. Its May 2026 amendment records that on March 17, 2026 "the SEC and the CFTC jointly issued an interpretive release that specifically identified HBAR as a 'digital commodity'" that "is not itself a security because it does not have the economic characteristics of a security," within a five-category digital asset taxonomy. The same filing stresses that "it is an interpretive rule and not binding law" and that there is no assurance the agencies will not modify or withdraw it. The release itself confirms that HBAR is in its main list of sixteen examples, alongside XRP, XLM and ADA. ^[49][50][61]

Grayscale's September 2025 S-1 for a competing fund noted that, as of that date, "the SEC... have not made official pronouncements" on HBAR specifically; the March 2026 release post-dates that filing. ^[51]

European Union

The EU's Markets in Crypto-Assets Regulation (MiCA) "institutes uniform EU market rules for crypto-assets," entered into force in June 2023, applied fully from December 2024, and allows member states a transitional period for existing service providers until 1 July 2026. MiCA mainly regulates issuers of stablecoins and crypto-asset service providers such as exchanges; HBAR, as a token with no issuer offering it to the public today, is affected mostly through the exchanges that list it. ESMA's interim register lists a MiCA white paper for HBAR drawn up by Payward Global Solutions, which operates Kraken's EU trading platform, and notified to the Central Bank of Ireland (record dated 2025-07-14); it names Hedera Hashgraph, LLC as the issuer. A second one comes from the Liechtenstein exchange LCX. These are disclosure documents, not approvals. ^[52][62]

Exchange availability

HBAR is listed on Kraken, which publishes a dedicated deposit-memo help page, and on Binance.US, whose help center lists HBAR among memo-required assets. Coinbase Custody Trust Company was named as a custodian in the Canary ETF's 2025 prospectus. See the exchange and wallet matrix in chapter 14 for the verified list used on this site. ^[53][54][49]

Litigation and incidents

We found no securities litigation against Hedera Hashgraph LLC, the Council or Hashgraph concerning HBAR. The main legal-adjacent event in Hedera's history is technical: the March 2023 Smart Contract Service exploit described in chapter 11. ^[45][47]

11. Key risks

1. Permissioned validation and the ability to switch the network off. All 30 consensus nodes are run by Council members, and the Council approves upgrades. On March 9, 2023, after "network irregularities," Hedera itself turned off the mainnet network proxies, "making it inaccessible," until a patch could be deployed. Supporters saw a responsible emergency response; critics saw a network that a small group can halt. Both readings are correct, and a reader should decide which matters more to them. ^[10][46][47]

2. Smart-contract security record. The 2023 incident was an exploit of the Smart Contract Service code that let attackers "transfer Hedera Token Service tokens held by victims' accounts," draining liquidity pools on SaucerSwap, Pangolin and HeliSwap; the stolen amount was never disclosed, and PeckShield measured a 33 percent drop in total value locked. The algorithm's aBFT proof covers consensus, not application-layer code. ^[45][47][4]

3. Dependence on a few organizations. Core development is concentrated at one company, Hashgraph, under contract to the Council. Hiero's Linux Foundation governance reduces the risk that any one company can capture the code, but the people who write most of it still sit in one place. ^[32][34][38]

4. Treasury overhang. Roughly 12 percent of supply by the mirror node's count, or about 4 percent by the Council's own definition, had not reached user accounts at the time of writing, and more than half of all HBAR was allocated to ecosystem grants. Release timing is decided by the Council and published quarterly, not fixed in code. ^[8][7]

5. Roadmap promises still open. The 2018 launch described a path toward broader node participation; at the time of writing the roadmap listed a "Dynamic Address Book" and node-reward mechanisms as the current decentralization work, without dates for permissionless nodes. Score roadmaps as roadmaps. ^[27][58]

6. Regulatory reversal. The March 2026 interpretive release is helpful but, in the words of the ETF filing, "not binding law," and the agencies may "modify, supersede, or withdraw" it. ^[50]

7. Operational pitfalls for holders. Account IDs, aliases, hollow accounts, memos and association fees are different from any other major network, and mistakes with them are the most common way retail users lose HBAR. Chapter 14 explains each. ^[14][15][53]

8. Fee predictability depends on the exchange rate feed. Fees are fixed in USD but paid in HBAR at a network exchange rate; the docs warn that "all fees are subject to change" and that estimates "may not be 100% accurate." ^[12]

This chapter is educational and is not investment advice.

12. Bull case vs bear case

The bull case

Supporters point to a consensus algorithm with an unusually strong formal record: a published 2016 paper and a 2018 machine-checked Coq proof that it is asynchronous Byzantine fault tolerant. Fees are set in US dollars, with a plain transfer at 0.0001 dollars, and the 30 consensus nodes are run by named global companies such as Google, IBM, Dell and Deutsche Telekom that carry legal accountability. Activity is measurable at network level (more than 71 billion transactions in total and about 799,000 in 24 hours at the time of writing), and Avery Dennison's atma.io and the open-source Guardian are verifiable deployments. The code now sits under the Linux Foundation as Hiero, answering the long-standing objection that it was proprietary, and the March 2026 SEC and CFTC interpretive release plus a Nasdaq-listed spot ETF give HBAR a clearer legal footing than most tokens. ^{[3][4][12][9][10][1][41][42][44][35][50]}

The bear case

Skeptics reply that seven years after Open Access the network is still permissioned: 30 nodes, all run by Council members, and no dated plan for permissionless validation. Most Council members are node operators rather than visible production users, and there is no independent split between low-value Consensus Service logging and value transfer, so the headline transaction count says little about economic use. The DeFi ecosystem is small, and a 2023 exploit drained liquidity pools, cut total value locked by about a third and led Hedera to switch off network access. A fixed 50 billion cap has not meant a fixed float: about 44 billion HBAR had been released by verification, and more than half of the supply was allocated to ecosystem programs whose release timing the Council decides. ^{[10][58][6][1][45][47][46][8][7][39]}

Both cases rest on verifiable facts; they differ on whether accountable, enterprise-run governance is a strength for regulated users or a ceiling on decentralization and organic demand. The reader decides.

What both sides can monitor

Several things can be checked over time. One is the roadmap for permissionless nodes and whether it gains dates. Another is the quarterly treasury report and the gap between released and total supply. A third is any independent breakdown of transaction types from public mirror node data. A fourth is whether the 2026 interpretive release is kept, revised or withdrawn. ^{[58][7][8][1][50]}

Scores follow the rubric used for every coin on this site; the rationale for each category is shown in the card.

14. How to buy and store

Before the exchange and wallet list, four Hedera-specific pitfalls that cause most lost funds.

1. Account IDs versus EVM addresses. A Hedera account is identified by a number in the form shard.realm.number, so every mainnet account looks like 0.0.1234. Account numbers are assigned by the network and never change. Since HIP-583, an account can also carry an alias in the form of a 20-byte hex EVM address derived from an ECDSA public key, and the mirror node can display a "long-zero" hex form of any account number. These are three different representations, and a wallet or exchange may accept only some of them. Always paste exactly the format the receiving service asks for, and verify it on HashScan before sending. ^[14][17][57]

2. Auto account creation costs money. If you send HBAR to an alias (a public key or an EVM address) that has no account yet, the network silently creates one and charges the account creation fee (0.05 USD in HBAR at the time of writing) as part of the transfer. Under HIP-32 the fee is deducted from the amount sent, so the recipient receives less than you typed; under the current docs the payer covers both the transfer fee and the creation fee. If the amount is too small to cover the fee, "the transaction fails, and nothing is created." An account created from an EVM address is a "hollow account" that can receive but cannot send until its owner signs a transaction with the matching key. Send a small test transaction first and check the new account ID on HashScan. ^{[15][16][17][12]}

3. The memo when sending to an exchange. Exchanges hold all customer HBAR in one account and identify you by the memo on your transaction. Kraken states that a "unique and mandatory Memo" is created with your deposit address, a 19-digit numeric code, and that "you must include this Memo with every HBAR deposit you send to Kraken"; a missing or mistyped memo can significantly delay crediting and "the deposit may be irretrievable." Binance.US lists HBAR among assets that require a memo. Copy both the account ID and the memo from the exchange's deposit page every time. ^[53][54]

4. Send HBAR only on the Hedera network. HBAR is a native asset of the Hedera ledger. Some exchanges and bridges offer wrapped versions on other chains; if a withdrawal screen asks you to choose a network, choose Hedera, and never send HBAR to an Ethereum, BNB Chain or Solana address even though a Hedera EVM alias looks identical to an Ethereum address. The same applies to HTS tokens: an HTS token can only be received by a Hedera account that has associated with it (accounts created by auto creation associate automatically). Network selection errors are usually irreversible. ^{[23][20][15][55]}

Two more habits: when staking, remember that your balance stays liquid and in your own wallet, so any service asking you to "send HBAR to stake" is not using native staking; and if you hold HBAR on an exchange, remember that you then depend on the exchange's custody, not on Hedera's consensus. ^[18][19]
