The difference between coins and tokens comes down to where an asset lives. A coin is the native asset of its own blockchain and pays that chain’s fees: BTC on Bitcoin, ETH on Ethereum, SOL on Solana. A token is a balance recorded by a smart contract running on somebody else’s blockchain. USDT on Ethereum is a token, and you need ETH to move it. Most coin vs token questions come down to that example.
It sounds like jargon until it costs you money. People send USDT on the wrong network, or find a token balance they cannot move because the wallet holds no coin to pay the fee. This lesson follows our introduction to what cryptocurrency is. It covers the vocabulary, a two-minute check you can run on any asset, and how US and UK regulators and tax offices treat the split. Figures are as of October 2026.
Coin vs token: the short answer
A coin is written into a blockchain’s protocol. The software every node runs knows what bitcoin is, how the supply grows and which address owns which amount. Nobody deployed a program to create it. Developers call this a native asset.
Tokens come later, and they are made by code. Someone writes a smart contract, publishes it on a host chain such as Ethereum, Solana or Tron, and that contract keeps its own ledger of who holds how many units. The host chain has no idea what the token represents. It runs the contract and charges a fee, in its own coin, each time the contract does something.
So the practical test is a single question: what pays the fee? An asset that pays for its own transactions is a coin. One that needs another asset to move is a token on that chain.
Everyday usage is looser. CoinGecko calls every asset it lists a “coin”, and its categories page counted more than 22,000 of them on 14 October 2026, tokens included. Most “memecoins” are tokens too: SHIB, PEPE and WIF live in contracts on other chains, while DOGE runs on its own blockchain. In this guide, “coin” means native coin and nothing else.
What makes a coin native to its blockchain
The protocol creates it
Native coins come out of the chain’s own rules. Bitcoin pays newly issued coins plus fees to the miners who add blocks. Ethereum pays the validators who stake ETH. Issuance, rewards and the way balances are recorded all sit in the client software, so changing them means changing the protocol, and that needs broad agreement among the people who run nodes.
That is also why a coin has no contract address. Search for BTC or ETH on a block explorer and you find balances and transactions, but no contract that issues them.
It pays the network fees
Every public chain charges for the block space and computing a transaction uses, and it charges in its own coin. The mechanics vary from chain to chain:
| Chain | Fee paid in | How the fee works |
|---|---|---|
| Bitcoin | BTC | Whatever the inputs hold beyond the outputs goes to the miner. The fee depends on the transaction’s size in bytes, not on the amount sent (Bitcoin developer guide) |
| Ethereum | ETH | Gas is priced in gwei, one billionth of an ETH. The base fee is burned and an optional tip goes to the validator. A plain ETH transfer uses 21,000 gas |
| Solana | SOL | 5,000 lamports per signature, half burned and half paid to the validator, plus an optional priority fee |
| BNB Smart Chain | BNB | Fees are paid in BNB and go to the block producers |
| Tron | TRX | Bandwidth (600 free units per rolling 24 hours) plus Energy for contract calls, which has no free quota. Missing Energy is paid by burning TRX |
| TON | TON | A token transfer is a message that the sender’s wallet pays for in TON |
“Gas fees have to be paid in Ethereum’s native currency, ether (ETH),” says the ethereum.org documentation on gas. Our glossary entry on gas fees explains why those prices rise and fall with demand.
One exception confuses people. Some wallets let you pay a fee “with” a token. MetaMask offers this on Ethereum, BNB Smart Chain, Arbitrum, Base, Polygon and Linea, and its help page says that on other networks you need enough of the native token. Behind the scenes a relayer pays the chain in its coin and charges you in the token. The chain itself still accepts nothing but its native asset.
A token is a balance inside a smart contract
Strip away the logo and a token is a table: addresses in one column, numbers in the other. The contract that owns the table has functions to read a balance and to move units between rows. When your wallet shows 500 USDT on Ethereum, it is reading a number stored in the contract at 0xdac17f958d2ee523a2206206994597c13d831ec7, the address Tether publishes for its Ethereum token.
Because the contract is ordinary code, its author decides what it can do. Minting new units, burning them, freezing an address, taking a cut of each transfer, pausing trading: each one is a design choice. That flexibility is why there are millions of tokens, and why a token can carry risks that a coin does not.
ERC-20, the standard that made tokens easy
Early Ethereum tokens each had their own interface, so wallets and exchanges wrote custom code for every one. EIP-20, created on 19 November 2015 by Fabian Vogelsteller and Vitalik Buterin, fixed that. Its summary reads, in full: “A standard interface for tokens.”
It requires six functions (totalSupply, balanceOf, transfer, transferFrom, approve and allowance) and two events, Transfer and Approval. Name, symbol and decimals are optional. A contract built to this shape works in any wallet that reads ERC-20, so a new token can appear in wallets minutes after launch.
Approve and allowance matter for your safety. With approve, you let another contract, such as a decentralized exchange or a lending app, spend your tokens up to a limit. Allowance stores that permission, and it stays in place until you change it. The mistakes at the end of this guide come back to it.
BEP-20, TRC-20, SPL and Jettons: the same idea on other chains
Each large smart-contract chain has its own version of the standard.
- BEP-20 on BNB Smart Chain was derived from ERC-20 and makes the symbol and decimals mandatory.
- TRC-20 on Tron matches ERC-20 at the interface level, and Tron’s documentation says Solidity code written for ERC-20 runs with small modifications. USDT on Tron is a TRC-20 token.
- SPL tokens on Solana share one program instead of one contract per token. Each token type is a “mint” with a mint authority, and balances sit in separate token accounts. Once the mint authority is removed, the Solana docs say, “No further tokens can ever be Minted.”
- Jettons on TON follow the TEP-74 standard, which the TON documentation presents as the counterpart of Ethereum’s ERC-20. A jetton master contract stores the metadata and total supply, and each holder gets a separate jetton wallet contract.
Solana’s newer program, Token-2022 (also called Token Extensions), adds options such as transfer fees, confidential transfers, pausing and a permanent delegate. That last one gives a chosen address the power to transfer or burn tokens from any holder’s account, and the holder cannot switch it off. It can make sense for a regulated asset. For anyone who assumed a token behaves like cash in a pocket, it is a surprise, so look at a Solana token’s extensions on an explorer before you hold it.
NFTs are tokens too
Everything above is fungible: one USDT is worth exactly what any other USDT is worth. ERC-721, created on 24 January 2018, brought non-fungible tokens to Ethereum; its summary calls them “also known as deeds”. Each unit has its own ID, so token 17 cannot stand in for token 18.
ERC-1155 followed on 17 June 2018. One contract can hold fungible and non-fungible token types side by side, which suits games that need a currency and unique items at the same time.
Coins vs tokens compared side by side
| Coin (native asset) | Token | |
|---|---|---|
| Where it lives | In its own blockchain’s protocol | In a smart contract or token program on a host chain |
| Examples | BTC, ETH, SOL, BNB, TRX, TON | USDT, USDC, UNI, LINK, SHIB, WBTC, NFTs |
| Pays network fees | Yes, on its own chain | No: the host chain’s coin pays (some wallets relay the fee for you) |
| Created by | Protocol rules: mining or staking rewards, genesis supply | The contract’s mint function, controlled by an issuer or by code |
| Standard | None needed, the protocol defines it | ERC-20, ERC-721, ERC-1155, BEP-20, SPL or Token-2022, TRC-20, Jetton |
| How to identify it | Chain name and ticker | Contract address (or mint) on a given chain |
| On several chains | Only as wrapped or bridged copies (WBTC, WETH) | Often: Tether lists USDT on 13 networks (October 2026) |
| Main extra risk | The risk of its own chain | Host chain risk plus contract and issuer risk: freezes, new mints, bugs, fake copies |
Is bitcoin a coin or a token? Quick answers for popular assets
The fee test answers each “is X a coin or a token” question in one line.
| Asset | Coin or token | Why |
|---|---|---|
| Bitcoin (BTC) | Coin | Native asset of the Bitcoin blockchain; pays its fees |
| Ether (ETH) | Coin | Native to Ethereum; pays gas |
| Solana (SOL) | Coin | Native to Solana; pays transaction fees |
| BNB | Coin | Native to BNB Smart Chain; pays fees there |
| XRP | Coin | Native to the XRP Ledger, where each transaction destroys a small amount of XRP as its cost |
| Dogecoin (DOGE) | Coin | Native to the Dogecoin blockchain |
| TRX | Coin | Native to Tron; burned for Energy and Bandwidth |
| Toncoin (TON) | Coin | Native to The Open Network |
| Tether (USDT) | Token | Issued on 13 host networks, each with its own address |
| USD Coin (USDC) | Token | Stablecoin issued through contracts on host chains such as Ethereum |
| Uniswap (UNI) | Token | ERC-20 governance token on Ethereum |
| Chainlink (LINK) | Token | ERC-20 token on Ethereum; Chainlink does not run a chain with its own gas coin |
| Shiba Inu (SHIB) | Token | ERC-20 memecoin on Ethereum |
Ether causes the most confusion. ETH is a coin in the strict sense: validators are paid in it and gas is paid with it. But ETH predates ERC-20, so apps built only for ERC-20 use a wrapped version called WETH. Our guide to Ethereum covers how the network and its smart contracts work.
One token, many chains: the USDT example
As of 14 October 2026, Tether’s supported-protocols page lists USDT on 13 networks: Ethereum, Avalanche, Cosmos via Kava, Celo, Kaia, Tron, Liquid, Solana, Polkadot Asset Hub, Tezos, Near, TON and Aptos.
Same name, same ticker, same dollar peg, yet each version is a separate token with its own identifier. On Ethereum it is the ERC-20 contract starting 0xdac17f. On Tron it is the TRC-20 contract TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t. On Solana it is the SPL mint Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Moving each one takes a different coin: ETH, TRX or SOL.
The chains cannot see one another. A Tron wallet rejects an Ethereum address outright, since Tron addresses start with T and Ethereum ones with 0x. The real trap sits between chains that share the 0x format, covered with the mistakes below.
Tether has also stopped issuing on some older networks. Its page lists Kusama, Bitcoin Cash SLP, Omni Layer, EOS and Algorand as discontinued, with Tether “no longer issuing or obligated to redeem” its tokens there. USDT on BNB Chain, Arbitrum, Polygon or Base is not on Tether’s list of supported protocols at all: those versions are bridged or pegged copies run by third parties, not tokens Tether issues there itself. Our guide to stablecoins explains how the dollar backing works.
Wrapped tokens: WETH and WBTC
Wrapping turns an asset into a token on a chain where it would not otherwise fit. WETH is the simple case. ETH predates ERC-20, so it does not follow that interface. You deposit ETH into the WETH contract and receive the same amount of WETH; unwrapping burns the WETH and returns the ETH. Both steps cost gas in plain ETH, because, as ethereum.org notes, paying gas with WETH is not natively supported.
WBTC is a different animal, because bitcoin cannot run on Ethereum. A custodian holds real BTC and a contract mints the same amount of WBTC. The WBTC site says each token is “backed 1:1 by Bitcoin in secure custody”, and only identity-verified institutions approved through its DAO governance can mint or burn it.
The custodian is the part to watch. On 9 August 2024, BitGo announced it would move WBTC custody into a joint venture with BiT Global, a Hong Kong custody firm, with BitGo as a minority shareholder and keys spread across jurisdictions including Hong Kong and Singapore. Within days, MakerDAO governance stopped new loans backed by WBTC, according to The Block. The token’s code had not changed. Who held the bitcoin had.
Bridged tokens add another layer of risk
A bridge locks a token on one chain and issues a matching one on another. If the bridge’s contracts or keys are compromised, the copies can lose their backing at once. Ethereum.org’s page on bridges says that “Interacting with any type of bridge carries risk” and gives Solana’s Wormhole bridge as an example: about 120,000 wETH, worth around $325 million, was stolen in that hack in February 2022.
Wormhole was one of many. Chainalysis counted about $2 billion stolen in 13 cross-chain bridge hacks in 2022 up to early August, and wrote that “Attacks on bridges account for 69% of total funds stolen in 2022 so far.”
How to check if a crypto is a coin or a token
You do not need to read code. A block explorer and two minutes will do.
- Open the explorer for the chain you use: Etherscan for Ethereum, BscScan for BNB Smart Chain, Solscan for Solana, Tronscan for Tron, Tonviewer for TON.
- Search for the asset and look for a contract address (a mint address on Solana, a jetton master on TON). If there is one, the asset is a token on that chain. Native coins have none.
- Check what pays the fee. If your wallet needs ETH, BNB, SOL, TRX or TON to move the asset, you hold a token.
- Compare the contract address with the one on the issuer’s official page, character by character. Tether, for instance, publishes every USDT address on its supported-protocols page. The ticker proves nothing.
- Read the explorer’s token page: number of holders, reputation labels, and whether the source code is verified.
Step four is where people lose money. Anyone can deploy a contract named “Tether USD” with the symbol USDT in a few minutes. Etherscan’s token tracker counted more than 2.3 million token contracts on Ethereum on 14 October 2026, and only 3,584 of them carried an OK or Neutral reputation flag.
If a genuine token does not show up in your wallet, add it by its contract address, copied from the issuer’s site rather than from a search ad or a chat message. Our guide to crypto wallets shows where that option sits in common wallets and why you should keep some of the native coin next to your tokens.
Types of crypto tokens: stablecoins, governance, utility and more
Coin versus token is a technical line. People also sort tokens by what they are used for, and those labels overlap: one token can be a stablecoin and a payment tool at once.
Stablecoins
Tokens that track a currency, mostly the US dollar. Stablecoins were worth about $293 billion in total on 14 October 2026, according to rwa.xyz, and CoinGecko’s stablecoin category listed 404 of them. USDT and USDC are the biggest.
Governance tokens
These give holders a vote on how a protocol changes. Uniswap launched UNI on 16 September 2020 with 1 billion tokens minted at genesis and 60% set aside for the community; every address that had used Uniswap v1 or v2 before 1 September 2020 could claim 400 UNI. AAVE plays a similar role for the Aave lending protocol. CoinGecko’s governance category had 259 entries in October 2026.
Where a vote ends and a claim on revenue begins is one of the questions securities regulators ask about such tokens.
Utility tokens
Tokens that give access to a product or service, such as storage, computing power or features inside an app. The EU’s MiCA regulation defines a utility token narrowly, as a crypto-asset “only intended to provide access to a good or a service supplied by its issuer”.
Tokenized real-world assets
Treasury funds, bonds and other traditional assets recorded as tokens. Rwa.xyz put distributed tokenized real-world assets at about $39 billion on 14 October 2026. The largest tokenized Treasury funds it listed, USYC, USDY and BlackRock’s BUIDL, were each worth more than $2 billion. A fund share on a blockchain is still a fund share: the SEC’s 2026 taxonomy, below, keeps tokenized securities inside securities law.
Meme coin vs token: most memecoins are tokens
Memecoins are “inspired by internet memes, characters, current events, or trends”, in the words of the SEC’s Division of Corporation Finance, and usually have little or no use. In a staff statement of 27 February 2025 it added that “the value of meme coins is derived from speculative trading and the collective sentiment of the market, like a collectible.” The staff view is that trading such memecoins is not a securities transaction, so buyers do not get the protection of federal securities laws.
CoinGecko’s meme category counted about 6,500 entries in October 2026. Nearly all are tokens. Dogecoin is the famous coin among them.
Why the word token carries legal baggage
In 2017 a wave of projects raised money by selling tokens straight to the public, in what became known as initial coin offerings. The name said “coin”. The product was almost always an ERC-20 token, and regulators had to decide whether buyers had bought securities.
The SEC gave its first answer on 25 July 2017, in a report on The DAO. That Ethereum project had sold about 1.15 billion DAO Tokens for about 12 million ETH, worth roughly $150 million at the time, before an attacker used a flaw in its code to take about a third of the ether. The Commission found that DAO Tokens were securities under the Securities Act of 1933 and the Securities Exchange Act of 1934, and decided not to bring an enforcement action.
From then on, anyone launching a token in the US had to reckon with the Howey test, named after a 1946 Supreme Court case: did buyers invest money in a common enterprise, expecting profits from the efforts of others?
Regulators sort crypto by function, not by coin or token
The technical rule you have just learned barely exists in law. A native coin and a token can share a legal category, and two ERC-20 tokens can end up in different ones.
SEC and CFTC: the March 2026 crypto asset taxonomy
SEC Chairman Paul Atkins announced Project Crypto on 31 July 2025. Speaking at the Federal Reserve Bank of Philadelphia on 12 November 2025, he previewed a set of categories and argued that “Investment contracts can be performed and they can expire.” On 17 March 2026 the SEC issued an interpretation, Release No. 33-11412, on how the securities laws apply to certain crypto-assets. The CFTC joined it, saying it will administer the Commodity Exchange Act in line with it.
The SEC’s fact sheet on the release sorts crypto-assets into five groups:
- Digital commodities, not securities: their value comes from the programmatic operation of a “functional” crypto system and from supply and demand.
- Digital collectibles, not securities: art, music, trading cards, in-game items and references to internet memes.
- Digital tools, not securities: memberships, tickets, credentials, title instruments and identity badges.
- Payment stablecoins under the GENIUS Act, signed into law on 18 July 2025: not securities.
- Digital securities, also called tokenized securities: still securities.
According to a review of the release by the law firm Venable, the digital commodities it names include Bitcoin, Ether, Solana and XRP, but also Chainlink and Shiba Inu, which are ERC-20 tokens. In the US view of 2026, LINK is technically a token and legally a digital commodity, in the same group as BTC. The fact sheet adds that protocol mining, protocol staking and wrapping a non-security crypto-asset do not involve the offer or sale of a security.
This is an interpretation, not a statute. It took effect when it was published in the Federal Register on 23 March 2026, according to Gibson Dunn, the SEC asked for public comment, and the Commission says it may refine or revise it. An asset that is not a security can also still be sold as part of an investment contract, so the way a token is marketed keeps mattering.
MiCA: e-money tokens, asset-referenced tokens and other crypto-assets
MiCA, the EU regulation on pool di un market maker automatico divergono, rispetto a tenere semplicemente gli stessi token. Diventa definitiva al prelievo.">Il MiCA (Markets in Crypto-Assets) è il regolamento europeo 2023/1114 che fissa regole comuni per gli emittenti di cripto-attività, le stablecoin e i prestatori di servizi per le cripto-attività (CASP) in tutta l’UE. Si applica pienamente dal 30 dicembre 2024.">markets in crypto-assets (Regulation (EU) 2023/1114), entered into force in June 2023. Its rules on asset-referenced and e-money tokens have applied since 30 June 2024, and the rest since 30 December 2024. It does not split coins from tokens either. Everything starts as a crypto-asset, “a digital representation of a value or of a right” that can be transferred and stored electronically.
Three groups follow. E-money tokens reference a single official currency. Asset-referenced tokens reference another value or right, or a mix of them. Everything else falls into the “other crypto-assets” bucket, which holds bitcoin and utility tokens alike. Tokenized shares and bonds stay under the EU’s existing securities rules. Our explainer on the MiCA regulation goes through the details.
UK: FCA token types and HMRC
The FCA’s guidance of July 2019, PS19/22, uses four types. Exchange tokens such as bitcoin, used as a means of exchange, usually fall outside its perimeter. Utility tokens give access to a current or future product or service. Security tokens carry rights similar to shares or debt and sit inside the perimeter. E-money tokens come under the e-money rules.
So in British regulatory language bitcoin is an exchange token, and almost everything is a token, the reverse of CoinGecko calling everything a coin. HMRC uses similar labels and says tax treatment depends “on the nature and use of the token and not the definition of the token”.
The rules are about to widen. The FCA’s new regime for crypto firms starts on 25 October 2027, under the Cryptoassets Regulations 2026, and firms can apply for authorisation between 30 September 2026 and 28 February 2027.
France and Italy apply MiCA through their own supervisors and tax token swaps in their own way; our French and Italian editions cover those rules.
Swapping one token for another is usually a tax event
Tax offices look at disposals, not at whether an asset is a coin or a token. What follows is a general description, not tax advice.
In the United States, the IRS says digital assets “are considered property, not currency.” The digital asset question on Form 1040 must be answered “Yes” if you exchanged one digital asset for another, so swapping ETH for USDT, or one token for another, is a taxable disposal. Stablecoins and NFTs count as digital assets. Brokers report gross proceeds on Form 1099-DA for transactions from 1 January 2025, and cost basis for certain transactions from 1 January 2026.
HMRC takes the same line in the UK. Its Cryptoassets Manual lists “exchanging tokens for a different type of token” as a disposal, next to selling for money, paying for goods or services and giving tokens away (gifts to a spouse or civil partner aside). Moving tokens between wallets you own is not a disposal.
Keep a record of each swap with its date, the amounts on both sides and the fee paid in the native coin. You will need them to work out gains.
Five mistakes that cost beginners money
Sending on the wrong network
Most exchanges let you withdraw USDT on several networks, and the receiving side must use the same one. Ethereum, BNB Smart Chain, Arbitrum and other EVM chains share the 0x address format, so an Ethereum address looks perfectly valid on BNB Smart Chain. Whether funds sent to the wrong EVM network come back depends on who controls the address. With a self-custody wallet, the same key often reaches the funds on the other chain. An exchange deposit address may never credit a network the exchange does not support.
Pick the network first, then copy the address. For a large amount, send a small test transfer and wait for it to arrive. The same check applies the first time you buy crypto on an exchange and move it to your own wallet.
Holding tokens with no coin for gas
A wallet holding USDT on Ethereum and zero ETH is stuck. So is USDT on Tron with no TRX or Energy, and any SPL token without SOL. Keep a small amount of the native coin on every chain where you hold tokens.
Trusting a ticker or a lookalike address
Fake tokens copy names, symbols and logos. Address poisoning goes further: attackers send tiny or zero-value transfers, sometimes of spoofed tokens, from addresses that share the first and last characters of one you use, hoping you copy the wrong one from your history. An Etherscan article of 9 March 2026 puts the success rate at about 1 in 10,000 attempts. It cites a 2025 study that counted about 17 million attempts on Ethereum between July 2022 and June 2024, with at least $79.3 million lost.
Check the middle characters as well, or use a saved address book. Our guide to avoiding crypto scams lists other tricks, including “recovery services” that ask for your seed phrase after a mistake.
Leaving unlimited approvals open
Many apps ask for an unlimited allowance to save you a step later. If that app’s contract is ever exploited, the attacker can spend those tokens without asking you again. Etherscan’s Token Approval Checker lists your ERC-20, ERC-721 and ERC-1155 approvals, shows what is at risk and lets you revoke them. Each revocation is a transaction, paid in ETH.
Getting decimals wrong
Balances are stored as whole numbers, and the decimals setting tells wallets where to put the point. The TON documentation warns that ignoring decimals “can result in sending 1000 times the intended amount”. Wallet apps handle this for you. Scripts and manual contract calls do not.
Next on the path: altcoins
The next lesson on this path looks at altcoins, the name for crypto-assets other than bitcoin, coins and tokens alike. Until it is published, our glossary entry on what an altcoin is gives the definition, and the fee test from this lesson already tells you which of them run their own chain.
