A digital asset issued on an existing blockchain rather than having its own.

Most cryptocurrencies other than Bitcoin, Ethereum, and a few dozen others are tokens, usually on Ethereum, Solana, or a layer 2.

The distinction from a coin is not about importance or market size. It is about whether the asset has its own chain and its own validators, or lives as a record inside someone else's.

How it works

A blockchain has a native asset used to pay for transactions, which is what the network's own consensus issues. Bitcoin on Bitcoin, ETH on Ethereum, SOL on Solana. Everything else on those chains is a token.

On Ethereum and networks compatible with it, a fungible token is a contract implementing the ERC-20 interface: a balance table plus functions for transferring and for granting allowances (source: EIP-20). On Solana, tokens are accounts managed by a shared program rather than individual contracts. See spl token.

Three consequences follow and they are the practical ones.

You need the chain's native asset to move a token. A wallet holding a token and no native asset cannot transact at all, which is a routine way to end up stuck. See gas.

The token inherits the chain's properties. Its settlement speed, its fee level, and its security are the chain's, not the token's.

The same token often exists on several chains as separate contracts, bridged rather than native. The version you hold and the version an exchange accepts have to match. See wrapped token and bridge.

Tokens carry powers set by their issuer. Mint authority, freeze functions, pausable transfers, and upgradeable logic are all common and all visible on chain, and they matter more than the marketing.

Example

Illustrative. You withdraw a token from an exchange to your own wallet on a chain you have not used before. The balance shows correctly. You then try to send it and the transaction fails, because the wallet holds no native asset to pay the fee. Nothing is lost and nothing is broken. The fix is to acquire a small amount of the chain's own asset, which usually means another withdrawal or a swap, and the second withdrawal costs another flat fee. Planning for it in the first withdrawal is cheaper.

Why it matters when you buy

Which chain a token is on decides where you can hold it, what it costs to move, and whether your exchange will send it to the address you have. The chain pages compare the networks, the coin pages show what RampAtlas tracks for each asset, and the buy pages show which venues sell it where you live.

Questions

What is the difference between a coin and a token?

A coin is a chain's own native asset, issued by its consensus and used to pay fees. A token is issued on top of a chain by a contract or program. The line is technical, not a judgment about value.

Why do I need a second asset to move my token?

Because transaction fees are paid in the chain's native asset, not in the token. A wallet with a token balance and no native balance cannot send anything.

Can the issuer freeze my token balance?

Some tokens include that power and some do not. It is set in the contract and visible on chain, which is worth checking on any asset you plan to hold in your own wallet.

  • Address Poisoning and Clipboard Attacks: How They Work and How to Avoid Them

    Address poisoning and clipboard hijacking both attack the same habit, which is copying a destination address from somewhere convenient instead of from the recipient, and both are defeated by verifying the full address at the moment you send rather than recognizing the first and last few characters.

  • How to Use a Block Explorer to Check a Transaction

    A block explorer is a public search engine for a blockchain, and you check a transaction by pasting its hash into the search box and reading three fields: the status, the number of confirmations, and the receiving address.

  • How to Verify a Token Contract Address Before You Buy

    A token's contract address is its only real identity, so verifying one means getting the address from the project's own official channel, confirming the same address independently from a second source, and checking on a block explorer that the contract is what it claims to be before you trade against it.

  • What Is a Memecoin, and Why Most Lose Their Value

    A memecoin is a token whose price rests on attention rather than on revenue, a product, or a claim on any asset, and the structural reason most end up worthless is that attention is the only thing holding the price up and it always moves on to something else.

  • Why Some Coins Aren't Available Where You Live

    Availability is decided twice, once for the country or state you live in and once for each individual asset, so an exchange that is licensed to serve you can still be unable or unwilling to list the specific coin you want.
