What is the difference between a coin and a token?

You have tokens in your wallet but can’t send them because you don’t have any ETH? That’s where the difference between the two terms shows up in practice.

Think of a blockchain as a road. The native coin is usually used to pay the tolls, i.e. the network fees. Tokens are like different kinds of cargo carried on the same road: they use its infrastructure without having an independent network of their own. The analogy doesn’t cover every case, but it helps separate the infrastructure from what is built on top of it.

BTC is the coin of Bitcoin and ETH is the coin of Ethereum. On Ethereum, tokens can also be issued through smart contracts, i.e. programs that run on the blockchain. Such a token may work as a stablecoin, give voting rights in a protocol or be used inside an app. The distinction is about its technical position, not its value or trustworthiness.

Why it matters

When you transfer a regular ERC-20 token on Ethereum from your own wallet, the fee is normally paid in ETH, not in the token you’re sending. So your token balance alone may not be enough to make the transaction. Some services cover or simplify this payment, but that doesn’t change the network’s basic mechanism.

We find the distinction useful mainly because it helps you ask the right questions: which network is the asset on, what are the fees paid in, and what rules govern how it works?

What to watch out for

The same name doesn’t mean the same network or the same asset. A token can exist on several blockchains, with a different contract address on each. Likewise, a representation of BTC on another network is a token with extra mechanisms and risks, not Bitcoin’s native BTC.

In everyday conversation, “token” is also often used as a general term for crypto assets. And a coin isn’t automatically safer than a token. Before a transfer, check that both sender and recipient support the same network and the specific form of the asset.
