Coin or token: how do you tell them apart?
A coin is the native currency of its own blockchain, like Bitcoin or Ether. A token is built on top of someone else's blockchain, like Uniswap's UNI on Ethereum.
Coin, token, and who pays the fee
ETH is Ethereum's coin. USDC, UNI, LINK and PEPE are tokens that live on Ethereum and use ETH for fees. Free to reuse
Coins pay for activity on their own network. Ether pays transaction fees on Ethereum; SOL pays them on Solana.
Tokens are created by programs called smart contracts on an existing chain. Stablecoins, governance tokens and meme tokens are mostly tokens. They rely on the host chain for security, and you need that chain's coin to pay fees when moving them.
Every coin page on KryptoKap has a Passport showing whether it's a native coin or a token, and which chain it lives on.
How a token is made
On Ethereum, anyone can deploy a contract that follows the ERC-20 standard. The contract keeps a list of balances and rules for transfers, and wallets and exchanges can support it automatically because every ERC-20 token works the same way.
That's why new tokens appear every day. Creating one takes minutes and costs only a network fee, which is also why copies of popular tokens with the same name are common.
What a token depends on
A token inherits its host chain's security, but it adds the risks of its own contract. If the contract has an admin key, someone may be able to mint new tokens, freeze balances or change the rules.
A stablecoin like USDC also depends on its issuer keeping the promised reserves. So when you look at a token, ask two questions. How safe is the chain, and who controls the contract?
One token, several networks
USDC on Ethereum, Solana and Arbitrum is the same brand but three separate contracts. Each version needs its own chain's coin for fees, and the sender and receiver must use the same network. Free to reuse
Many popular tokens exist on more than one blockchain. USDC, for example, is issued by Circle directly on Ethereum, Solana, Arbitrum and many other networks. Each version is a separate contract with its own address. On Ethereum the USDC contract starts 0xA0b8; on Solana its mint address starts EPjF; on Arbitrum it starts 0xaf88.
This has two practical effects. First, the fee coin changes with the network. Sending USDC on Ethereum costs ETH, on Solana it costs SOL, and on Arbitrum it costs ETH again because Arbitrum uses ETH for gas. A wallet holding 500 USDC on Solana and no SOL can't move it. Second, the sender and the receiver must be on the same network. If an exchange's deposit page says USDC on Solana and you withdraw USDC on Ethereum to it, the funds can be lost or stuck until support recovers them, if it can.
There are also bridged and wrapped versions, such as wrapped bitcoin on Ethereum. These are tokens that represent an asset held somewhere else, and they add a custodian or bridge contract as one more thing that has to keep working. Before any transfer, check the network name on both sides, not just the token symbol.
Checking a token on a block explorer
A block explorer shows who controls a token and who holds it. In this example the top 10 wallets own 62%, so the next step is finding out whose wallets they are. Free to reuse
Every token on Ethereum has a page on Etherscan, and most other chains have a similar explorer. Search the contract address, not the name, because copycat tokens with the same name and symbol are common. Take the address from the project's official site or from KryptoKap's coin passport.
On the token page, look for a few things. A green check on the Contract tab means the source code has been published and matches what's deployed, so others can read it. Look for functions named mint, pause, blacklist or owner; if they exist, someone can still change supply or freeze balances. Then open the Holders tab. In our example, the top 10 wallets hold 62% of supply and everyone else 38%.
A high share isn't automatically bad. Exchanges, staking contracts and bridges often top the list, and explorers usually label them. What deserves attention is a large unlabeled wallet, or one tied to the team, that could sell at any moment. If a single team wallet holds 30% and nothing locks it, a sale would hit the price hard. None of these checks make a token safe, but they take five minutes and catch many obvious problems.
Key terms
Native coin
The currency built into a blockchain, used to pay its fees (BTC, ETH, SOL).
Token
An asset created by a smart contract on an existing chain.
Smart contract
A program stored on a blockchain that runs exactly as written.
Token standard
A shared rulebook, like ERC-20 on Ethereum, so wallets can handle any token.
Coin or token says little about value
Which one is worth more. Some tokens are worth more than many coins.
Whether a token is related to its chain. Anyone can launch a token on Ethereum; sharing a chain doesn't mean sharing a team.
Who controls the token. A token's contract may let its creators mint, freeze or change it.
What people get wrong
Tokens aren't automatically less valuable than coins. Some tokens are worth more than many coins.
The same token can exist on several chains. USDC, for example, is issued on many networks.
Why it matters
Knowing whether something is a coin or a token tells you what it depends on, because a token is only as reliable as its chain and its issuer.
Common questions
Why do I need ETH to send a token on Ethereum?
Fees on Ethereum are always paid in ETH, even when the thing you're sending is a different token.
Can a token become a coin?
Yes. Some projects start as tokens on Ethereum, then launch their own blockchain and swap holders over to the new native coin.
Is Bitcoin a coin or a token?
Bitcoin is a coin. BTC is the native currency of the Bitcoin blockchain and pays its fees. Wrapped bitcoin on Ethereum, such as WBTC, is a token that represents BTC held by a custodian, so it depends on that custodian as well as on Ethereum.
Are NFTs tokens?
Yes. An NFT is a token created by a smart contract, usually under the ERC-721 or ERC-1155 standard on Ethereum. The difference is that each one has a unique ID, while every unit of an ERC-20 token is interchangeable with any other.
