Tokens vs. Native Coins
Why USDC lives on an Ethereum address, why you need some ETH (or TRX, or SOL) just to move it, and why tokens work a little differently from chain to chain.
Updated Oct 22, 2026
Native coins
A is built into its blockchain and pays for transactions there: BTC on Bitcoin, ETH on Ethereum, ADA on Cardano, SOL on Solana, TRX on TRON.
Tokens
A is created by a running on someone else's chain. USDC and USDT are tokens on Ethereum, TRON, Solana, and other chains. Your token balance sits at the same address as your native coin.
- Your ETH address receives ETH and Ethereum tokens like USDC and USDT.
- On Crypto Barter you add one ETH address and pick which tokens it accepts.
You need the native coin for fees
Moving a token still costs a fee, paid in the chain's native coin. If you hold $500 of USDC on Ethereum but zero ETH, you can't send the USDC until you add a little ETH.
Keep a small amount of the native coin in any wallet that holds tokens, so you can always move them.
Not every chain works the same way
On most chains a token is a smart contract. A few chains build tokens into the ledger itself, and some ask you to keep a small amount of the native coin alongside each token you hold. Your wallet handles this for you, but it explains small amounts you might see moving with a token.
How this works on Ethereum, Solana, TRON, Cardano
- Ethereum
Tokens are smart contracts (ERC-20). Fees are paid in ETH as gas.
More on Ethereum - Solana
Tokens (SPL) sit in token accounts that need a small refundable SOL deposit.
More on Solana - TRON
Tokens like USDT are smart contracts (TRC-20). Fees are paid in TRX.
More on TRON - Cardano
Tokens are native assets tracked by the ledger, and each travels with a small amount of ADA.
More on Cardano
Same token, different networks
USDC on Ethereum and USDC on Solana are the same dollar token but live on different networks. They can't be sent directly from one to the other. Always match the on both sides (see the Networks lesson).
Key takeaways
- Native coins pay fees; tokens ride on top.
- Token balances share the native coin's address.
- Keep a little native coin for fees.
- Some chains keep a small amount of the native coin with each token.
