# List supported tokens

> List ERC-20 assets enabled by the active Core deployment.

`GET /core/tokens`

<Tooltip headline="ERC-20" tip="Ethereum's standard interface for fungible tokens. It defines common functions for balances, transfers, approvals, and allowances so wallets and applications can interact with tokens consistently.">ERC-20</Tooltip> assets use token contract addresses and decimal precision instead of the native ETH balance.

Use the returned token address and decimals when constructing payment
requirements and signed guarantees.
