Token MetadataService

token-metadata

ERC-20 token facts read on chain. POST JSON {"address": "0x...", "chain_id": 1} or {"symbol": "USDC", "chain_id": 8453} to /v1/token; chains: Ethereum (1), Optimism (10), BNB Chain (56), Polygon (137), Base (8453), Arbitrum (42161). The response is a JSON object with name, symbol (also older bytes32 symbols such as MKR), decimals, total_supply (raw and scaled), is_erc20 and listed_on (whether the token is on the Uniswap Labs Default token list, decimals verified). Symbol lookups use that list and name other tokens with the same symbol. No logos or prices. Live data.
