ERC-20

ERC-20 is the token standard that defines a common interface for fungible tokens on EVM chains, including balance, transfer, and approval methods and events.

ERC-20 specifies the functions and events every fungible token contract should implement, such as balanceOf, transfer, approve, and transferFrom, plus Transfer and Approval events. Because the interface is uniform, wallets, exchanges, and indexers handle any compliant token the same way. Balances live in contract storage, not in the base ledger, so tracking them means reading contract state and decoding Transfer logs. Our decoded data resolves ERC-20 transfers and approvals into named events with token, sender, recipient, and amount, so you index token movement without hand-parsing logs.
