Use case 1: token balances & metadata
Our token APIs are a perfect replacement for SimpleHash’s fungible token endpoints.
Our fungible token APIs provide: ✅ Real-time balances for ERC-20 and other tokens
✅ Token metadata (name, symbol, decimals, contract address)
✅ Multi-chain support for all major blockchains
