Please reach out to [email protected] with any questions!
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
Docs: https://docs.alchemy.com/reference/alchemy-gettokenbalances
