The Blockchain API is the RPC service that powers AppKit's blockchain functions such as account balances, ENS resolution, transaction history, and more.
info
Blockchain API is not the same as the WalletConnect protocol. WalletConnect protocol supports wallets on all chains using the CAIP-25 standard. We do not accept requests for new chains to be added to our Blockchain API. Please see your SDK's relevant documentation on how to add RPC URLs for chains you want to use that Blockchain API does not.
Features
- AppKit built-in integration
- Multi-chain mainnet and testnets
- HTTP RPC support
- Cloud metrics and reporting
- The Identity API with near-instant ENS resolution
- Transaction history
Supported Chains
The Blockchain API supports popular chains such as Ethereum, Binance Smart Chain, Solana, and more. See the full list of supported chains.
Using the Blockchain API
No config or setup is needed for AppKit integrations. For other usage, see the Usage section.
Limits
The Blockchain API is free for 6 million requests per 30 days.
