Welcome to the Besu Ethereum Execution Layer Client
There are now two RPC APIs in Execution Clients:
-
Querying API (port 8545): Use this endpoint to query transactions on your node and connect to it with your web3 wallet.
-
Engine API (port 8551): Use this endpoint to connect your Beacon Chain (Consensus Layer) client.
If your Execution Client is not connected to a Consensus Layer client, you won't be able to keep it synced, nor use it to query the blockchain, nor will you be able to connect your wallet to it!
