eth_sendTransaction - BSC

Example code for the eth_sendTransaction JSON RPC method. Сomplete guide on how to use eth_sendTransaction JSON RPC in GetBlock Web3 documentation.

This method requires the sender account to be unlocked on the node. This method is not available on public RPC endpoints (for example GetBlock). For public RPCs, use eth_sendRawTransaction with a locally signed transaction.
