sendTransaction

sendTransaction RPC Method

post

Submits a signed transaction to the cluster for processing and returns the transaction signature if successful. This is the primary method for executing transactions on the Solana network. The transaction must be fully signed and serialized before submission. The method provides various options for controlling transaction processing behavior, including preflight checks, retry logic, and encoding formats. Transactions that fail preflight checks or network validation will return detailed error information.
