}RemovedThe
getRecentBlockhash method was removed in Agave 2.0 and returns Method not found on current validators. Use getLatestBlockhash instead.getRecentBlockhash method returns a recent block hash from the ledger, and a fee schedule that can be used to compute the cost of submitting a transaction using it.
This method is crucial for transaction construction and submission in Solana. The returned blockhash is used to indicate when a transaction was constructed, which is important for security reasons. The fee calculator provides information about the current network fees.

Parameters
This method does not require any parameters.Response
blockhash— a string representing the blockhash of a recent block.feeCalculator— an object containing:lamportsPerSignature— the current fee in lamports per signature.
Use case
A common use case forgetRecentBlockhash is in transaction preparation. When constructing a transaction, you need to include a recent blockhash to ensure the transaction is processed in a timely manner and to prevent replay attacks. The fee calculator information can be used to estimate the cost of the transaction.Last modified on June 22, 2026
