Question

When interacting with a node via JSON-RPC, which specific method is required to retrieve the current state of the mempool for a pending transaction hash?

Accepted Answer

To retrieve the current state of a transaction that is currently in the mempool, you must use the eth_getTransactionByHash method. The mempool, or memory pool, is the holding area where a node stores transactions that have been submitted by users but have not yet been included in a block on the blockchain. When you provide a specific transaction hash to the eth_getTransactionByHash method, the node searches its local mempool for that identifier. If the transaction exists in the mempool, the method returns a JSON object containing the transaction details, including the from address, to address, value, and nonce. If the transaction has not yet been processed by the network and is still waiting, the blockHash, blockNumber, and transactionIndex fields in the returned object will be null, which explicitly confirms the transaction is currently pending in the mempool. If the transaction is not found in the mempool and has not been mined into a block, the method returns null.
