eth_getTransactionBySenderAndNonce

POST

/{apiKey}

Returns the hash of the transaction sent by the given sender address at the specified nonce, or null if no such transaction exists. Originally introduced by the Otterscan project (as ots_getTransactionBySenderAndNonce) and now exposed under the standard eth_ namespace. Requires an archive-capable backend because the lookup walks historical account state.
