- Introduce a new subscription kind `transactionReceipts` to allow clients to receive transaction receipts over WebSocket as soon as they are available. - Accept optional `transactionHashes` filter to subscribe to receipts for specific transactions; an empty or omitted filter subscribes to all receipts. - Preserve the same receipt format as returned by `eth_getTransactionReceipt`. - Avoid additional HTTP polling, reducing RPC load and latency. --------- Co-authored-by: Sina Mahmoodi <itz.s1na@gmail.com>
New RPC method eth_sendRawTransactionSync(rawTx, timeoutMs?) that submits a signed tx and blocks until a receipt is available or a timeout elapses. Two CLI flags to tune server-side limits: --rpc.txsync.defaulttimeout (default wait window) --rpc.txsync.maxtimeout (upper bound; requests are clamped) closes ethereum/go-ethereum#32094 --------- Co-authored-by: aodhgan <gawnieg@gmail.com> Co-authored-by: Sina Mahmoodi <itz.s1na@gmail.com>
Add `SubscribeTransactionReceipts` for ethclient. This is a complement to ethereum/go-ethereum#32697.
