EIP-7966 proposes a new JSON-RPC method called eth_sendRawTransactionSync for Ethereum clients. This method allows submitting a signed raw transaction and waiting synchronously for the transaction receipt (or until a configurable timeout), rather than the current asynchronous approach with eth_sendRawTransaction where clients must poll separately for confirmation.
The key benefits include:
- Reduced latency: By combining transaction submission and receipt retrieval into a single RPC call, it cuts down the overall time for confirmation feedback by approximately 50%, which is especially valuable in low-latency environments like Layer 2 solutions or high-frequency blockchains.
- Simplified developer experience: It eliminates the need for client-side polling logic, making it easier to build decentralized applications (dApps) and wallets without handling repeated checks for transaction status.
- Lower network overhead: Fewer separate RPC calls mean reduced strain on the network, improving efficiency for both users and nodes.
- Improved user experience: Applications can provide faster, more responsive feedback on transaction confirmations, aligning better with traditional web request-response patterns.
- Stronger delivery guarantees: It offers opt-in synchronous behavior with timeouts, helping in scenarios where quick assurances are needed without breaking existing asynchronous workflows.
- Backwards compatibility: The method is optional and doesn't alter existing APIs, so it can be adopted gradually without disrupting current systems.
