We are updating our Monad Testnet infrastructure to Monad v0.14.1. During the maintenance window, brief interruptions to RPC availability may occur.
RPC Changes: eth_fillTransaction — new endpoint Returns a fully populated transaction (gas, nonce, fees, etc.) without requiring a signature. Useful for transaction preparation flows. eth_fillTransaction — modified Calls that fail due to insufficient reserve balance now return reserve balance violation instead of insufficient balance. Callers matching on the exact error string should update accordingly. Gas estimation for omitted-gas fills is also now more permissive. WebSocket subscriptions — modified newHeads and logs subscriptions now emit on proposed blocks instead of voted blocks, reducing notification latency. Clients with timing-sensitive subscription logic should account for the earlier emission point. eth_getLogs block tags — fixed Block tag handling in eth_getLogs has been corrected. Queries using tags like latest or pending may return different results than before if previous behavior was incorrect.
