Scheduled

We are upgrading our Monad node to v0.14.2. During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes

debug_* trace methods — modified Log entries in debug call tracer output now include an index field reflecting the global log order across nested call frames.

eth_call — modified Now returns an explicit reserve balance violation error instead of a generic failure when a transaction exceeds the sender's reserve balance.

debug_traceCall, debug_traceTransaction and related methods — modified These methods now count toward the eth call rate limit. Clients that heavily use debug endpoints will see those calls reflected in their rate limit usage.

RPC batch request limit — modified The maximum batch request size has been lowered to match Geth's default. Clients sending large batch requests may need to reduce their batch sizes.
