We are upgrading our Nethermind node to v1.37.1. During the maintenance window, brief interruptions to RPC availability may occur. This is a major release with significant performance improvements, new RPC endpoints, a security fix, and several breaking changes to RPC behavior.
RPC Changes: eth_estimateGas — Corrects incorrect gas estimates in certain scenarios.
eth_getBlockByNumber — Now correctly enforces canonical block retrieval.
eth_simulateV1 — fixed Now correctly returns -38015 error code for block gas limit exceeded. Also accepts calls where both input and data are provided.
eth_subscribe — modified New transactionReceipts subscription type added, pushing all transaction receipts when a new block is added.
debug_* and trace_* methods — modified GasCap is now enforced across all debug and trace RPC methods. Block field overrides now supported in debug_ calls.
eth_getStorageValues — note This endpoint was referenced in the Erigon v3.4.0 release — Nethermind has not added this endpoint in v1.37.1.
