Scheduled

We are upgrading our Gnosis Mainnet Nethermind infrastructure to v1.38.0. This is a post-Fusaka (Osaka) maintenance release focused on node robustness, JSON-RPC correctness, and runtime performance improvements.

During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:

txpool_content / txpool_contentFrom / txpool_status — corrected response formatting and hex encoding inconsistencies

eth_call / eth_estimateGas — now correctly honors the gas cap as the default gas value; the block gas limit ceiling no longer applies to RPC calls. Custom revert bytes are also stripped from the message field for cleaner error responses

eth_feeHistory — correctness fixes to response data

trace_transaction / trace_replayTransaction — fixed HTTP 500 errors being returned incorrectly

eth_getBlockByNumber("pending") — now correctly returns non-null values for hash, nonce, and miner fields
