Feb 1, 2025February 2025 — iotaledger/wasp: Stabilized core RPC paths, hardened error handling, and enabled durable chain-state persistence. Key outcomes include an on-disk SaveDB persistence (RocksDB) for the chain state, a fix to Eth_Call block anchor resolution that uses the correct anchor state for a given block number, and a broad set of JSON-RPC robustness and tracing fixes to prevent panics, handle missing blocks and nil queries, and improve trace accuracy for failed transactions. Tests were updated to cover multiple block states and failure scenarios, improving regression safety. These changes reduce crash surfaces, enhance data integrity, and enable simpler backups and recovery.
