Apply evmos.diff: trace DB, oe tracer, pre/trace RPC namespaces#1
Conversation
- Add RocksDB trace database in evmd app and pass to VM keeper - Add ReadTxTrace/WriteTxTrace to keeper for oe tracer persistence - Add TraceTx branch for TracerOe to read traces from DB - Add 'oe' to evmTracers in server config - Add Tracer and Args to TransactionArgs; PreResult, TraceStore, ActionTrace types - Add pre and trace JSON-RPC namespaces (TraceMany, trace_transaction) - Handle TracerOe response in backend TraceTransaction (return raw RLP) - Add TracerOe constant to vm types Co-authored-by: Cursor <cursoragent@cursor.com>
- Add batch execution path in EthCall keeper: when TransactionArgs.Args contains sub-calls, iterate and apply each via ApplyMessageWithConfig, returning JSON-serialized []PreResult with logs, gas, and error info - Add rpc/namespaces/ethereum/eth/multicall.go with PublicAPI.MultiCall: supports parallel/sequential execution, fast-fail, native token shortcut, and per-call timing stats Co-authored-by: Cursor <cursoragent@cursor.com>
When the keeper's tracer is set to "oe", ApplyTransaction now creates a callTracer via go-ethereum's tracers.DefaultDirectory, passes its hooks into ApplyMessageWithConfig, and after execution persists the JSON- serialized trace result to the keeper's traceDb keyed by tx hash.

The trace result from flatCallTracer is now RLP-encoded via rlp.EncodeToBytes before writing to traceDb, matching the RLP decoding used on the read path in trace_transaction. Co-authored-by: Cursor <cursoragent@cursor.com>
- Create a flatCallTracer per sub-call in ethCallBatch and pass its hooks into ApplyMessageWithConfig to collect structured call traces - Collect trace result via GetResult() and store as json.RawMessage in PreResult.Trace - Update PreResult.Trace type from []ActionTrace to json.RawMessage to hold the raw tracer output directly Made-with: Cursor
