Reth v2.11.0

Summary

Reth v2.11.0 is a hardening and performance release. RPC calls that can do unbounded work are now capped or cancellable (eth_callMany, trace_callMany, debug_traceCallMany, eth_getProof, mev_simBundle, eth_simulateV1), and the release brings a broad set of transaction pool, P2P and storage correctness fixes. EIP-7702 authorization recovery is parallelized, P2P skips decoding responses it never asked for, and overlay provider setup is cheaper.

SDK users: Ethereum block execution now runs on evm2::block, and reth's executor types are thin adapters over it (see Breaking Changes).

Action Required

• Removed no-op CLI flags. The node now refuses to start if you still pass --engine.legacy-state-root, --engine.caching-and-prewarming, --engine.parallel-sparse-trie, --engine.disable-parallel-sparse-trie, --engine.precompile-cache or --rpc-cache.max-headers (alias --rpc-cache.max-envs). Drop them from your config (#28369)

• With --instance N and no explicit --auth-ipc.path, the Engine API IPC socket is now /tmp/reth_engine_api.ipc-N. Set --auth-ipc.path if your consensus client expects the old path (#28257)

• Explicit IPC socket permissions are now validated at startup, and an invalid mode is a startup error. On platforms that can't set the mode before binding (including macOS), explicit permissions fail startup (#28326)

• eth_callMany, trace_callMany and debug_traceCallMany now allow at most 1,024 calls and share one --rpc.gascap budget across the request. No additional call starts more than five seconds after the first. Previously successful requests may now fail; callers should review request sizes and gas budgets (#28314)

• eth_getProof now allows at most 1,024 storage keys. eth_getMultiProof allows at most 1,024 targets and 1,024 storage keys in total. Requests exceeding these limits fail with invalid params (#27716)

Backwards Compatibility

Verification pending: Database migration and resync requirements, and supported downgrade versions, must be confirmed against the final v2.11.0 release build before publication.

Breaking Changes

SDK

• Ethereum block execution moved into evm2::block: BundleState, BlockState/StateUpdate, the block execution errors, GasOutput/CommitChanges and the Ethereum executor now come from evm2, and EthBlockExecutor wraps evm2::block::ethereum::EthBlockExecutor. EthApiError::MuxTracerError now holds the error message (#28238)
• MessageInput no longer dereferences to bytes. Custom precompile integrations should read inputs through Evm::message_input (#28413)
• Discovery dependencies moved to discv5 0.12, ENR 0.14 and secp256k1 0.33. Downstream integrations using public discovery/key types must update their dependency versions and key APIs (#28289)
• EnrCombinedKeyWrapper implements TryFrom<Enr<SecretKey>> instead of From, and Discv5::add_node returns Error::InvalidEnr for records the discv5 key backend rejects (#28345)
• RpcServerArgs::auth_ipc_path is now Option<String>; read the effective endpoint with auth_ipc_path() (#28257)
• schnellru caches are replaced with reth-lru (#28291)
• Removed the unused DEFAULT_HEADER_CACHE_MAX_LEN constant (#28369)

Features

Performance

• Parallelized EIP-7702 authorization recovery (#28307)
• P2P skips decoding responses that weren't requested (#28403)
• Reduced overlay provider setup and state-sharing overhead (#28373, #28333)
• The engine's balance tracker only steps on the opcodes it needs (#28334)
• Replaced schnellru with the faster reth-lru caches (#28291)
• Reduced RPC serialization and authentication overhead (#28295, #28294)

RPC

• Block transaction replay now runs through the block executor (#28266)

Transaction Pool

• Subscribers can follow events of transactions held outside the pool (#28387)

Bug Fixes

RPC

• mev_simBundle work is bounded (#28386)
• eth_simulateV1 stops once its request is dropped (#28312), checks cancellation once per simulated block (#28390) and picks each simulated block's fork from its timestamp (#28431)
• The default eth_call gas limit is capped, so calls without gas no longer fail with intrinsic gas too high under --rpc.gascap max on Amsterdam (#28315)
• The builder validation API defaults to a 3-block validation window; --rpc.eth-proof-window can only widen it (#28424)
• eth_sendTransaction serializes nonce assignment (#28418)
• Transactions with conflicting fee fields are rejected (#28324)
• Consensus errors map to invalid params (#28398)
• testing_buildBlockV1 skips blob transactions (#28379)
• Namespace checks honor the default HTTP, WS and IPC module sets (#28327)
• debug_intermediateRoots replays bad blocks (#28331)
• Fixed a tracer panic on frameless logs (#28330)
• Restored depth-zero root handling in tracers and tracing of unlisted precompiles as contracts (#28389)
• Retained receipt history is reported correctly (#28201)

Transaction Pool

• Transactions exceeding the local size limit remain rejected, but no longer penalize the relaying peer (#28355)

• Pending sessions and the listener get a turn under load (#28332)
• netrestrict applies to startup peers (#28198)
• DNS discovery retries links whose initial root lookup failed (#28346) and handles whitespace in entries (#28310)
• Discv5 ENR conversion no longer panics on unsupported key encodings (#28345)
• The status payload is truncated in handshake decode logs (#28322)

Storage & Pruning

• Stages unwind on unrecoverable senders (#28420)
• Fixed a lock inversion in the MDBX read transaction timeout monitor (#28254), and the monitor stops when the environment is dropped (#28404)
• Snap trie reverts are no longer cached (#28401)
• Snap ranges are refused on unverified state (#28392)
• Interrupted genesis initialization resumes (#28376)
• Static file truncation is deferred on reorg (#28370)
