Add EIP-4844 blob transaction support to op-reth, enabling blob transactions on L2 chains when l2BlobTime is configured. Type system changes (op-alloy): - Add Eip4844 variant to OpPooledTransaction, OpTxEnvelope, OpTypedTransaction, OpTxType, OpReceipt, OpReceiptEnvelope - Add try_into_pooled_eip4844() for consensus-to-pooled conversion - Update all exhaustive match arms across op-alloy, alloy-op-evm, op-reth crates Transaction pool (op-reth): - Implement take_blob(), validate_blob(), try_into_pooled_eip4844(), try_from_eip4844() for OpPooledTransaction - Add TakeBlobSidecar trait for sidecar extraction in from_pooled() - Add IntoPooledEip4844 trait for sidecar attachment - Gate blob txs on is_l2_blob_active_at_timestamp in validator and node builder (no_eip4844 when inactive) Payload builder (op-reth): - Collect blob sidecars during block building via take_blob() on pool txs before consensus conversion - Return sidecars in BlobsBundle in engine API getPayload response - Remove unconditional blob tx rejection from payload validator Block execution (alloy-op-evm): - Track actual blob_gas_used separately from da_footprint_used - Set blob_gas_used in block header from EIP-4844 tx blob gas Chain config (op-reth): - Parse l2BlobTime from genesis config.optimism - Add is_l2_blob_active_at_timestamp() to OpHardforks - Conditionally enable EIP-4844 in txpool validator External dependencies: - QuarkChain/reth l2_blob: add Eip4844 match arms in reth-codecs and reth-primitives-traits - QuarkChain/evm l2_blob: add Eip4844 match arms in alloy-evm op module (FromRecoveredTx, FromTxWithEncoded for OpTxEnvelope) Acceptance tests: - Add l2blob test under op-acceptance-tests/tests/l2blob/ - Add l2blob gate in acceptance-tests.yaml - Add justfile recipes for sgt and l2blob with op-reth env vars - Add DACUrls support to devstack L2CLConfig for DAC server config - Start DAC server in test init for blob upload/download verification Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
