From fdfc7e54c55164ef393658ffa8d11d53d0607edd Mon Sep 17 00:00:00 2001 From: Artemii Gerasimovich Date: Fri, 8 May 2026 00:42:49 +0200 Subject: [PATCH 01/49] contracts-bedrock: add Espresso BatchAuthenticator and supporting infra Adds the Espresso-introduced contracts and the minimum supporting changes required for them to compile, test, and pass the contract checks. New contracts and scripts: - src/L1/BatchAuthenticator.sol and interfaces/L1/IBatchAuthenticator.sol (upgradeable contract that authenticates batch transactions, with switching between Espresso and fallback batchers) - scripts/deploy/DeployBatchAuthenticator.s.sol and scripts/deploy/DeployEspresso.s.sol - test/L1/BatchAuthenticator.t.sol and test/mocks/MockEspressoTEEVerifiers.sol - snapshots/{abi,storageLayout}/BatchAuthenticator.json - snapshots/semver-lock.json entry for BatchAuthenticator New submodules: - lib/espresso-tee-contracts (interfaces required by BatchAuthenticator) - lib/openzeppelin-contracts-upgradeable-v5 (OZ v5 used by BatchAuthenticator via OwnableUpgradeable) Supporting changes (Espresso-driven): - foundry.toml: remappings for OZ v5 and espresso-tee-contracts; ignored warning codes for vendored libs; OOM-safe jobs settings; via-ir profile. - justfile: fix-proxy-artifact recipe to handle OZ v5 shadowing Proxy/ProxyAdmin artifacts; build/coverage hooks. - src/universal/Proxy.sol, src/universal/ProxyAdmin.sol: pin pragma to exact 0.8.15 so they stay in their own compilation group and never emit PUSH0. - src/universal/ReinitializableBase.sol: loosen pragma to ^0.8.15 so BatchAuthenticator (compiled with OZ v5) can import it. - scripts/* and test/*: disambiguate Proxy artifact lookups to src/universal/Proxy.sol:Proxy (avoids OZ v5 proxy/Proxy.sol shadow). - scripts/checks: bypass interface checks for artifacts originating from lib/; add Espresso-related contract names to exclude lists; pragma exclusions for Proxy/ProxyAdmin/BatchAuthenticator. - test/vendor/Initializable.t.sol: exclude BatchAuthenticator (deployed by a separate Espresso script).

From a8824467edf2f4f0e6fe0909e1d364b098099871 Mon Sep 17 00:00:00 2001 From: Paul Lange Date: Wed, 20 May 2026 15:39:20 +0200 Subject: [PATCH 12/49] contracts-bedrock: drop OZ TUP from espresso deploy Inline the EspressoTEEVerifier deployment in DeployEspresso.s.sol so it no longer imports lib/espresso-tee-contracts/scripts/DeployTEEVerifier.s.sol or DeployNitroTEEVerifier.s.sol. The upstream scripts pulled OZ v5's TransparentUpgradeableProxy (and its auto-deployed ProxyAdmin) into the OP artifact tree, shadowing src/universal/ProxyAdmin.sol and forcing a ~90-line fix-proxy-artifact justfile recipe. The TEEVerifier is now deployed behind src/universal/Proxy.sol + src/universal/ProxyAdmin.sol, matching how BatchAuthenticator is deployed in the same script. ERC-1967 slots are unchanged, so external callers see no difference. The raw vm.getCode("ProxyAdmin") lookups in the deploy scripts and BatchAuthenticator tests are switched to the explicit artifact path vm.getCode("forge-artifacts/ProxyAdmin.sol/ProxyAdmin.json") to deterministically resolve the default compilation profile's bytecode (the dispute profile transitively compiles ProxyAdmin at optimizer_runs=5000, creating a second artifact that broke unqualified lookups). The fix-proxy-artifact recipe and its 5 callsites are removed. --- packages/contracts-bedrock/justfile | 112 +----------------- .../deploy/DeployBatchAuthenticator.s.sol | 3 +- .../scripts/deploy/DeployEspresso.s.sol | 91 +++++++++----- .../test/L1/BatchAuthenticator.t.sol | 4 +- 4 files changed, 69 insertions(+), 141 deletions(-) diff --git a/packages/contracts-bedrock/justfile b/packages/contracts-bedrock/justfile index abf3d1dcf2d..cf98fe6d804 100644 --- a/packages/contracts-bedrock/justfile +++ b/packages/contracts-bedrock/justfile @@ -38,10 +38,6 @@ forge-build *ARGS: --skip-simulation \ 2>/dev/null || true - @# lib/espresso-tee-contracts uses OZ v5 TransparentUpgradeableProxy, which causes Foundry - @# to emit shadow ProxyAdmin/Proxy artifacts that break vm.getCode lookups.

This removes the impl closure (TEEHelper, JournalValidation, and the aws-nitro-enclave-attestation chain) from OP's solc invocations. The impls are still parsed/ABI-checked by forge via libs=['lib'], but they no longer require bytecode emission or the optimizer backend. Since OP's build no longer compiles the submodule's impl files, the three error codes those files triggered (6321 unnamed return, 5667 unused param, 1878 missing SPDX) can be removed from ignored_error_codes. OP's own code does not trigger any of them. The lint_on_build=false workaround is also removed for the same reason — with the impl closure gone, forge lint reports 283 warnings (all from OP's own code), none of which cause a build failure. Adds fs_permissions read access for lib/espresso-tee-contracts/out/ so vm.getCode can locate the pre-built artifacts. The submodule must be built (forge build --root lib/espresso-tee-contracts) before OP's main build.

Both proxies use the deployer as a transient admin to initialize directly, then changeAdmin to the shared ProxyAdmin (DeployAltDA/DeployFeesDepositor pattern). Reorder TEE deploy so the Nitro verifier is wired via initialize, removing the post-init onlyOwner call and ownership-transfer dance. Rename inputs to espressoOwner/sharedProxyAdmin and drop the teeVerifierProxyAdmin output.

Stacks on the contracts PR. Introduces an L2-timestamp hardfork (EspressoEnforcementTime) gating all post-fork derivation semantics. Pre-fork, derivation behaves exactly as upstream Optimism: batches are accepted based on the L1 transaction sender matching the SystemConfig batcher address. Post-fork, batches are authenticated via BatchInfoAuthenticated(bytes32) events emitted by the BatchAuthenticator contract, and sender-based authorization is rejected. Adds CollectAuthenticatedBatches which scans L1 receipts over a configurable lookback window (default 100 blocks) to build the set of authenticated batch commitment hashes for each L1 block being derived. Results are cached in two reorg-safe (block-hash-keyed) LRU caches: one for receipt-derived event sets, one for L1BlockRef resolution. For consecutive L1 blocks the lookback windows overlap by ~99 blocks, so only one new block's receipts need to be fetched on each call. Adds rollup.Config fields: EspressoEnforcementTime *uint64, BatchAuthenticatorAddress, BatchAuthLookbackWindow. Adds unit tests for batch authentication across calldata, blob, and altda data sources.

The contract event changed from BatchInfoAuthenticated(bytes32 indexed commitment) to BatchInfoAuthenticated(bytes32 commitment, address indexed caller): the signature hash (Topics[0]) changes, the commitment moves into the unindexed log data, and the caller becomes the indexed Topics[1]. The event scanner is updated accordingly (new ABI string, commitment read from Data[:32], with a length guard). CollectAuthenticatedBatches and collectAuthEventsFromReceipts now return map[commitment]caller instead of a commitment set. Post-fork, isBatchTxAuthorized recovers the batch transaction's L1 sender and accepts the batch only if it equals the caller that emitted the auth event. This binds each batch to the address that authenticated it, so a batch authenticated by one batcher cannot be submitted by another. When the same commitment is authenticated in more than one block within the lookback window, the newest event's caller is retained. Removes FindBatchAuthEvent and its test: it had no production caller (the pipeline uses CollectAuthenticatedBatches) and, lacking a caller check, diverged from the enforced sender-equals-caller semantics. Updates the data-source tests to set the auth event caller to the batch tx sender, and adds cases covering acceptance for a non-batcher sender matching its caller, rejection when the sender differs from the caller, and newest-caller-wins on duplicate authentication.

This eliminates the global mutable state, the cache-size-locked-by-first-caller problem, and the data race in resetBatchAuthCaches.

Both data sources gate event-based authentication on IsEspresso(ref.Time), and each implements that gate separately, but no test exercised the gate flipping across activation or verified that multiple batches are matched to their own commitments. Fork-boundary tests (TestDataFromEVMTransactionsForkBoundary for the calldata source, TestDataAndHashesFromTxsForkBoundary for the blob source) reuse a single DataSourceConfig with EspressoTime set and vary only ref.Time across the activation boundary: - pre-fork (ref.Time < EspressoTime): the batcher tx is accepted via upstream sender-based auth, and an empty L1 mock asserts that zero receipt scanning occurs; - non-batcher senders remain rejected pre-fork; - activation block (ref.Time == EspressoTime): the same batcher tx is rejected without a BatchInfoAuthenticated event and accepted with one. This pins the ">=" gate in both directions: a regression to ">" makes the activation block either accept an unauthenticated batch or skip the event scan, failing the test. The blob-source copy drives a type-2 calldata tx, the shape an Ecotone-active, calldata-batching chain (e.g. Celo) submits through the blob source. TestDataFromEVMTransactionsEventAuth gains a "multiple authenticated txs each accepted for their own commitment" case: two distinct batches, each authenticated by its own commitment, must both be accepted in order and mapped to their own data, verifying each tx is matched against its own commitment rather than to "some" authenticated entry.

Computes the batch commitment hash from either calldata or concatenated blob versioned hashes. - op-batcher/batcher/espresso_active.go: hasBatchAuthenticator (does this rollup use BatchAuthenticator at all?) and isFallbackAuthRequired (gates fallback authentication on Config.IsEspresso(tip.Time + lead)). The Espresso hardfork predicate is consulted with the configured FallbackAuthLeadTime added to the L1 tip, so the batcher starts authenticating slightly before the verifier requires it. This absorbs worst-case L1 inclusion delay between the batcher's decision time (L1 tip) and the verifier's evaluation time (containing L1 block). - op-batcher/batcher/espresso_driver.go: the authGroup bookkeeping (initAuthGroup, waitForAuthGroup, fallbackAuthGroupLimit) and the dispatchAuthenticatedSendTx fan-out used by driver.go sendTx. Small wiring edits to upstream files: - op-batcher/flags/flags.go: register --espresso.fallback-auth-lead-time (default 5m). - op-batcher/batcher/config.go: thread the FallbackAuthLeadTime through CLIConfig. - op-batcher/batcher/service.go: BatcherConfig.FallbackAuthLeadTime field, propagated from CLIConfig in initFromCLIConfig. - op-batcher/batcher/driver.go: extend L1Client to embed bind.ContractBackend (required by the BatchAuthenticator binding), add authGroup field to BatchSubmitter, call initAuthGroup in NewBatchSubmitter, call dispatchAuthenticatedSendTx in sendTx, call waitForAuthGroup in publishingLoop's shutdown drain. - op-batcher/batcher/driver_test.go: embed bind.ContractBackend in fakeL1Client so the AltDA tests still satisfy L1Client. The fallback batcher does nothing when the rollup config has no BatchAuthenticator address, and it falls through to the upstream queue.Send path pre-EspressoTime. Cancel transactions always take the upstream path. No new external dependencies are added; the only third- party Go modules needed are already in PR #445. The TEE batcher is a separate PR stacked on top.

EspressoBatch type and converters Introduce op-node/rollup/derive/espresso_batch.go defining EspressoBatch (a SingularBatch with block number, L1 info deposit transaction, and signer address attached), along with BlockToEspressoBatch and the unmarshaler used by the streamer. Also pulls in the github.com/EspressoSystems/espresso-network/sdks/go dependency, which provides the Espresso transaction and namespace types. Consumed by the Espresso batcher (next commits) to convert L2 blocks into batches submitted to Espresso, and to round-trip those batches back through the streamer.

(The --espresso.fallback-auth-lead-time flag lives in op-batcher/flags/flags.go and was added by the fallback PR.) - espresso/interface.go: EspressoStreamer[B] interface that wraps github.com/EspressoSystems/espresso-streamers/op.BatchStreamer. - espresso/ethclient.go: AdaptL1BlockRefClient adapter (used by cli.go to construct the streamer) and FetchEspressoBatcherAddress helper. Also adds the EspressoSystems/espresso-network/sdks/go and EspressoSystems/espresso-streamers Go module dependencies. The regenerated BatchAuthenticator bindings already live in the fallback PR's espresso/bindings/.

TEE batcher and Espresso submission loop Add the Espresso TEE batcher write-path on top of the fallback batcher: - op-batcher/batcher/espresso.go: Espresso submission loop (peeks the channel manager, converts each L2 block to an EspressoBatch, submits it to Espresso, waits for inclusion, and then posts the batch txs to L1 with TEE-attested BatchAuthenticator.authenticateBatchInfo calls). - op-batcher/batcher/espresso_service.go: EspressoBatcherConfig, initEspresso (Espresso client / light-client construction, optional TEE attestation gathering), and the initChainSigner hook that wraps the txmgr into a opcrypto.ChainSigner. - op-batcher/batcher/espresso_helpers_test.go and espresso_transaction_submitter_test.go: unit tests for the helpers and the TEE transaction submitter. Extends the existing fallback wiring: - op-batcher/batcher/espresso_driver.go: adds EspressoDriverSetup fields (Client/LightClient/ChainSigner/SequencerAddress/Attestation), batcherL1Adapter, setupEspressoStreamer, startEspressoLoops, resetEspressoStreamer; extends dispatchAuthenticatedSendTx with the TEE branch (always authenticates when Espresso.Enabled). - op-batcher/batcher/espresso_active.go: adds isBatcherActive (queries BatchAuthenticator.activeIsEspresso to gate publishing against this batcher's role). - op-batcher/batcher/driver.go: extends DriverSetup with the Espresso EspressoDriverSetup field; adds espressoSubmitter / espressoStreamer / teeVerifierAddress / degradedLog fields on BatchSubmitter; calls setupEspressoStreamer in NewBatchSubmitter; branches StartBatchSubmitting on Espresso.Enabled to call startEspressoLoops; calls resetEspressoStreamer in clearState. - op-batcher/batcher/service.go: BatcherConfig.Espresso field; EspressoClient / EspressoLightClient / ChainSigner / Attestation runtime fields; initEspresso / initChainSigner / applyEspressoDriverSetup call-outs. - op-batcher/batcher/config.go: thread Espresso espresso.CLIConfig through CLIConfig. - op-batcher/flags/flags.go: register espresso.CLIFlags (TEE-only flags; the --espresso.fallback-auth-lead-time flag added by the fallback PR continues to live in op-batcher/flags/flags.go). Also adds op-service/log/repeat_state.go (RepeatStateLogger) and its test, used by the Espresso submission loop's tick-driven warnings. A safeTestRecorder helper is inlined into the test to avoid pulling in the unrelated debouncer. Adds the github.com/hf/nitrite dependency (transitively required by hf/nsm for attestation document parsing).
