Upgrades require approval from both parties. There is no delay on upgrades. The Guardian role for the SuperchainConfig is assigned to the Base Governance Multisig, which can pause and unpause withdrawals. `Base Multisig 1` serves as Incident Responder and can pause withdrawals but cannot unpause or extend pauses. Each pause automatically expires after 3 months if not extended by the Guardian. The single Sequencer actor can be modified by `Base Multisig 1` via the SystemConfig contract. The Base Governance multisig can also recover dispute bonds in case of bugs that would distribute them incorrectly.\n\nState validation runs through the `AggregateVerifier` game type (621), which accepts either an AWS Nitro TEE attestation or an SP1 ZK proof. The TEE prover allowlist in the `TEEProverRegistry` is managed solely by the `Base Coordinator Multisig` (without Base Security Council approval), and a separate Manager EOA can register or deregister enclave signers. The ZK arm routes through a Base-owned SP1 verifier gateway; the Base Governance Multisig can add or freeze verifier routes. The Base Governance Multisig can swap the AggregateVerifier implementation, change the respected game type, blacklist individual games, or retire all in-flight games via the AnchorStateRegistry.",

"Composition": "**8/11**, nested as one of two signers in the 2/2 `Base Governance Multisig` alongside Coinbase's 3/6 `Base Coordinator Multisig`.

"Members public": "**Mapped (10 of 11)** — [Base publishes](https://docs.base.org/base-chain/security/security-council) Aerodrome (JP), Moonwell (BR), Blackbird (US), ChainSafe (CA), Talent Protocol (PT) and Moshicam (US) as entities, plus Seneca (US), Juan Suarez (US), Toady Hawk (CA), Roberto Bayardo (US) and Yele Bademosi (UK) as individuals. One address is unpublished, as are the people who sign for each entity. Five of the six entities are Base-ecosystem projects and two of the individuals are former Coinbase or Base contributors.",
"Charter": "**None** — the [docs page](https://docs.base.org/base-chain/security/security-council) sets out selection criteria, cohort terms and member duties, but no removal procedure, quorum-loss fallback or conflict-of-interest enforcement. Coinbase's [Neutrality Principles](https://www.coinbase.com/blog/coinbases-neutrality-principles-for-base) cover transaction ordering, user assets and exit rights, and do not bind the Council.",
"Can Coinbase bypass the Council?": "**Not for upgrades** — every `ProxyAdmin` action needs the 2/2. Elsewhere Coinbase acts alone: the 3/12 `Base Multisig 1` owns `SystemConfig` (sequencer, gas configuration) and is Incident Responder, and the Coordinator Multisig owns `TEEProverRegistry` and `NitroEnclaveVerifier`, so it can change the TEE prover allowlist, one of the two proof arms, without the Council.",

"Who can override the Council?": "**Nobody — it administers itself.** Seats are changed by the Council Safe calling itself, so 8 of the 11 sitting members decide who joins or leaves. There is no token, DAO or veto body. The 2/2 blocks both ways: neither side can upgrade alone. Below 8 available signers upgrades stall, and there is no liveness module handing control to a fallback."

No timelock, and no Safe carries a delay module. Beryl verifier-hash update, June 2026: Council approved 22 Jun, Coinbase 23 Jun, executed 43 minutes later.",
"Emergency upgrade path": "**None** — the normal path executes as soon as both Safes sign, so there is no lower emergency threshold. The fastest lever is a pause: the 3/12 `Base Multisig 1` can pause withdrawals alone as Incident Responder, but only once per identifier, since the pause expires after 3mo 1d and it cannot pause again until the Guardian unpauses. The Guardian is the 2/2 `Base Governance Multisig` itself, which can also blacklist dispute games, set the respected game type and retire all in-flight games.",
"Exit window": "**None** — nothing separates the second signature from the upgrade taking effect, so users cannot withdraw ahead of an unwanted change. Tasks are published before signing and Base targets six hard forks a year, but neither is enforced onchain."

"tokenGovernance": {
"Governance token": "**None** — Base has no token, so no token-weighted vote enters the upgrade path. Coinbase has said it is exploring one.",
"Voting venue": "**None** — no DAO, governor contract, Snapshot space or forum vote gates an upgrade. Coordination happens in [base/contract-deployments](https://github.com/base/contract-deployments).",
"Proposal rights": "**Coinbase only** — upgrade tasks are Coinbase-authored, and no route exists for a third party to put an upgrade to the Council.",

"description": "Base decouples from the shared Optimism SuperchainConfig (`0x95703e...`) and deploys its own SuperchainConfig v2.5.0 at `0xb535ff7F118260a952CE65e7fF41B1743De8EE6c`. Compared to the previous v2.4.0, the new version adds an immutable incident responder role (Base Multisig 1) and makes the guardian immutable in the constructor. All L1 contracts (OptimismPortal2, L1StandardBridge, L1ERC721Bridge, L1CrossDomainMessenger, AnchorStateRegistry, DelayedWETH x2) now reference the new SuperchainConfig.\n\nGuardian changed from Optimism Guardian Multisig (`0x09f7150D...`) to Base Governance Multisig (`0x7bB41C3...`). All Optimism shared governance contracts removed from discovery scope (SuperchainProxyAdmin, SuperchainProxyAdminOwner, OpFoundationUpgradeSafe, OpFoundationOperationsSafe, Optimism Security Council, LivenessModule, LivenessGuard, DeputyPauseModule, SaferSafes).\n\nSystemConfig upgraded from v3.13.1 to v3.13.2 — implementation change is only a ReinitializableBase version bump from 3 to 4. The reinit sets new runtime values (guardian, superchainConfig now point to Base's own contracts). [Diff](https://disco.l2beat.com/diff/eth:0xd392c27B84b1cA776528F2704BC67B82a62132d2/eth:0x0507Aaa21c678976FCdC7e804836ACd6ebc17a44)\n\nFeeDisburser upgraded (impl `0x45969D...` → `0xDa70b4...`), removing on-chain Optimism revenue sharing (previously 2.5% gross / 15% net to OPTIMISM_WALLET). Now bridges 100% of collected fees to L1_WALLET. Revenue sharing likely moved off-chain or to a different mechanism. [Diff](https://disco.l2beat.com/diff/base:0x45969D00739d518f0Dde41920B67cE30395135A0/base:0xDa70b4cd0Cd8193f665A7D49CeFD5f79F11FCc75)\n\nPause mechanics: the Incident Responder (Base Multisig 1, 3/13) can trigger a single pause lasting up to 3 months. It cannot unpause, extend, or re-pause after expiry — only the Guardian (Base Governance Multisig, 2/2) can do that. The Guardian can extend pauses indefinitely. This prevents the operator from permanently censoring withdrawals without Security Council approval.\n\nBase Security Council threshold increased from 7/10 to 8/11 (new member added). The upgrade path changed from 3 parties (Coordinator + SC + OP Foundation) to 2 parties (Coordinator 3/6 + SC 8/11), with an effective entity-level quorum of 9/12 (75%). The Coordinator Multisig absorbed the old Base Multisig 2 members directly (same 6 EOAs) and the OP Foundation was removed as a signer on the Governance Multisig.",

"description": "'Jovian' Upgrade + Fusaka Readiness: https://gov.optimism.io/t/upgrade-17-jovian-hardfork-and-fusaka-readiness/10400\n\nStarting in Jovian, every non-deposit L2 tx gets a DA usage estimate and the block sums those up into a new resource called DA footprint. Each non-deposit tx compute daUsageEstimate using the Fjord linear model using the tx fastlzSize, and then multiply by the scalar (daFootprintGasScalar). The scalar essentially is a bytes-to-gas conversion factor, e.g. higher daFootprintGasScalar -> each estimated DA byte costs more footprint-gas -> stricter DA-per-block cap. In practice:\n- blocks can become “DA-full” before they are “gas-full” (daFootprint(block) <= gasLimit)\n- base fee now responds to DA-heavy blocks - base fee update uses gasMetered := max(gasUsed, blobGasUsed)\nand Jovian repurposes blobGasUsed to store daFootprint\n- DA-heavy transactions become pricier to include (DA-heavy blocks push gasMetered up, which pushes EIP-1559 base fee up, which feeds back into tx pricing)\n\nL1Block - setL1BlockValuesJovian() that introduces daFootprintGasScalar (400 default value)\nhttps://disco.l2beat.com/diff/base:0xFf256497D61dcd71a9e9Ff43967C13fdE1F72D12/base:0x3Ba4007f5C922FBb33C454B41ea7a1f11E83df2C\n\nAlready templatized (minimal diff):\n\nOptimismMintableERC20Factory\nhttps://disco.l2beat.com/diff/eth:0x5493f4677A186f64805fe7317D6993ba4863988F/eth:0x8ee6fB13c6c9a7e401531168E196Fbf8b05cEabB\n\nL1StandardBridge\nhttps://disco.l2beat.com/diff/eth:0xe32B192fb1DcA88fCB1C56B3ACb429e32238aDCb/eth:0x61525EaaCDdB97D9184aFc205827E6A4fd0Bf62A\n\nDisputeGameFactory\nhttps://disco.l2beat.com/diff/eth:0x33D1e8571a85a538ed3D5A4d88f46C112383439D/eth:0x74Fac1D45B98bae058F8F566201c9A81B85C7D50\n\nOptimismPortal2\nhttps://disco.l2beat.com/diff/eth:0x381E729FF983FA4BCEd820e7b922d79bF653B999/eth:0x7Cf803296662e8C72A6C1d6450572209aCF7f202\n\nL1ERC721Bridge\nhttps://disco.l2beat.com/diff/eth:0x7f1d12fB2911EB095278085f721e644C1f675696/eth:0x74f1aC50EB0BE98853805D381C884f5f9abDEcf9\n\nSystemConfig\nhttps://disco.l2beat.com/diff/eth:0x2bFE4A5Bd5A41e9d848d843ebCDFa15954e9A557/eth:0x2fA28989fc559836E9d66dFf3010C7F7f41c65ED\n\nL1CrossDomainMessenger\nhttps://disco.l2beat.com/diff/eth:0x22D12E0FAebD62d429514A65EBAe32dd316c12D6/eth:0xb686F13AfF1e427a1f993F29ab0F2E7383729FE0",

"proofSystemInfo": "## Description\n\nRISC Zero is the first zkVM proving RISC-V ISA programs. Its STARK proving system is based on a rather standard theoretical construction of [Ben-Sasson et al paper](https://eprint.iacr.org/2018/046) and [DEEP-ALI version of FRI](https://eprint.iacr.org/2019/336). The proof of zkVM execution is wrapped in Groth16 SNARK for efficient onchain verification. RISC Zero onchain verifier targets [96 bits of security](https://dev.risczero.com/api/security-model#cryptographic-security).\n\n## Proof system\n\n### RISC-V circuit\n\nRISC Zero implements a [circuit that proves RISC-V RV32IM instruction set](https://github.com/risc0/risc0/tree/main/risc0/circuit/rv32im) (see [here](https://dev.risczero.com/api/zkvm/zkvm-specification#the-zkvm-execution-model) for more details). Arithmetization of this circuit has different types of columns: control, data and accumulator. Control columns contain public data that describes the RISC-V program being executed and proven. Data and accumulator columns contain private data (accessible only to prover), data represents the running state of the processor and memory and accumulator is auxiliary data for the PLOOKUP argument.\n\n### Recursion circuit\n\nRISC Zero prover supports recursive proving of RISC-V programs using [recursion circuit](https://github.com/risc0/risc0/tree/main/risc0/circuit/recursion). This is a separate STARK circuit that is designed to efficiently generate proofs for the verification of STARK proofs, it uses the same proving system as the RISC-V circuit.\n\nBig programs are split into several segments that are executed and proven in parallel. Segment receipts (i.e. proofs of correct execution) are verified with recursion circuits and succinct receipts are produced. These succinct receipts could be recursively joined in pairs of two until a single succinct proof of the whole execution is produced. \n\n### Final wrap\n\nRISC Zero [implements a SNARK wrapping](https://github.com/risc0/risc0/tree/main/risc0/groth16) of a recursive succinct receipt into a Groth16 proof over BN254 curve for onchain verification. This Groth16 R1CS circuit uses a circuit-specific trusted setup, the ceremony was run by RISC Zero, see [below](#trusted-setups) for more details. \n\nThe final wrap circuit has a [control root](https://dev.risczero.com/terminology#control-root) public input that depends on the RISC-V and recursion circuit versions. This design allows upgrading RISC Zero proving system without changing the final wrapper and thus without running a new trusted setup ceremony.",
