Configuration

When deploying or upgrading the OPSuccinctL2OutputOracle contract, you will need to set the configuration parameters in your .env file.

Required Parameters

When deploying or upgrading the OPSuccinctL2OutputOracle contract, the following parameters are required to be set in your .env file:

Parameter	Description
`L1_RPC`	L1 Archive Node.
`L1_BEACON_RPC`	L1 Consensus (Beacon) Node.
`L2_RPC`	L2 Execution Node (`op-geth`).
`L2_NODE_RPC`	L2 Rollup Node (`op-node`).
`PRIVATE_KEY`	Private key for the account that will be deploying the contract.
`ETHERSCAN_API_KEY`	Etherscan API key used for verifying the contract (optional).

Optional Advanced Parameters

You can configure additional parameters when deploying or upgrading the OPSuccinctL2OutputOracle contract in your .env file.

Parameter	Description
`VERIFIER_ADDRESS`	Default: Succinct's official Groth16 VerifierGateway. Address of the `ISP1Verifier` contract used to verify proofs. For mock proofs, this is the address of the `SP1MockVerifier` contract.
`STARTING_BLOCK_NUMBER`	Default: The finalized block number on L2. The block number to initialize the contract from. OP Succinct will start proving state roots from this block number.
`SUBMISSION_INTERVAL`	Default: `1000`. The minimum interval in L2 blocks at which checkpoints must be submitted. An aggregation proof can be posted for any range larger than this interval.
`FINALIZATION_PERIOD_SECS`	Default: `3600` (1 hour). The time period (in seconds) after which a proposed output becomes finalized and withdrawals can be processed.
`PROPOSER`	Default: The address of the account associated with `PRIVATE_KEY`. If `PRIVATE_KEY` is not set, `address(0)`. An Ethereum address authorized to submit proofs. Set to `address(0)` to allow permissionless submissions. Note: Use `addProposer` and `removeProposer` functions to update the list of approved proposers.
`CHALLENGER`	Default: The address of the account associated with `PRIVATE_KEY`. If `PRIVATE_KEY` is not set, `address(0)`. Ethereum address authorized to dispute proofs. Set to `address(0)` for no challenging.
`OWNER`	Default: The address of the account associated with `PRIVATE_KEY`. If `PRIVATE_KEY` is not set, `address(0)`. Ethereum address authorized to update the `aggregationVkey`, `rangeVkeyCommitment`, `verifier`, and `rollupConfigHash` parameters. Can also transfer ownership of the contract and update the approved proposers. In a production setting, set to the governance smart contract or multi-sig of the chain.
