Variable Description

Attestation Node Config

The config.toml file in the repository contains various fields that should be configured in order to run various CLI commands.

• EthereumRPCURL: Ethereum mainnet RPC endpoint for mainnet, and Holesky RPC endpoint for testnet.

• L1RPCEndpoint: Ethereum mainnet RPC endpoint for both mainnet and Holesky testnet.

• BeaconURL: Beacon mainnet RPC endpoint for both mainnet and Holesky testnet.

• L2RPCEndpoint: Rollup (Optimism or Base or Arbitrum) chain's mainnet RPC endpoint for both mainnet and Holesky testnet.

• BLSCurve: Currently, we only support BN254 curve.

• ConcurrentFetchers: This parameter can be used to control the number of parallel fetchers that are responsible to fetch a block. Default value is 8.

• SignerServerURL: This is the gRPC server URL for signer for secure key management.

• OperatorAddress: EigenLayer operator address

• OperatorKeyAccountID: Account ID provided for storing EigenLayer operator ECDSA key in the signer

• SignerKeyAccountID: Account ID provided for storing Lagrange specific ECDSA key in the signer

• BLSKeyAccountID: Account ID provided for storing BLS (BN254) key in the signer

• MetricsServiceName = The service name used for the metrics. Default is lagrange-node.

• PrometheusRetentionTime = Retention time for Prometheus metrics data. Default is 60s.

• MetricsServerPort: The port on which Prometheus metrics of the attestation node docker container are exposed.

• HostBindingPort: The port to bind the MetricsServerPort with the host machine.

• CACertPath: The path of self signed certificate for the certificate authority (CA) to enable TLS for gRPC communication of the attestation node.

• NodeKeyPath: A new RSA private key for server

• NodeCertPath: A certificate signing request (CSR) for the server

• OperatorKeystorePath = EigenLayer operator keystore file path (Deprecated from v1.1.x of CLI)

• OperatorKeystorePasswordPath = EigenLayer operator keystore password file path (Deprecated from v1.1.x of CLI)

• SignerECDSAKeystorePath = ECDSA signer keystore file path (Deprecated from v1.1.x of CLI)

• SignerECDSAKeystorePasswordPath = ECDSA signer keystore password file path (Deprecated from v1.1.x of CLI)

• BLSKeystorePath = BLS keystore file path (Deprecated from v1.1.x of CLI)

• BLSKeystorePasswordPath = BLS keystore password file path (Deprecated from v1.1.x of CLI)

Signer Config

The config_signer.toml file in the repository contains various fields that should be configured in order to run the signer.

• AccountID: Account ID for setting up signer for your keys. The operator can choose the account id of their choice.

• KeyType: BN254 or ECDSA

• PrivateKeyPath: File path for the ECDSA or BLS private key with extension .key

• PasswordKeyPath: Password file for the private key
