Admin roles
Challenger
This is a testnet role that is authorized to call deleteL2Outputs() to remove a state commitment. This is temporary and for emergency purposes only. On mainnet, this role will not exist, as state roots will not be reset.
System Config Owner
This is the address authorized to change the settings in the SystemConfig contract. These settings are:
The blocks signer: L2 blocks propagated among Zircuit nodes via peer-to-peer communication must be signed by this wallet to be considered valid.
The batcher hash: identifier for the batcher operator.
The gas config: overhead and scalar values used to determine the L1 costs.
The gas limit: the maximum amount of gas allowed in every L2 block.
The resource config: the configuration for the EIP-1559 based curve for the deposit gas market.
L1 ProxyAdmin Owner
This is the owner of the ProxyAdmin contract deployed on the L1 that controls most of the L1 contracts and can upgrade them if necessary. The ProxyAdmin contract is an auxiliary contract meant to be assigned as the admin of an ERC1967 Proxy, based on the OpenZeppelin implementation.
L2 ProxyAdmin Owner
This is the owner of the ProxyAdmin contract deployed on the L2 that controls most of the L2 contracts and can upgrade them if necessary. The ProxyAdmin contract is an auxiliary contract meant to be assigned as the admin of an ERC1967 Proxy, based on the OpenZeppelin implementation.
Emergency roles
