System Config
The system configuration is a set of configurable chain parameters defined in a contract on L1. These parameters can be changed through the system config contract, emitting events that are picked up by the rollup node derivation process. To dive deeper into the System Config, visit the OP Stack Specifications.
SystemConfig
Type
The SystemConfig
type is defined in op-alloy-genesis
.
Parameters defined in the SystemConfig
are expected to be updated
through L1 receipts, using the update_with_receipts
method.
Holocene Updates
The Holocene Hardfork introduced an update to the SystemConfig
type, adding EIP-1559 parameters to the config.
The SystemConfig
type in op-alloy-genesis
provides a method
called eip_1559_params
that returns the EIP-1559 parameters encoded as
a B64
.
