op-alloy-genesis

Genesis types for Optimism.

Usage

By default, op-alloy-genesis enables both std and serde features.

If you're working in a no_std environment (like kona), disable default features like so.

[dependencies]
op-alloy-genesis = { version = "x.y.z", default-features = false, features = ["serde"] }

Rollup Config

op-alloy-genesis exports a RollupConfig, the primary genesis type for Optimism Consensus.

There are a few constant declarations for various chain's rollup configs.

use op_alloy_genesis::{OP_MAINNET_CONFIG, rollup_config_from_chain_id};

let op_mainnet_config = rollup_config_from_chain_id(10).expect("infallible");
assert_eq!(OP_MAINNET_CONFIG, op_mainnet_config);

Provenance

This is based off of alloy-genesis.
