How to include DepositContract address in the chainspec?

[debjit-bw]

In most places I see the DepositContract address is hardcoded. Is there a field name in chainspec that can set the address, block, topic in the ChainSpec? I tried depositContract or deposit_contract, none of them seem to work.

there is, the from genesis impl does this:

reth/crates/chainspec/src/spec.rs

Lines 650 to 653 in f034bf2

	let deposit_contract = genesis.config.deposit_contract_address.map(|address| {
	DepositContract { address, block: 0, topic: MAINNET_DEPOSIT_CONTRACT.topic }
	});

and initializes the field on chainspec:

reth/crates/chainspec/src/spec.rs

Line 660 in f034bf2

deposit_contract,

or for statics:

reth/crates/chainspec/src/spec.rs

Lines 43 to 48 in f034bf2

	deposit_contract: Some(DepositContract::new(
	MAINNET_DEPOSIT_CONTRACT_ADDRESS,
	11052984,
	b256!("649bbc62d0e31342afea4e5cd82d4049e7e1ee912fc0889aa790803be39038c5"),
	)),
