OP Stack Contracts Upgrade [Mainnets]

Conduit OP Stack Mainnet would be undergoing contract upgrades (op-contracts v3.0.0 → v5.0.0).

Action required: None

No changes required even if you are running external nodes.

Possible Impact:

Pending withdrawals can be invalidated and must be proven again (no funds at risk).
New AnchorStateRegistry and DelayedWETH proxy contracts will be deployed → addresses will change. If you rely on these addresses, please let us know.
The shape of the contracts.json you download for your network from conduit dashboard/API may also change to align with latest OP Stack changes

This upgrade aligns your mainnet with the latest OP Labs contracts and paves the way for Jovian hardfork activation which is planned shortly afterwards (more details to follow).

Ps. This upgrade will not include Katana mainnet.
