The Orderly Cross-Chain Relay V2 is an OApp based on LayerZero V2, and used to connect Vault chains (Arbitrum, OP, Base, Ethereum, etc.) to the Ledger chain (Orderly L2).
To migrate from the previous version, we need to:
- Deploy the new CrossChainRelayV2 contract on both Ledger and Vault chains.
- Upgrade the CCManager contracts on both Ledger and Vault chains.
- Set Cross-Chain option on the CCManager contracts to enable the Relay V2.
- Relay message through the new CrossChainRelayV2 contract.
The following diagram shows the architecture based on the new relay:
+---------+ LzV1 +---------+
+------+CCRelayV1+-----------+CCRelayV1+-----+
| +---------+ +---------+ |
| |
| |
+----+----+ +----+----+
+-------+ | Vault | | Ledger | +--------+
| Vault +----+CCManager| |CCManager+-----+ Ledger |
+-------+ +----+----+ +----+----+ +--------+
| |
| |
| +---------+ +---------+ |
+------+CCRelayV2+-----------+CCRelayV2+-----+
+---------+ LzV2 +---------+
Note: To backward compatible for the inflight messages through the relay V1, we need to keep the CCManager contracts callable by both relay V1 and V2 for a while. Once the inflight messages are executed, we can disable the CCManager contracts callable by the relay V1.
To keep the Relay V2 contracts same address on all chains, we need to deploy the contracts via a factory contract using Creat3 library from solady.
The factory contract 0x63B5af2724018347a1747A504e45F4e4c5AD0d04 is deployed via Seaport contract 0x7A0D94F55792C434d74a40883C6ed8545E406D12
