Component: VaultCrossChainManager

Description

The VaultCrossChainManager contract is responsible for sending and receiving cross-chain messages between the EVM and Orderly chains. It inherits from the LayerZero V2 OApp. It handles six types of cross-chain messages:

1. Liquidity Provider Deposit

2. Liquidity Provider Withdraw

3. Strategy Provider Deposit

4. Strategy Provider Withdraw

5. Distribute Assets

6. Update Claimable Amount

Invariants

1. Deposit and withdraw processing

   • When receiving deposit or withdraw messages on the Orderly chain, it calls handleOpFromVault in the Protocol Vault Ledger contract to process the deposit or withdraw operation.

2. Distribute assets

   • When receiving distribute-assets messages on the EVM chain, it calls depositToStrategy in the Protocol Vault contract to transfer assets to the DEX vault.

3. Update claimable amount

   • When receiving update-claimable-amount messages on the EVM chain, it calls updateUnClaimed in the Protocol Vault contract so providers can claim their assets.

Attack surface

• Cross-chain--message integrity

  • This contract inherits from LayerZero V2 OApp, so it only accepts messages from the LayerZero Endpoint.

  • The attacker cannot manipulate messages from either the Protocol Vault Ledger or the Protocol Vault contract.
