|
### CCIPWETH9Bridge & CCIPWETH10Bridge
|
|
|
|
|
|
|
|
|
|
|
|
**Ownership Model**: Admin-based
|
|
|
|
|
|
**Admin Function**: `admin()` returns `address`
|
|
|
|
|
|
**Initial Admin**: Set to `msg.sender` (deployer) in constructor
|
|
|
|
|
|
**Admin Capabilities**:
|
|
|
|
|
|
- Add/remove destination chains
|
|
|
|
|
|
- Update destination chain configurations
|
|
|
|
|
|
- Change fee token address
|
|
|
|
|
|
- Transfer admin to new address
|
|
|
|
|
|
|
|
|
|
|
|
**Verification**: ✅ All bridge contracts have deployer as admin
|
|
|
|
|
|
|
|
|
|
|
|
### WETH9 & WETH10
|
|
|
|
|
|
|
|
|
|
|
|
**Ownership Model**: None
|
|
|
|
|
|
**Reason**: Standard ERC20 tokens without ownership
|
|
|
|
|
|
**Design**: Immutable contracts (no admin functions)
|
|
|
|
|
|
**Verification**: ℹ️ No ownership to verify (by design)
|
|
|
|

## 🔍 Verification Method
|
|
|
|
|
|
|
|
|
|
|
|
Ownership was verified using:
|
|
|
|
|
|
1. **Script**: `scripts/deployment/verify-contract-ownership.sh`
|
|
|
|
|
|
2. **Method**: Direct contract calls to `admin()` function
|
|
|
|
|
|
3. **Comparison**: Admin address vs deployer address
|
|
|
|
|
|
4. **Result**: All bridge contracts verified as owned by deployer
|

|
|
|
2. **Token Immutability**: WETH9/WETH10 are immutable (no ownership)
|
|
|
|
|
|
3. **Admin Transfer**: Admin can be transferred if needed
|
|
|
|
|
|
4. **Multi-sig Consideration**: Consider transferring admin to multi-sig for production
