📋 Next Steps

Immediate Actions

1. Decision: Choose solution approach

   • Recommended: Install OpenZeppelin (short-term)
   • Long-term: Refactor contracts (reduce dependencies)

2. Implementation: Execute chosen solution

   • Install OpenZeppelin OR
   • Refactor contracts

3. Verification: Verify all contracts compile

   • Run forge build
   • Run forge test
   • Verify deployment scripts

Long-term Strategy

1. Refactor Contracts: Remove OpenZeppelin dependencies
2. Follow Patterns: Use patterns from new WETH contracts
3. Reduce Dependencies: Minimize external dependencies
4. Improve Maintainability: Better maintainability

🎯 Conclusion

All assessment and documentation tasks are complete. The new WETH contracts (WETH10, CCIPWETH9Bridge, CCIPWETH10Bridge) are independent, compile successfully, and are ready for deployment.

The remaining 8 tasks (24%) depend on a decision regarding the solution approach for existing contracts that require OpenZeppelin. Once a decision is made, the implementation and verification tasks can proceed.

No gaps in the assessment - all tasks have been identified, documented, and are ready for execution once a decision is made.
