Inefficient Deployment of a New WToken for Each Collateral Token
Summary
The _registerCollateralToken function deploys a new wToken contract each time a collateral token is registered. This approach is inefficient because
- Each deployment costs extra gas, increasing transaction costs.
- Contracts are immutable meaning any upgrade or modification requires deploying new instances
- Storage grows unnecessarily, increasing the blockchain state size.
Impact
Gas costs Increase significantly for each registered token
Cannot reuse logic, making upgrades and maintenance harder.
Unnecessary contract deployments make the system less efficient
