[feat. request]: Integrate x48's ETH Allow List for frontend

[mitche50]

Summary (Required)

To prevent API poisoning, yearn created a contract that verifies data against on chain data to ensure the contracts the frontend is interacting with are approved contracts.

To implement this we'd need to:

• Register badger.com on DNSSEC via ENS
• Deploy Integration contract that can validate vaults
• Deploy allowlist contract and add conditions like this
• Implement calls into frontend like yearn
