The Challenge & Solution
Changing lending collateral manually is risky and clunky: users must withdraw assets, swap them on a DEX, and re-deposit—exposing positions to liquidation risk and requiring extra capital.
Woof Software engineered a custom 1-click smart contract engine that migrates BENQI collateral in a single atomic transaction: zero manual unwinding, zero liquidation risk, and zero extra capital needed.

Why It Matters
For Users: 1-click collateral migration (e.g., USDT → USDC) without closing active borrow positions.
For BENQI: Retains capital inside the protocol during user repositioning, boosting UX and liquidity retention.
How It Works (Under the Hood)
Flash Liquidity: Contract takes a temporary flash loan via Trader Joe.
Atomic Swap & Deposit: Redeems old collateral, swaps via 1inch, and deposits new collateral into BENQI.
1-Block Repay: Flash loan is repaid immediately. If any step fails, the transaction safely reverts.
