Lender Guide
Provide WETH liquidity for flash loans while keeping funds in your wallet. You control your limits and can pause or resume anytime.
1) Wrap ETH → WETH
The router works with WETH (Wrapped Ether). Use the dashboard to wrap some ETH to WETH, or use existing WETH you already hold. Your WETH stays in your wallet at all times.
2) Approve the Router
Approve the FlashBankRouter to temporarily access your WETH during flash loan execution. This is a one-time approval. The router only pulls WETH during an active loan and returns it immediately with your fee share.
3) Set Your Commitment
Choose a maximum WETH amount the router can use, or select Unlimited for hands-off participation. You can pause, resume, or change limits at any time with instant effect.
4) Earn Fees
Every time a borrower uses your WETH in a flash loan, you earn a share of the 0.02% fee. Fees are distributed proportionally among the providers whose liquidity was used.
Notes
- Your WETH never leaves your wallet — the router only has approval to pull during active loans (milliseconds).
- The protocol fee is 0.02% for borrowers; fees are shared among providers whose WETH was used.
- You can change limits, pause, or resume at any time — changes take effect immediately.
- There are no lock-up periods. Simply revoke approval or pause to stop participating.
