Veilend

Keep the yield. Unlock instant liquidity.

Borrow against your Uniswap v4 LP — without unwinding it. Your credit profile is scored confidentially in a Chainlink CRE hardware enclave, unlocking higher LTV and lower APR without exposing your financial history on-chain.

The chain only receives verified terms. The position keeps accruing fees and is automatically returned upon repayment.

01What Veilend does
01

Borrow without unwinding LP inventory

Your Uniswap v4 LP position serves as locked collateral. Keep earning active swap fee yield and avoid taxable unwinding or slippage.

02

Confidential risk scoring in TEE

Credit inputs are computed privately inside Chainlink CRE hardware enclaves. Proven track records unlock higher LTV and lower APR without leaking history on-chain.

03

Autonomous v4 hook collateral protection

Enforced at the pool level by CollateralLockHook. Any liquidity reduction is programmatically reverted on-chain while the loan remains active.

02How it works
01

Lock the LP NFT

Approve and transfer your demo pool LP NFT into the LendingVault. Your ownership is registered on-chain while collateral is safely held.

02

Private CRE evaluation

A trusted relayer triggers a Chainlink CRE confidential workflow (handlerInTee), generating verifiable terms (LTV, APR, expiry) within the enclave.

03

Automatic vdUSD disbursement

The vault values collateral on-chain and automatically transfers loan principal in vdUSD directly to your wallet upon report submission.

04

Repay or liquidate

Repay principal plus flat interest before the deadline to automatically unlock and reclaim your NFT. If defaulted, anyone can liquidate.
