The problem: Users want to buy NFTs/services but don't want to sell their ETH. They either don't buy, or they sell and create taxable events.
The solution: One-click borrowing at checkout. Users deposit ETH as collateral, borrow USDC, pay the merchant, all in one transaction.
Live demo: https://defi-loan-aggregator.vercel.app
How it works: - Merchant adds <script src="https://loanfi.xyz/widget.js"></script> to checkout - User clicks "Pay with LoanFi" - Widget shows rates from Aave/Compound - One tx: deposit collateral → borrow → pay merchant - User repays the loan over time to the pool (not to us)
Tech: Next.js, Privy, Wagmi, Base chain. Aave referral integration built in.
Looking for: - DeFi projects that want to add "Pay with LoanFi" to their checkout - Feedback on the UX from actual users - Thoughts on the business model (Aave referrals + widget fees)
