VII Finance just went live with a uniswap v4 hook on unichain that allows users to earn lending interest on top of swap fees. Here’s a detailed breakdown of how it works: Imagine you’re providing liquidity to a USDC-USDT pool on Uniswap v4 using a concentrated range. Traders swap between USDC and USDT, paying you fees for facilitating those trades. However, when no swaps occur, your capital sits idle. Given that concentrated liquidity automated market makers (CLAMMs) like Uniswap v4 are highly capital-efficient, their TVL is often a fraction of that in lending protocols, where utilization rates hover around 50%. This sparks an idea: why not lend out your USDC and USDT to a lending protocol (let’s call it “Protocol X”) to earn interest when it’s not being used for swaps? Here’s how it could work: You deposit USDC and USDT into Protocol X, receiving xUSDC and xUSDT tokens in return, which represent your principal plus accrued interest. You then provide liquidity to an xUSDC-xUSDT pool on Uniswap v4. Traders can still swap USDC for USDT by depositing USDC into Protocol X to get xUSDC, swapping xUSDC for xUSDT in the pool, and redeeming xUSDT for USDT. From the trader’s perspective, the swap is functionally identical to a standard USDC-USDT pool. As an LP, you earn both lending interest and swap fees. A win-win. But here's the Problem: As interest accrues, the value of xUSDC and xUSDT increases relative to their underlying assets. For example, after some time, 1 xUSDC might be worth 1.01 USDC, and 1 xUSDT might be worth 1.02 USDT, depending on Protocol X’s utilization rates and interest models. Since USDC and USDT interest rates differ, the relative price of xUSDC and xUSDT shifts even if the USDC-USDT spot price remains stable near 1. Without constant rebalancing of the liquidity range, the pool quotes incorrect prices, and MEV bots exploit this discrepancy, siphoning off the lending interest that should go to LPs. VII Finance’s solution: To solve this, VII Finance introduces a novel Uniswap v4 hook that works with custom wrapped tokens: VII-xUSDC and VII-xUSDT. These tokens are designed to represent only the principal of the underlying xUSDC and xUSDT, maintaining a 1:1 peg with USDC and USDT, respectively. This peg is guaranteed by smart contracts, ensuring 100% backing by the underlying assets. By creating a Uniswap v4 pool with VII-xUSDC and VII-xUSDT, LPs can use their existing concentrated liquidity strategies without worrying about interest-driven price skews. So, how do LPs capture the lending interest? When interest accrues (e.g., xUSDC increases to 1.01 USDC and xUSDT to 1.02 USDT), our system mints additional VII-xUSDC and VII-xUSDT tokens proportional to the interest accrued. (0.01 * current supply) for VII-xUSDC and (0.02 * current supply for VII-xUSDT). These newly minted tokens are then distributed to active LPs as fees via our custom Uniswap v4 yield-harvesting hook. Before every add/remove liquidity or swap operations, this hook activates and distributes the lending interest allowing the LPs to earn both lending interest and swap fees. The same Trader and LP UX: For traders, the UX remains unchanged. A helper hook automates the process: when a trader wants to swap USDC for USDT, it deposits USDC into Protocol X to mint xUSDC, wraps it into VII-xUSDC, swaps VII-xUSDC for VII-xUSDT in our pool, unwraps VII-xUSDT to xUSDT, and redeems xUSDT for USDT. For LPs, the UX is the same as well. Our helper contracts can abstract away the complexity of converting the USDC and USDT into VII-xUSDC and VII-xUSDT when adding liquidity and converting it back when removing it.
