Earn yield on MON and USDC: WOOFi Earn is live on Monad

TL;DR: WOOFi Earn vaults are live on Monad. You can deposit MON or USDC and earn yield paid in the same token, with nothing to claim. At launch the APY is about 8% a year on MON and about 6% on USDC. The vaults use the WOOFi Earn contracts that have been in production since 2022. Every deposit also deepens WOOFi's liquidity on Monad, which means better prices for Monad traders.

Hello, Monad. Most tokens in a wallet do one thing: they sit there. Put yours to work with WOOFi Earn.

What are WOOFi Earn vaults?

A WOOFi Earn vault is a single-sided vault: a smart contract that takes one token, lends it to WOOFi's market maker, and pays the interest back to you in the same token. Deposit MON and your MON balance grows. Deposit USDC and your USDC balance grows.

The yield is borrowing interest, not a token incentive or a rewards programme. It compounds automatically, so there is nothing to claim or restake.

Where does the yield come from?

WOOFi runs a PropAMM, an onchain market maker that quotes prices from live market data instead of from the balance of a pool. To fill a swap from USDC into MON, it needs MON on hand. The Earn vaults are where that inventory comes from.

You deposit MON or USDC into the vault from your own wallet.
WOOFi borrows. The WOOFi liquidity pool is the only address allowed to borrow from a vault.
Interest flows back. The pool pays borrowing interest to the vault, so each share of the vault is worth more tokens over time.

What APY can you earn on MON and USDC?

At launch, the Earn page shows 8% a year on MON and about 6% on USDC (woofi.com/earn, 13 November 2026). The rate is not fixed. It is set by a formula and moves with deposits and trading demand: as deposits grow, the yield comes down slightly, and as trading volume grows, it goes up. Over time, WOOFi vault yields tend to settle between 4% and 9% a year. The live rate for each vault is always on the Earn page.

Why deposit on WOOFi?

One token in, the same token out

You deposit a single asset and stay fully in it. There is no second token to pair and no price range to manage.

No impermanent loss for depositors

On most DEXs, liquidity providers carry impermanent loss. In Earn vaults that risk sits with WOOFi's market maker, not with you.

Your deposit stays inside WOOFi

Earn vaults do not place your tokens in third-party protocols. Only WOOFi's own liquidity pool can borrow from a vault.

Battle-tested since 2022

WOOFi Earn is not new code. The Earn vault contracts have been in production since 2022 and have held tens of millions of dollars in deposits, peaking above $33 million in December 2024 (DefiLlama). They have been audited by multiple firms including PeckShield and Zellic. The Monad vaults use the same vault design that runs on WOOFi's other networks.

Deeper liquidity means better trades on Monad

The more assets the vaults hold, the more inventory WOOFi has to quote with. That means Monad users get better execution on their swaps, at any size, whenever they want it.

How to earn yield on MON and USDC

Open woofi.com/earn, connect your wallet, and switch to Monad. Keep a small amount of MON for gas.
Choose the MON vault or the USDC vault.
Enter an amount and deposit. For USDC, your wallet asks you to approve the token first. Your position starts earning once the transaction confirms.

How do you withdraw?

You can request a withdrawal at any time. Each vault settles weekly at 0:00 UTC on Monday, and requests made before that are ready to withdraw on Tuesday. Each vault also sets aside 10% of its assets for instant withdrawals, which carry a 0.3% fee.

FAQ
