How Lending Works

40 Acres uses a peer-to-pool lending model. Lenders deposit USDC into the vault. That USDC is used to fund borrower loans. Each epoch, borrowers’ collateral rewards are collected and distributed back to lenders as yield. This is real yield sourced from DEX trading fees and bribes, not token emissions. Your return is a function of how well the underlying DEX ecosystem performs, not a protocol subsidy.

​
Depositing

  1. Navigate to the Earn dashboard
  2. Select the vault you want to deposit into (Base, Optimism, or Avalanche)
  3. Enter your USDC amount and confirm the transaction
  4. You begin earning yield immediately after your deposit is confirmed
Vault shares are ERC4626 compliant. Your position is represented by vault tokens redeemable for your pro-rata share of vault assets plus accrued yield.

​
Yield Distribution

Yield is distributed continuously over the course of each 7-day epoch, based on the previous epoch’s voting rewards. As utilization rises and falls, your yield share adjusts accordingly (with dynamic fees enabled). Current APY range: 5–20% depending on vault utilization and DEX epoch performance.

​
Withdrawing

You can request a withdrawal at any time from the Earn dashboard. Withdrawals are subject to available liquidity. The protocol maintains an 80% utilization cap, meaning at least 20% of vault funds must remain available for withdrawals. If a vault is fully utilized, you will need to wait for repayments to free up liquidity before withdrawing. The dashboard shows current available liquidity in real time. Secondary markets are also available in the event you can’t wait for liquidity to return. Powered by KyberSwap Limit Orders. → Sell your vsAERO_USDC here
