What is Earn
A plain-English explainer of Quicknode Earn.
Quicknode Earn is a non-custodial USDC yield optimizer. It watches approved Morpho vaults on Ethereum, Optimism, Unichain, Polygon, Monad, Base, and Arbitrum, and moves your capital toward the highest eligible APY.
- You deposit USDC through the Earn contract, which deposits it into one or more Morpho vaults. The vault shares are minted to your own wallet. Earn holds nothing between transactions.
- Because the shares are yours, you can redeem them directly on Morpho at any time, with or without Earn. Earn does not see that redemption, so close a live strategy through Earn. See Your shares.
- Earn checks the vaults every five minutes and moves your capital when a better vault clears the thresholds you set. On a cross-chain move the USDC is briefly in transit through Circle's CCTP. See Rebalancing.
- Earn's fee is the gas cost of each move times a per-chain factor, taken in vault shares. Never a cut of your yield. A covered strategy also pays OpenCover's 1.05% per year premium. See Fees and gas.
- Close anytime. No lockup, no token. Only your wallet can close a strategy. On a standard strategy, add or remove capital with Increase and Reduce. See Increase and Reduce.
Why Earn exists
Morpho hosts a large set of USDC vaults, each curated by a different team. APY changes with every deposit and withdrawal, so the best vault moves constantly. Tracking it by hand means watching dashboards and paying gas on every switch. Earn does the watching and the moving. You set the Rebalance gap (how much better a vault must be) and the confirmation window (how long it must stay better). See Creating a strategy.
Earn also exits a vault on the next check, at any APY, when you hide it, when its size falls below your Auto-exit vault size, or when its withdrawable liquidity falls below your Minimum withdrawable liquidity. See Forced exits.
You can change most settings later from the strategy page's Manage tab. The chain set and the vault count are fixed once the strategy is funded. See What you can change later.
What "non-custodial" means here
Your USDC passes through the Earn contract only inside a single transaction, on its way into or out of a Morpho vault. A cross-chain move is the exception: the USDC is burned on the source chain, travels through Circle's CCTP, and is deposited on the destination chain in a second transaction. See Cross-chain bridging. The vault mints its shares to your wallet, not to Earn.
The per-vault approval you grant lets the contract move those shares out of that vault: into another approved vault on a rebalance or a forced exit, or out to USDC in your wallet on a Reduce or a close. The same allowance collects the rebalance fee in shares. See Approvals and signatures.
Earn cannot see a redemption you make on Morpho yourself, so close a live strategy through Earn. See Your shares.
What Earn is not
- Not a fund: Earn pools nothing. Each position is vault shares in your own wallet.
- Not an asset manager: Auto-Pilot follows the settings you chose, within Earn's approved vault set. No one picks your vaults by hand.
- Not a token: No Earn token, no governance, no airdrop.
- Not multi-asset: USDC only.
Does USDC earn interest on its own?
No. A Morpho vault lends its USDC to borrowers who pay interest, so each vault share is worth more USDC over time. Earn does not pay the yield. It puts your USDC in the vaults with the highest share-price APY it is allowed to use. APY is variable. See Vaults.
