USDC Prime
About USDC Prime
USDC Prime is an autocompounder on Ethereum with USDC as its underlying token, in which the yield is distributed. It earns yield from its underlying lending venue and automatically converts any claimed rewards into more USDC, removing the manual claim and conversion steps a user would otherwise need to perform on their own.
Yield earned by the strategy is added back to the vault on a recurring basis. Autocompounding events run when economically feasible, anywhere from hourly to several days apart, with gas costs socialised across all holders rather than borne by each user individually.
Live since May 2025. Currently indexed at $52 TVL across 2 holders, with a 2.23% 24-hour APY and 2.04% across the trailing 30 days.

Strategy stability
Based on APY volatility over the last 30 days. Higher scores indicate steadier yields.
USDCThis strategy currently holds $52, below our $50K liquidity mark. Thin liquidity can mean higher slippage on entry and exit, and the headline yield can be skewed by a small number of holders.

Frequently Asked Questions
What's the current APY for USDC Prime?
USDC Prime is showing a 24-hour APY of 2.23%, with a 30-day average of 2.04%. Rates are variable and move with market conditions, liquidity, and the underlying protocol's incentives. The figures reflect the realised yield over the trailing window; they are not a forward guarantee.
How does the autocompounding work?
The strategy holds positions in its underlying lending venue and the yield that accrues is added back to the vault on a recurring basis, increasing the value of each holder's share. The process repeats automatically; holders are not required to claim or add anything back themselves. Autocompounding events run when economically feasible, anywhere from hourly to several days apart, with gas costs socialised across all holders.
Can I withdraw at any time?
There are no withdrawal periods or lockups. If the underlying strategy holds enough liquidity to satisfy the request, exits are instant. During periods of liquidity stress in the underlying venue, withdrawal capacity can be limited until liquidity returns. See the risk page for details on how this works.
Where does the yield come from?
Yield is sourced from its underlying lending venue. The income stream is interest paid by the underlying market, added back to the vault on a recurring basis. The rate moves with the underlying venue's utilisation.
How stable has the APY been?
Over the last 30 days, this vault's APY has ranged from 1.79% to 2.29%, averaging 2.04%, with measured volatility of ±0.13%. The Strategy stability section above shows where this falls on the scale from very volatile to very consistent.
How much is currently in the vault?
The vault currently holds $52 in TVL across 2 holders. The Historical statistics section above shows how this compares to the vault's 30-day range and lifetime peak.
What are the risks?
Like any onchain yield strategy, this vault is exposed to smart contract risk in both the Harvest contracts and its underlying lending venue, market risk in the underlying venue it routes to, and protocol-specific risks of the assets it interacts with. Harvest's core vault infrastructure was audited by Halborn in January 2025. Audits reduce but do not eliminate risk.
