USDC ReactorFusion
About USDC ReactorFusion
USDC ReactorFusion is an autocompounder on zkSync 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.
Rewards earned by the strategy (ZK) are periodically converted into USDC and added back to the vault. 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 February 2025. Currently indexed at $594 TVL across 2 holders, with a 0.65% 24-hour APY and 13.44% across the trailing 30 days.

Strategy stability
Based on APY volatility over the last 30 days. Higher scores indicate steadier yields.
Insufficient APY history to score stability for this strategy yet. At least 5 daily observations in the last 30 days are required.
This strategy currently holds $594, 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.
Long-term performance
- Share price has compounded at an annualized rate of 12.42% over 350 days, growing from 1.0000 to 1.1188. This represents a gain of ~0.119 USDC per 1 USDC supplied at launch.
- TVL experienced a 99% drawdown from its $96K peak, bottoming at $560 over 148 days. It currently stands at $594, 1% of the peak value.

Frequently Asked Questions
What's the current APY for USDC ReactorFusion?
USDC ReactorFusion is showing a 24-hour APY of 0.65%, with a 30-day average of 13.44%. 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 periodically claims any rewards that accrue. Those rewards (ZK) are then converted into more USDC and added back to the vault, increasing the value of each holder's share. The process repeats automatically; holders are not required to claim, swap, 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 a combination of interest paid by the underlying market and reward emissions in ZK, which the strategy claims and converts back into USDC on a recurring basis. The rate moves with the underlying venue's utilisation and incentive schedule.
How stable has the APY been?
There isn't yet enough 30-day APY history to score stability for this vault. The Strategy stability section above will populate once a meaningful window of records is available.
How much is currently in the vault?
The vault currently holds $594 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.
