WBTC ReactorFusion
About WBTC ReactorFusion
WBTC ReactorFusion is an autocompounder on zkSync with BTC 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 BTC, 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 BTC 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 May 2024. Currently showing a 3.47% 24-hour APY and 3.47% across the trailing 30 days.

Frequently Asked Questions
What's the current APY for WBTC ReactorFusion?
WBTC ReactorFusion is showing a 24-hour APY of 3.47%, with a 30-day average of 3.47%. 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 BTC 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 BTC 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 $0 in TVL. 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.
