Ongoing Resupply Fi Hack: What We Know So Far

June 26, 2025

2 min read

On June 26, 2025, speculation began circulating within the DeFi community about a potential exploit targeting ResupplyFi, a decentralized stablecoin protocol integrated with Curve and Frax. At the time of writing, ResupplyFi has not released an official statement, and no confirmations have been made regarding a hack or exploit.

Still, the lack of communication has raised concerns—especially as users monitor on-chain activity and ResupplyFi’s silence across X and its governance forum.

What is ResupplyFi?

ResupplyFi allows users to mint reUSD by supplying crvUSD or frxUSD to Curve Lend or Fraxlend. It combines traditional DeFi lending mechanics with a native insurance pool designed to mitigate unforeseen protocol risks.

What Should You Do?

Here’s what we recommend until more details are confirmed:

1. Avoid new interactions with ResupplyFi smart contracts

Do not deposit, borrow, or interact with reUSD vaults until the team issues a formal update.

2. Withdraw funds if feasible

If you currently have funds deposited and are able to safely withdraw (gas-efficiently), you may consider exiting your positions as a precaution.

3. Monitor ResupplyFi’s official channels

Keep a close watch on:

4. Watch for impersonators

Scammers often capitalize on uncertainty. Do not trust messages or announcements unless they come directly from ResupplyFi’s official channels.

5. Stay informed via on-chain monitoring

Use DeFi analytics tools (like DeBank, Etherscan, and DefiLlama) to track your positions and any irregular movements in ResupplyFi contracts.

Ongoing speculation in Discord and DeFi forums

Until more information becomes available, it is prudent to act with caution.
