[Fluid](https://ethdaily.io/fluid-aweth-redemption-protocol) [disclosed](https://x.com/0xfluid/status/2061124908277538827) a compromise of its off-chain Merkle rewards distribution infrastructure. According to YAM, an attacker [was able](https://x.com/yieldsandmore/status/2061100297502540145) to submit and approve fraudulent Merkle roots across Fluid's off-chain rewards distribution contracts. The attacker drained an estimated 125,000 FLUID and 51,900 GHO on May 28, 2026.

The attacker then swapped the tokens, bridged proceeds, and routed ETH into Tornado Cash. The Fluid team stated that the core protocol smart contracts are fully safe and unaffected, as the incident only pertained to a rewards distribution contract. A detailed post-mortem will be shared in the coming weeks.

Fluid most recently [extended its aWETH redemption protocol to L2](https://ethdaily.io/fluid-aweth-redemption-protocol-on-l2) following the [KelpDAO and LayerZero exploit](https://ethdaily.io/929) that froze Aave markets in April.
