ALEX Protocol was exploited via a flaw in the self-listing verification logic (an on-chain limitation on Stacks).

As a result, the attacker drained several asset pools, with the breakdown of lost assets as follows:

- STX: 8,403,867.57 STX → $5,691,255.93

- sBTC: 21.85 sBTC → $2,244,751.87

- USDC/USDT: 149,850 USDC/USDT → $149,850.00

- WBTC/BTC: 2.80 WBTC → $287,369.33

Total USD Value Lost: $8,373,227.13

Using the ALEX Lab Foundation treasury, ALEX Protocol will cover 100 % of each affected user’s loss, paid in USDC.
