The lost assets include 8.4 million STX (~ $5.69 million), 21.85 sBTC (~ $2.24 million), 149,000 USDC/USDT, and 2.8 WBTC (~ $287,000).

The compensation process will be notified to affected wallets by June 8, and users need to submit claims by June 10, and the compensation will be completed within 7 working days after verification.
