Alephium's June 3 official on-chain report describes the May 30, 2026 Alephium Bridge exploit. The attacker used a fake-event contract to feed false data into the bridge path, drained assets from Ethereum and BSC in about 64 seconds, minted 13,757,076.37 unbacked wALPH, routed proceeds through swaps, deBridge, and Tornado Cash, and left 500,000 wALPH outside the immediate recovery window.
