The protocol has suffered two major security exploits: a $4.3 million hack in May 2024 attributed to North Korea's Lazarus Group via a private key compromise of its XLink bridge, and an $8.3 million exploit in June 2025 caused by a smart contract access control vulnerability. In both cases, ALEX Lab Foundation pledged full user reimbursement, though partial recovery of 2024 stolen funds remained ongoing as of mid-2025, and the native ALEX token has declined approximately 99.9% from its all-time high.","timeline":[{"date":"2021-11-15","event":"ALEX raises $5.8 million in funding round led by White Star Capital","source":""},{"date":"2022-01-17","event":"ALEX launches mainnet on the Stacks blockchain","source":""},{"date":"2024-05-14","event":"XLink bridge private key compromised via alleged phishing attack; CertiK detects suspicious transaction","source":""},{"date":"2024-05-15","event":"ALEX Lab confirms $4.3 million exploit; offers 10% bounty for return of 90% of stolen funds; files Singapore Police report","source":""},{"date":"2024-05-18","event":"10% bounty deadline passes; ALEX Lab reports $3.9 million frozen at centralized exchanges","source":""},{"date":"2024-06-25","event":"ALEX Lab attributes May 2024 exploit to North Korea's Lazarus Group, citing ZachXBT's on-chain forensic investigation","source":""},{"date":"2025-06-06","event":"Second major exploit: $8.3 million drained via smart contract access control vulnerability in self-listing logic; ALEX token drops ~45%","source":""},{"date":"2025-06-17","event":"ALEX Lab Foundation announces completion of Treasury Grant Program; claims 100% USDC reimbursement to all affected users","source":""},{"date":"2025-07-01","event":"Farming resumed on ALEX protocol following security review","source":""}]},"v":1}
