SecondFi to Gradually Shut Down Wallet Services Following $2.6 Million ADA Theft
2026-07-22 09:51
Odaily Planet Daily News: Cardano ecosystem wallet SecondFi stated that due to a cryptographic flaw in its wallet software, approximately 16.1 million ADA tokens (worth about $2.6 million) were stolen. The platform will gradually shut down the SecondFi and Yoroi wallet services. This incident affected 374 wallets.
SecondFi stated that an independent investigation by blockchain intelligence agency Groom Lake identified the attacker as a sophisticated external actor and found indicators potentially linked to North Korea's Lazarus Group, though attribution has not yet been confirmed.
SecondFi is developing a recovery tool based on zero-knowledge proofs to help affected users recover assets while limiting the information that needs to be shared. The tool is still being tested and will undergo a third-party audit before its planned release in August.
SecondFi is also preparing a wallet export function to allow users to migrate their assets to other services. The platform has not announced a direct compensation plan, nor has it stated whether it will use its own funds to compensate users.
