Alephium bridge exploit — team offering 10% white hat bounty for return of 90% of drained assets within 72 hours.
Security & Exploits ·
Alephium's team posted an onchain message on Ethereum mainnet offering a white hat bounty arrangement following a bridge exploit. The proposal requests return of 90% of drained assets to a specified address within 72 hours, during which time the responsible party may retain 10% as compensation for disclosure. The team indicated it would treat the incident as resolved and provide public acknowledgment of cooperation upon receipt of the recovered funds, and invited contact via a dedicated email address for further discussion.
The message was broadcast as a transaction on the Ethereum blockchain, making the offer publicly visible and timestamped. This approach bypasses traditional incident response channels and signals the team's willingness to negotiate rather than pursue legal or technical remedies exclusively. The 72-hour window and specific asset recovery target establish concrete terms for what Alephium considers acceptable resolution.
It remains unclear whether the exploit was initiated by a single actor or group, the precise mechanics of the bridge vulnerability, or the total value of assets involved. No public acknowledgment of asset return or further communication has been reported as of the onchain message.
