Incident Overview
Cross-chain bridge protocol Across was attacked on its Solana deployment on July 17, 2026. The attacker exploited a gap in Solana’s event system to spoof deposit signals, tricking relayers into paying out on fake deposits. User funds remained completely safe with zero losses; all transactions were completed or fully refunded. Losses were contained to the Risk Labs-operated relayer. The team paused Solana deposits and restored operations the next day, with a full post-mortem planned.
