Bloom Trading Bot Users Lose Nearly $1 Million in Solana Wallet Drain

TLDR About 9,408 SOL, worth roughly $950,000 to $954,000, was taken from 48 to 49 Bloom Trading user wallets on October 26, 2026. Bloom has paused some services and says it is looking into a possible third-party compromise. The largest single loss was 1,636 SOL, valued at about $166,000. Some traders reported personal losses of up to $80,000. Bloom has promised to reimburse affected users by sending funds to new, secure wallets. Bloom generates and holds the private keys for user wallets, a custodial setup that critics say adds risk.
