Bitquery Ties 9,408 SOL Loss to 48 Bloom Bot Wallets

Bitquery's reconstruction found that 48 wallets tied to Solana trading bot service Bloom lost 9,408 SOL in transfers signed with the wallets' own private keys, according to CryptoSlate. The outlet reports the drains took place on Oct. 26, with each transfer authorized only by the affected wallet's key and no second signer or token approval involved.

Bloom initially denied that private keys were exposed, CryptoSlate reports, then later on the same day said all nine affected users had been fully refunded, citing a combined 9,408 SOL across nine transactions. Bitquery found that 24 of the 48 wallets had not paid a Bloom trading fee during the prior month, while five others had last paid a fee sometime between January and May 2025, a pattern the firm has not explained.

CryptoSlate also describes a separate incident involving Bloom competitor TradeWiz, which Bitquery dates to Sept. 30, when 20,793 wallets were drained of SOL. Fee-paying bot trades stopped 41 minutes into that sweep, but Bitquery reports a bot captured 73% of the SOL taken in the main sweep afterward. It remains unconfirmed whether the Bloom and TradeWiz incidents share a common cause, whether Bloom's withdrawal lock was bypassed or worked as designed, and who carried out either drain.
