ZachXBT Flags Phantom Chat Risk as 3.5 WBTC Is Stolen
Phantom's new chat feature arrives amid warnings that address-poisoning scams — implicated in a 3.5 WBTC loss — remain active [1].
Phantom has announced a new "Phantom Chat" social feature for its Solana wallet, but the rollout has drawn security warnings after researcher ZachXBT linked a recent 3.5 WBTC theft to spam transactions that copied trusted wallet address patterns [1][3].
Security analysts characterize the incident as an "address poisoning" attack, where malicious transactions populate wallet histories with lookalike entries so users may accidentally select spoofed addresses during transfers; reports say these scams have drained millions and are surging in frequency [2][4].
Observers note the vulnerability remains unresolved ahead of Phantom Chat's launch, raising concerns that adding social and messaging features could amplify address-poisoning vectors unless wallet interfaces implement stronger protections against spoofed history entries [1][3].
Reports recommend caution and emphasize the need for UI-level mitigations to prevent address poisoning as wallet social features roll out [1][2].
