New Phantom Update Is Coming, and Some Say It Could Backfire

Phantom has announced the upcoming launch of Phantom Chat, a new social feature planned for 2026 that aims to make on-chain interaction more seamless.

But almost immediately after the announcement, concerns surfaced over whether the feature could unintentionally widen existing attack vectors tied to wallet user interfaces.

On-chain investigator ZachXBT publicly warned that Phantom Chat could become a new entry point for asset theft if long-standing issues around address poisoning are not resolved first. His comments point to a broader UX problem that already affects many crypto wallets, not just Phantom.

Why address poisoning remains a real risk

Address poisoning works by sending users tiny “spam” transactions from addresses that visually resemble ones they’ve interacted with before. When wallets fail to properly filter or label these transactions, users may later copy the wrong address from their transaction history, unknowingly sending funds to an attacker.

According to ZachXBT, Phantom’s interface still does not adequately filter these spam transactions. He cited a recent case where a user lost 3.5 WBTC after copying a look-alike address from their recent transaction list. The first characters appeared similar enough to pass a quick visual check, leading to a costly mistake.

ZachXBT summarized the issue bluntly, calling Phantom Chat “a new method for people to get drained” unless the underlying UX problems are addressed first.

Convenience versus safety in wallet design

The discussion highlights a recurring tension in crypto wallet development: convenience versus safety. Social features like in-wallet chat may improve user engagement, but they also increase surface area for confusion, spoofing, and social engineering, especially when combined with unfiltered transaction histories.

Replies to ZachXBT’s post show that this is not an isolated incident. Multiple users reported experiencing similar mistakes in the past, often during rushed moments when they relied on recent transactions instead of carefully verifying full addresses.

What this means ahead of Phantom Chat

Phantom Chat is still planned for 2026, giving the team time to address these concerns. However, the criticism underscores that wallet UX is not just a design issue, it is a security boundary. Until spam transactions are clearly filtered or visually isolated, any feature that increases interaction with transaction histories could amplify existing risks.

For now, the episode serves as a reminder that in crypto, convenience can quietly become an attack vector if safety mechanisms do not evolve alongside new features.
