Phantom Chat Raises Security Concerns Ahead of Launch

• Phantom announces “Phantom Chat” for 2026 with social features.
• ZachXBT warns it could aid asset theft via address poisoning.
• A user reportedly lost 3.5 WBTC due to this ongoing issue.

Phantom, the popular Solana-based wallet, has announced a new feature called Phantom Chat, expected to launch in 2026. Marketed as a step toward social integration in Web3, the chat function is meant to allow users to communicate directly within the wallet environment.

While this feature aims to improve user interaction and coordination, it has raised red flags among security-conscious voices in the crypto space. Chief among them is the prominent on-chain investigator ZachXBT, who shared serious concerns about how the chat feature could open the door to scams and wallet attacks.

ZachXBT Warns of Address Poisoning Exploits

ZachXBT specifically highlighted the danger of address poisoning, a tactic where attackers send users spam transactions with wallet addresses that closely resemble their real contacts. If users mistakenly copy and paste one of these fraudulent addresses from their transaction history, they may unwittingly send assets to scammers.

Despite repeated warnings, Phantom has yet to implement robust filtering or tagging mechanisms to reduce the visibility of these spoofed transactions. In his latest alert, ZachXBT disclosed that a user recently lost 3.5 Wrapped Bitcoin (WBTC)—equivalent to over $150,000—because of this very exploit.

The concern now is that a chat feature, if not properly secured, could become another vector for scammers to deliver malicious addresses or links, putting users’ funds further at risk.

User Safety Should Be a Top Priority

With Phantom Chat on the horizon, many in the community are urging the wallet provider to address these known issues before expanding its functionality. Adding social elements is an exciting development for many Web3 users, but not at the cost of compromising wallet security.

For now, users are advised to double-check any wallet addresses they interact with and to avoid copying addresses from unverified transaction logs. Until Phantom takes active steps to prevent address poisoning, the risk of such scams remains high.
