Trust Wallet introduced a built-in feature named Address Poisoning Protection to prevent asset theft via dusting or address poisoning attacks.

How address poisoning schemes operate

In a typical attack, malicious actors send tiny transfers to a target address to create misleading transaction history entries for future use.

Attackers rely on users copying recipient addresses from transaction history or recent lists without checking each character for subtle differences.

How the new protection works

The feature automatically scans a pasted or copied recipient address immediately after it appears in the wallet interface, before transaction formation.

Checks run against a maintained database of malicious addresses that Trust Wallet operates jointly with security teams at Binance and HashDit.

When a match or a suspicious lookalike pattern is detected, the application issues an instant warning to the user and prevents unverified submissions.

Supported networks and scope

At launch the protection covers 32 EVM-compatible networks, including Ethereum, BNB Smart Chain, Polygon, Arbitrum, and Optimism.

• Ethereum
• BNB Smart Chain
• Polygon
• Arbitrum
• Optimism

Timing and differentiation from contract scanners

This protection acts earlier than conventional security scanners that analyze smart contracts during confirmation, intervening before a transaction is composed.

Developers say the measure responds to recent incidents and to growing social engineering complexity across Web3, positioning the feature as a preventive control.
