Trust Wallet has introduced address-poisoning protection, adding a new screening feature designed to help users avoid sending cryptocurrency to scam wallets that mimic legitimate addresses.
The noncustodial wallet provider said Tuesday that the new feature will automatically run a destination address check against a database of known scam and lookalike addresses to prevent malicious transactions. The rollout initially covers 32 Ethereum Virtual Machine-compatible blockchains, including Ethereum, BNB Smart Chain, Polygon, Optimism, Arbitrum, Avalanche and Base.
Trust Wallet called address poisoning attacks one of the “fastest-growing threats in crypto,” and claimed there have been over 225 million attacks and $500 million in confirmed losses to date.
Address poisoning is a form of phishing in which scammers trick victims into sending crypto to illicit wallets by first sending them small transactions, hoping that unsuspecting investors copy and paste the attacker’s address from their history.
Address poisoning losses keep rising
Address poisoning attacks recently cost two investors $62 million in cryptocurrency. One of the victims lost $50 million in USDt (USDT) in December 2025, prompting industry leaders to call on wallets to implement better security measures.

“All wallets should simply check if a receiving address is a poison address,’ and block the user. This is a blockchain query,” former Binance CEO Changpeng Zhao wrote in a Binance Square blog post on Dec. 24, 2025, adding that wallets shouldn’t display similar spam transactions in the first place.
Beyond spam transaction filtering, cryptocurrency investors need to stop copying wallet addresses from their transaction history, security firm Hacken’s Extractor team recently told Cointelegraph.
Other wallets that offer preemptive transaction filtering tools against malicious transactions include the Rabby Wallet, Zengo Wallet and Phantom Wallet.

Trust Wallet’s Chrome browser extension was compromised on Dec. 24, 2025, resulting in around $7 million in losses for users. Trust Wallet released a new version of its wallet, which removed the malicious code, and said that user losses will be covered.
