Trust Wallet has added real-time address poisoning protection, adding another wallet-level defense against one of crypto’s most persistent social-engineering scams.
The new feature warns users when a copied or entered recipient address appears to be a lookalike scam address, with the first rollout covering 32 EVM chains on mobile. Address poisoning as a scam in which attackers plant nearly identical wallet addresses into a user’s transaction history in the hope that the victim later copies the wrong one.
The practical value of the update is timing. Address poisoning losses usually happen before a transaction is signed, not after. The scam works by tricking users into trusting a familiar-looking address that only matches the first and last few characters of a real recipient.
A real-time warning system changes that flow by putting the risk signal exactly where the mistake happens, at the point when a user copies, pastes, or enters the destination address. That is more useful than post-transaction education because blockchain transfers are generally irreversible once sent.
Trust Wallet has long warned users not to rely on transaction history when sending funds and instead to verify the full address or use trusted saved contacts. The new protection pushes that guidance into the product itself, turning a best practice into an active pre-send check rather than leaving it entirely to user vigilance.
Address poisoning is effective because it exploits a normal wallet habit rather than a protocol flaw. Most users do not read every character of a long wallet address. They recognize a few characters at the beginning and end, assume the address is familiar, and move on.
That small convenience is exactly what attackers target. They generate spoofed addresses that visually resemble legitimate ones, send dust transactions or other low-value transfers, and wait for victims to pull the fake address from recent history. In a market built around irreversible transfers, that can be enough to turn one moment of inattention into a permanent loss.
The scam has also scaled industrially. Recent academic research on blockchain address poisoning found hundreds of millions of attack attempts across Ethereum and BNB Smart Chain over a two-year period, with millions of targeted victims and large aggregate losses. That makes wallet-side detection more than a quality-of-life improvement. It is becoming a core part of consumer crypto safety.
This update matters because the wallet interface is where most address poisoning attacks become actionable. Attackers do not need to break encryption or compromise custody if they can manipulate the user’s decision at the moment funds are sent.
That makes prevention at the wallet layer especially important. A warning system that identifies spoofed or suspiciously similar recipient addresses can stop the mistake before the signature happens. It does not eliminate the need for careful verification, but it reduces the odds that a familiar-looking fake address slips through because the user was moving too fast.
It also shows how wallet security is broadening. The industry is moving beyond basic private-key protection toward more contextual defenses, including transaction simulation, dapp risk screening, malicious-signature warnings, and now more active recipient-address checks.
Trust Wallet’s update also fits a broader pattern. Security improvements are starting to appear at multiple layers of the user journey, not only inside wallets but also in explorer and account-management tools.
That broader trend was visible yesterday when Etherscan launched a batch revoke feature for token approvals, making it easier for users to cancel multiple stale allowances at once. A separate write-up on that update is here.
Taken together, the two updates point in the same direction. Crypto security is becoming more operational and less passive, with tools that help users catch mistakes before sending funds and clean up risky permissions after interacting with dapps.
