Security has long been one of the biggest topics in cryptocurrency. Alongside technological advancement, fraud targeting less experienced investors has grown rapidly. Popular crypto wallet Trust Wallet has now announced a new security feature designed to help users avoid one of the fastest-growing types of fraud.
The new feature focuses on so-called “address poisoning,” a scam in which attackers mimic cryptocurrency wallet addresses and attempt to trick users into accidentally sending their crypto to them.

Wallet to Check Recipient Addresses
Trust Wallet now automatically checks the address to which a user wants to send crypto. The system compares it against a database of known fraudulent or suspicious addresses.
If the app detects that an address resembles one of the fraudulent wallets or has previously appeared in the database, it can warn the user before the transaction is sent.
This is important primarily because cryptocurrency transactions are essentially irreversible. Once a transfer is confirmed on the blockchain (the digital ledger that records all crypto transactions), there is no way to recover the funds.
The new protection currently covers 32 blockchain networks that operate on technology compatible with the so-called Ethereum Virtual Machine (EVM). Simply put, this is a technological standard on which many popular cryptocurrencies and decentralized applications run.
Supported networks include, for example:
- Ethereum
- BNB Smart Chain
- Polygon
- Optimism
- Arbitrum
- Avalanche
- Base
These blockchains rank among the most widely used in decentralized finance (DeFi) and cryptocurrency applications.

Fraud That Relies on Carelessness
According to Trust Wallet, address poisoning is among the fastest-growing types of cryptocurrency fraud. Globally, more than 225 million such attacks have been recorded, with confirmed losses exceeding 500 million dollars.
The principle of the scam is surprisingly simple.
The scammer first sends the victim a small amount of cryptocurrency from an address that closely resembles either a known service address or one the user regularly works with.
This transaction then appears in the wallet’s history. When an investor later needs to send crypto again, they often simply copy the address from the transaction history.
This is exactly the moment the fraudsters rely on. If the user fails to notice minor differences in the address, they may accidentally send the cryptocurrency to the attacker’s account.
Recent Attacks Cost Investors Tens of Millions of Dollars
According to available information, this type of fraud recently cost two investors a combined 62 million dollars in cryptocurrency.
One incident occurred in December 2025, when an investor lost 50 million USDt (a stablecoin pegged to the US dollar) precisely due to an address poisoning attack.
The incident sparked discussion about whether crypto wallets should automatically check suspicious addresses. Former Binance CEO Changpeng Zhao stated at the time that such protection should be standard.
“All wallets should simply check whether the receiving address is suspicious and block the user,” he wrote on the Binance Square social platform.

Similar Protection Available in Other Crypto Wallets
Trust Wallet is not the only cryptocurrency wallet introducing similar security tools. Filtering of suspicious transactions or protection against fraudulent addresses is also offered by other popular wallets.
These include, for example:
- Rabby Wallet
- Zengo Wallet
- Phantom Wallet
As cryptocurrencies grow in popularity, fraud attempts are increasing and pressure for security measures is mounting rapidly.
Security Is Key for Crypto Investors
For ordinary investors, one rule remains the same: cryptocurrencies give users full control over their money, but they also come with greater responsibility.
Once crypto is sent to the wrong address, there is practically no way to reverse the transaction.
This is precisely why new security features, such as checking suspicious addresses, can significantly reduce the risk of investors losing their funds to a relatively simple yet highly effective scam.
