As cryptocurrency adoption continues to grow, scammers are also becoming more creative. One increasingly common tactic used to steal funds is known as an address poisoning attack. Unlike traditional hacks, this scam does not involve breaking into your wallet or stealing your private keys. Instead, it relies on confusion, habit, and simple human error.
Because blockchain transactions are permanent and cannot be reversed, understanding how address poisoning works is essential for anyone who sends or receives cryptocurrency.
What Is an Address Poisoning Attack?
An address poisoning attack is a scam where a malicious actor sends a very small amount of cryptocurrency to your wallet from an address that closely resembles one you have used before.
The attacker’s goal is to make their fake address appear in your transaction history. Later, when you want to send crypto again, you may accidentally copy that address instead of the correct one and send funds directly to the scammer.
No wallet security is broken. The transaction is approved by the user, which makes the loss permanent.
Why Crypto Addresses Are Easy to Mix Up
Crypto wallet addresses are long strings of letters and numbers that are difficult to recognize or memorize. Because of this, most users rely on visual cues rather than checking every character.
- Addresses are copied and pasted instead of typed
- Wallet apps shorten addresses on screen
- Transaction history is reused for convenience
- Only the first and last characters are checked
Address poisoning attacks are designed to exploit these habits.
How Address Poisoning Attacks Work
These attacks usually follow a simple but effective process:
- You send crypto to an exchange, wallet, or smart contract
- The transaction becomes publicly visible on the blockchain
- A scammer copies the destination address
- They generate a similar-looking wallet address
- A tiny amount of crypto is sent to your wallet
- The fake address appears in your transaction history
- You accidentally copy it during a future transaction
- Funds are sent to the attacker’s wallet
Why Scammers Use Small Amounts
Scammers intentionally send very small amounts of crypto so the transaction does not attract attention. These deposits are often worth just a few cents.
These are commonly referred to as dust transactions. Their only purpose is to make the attacker’s address look familiar.
Blockchains Commonly Affected
Address poisoning attacks can occur on any blockchain where wallet addresses are public and reusable. They are especially common on:
- Ethereum
- Binance Smart Chain
- Polygon
- Tron
- Layer 2 networks used for DeFi
Why Address Poisoning Is Hard to Detect
Several factors make these attacks difficult to spot:
- Wallet apps truncate addresses
- Blockchain explorers show long transaction lists
- There are no scam warnings on-chain
- Transactions cannot be reversed
- Scammers do not contact victims directly
The scammer simply waits for a mistake.
How to Reduce Your Risk
Verify the Full Address
Always check the entire wallet address before confirming a transaction, not just the first and last characters.
Avoid Copying Addresses From Transaction History
Whenever possible, copy addresses directly from official sources such as exchange deposit pages or saved wallet contacts.
Save and Label Trusted Addresses
Most wallets allow you to save and label addresses, reducing the risk of copying the wrong one.
Send a Test Transaction
Before transferring a large amount, send a small test transaction to confirm the destination.
Use a Hardware Wallet
Hardware wallets display the destination address on a separate screen, making verification easier before approval.

Be Cautious With Unexpected Deposits
If you receive crypto you do not recognize, avoid interacting with the associated address without careful verification.
Frequently Asked Questions (FAQ)
Is address poisoning the same as hacking?
No. Address poisoning does not involve hacking your wallet or stealing private keys. It relies entirely on user error.
Can I recover funds sent to a poisoned address?
No. Blockchain transactions are irreversible. Once funds are sent, recovery is not possible unless the recipient returns them.
Does receiving unknown crypto mean my wallet is compromised?
No. Receiving unknown crypto does not mean your wallet is hacked, but it should be treated as a warning sign.
Are hardware wallets immune to address poisoning?
Hardware wallets reduce risk by displaying full addresses clearly, but users must still verify transaction details carefully.
