Verification of wallet addresses

Verifying wallet addresses is crucial in cryptocurrency transactions to prevent loss due to malicious activities like address poisoning attacks [00:00:55].

Address Poisoning Attacks

Address poisoning attacks are a specific type of scam where attackers attempt to trick users into sending crypto to a malicious address that visually resembles a legitimate one [00:00:00].

How Address Poisoning Works

Attackers monitor transactions on platforms like EtherScan or other transaction ledgers [00:00:07]. Upon detecting an incoming transaction to a user, they immediately send a transaction to that user’s wallet with an address that looks very similar to one the user might regularly interact with (e.g., their own second wallet) [00:00:11].

The similarity is achieved by making the first and last characters of the malicious address very close to the legitimate one [00:00:29]. In a browser view, the middle characters of the address may not be visible, making it difficult for users to spot the discrepancy at a glance [00:00:33].

For example:

If your address starts with 0x11 and ends in 563FD, an attacker’s address might also start with 0x11 and end in 563FD, making the full address appear identical in a truncated view [00:00:23].

Risks and Consequences

If a user is not paying close attention, they might mistakenly copy the malicious address from their transaction history, believing it to be a legitimate wallet they intend to send funds to [00:00:37]. This often happens when users are sending crypto between their own wallets [00:00:48]. The accidental transfer of a large amount of money to the wrong address has resulted in significant financial losses for many individuals [00:00:50].

Prevention and Best Practices

To prevent loss from address poisoning and ensure secure transactions, users should always adhere to the following best practices:

• Use the Direct Source: Always obtain the wallet address from the direct source, such as your own wallet interface or a verified contact, rather than copying from transaction history, especially after receiving an unexpected incoming transaction [00:00:57].
• Verify the Entire Address: Before sending any cryptocurrency, thoroughly verify that the exact address you intend to send to matches the one you have entered [00:01:03]. This includes checking not just the first and last characters but the entire string.

WARNING

People have lost tons of money from accidentally sending to the wrong address due to address poisoning. Always be aware and verify [00:00:53].
