Detect address poisoning before reusing a crypto deposit address

Detect address poisoning before reusing a crypto deposit address

Address poisoning places a lookalike address into wallet history so a later user copies it instead of the intended destination. Matching only the first and last characters is not enough when an attacker deliberately imitates those characters.

Coinbase's educational article describes the attack pattern and defensive checks. It is an expert source, not proof that a particular wallet entry is malicious or that recovery is possible.

Recognize the poisoning pattern

Look for tiny unsolicited transfers or zero-value token events from an address sharing familiar starting and ending characters. The wallet may display truncated strings that make the malicious entry appear identical at a glance.

Treat unexplained activity as a warning and do not interact with embedded links or tokens. Address poisoning places a lookalike address into wallet history so a later user copies it instead of the intended destination.

The wallet may display truncated strings that make the malicious entry appear identical at a glance. Record the invoice reference and issuance time before preparing the transaction. Look for tiny unsolicited transfers or zero-value token events from an address sharing familiar starting and ending characters.

Return to the trusted invoice

Open the receiving service independently and generate or view the current deposit instructions for the intended account. A historical address may be expired, network-specific or unrelated even when it was once legitimate.

A historical address may be expired, network-specific or unrelated even when it was once legitimate. Confirm network and token contract in addition to the destination string. Open the receiving service independently and generate or view the current deposit instructions for the intended account.

Compare the entire destination

Use a secure copy-and-compare method or verified wallet address book and inspect multiple segments across the full address. Checking four characters at each end is exactly the behavior an attacker tries to exploit.

Checking four characters at each end is exactly the behavior an attacker tries to exploit. Cancel when any character, network or asset differs; never edit an address manually.

Review the signing screen

After pasting, compare the wallet's final destination with the trusted source again and inspect amount and fee. Clipboard malware can replace an address after the earlier comparison.

Respond to a suspected mistake

Preserve the transaction hash, contact wallet and receiving-service support, and report fraud through relevant local channels. Anyone promising certain recovery for an upfront fee may be running a second scam.

What the source supports

Coinbase address-poisoning explainer: The explainer supports obtaining addresses from trusted sources, checking the complete destination, using address-book controls carefully and avoiding blind copying from transaction history.

What the source cannot establish

It cannot authenticate a SignalBet invoice, reverse an on-chain transfer, inspect a private wallet, guarantee an address book is uncompromised or replace wallet-provider support.

Close with a documented decision

Never reuse a deposit address solely from recent history; open a current authenticated invoice and compare the full address, network and asset on the final signing screen.

A mistaken transfer is not a reason to deposit again. Adults 18+ should stop all gambling payments while an address discrepancy is investigated.

Build the final verification worksheet

For Detect address poisoning before reusing a crypto deposit address, create a one-page record containing the source, retrieval date, relevant account or transaction reference, confirmed fields, unresolved questions and the next safe action. In Crypto wallet safety, keep official evidence separate from personal inference. Use Coinbase address-poisoning explainer as the source anchor, then return to the live account, official portal or current rules for case-specific details. A reviewer should be able to reproduce each conclusion without receiving passwords, one-time codes, private keys or unrelated identity documents.
