Coldcard Hacker's Wallet Becomes Unlikely Message Board for Desperate Victims

The Coldcard hacker's wallet has become an unlikely message board, where victims and others leave notes begging for the return of stolen funds. The address in question, bc1qq85v2c926eg6pgxhwp6q7lf6cnsz80qs3fcu9r, contains approximately $36 million worth of Bitcoin.

Each of these notes is attached to a small payment and will remain permanently on the blockchain. This phenomenon is made possible by OP_RETURN, a function that allows anyone to add text to a transaction.

The Coldcard breach occurred on July 30, resulting in verified losses exceeding $100 million. The victims are now using this unusual method to reach out to the hacker and plead for the return of their stolen funds.

However, not all messages are genuine; some appear to be money-laundering advertisements or attempts to take advantage of the situation. The notes offer a unique glimpse into the mechanics of the Bitcoin blockchain and the desperation of those affected by the breach.
