A 14-year-old Bitcoin wallet containing 4,000 BTC has moved its funds following a series of OP_RETURN messages claiming to be from 'Salomon Brothers.' These messages, sent on June 30, July 2, and July 8, alleged the wallet was abandoned and provided a 90-day notice for repossession, which expired on October 10. The wallet's funds were moved on October 23, raising questions about the legitimacy of the notice and the entity behind it. The entity claiming to be Salomon Brothers reportedly sent similar messages to over 39,000 wallets, including one with over $8 billion in BTC. The legality of such repossession notices via blockchain messages remains untested in U.S. courts, leaving the situation unresolved.
