A dormant Bitcoin address holding coins from the network's earliest days became the focus of a $285 billion legal dispute after Salomon Brothers filed notice via an on-chain OP_RETURN message in July 2025. The 1LwWt address, inactive for 14 years, received the demand requiring the owner to prove ownership by November 5, 2025.
The lawsuit centers on approximately 9.5 million BTC allegedly connected to Satoshi Nakamoto's original mining operations. Salomon Brothers embedded the legal notice directly into Bitcoin's immutable ledger, using the OP_RETURN field to broadcast the demand to the entire network. This unconventional legal tactic underscores the complexity of pursuing claims tied to early Bitcoin holdings where ownership remains ambiguous or the private keys may be lost entirely.
The 1LwWt address and similar dormant wallets from Bitcoin's first blocks represent a persistent puzzle in the crypto space. These addresses hold meaningful portions of Bitcoin's supply, yet have remained untouched since the 2009-2010 era when BTC traded at cents or remained worthless. The potential economic value of these holdings has exploded as Bitcoin matured into a trillion-dollar asset class.
Several parties have claimed to be Satoshi Nakamoto over the years, including Craig Wright, who faced legal challenges to his claims. The emergence of this lawsuit suggests renewed legal pressure on historically significant Bitcoin holdings. If the owner of 1LwWt fails to respond by the deadline, the lawsuit may advance to contest ownership or attempt asset recovery.
The on-chain notice demonstrates how courts and litigants now exploit blockchain's transparent, permanent infrastructure to serve legal documents. Rather than traditional methods, embedding messages in Bitcoin transactions creates irrefutable proof of notice across the network. This precedent could influence how future disputes involving crypto assets play out.
Bitcoin's price hovered around $42,000-$46,000 during the July 2025 notice period, putting the theoretical value of those dormant 9.5 million BTC well above $285 billion. However, accessing these holdings remains technically and legally fraught. The private keys controlling the address may be permanently lost, encrypted beyond recovery, or held by an unknown party who cannot be located.
The deadline of November 5, 2025 will reveal whether the address owner responds. Silence likely triggers litigation to determine rightful ownership or enable asset seizure proceedings. This case highlights the intersection of traditional property law and blockchain's immutable ledger, where fourteen-year-old silence may not constitute abandonment under legal scrutiny.
