Bitcoin custody is getting a serious infrastructure upgrade this week, and two separate announcements show just how quickly the space is maturing.
Block Wants to Be Your Bitcoin Bank
Jack Dorsey's payments company Block has applied for a bank charter, according to Decrypt. The proposed entity, called Builders Bank, would consolidate the custody work Block currently runs across more than 50 state money transmitter licenses into a single, federally regulated structure. That's a meaningful operational shift. Right now, holding customer Bitcoin across dozens of state-level licenses creates compliance overhead and legal fragmentation. A bank charter simplifies that—and, more importantly, signals that Block views Bitcoin custody as a long-term core business rather than a side function.
The application is still pending. Regulatory approval for new bank charters is rarely fast. But the intent is clear: Block wants to hold Bitcoin for its customers under one roof, with one set of rules.
CoinCorner Goes Multisig With Lloyd's Backing
Separately, British exchange CoinCorner announced a multisig Bitcoin custody service built with AnchorWatch and insured through Lloyd's of London, according to Bitcoin Magazine. Multisig requires multiple private keys to authorize a transaction, which means no single point of failure can drain a wallet. The Lloyd's insurance layer adds an additional backstop if something goes wrong.
This matters because insurance for Bitcoin custody has historically been hard to obtain and easy to oversell. A named Lloyd's policy attached to a named multisig architecture is a concrete, verifiable claim—not a vague assurance. CoinCorner is a relatively small exchange, but this kind of product, if it performs as described, sets a template others can follow.
Why Custody Dominates Right Now
The timing of both announcements isn't random. A Liquid sidechain hack reported by Decrypt left roughly 600 BTC—about $47 million at current prices—still unrecovered after hackers returned most but not all of a roughly 4,000 BTC theft. Some observers doubt the actors involved deserve the "white hat" label being applied to them. That ongoing situation is a live reminder of what poor custody architecture can cost.
Meanwhile, institutional buyers keep adding Bitcoin. Decrypt reported that Strive, the asset manager associated with Vivek Ramaswamy, added 1,375 BTC last week—its third straight week of significant purchases—pushing its preferred stock offering toward the billion-dollar mark. Bitcoin Magazine noted that Capital B bought 376 BTC in its largest single purchase of 2026. When institutions accumulate at this pace, the question of where and how those coins are held becomes genuinely important, not just procedural.
The Bigger Picture
Block's charter application and CoinCorner's vault product represent two different approaches to the same problem: making Bitcoin safe to hold at scale. One is top-down—federal regulation, consolidated oversight. The other is technical—cryptographic key distribution backed by traditional insurance. Neither approach alone is sufficient. Together, they reflect an industry trying to grow up before the next major security failure forces the issue.
- Block seeks a single federal charter to replace 50+ state licenses for Bitcoin custody
- CoinCorner launches a Lloyd's-insured multisig vault built with AnchorWatch
- ~600 BTC remains missing from the Liquid hack, keeping custody risk visible
- Institutional buyers including Strive and Capital B continued accumulating this week
Stronger custody infrastructure benefits everyone who holds Bitcoin—including the charities that receive it as donations. Knowing coins are securely held from the moment a donor sends them to the moment a charity spends them is exactly the kind of trust that makes Bitcoin giving viable long-term.
