CoinCorner rolled out Vault on Sept. 8, offering customers an insured Bitcoin custody service built with Anchorwatch and based on multisignature controls distributed across companies and jurisdictions. The company says Vault is available now, charges 1.5% annually in monthly installments and allows customers to add or withdraw Bitcoin, with withdrawals subject to an on-chain transaction fee. Anchorwatch COO Becca Rubenfeld said the arrangement combines multisignature custody with coverage through A+-rated Lloyd’s of London insurance. Customers can track insured holdings publicly on the Bitcoin blockchain, although CoinCorner materials say transfers into insured wallets typically occur on the first working day of the following month. The launch follows reports that Coldcard users lost close to 2,000 BTC after their hardware wallets were compromised, adding to security concerns after a series of hacks, bugs, data breaches and physical attacks in 2026. CoinCorner, Anchorwatch and BitGo had previously announced a multi-institution custody initiative in July that Anchorwatch CEO Rob Hamilton said was built on the company’s Trident Vault infrastructure.
