Bitcoin and Lightning services firm Coincorner has launched Vault, a Bitcoin custody product developed with Anchorwatch that offers multi-signature security and insurance underwritten by Lloyd’s of London.
The service covers the loss of keys and unauthorised access, and is available now to Coincorner customers. It is designed to give users what the companies describe as institutional-grade protection while allowing them to manage their holdings through a Coincorner account.
“Introducing Vault – a new way to store your bitcoin. Built in partnership with Anchorwatch and designed to give you institutional-grade security from your Coincorner account,” Coincorner said on the social media platform X.
The company added that Vault was “available now for Coincorner customers.”
Coincorner first introduced the product on 8 September, describing it as a “multi-signature, multi-jurisdiction, multi-institutional, insured bitcoin custody service”. The launch follows a partnership announced in July involving Coincorner, Anchorwatch and BitGo, when the companies unveiled a multi-institution custody arrangement.
Anchorwatch chief executive Rob Hamilton said the service was built on the company’s “Trident Vault infrastructure”.
Under the arrangement, customers can transfer any amount of Bitcoin into Vault. The funds are placed in an insured wallet and can be publicly tracked on the Bitcoin blockchain. Users can add more Bitcoin whenever they choose and make withdrawals at any time, although withdrawals are subject to a small on-chain transaction fee.
Vault costs 1.5% a year, with the charge collected monthly and calculated according to the value of the Bitcoin held in the account at the beginning of each month.
Insurance is one of the product’s principal selling points. Hamilton said on X: “Thrilled to be working with Coincorner to offer insurance for their bitcoin in cold storage. For the first time, individuals can get access to a Lloyd’s of London policy for their bitcoin at an exchange.”
Becca Rubenfeld, Anchorwatch’s chief operating officer, said the service brought a form of protection usually associated with major institutions to individual Bitcoin users.
“This is what secure bitcoin custody should look like: multi-signature keys split across independent companies’ jurisdictions, insured by A+ rated Lloyd’s of London, and simple enough for anyone to use. With Vault, Coincorner is making institutional-grade protection something every bitcoin owner can actually have,” Rubenfeld said.
The launch comes after a series of hacks, losses and so-called wrench attacks reported across the cryptocurrency sector during the first eight months of 2026. Bitcoin users were particularly concerned after hardware wallets produced by Coldcard were compromised, with nearly 2,000 BTC taken from victims. Hacks, software bugs and data breaches have continued to raise concerns about the security of digital assets.
Some Bitcoin users have responded by adopting alternative security arrangements or using centralised custody services. Vault’s multi-signature design divides keys between independent companies and jurisdictions, while the insurance provides additional protection.
The model will not appeal to all self-custody supporters because it requires users to place trust in third parties. However, its combination of insurance and multi-party security could attract less technically experienced users, high-net-worth individuals and larger organisations.
