CoinCorner and AnchorWatch have brought a new insured Bitcoin custody option to everyday holders, pairing exchange-account convenience with multi-signature control and coverage arranged through Lloyd’s of London.Isle of Man-based CoinCorner, a Bitcoin and Lightning company that has served customers for more than a decade, has rolled out a product branded Vault.
The service is built with US custody and insurance specialist AnchorWatch and is designed so users can keep bitcoin in cold storage without assembling hardware wallets, managing seed phrases, or running their own multi-sig setup.
CoinCorner describes the offering as multi-signature, multi-jurisdiction, and multi-entity custody, with insurance that addresses loss of keys and unauthorised access.
Under the Vault model, control of customer bitcoin is split between two independent firms in different jurisdictions.
CoinCorner holds one signing key and AnchorWatch holds the other, so neither party can move funds on its own.
That structure is meant to reduce single-custodian and single-jurisdiction risk while keeping the user experience inside a familiar CoinCorner account.
Customers can also set their own identity checks that must be completed before a transfer is authorised, adding a custom theft-protection layer on top of the cryptographic quorum.
Insurance is the product’s most visible selling point.
Bitcoin stored in Vault is covered under a policy underwritten in the Lloyd’s of London market, according to both companies.
AnchorWatch, a Lloyd’s coverholder, has spent several years combining Bitcoin-native vault software with optional institutional-style insurance.
Company executives have framed Vault as a way to give retail holders protections that were previously associated mainly with large institutions.
CoinCorner chief executive Danny Scott has said the partnership lets the exchange offer insured multi-signature custody without forcing customers through a technical setup.
AnchorWatch COO Becca Rubenfeld has described the design as keys split across independent firms and jurisdictions, backed by Lloyd’s capacity, and simple enough for non-specialists to use.
The commercial terms are straightforward.
Vault costs 1.5 percent a year, billed monthly on the bitcoin balance recorded at the start of each month.
Users can add funds at any time and are not locked into a long-term contract.
Withdrawals can be made back to a standard CoinCorner bitcoin balance, after which ordinary on-chain fees may apply.
Some reporting notes that deposits opened in Vault may not move into the insured multi-sig wallet immediately and can settle on the first working day of the following month, with holdings visible on-chain through an address provided by CoinCorner.
The companies say the bitcoin is not lent or reused.
The launch sits against a wider debate about how people should store bitcoin after high-profile hardware-wallet losses and social-engineering attacks. AnchorWatch and CoinCorner had already collaborated earlier in 2026 on a broader multi-institution custody model that can also involve BitGo in a 2-of-3 arrangement.
Vault, as marketed to CoinCorner customers, is presented as a two-key version of that idea: institutional-grade security without asking users to become their own operations team.
Important caveats remain.
CoinCorner’s crypto services are not authorised by the UK Financial Conduct Authority and are not covered by the Financial Services Compensation Scheme. Private insurance applies only to specified events such as key loss and unauthorised access; it does not protect against price declines or every operational failure.
Prospective users should review policy wording, settlement timing, and identity-verification rules before moving coins.
For holders who want cold storage discipline without the operational burden of self-custody, Vault is an attempt to productise multi-sig and insurance inside a retail exchange account. Whether the 1.5 percent fee is worth that trade-off will depend on each user’s risk tolerance, technical comfort, and need for insured recovery paths.
