CoinCorner and AnchorWatch have launched a Bitcoin custody service called Vault, a product that stores your Bitcoin using keys split between two separate companies and advertises insurance underwritten by Lloyd’s of London.
Custody simply means someone holds your Bitcoin for you. With Vault, that job is shared. CoinCorner’s official product page names CoinCorner and AnchorWatch as the independent entities that each hold the keys needed to move your coins.

The idea is that no single company controls your Bitcoin alone. CoinCorner says the service uses multi-signature technology, meaning more than one key is required to approve a transaction, with those keys spread across multiple jurisdictions.

English-language outlet crypto.news reported the launch for UK customers on September 8, 2026, though no dated official joint launch announcement was published. The exact launch date remains unconfirmed by an official source. For related coverage, see Visa Stablecoin Settlement Tops $20B Annualized Rate.
What is known about the custody arrangements
Multi-signature (often shortened to “multisig”) is like a safe deposit box that needs two different keys turned at once. CoinCorner holds one set of keys, and AnchorWatch holds another, according to the Vault product page. For related coverage, see Sality Botnet Disruption: Crypto Address Swaps May Persist.
Vault lets customers set their own identity-verification rules before any transaction goes through. In practice, that means you decide what checks must pass before your Bitcoin can move.
CoinCorner also says Vault insurance covers the loss of keys and unauthorised access, and is underwritten by the Lloyd’s of London insurance market. These are the company’s own coverage statements, not the terms of a policy that has been independently examined.
Readers should treat that carefully. Private insurance from the Lloyd’s market is not the same as government deposit protection, and the exact limits, exclusions and claims terms of the Vault policy were not published.
This concern over how much Bitcoin is really protected echoes recent security stories in the ecosystem, such as when the Liquid network recovered roughly 3,400 BTC after a reserve drain. Custody safety depends on the fine print, not the headline.
Availability, fees and terms for prospective customers
Vault advertises a 1.50% annual custody fee, billed monthly. On a holding worth $10,000, that works out to roughly $150 per year, charged in small monthly amounts.

CoinCorner says customers can add or withdraw funds at any time, with no long-term commitment. The precise withdrawal settlement mechanics were not independently checked.
There is an important regulatory point to understand. CoinCorner’s legal notice states that its cryptoasset investments are not regulated by the UK’s Financial Conduct Authority, sit outside the Financial Ombudsman Service, and are not protected by the Financial Services Compensation Scheme.
In plain terms, if something goes wrong, you cannot fall back on the same government safety nets that cover a normal UK bank account. The private insurance and the custody structure are the protections on offer, not a state guarantee.
One area the announcement does not spell out is inheritance. Vault does not publish who may authorise a withdrawal if a customer dies or becomes incapacitated, or what proof an heir would need to provide.
AnchorWatch separately announced its own product, called Multi-Institution Custody, which discusses documented authorization and inheritance continuity. Those are terms of that separate product, however, and they should not be assumed to apply to CoinCorner Vault.
Geographic availability and eligibility rules were also not detailed in the material published so far. The launch being reported does not, by itself, confirm the service is open to every customer or every jurisdiction.
For a regular Bitcoin holder, the practical takeaway is simple. Vault offers shared-key custody with advertised insurance at a 1.50% yearly cost, but check the coverage limits, withdrawal terms and inheritance rules directly with CoinCorner before committing any funds.
