CoinCorner, a British bitcoin exchange based in the Isle of Man, has introduced a new multisignature (multisig) Bitcoin custody service in partnership with U.S.-based AnchorWatch. Holdings in this new vault are insured by Lloyd’s of London, a leading global insurance provider.
Cold-storage security with simplified access
The multisig custody service is tailored to customers who prioritize the safety of cold-storage without the burden of managing their own hardware wallets. CoinCorner charges an annual fee of 1.5% for the service, aiming to streamline access for bitcoin holders seeking robust protection for their assets.
This launch follows a recent high-profile exploit in the crypto community involving the Coldcard wallet. In that incident, hackers exploited a firmware vulnerability affecting single-signature wallets, resulting in the theft of approximately $115 million in bitcoin. The breach raised renewed concerns about the risks associated with single-key storage and highlighted the growing preference for multisig solutions among security-conscious investors.
Vault offers a straightforward setup for customers and, through AnchorWatch, delivers fully insured, multisignature custody with the simplicity that CoinCorner users have come to expect, said CEO Danny Scott.
Vault structure and customer control
With the Vault, CoinCorner splits key control between itself and AnchorWatch, effectively reducing single points of failure. Customers can open a Vault and deposit any chosen amount, setting their own identity verification requirements for fund movement. However, deposits are not immediately transferred into the insured wallet. Instead, CoinCorner processes transfers to the Vault on the first working day of the following month. Once transferred, holdings can be transparently verified on-chain via wallet addresses provided to each customer.
Top-ups can be performed at any time, granting users continuous flexibility over their holdings. CoinCorner also stated it is the first service globally to offer this specific type of fully insured, automated multisig vault product. The company positions Vault as an accessible, insurance-backed solution designed to overcome common barriers to secure bitcoin custody.
Making multisig more accessible
Multisig wallets involve dividing access to multiple private keys across different custodians or devices, providing an additional security layer compared to single-key systems. Despite their security advantages, multisig wallets have traditionally been viewed as too complicated for mainstream users, requiring the management of several devices, creating and backing up multiple private keys, and maintaining records regarding key locations.
CoinCorner and AnchorWatch seek to eliminate these obstacles by managing the technical aspects on behalf of customers. The service distributes and manages keys, allowing users to benefit from the full protective properties of multisig, without the need for complex technical setup.
As the crypto industry evolves, new technological solutions are reshaping how investors interact with both digital and traditional assets. While traditional markets rely on complex brokers, a significant shift is occurring as Wall Street adapts to Web3 platforms. Investors are now increasingly using services like 1stepSwap, enabling them to hold tokenized shares of major U.S. companies, as well as gold and silver, directly in their crypto wallets. These platforms remove intermediaries by tokenizing real-world assets (RWAs) and automatically acquiring the best market prices in seconds.
CoinCorner and AnchorWatch are positioning their offering as a step forward in this broader industry shift towards secure, user-friendly digital asset management.
By handling key distribution and offering on-chain verification, Vault aims to deliver the security benefits of multisig without the operational complexity that has previously deterred many from adopting this approach.
