Coincorner and Anchorwatch Launch Insured Multi‑Signature Bitcoin Custody Service

Coincorner announced the launch of Vault, a Bitcoin custody service that combines multi‑signature security with insurance coverage underwritten by Lloyd’s of London.

Service Overview

Vault is offered in partnership with the custody firm Anchorwatch and is described as a multi‑signature, multi‑jurisdiction, multi‑institutional solution. Customers can deposit any amount of Bitcoin, track the holdings on‑chain, add more at any time, and withdraw whenever needed, subject to a small on‑chain transaction fee.

Insurance and Security

The custodial wallet is insured against loss of keys and unauthorised access, with the policy provided by the A+‑rated insurer Lloyd’s of London. Anchorwatch’s COO highlighted that the security model splits keys across independent companies and jurisdictions, aiming to deliver institutional‑grade protection to individual users.

Pricing

Vault charges an annual fee of 1.5%, billed monthly based on the Bitcoin value stored at the start of each month.

Context

The product launch follows recent high‑profile security incidents, including a compromise of Coldcard hardware wallets that resulted in the loss of nearly 2,000 BTC. These events have increased interest in custodial solutions that offer both technical safeguards and insurance.
