CoinCorner2026-09-08 20:16:20CoinCorner rolls out Lloyd’s-insured multisig Bitcoin vault with AnchorWatchCoinCorner, a British bitcoin exchange based in the Isle of Man, has launched a new multisignature BTC custody product called Vault in partnership with U.S. firm AnchorWatch. Under the setup, control of customer keys is split between the two companies, and the holdings are insured by Lloyd’s of London. CoinCorner said the service carries a 1.5% annual fee and is aimed at bitcoin owners seeking cold-storage security without having to manage hardware devices on their own. The company said customers can open a Vault account and deposit any amount of bitcoin, though assets do not move into the insured wallet right away. Transfers are typically processed on the first working day of the following month, and customers can verify holdings on-chain through a wallet address provided by CoinCorner. The firms also said users may add funds at any time and can set their own identity-verification rules before assets are allowed to move. The launch follows the Coldcard wallet hack referenced in the report, in which single-signature bitcoin wallet users lost funds after attackers exploited a firmware bug that led to weak seed generation. About $115 million was lost, according to the article. Bitcoin Magazine said the new service was first reported in a piece written by Mathew Di Salvo.780
Bitcoin2026-09-08 16:10:49CoinCorner and AnchorWatch Launch Insured Bitcoin Custody Vault for UK ClientsCoinCorner has partnered with AnchorWatch to launch Vault, a multi-institution bitcoin custody service for clients in the United Kingdom, according to a post by Bitcoin News on X, as reported by ChainCatcher. The service is insured by Lloyd’s. CoinCorner and AnchorWatch hold separate keys, meaning neither party can transfer a client’s bitcoin on its own. All bitcoin deposits under the service are covered by insurance.740

Bitcoin2026-08-08 17:31:03Bitcoin Red Team Says AI Scans Found More Than a Dozen Vulnerabilities Across 150 RepositoriesA volunteer security effort focused on Bitcoin says it has used several frontier AI models to scan 150 repositories and uncover more than a dozen vulnerabilities, highlighting how artificial intelligence is being used more aggressively in blockchain security reviews. AnchorWatch CEO Rob Hamilton said on X earlier this week that the group has spent about $20,000 on AI services while building what he described as a "Bitcoin red team" platform, adding that funding is already secured and donations are not needed. Hamilton said the initiative relies on Kimi K3, OpenAI’s GPT Sol, Anthropic’s Claude Fable and Opus models, and Z.ai’s GLM 5.2 to detect vulnerabilities and produce supporting documentation. He also said the team received help from OpenAI to get a system called Cyber Harness running, describing it as a more expensive scan that has already produced results for key parts of the Bitcoin ecosystem. Pseudonymous developer Calle said the group has built multiple AI-powered review systems for wallets, cryptographic libraries, infrastructure, and other Bitcoin projects, and claimed the team is finding roughly one critical exploit per hour per person. The team said it reported critical vulnerabilities to several projects in the last 12 hours, but did not name the affected projects or disclose technical details.1880
Bitcoin2026-08-08 10:40:10Kimi K3 flags 4,962 flaws in 24-hour Bitcoin ecosystem audit as Coldcard fallout deepensBitcoin developers say an AI-assisted security sweep has exposed thousands of weaknesses across the broader ecosystem just as the fallout from the Coldcard wallet exploit continues to unsettle users and traders. A volunteer team said it scanned about 390 Bitcoin-related projects in roughly 24 hours and found 4,962 security issues, including 85 critical bugs and 635 high-severity flaws, calling the state of ecosystem security "extremely bad." The group, now 16 people working in shifts around the clock, is using Moonshot’s open-weight Kimi K3 model, with daily compute costs of about $10,000 covered by OpenSats. At the same time, Coldcard is still urging users to move funds after an exploit tied to a five-year-old key-generation defect led to the theft of nearly 2,000 BTC from more than 5,200 addresses over several days. One wallet linked to the attacker still holds about $36 million in bitcoin, while on-chain messages sent to that address include pleas for the funds to be returned and at least one message offering laundering services for a 10% fee. The overlap between AI-powered defense and AI-assisted exploitation has become a central concern.1760
