Mastercard completed its $1.8 billion acquisition of London-based stablecoin infrastructure provider BVNK on August 3, 2026. The transaction pays $1.5 billion upfront with up to $300 million in earnouts tied to performance targets, closing months ahead of its original year-end timeline. BVNK handles $30 billion in annualized payment volume across 130 countries, providing APIs that let financial institutions route funds between traditional bank accounts and blockchain networks. Integrating these on-chain rails gives Mastercard direct ownership over cross-border B2B transfers, treasury flows, and automated settlements without routing transactions through correspondent banks. Mastercard chose full ownership over alternative routes. Rival payment providers are pursuing starkly different strategies: Stripe acquired stablecoin platform Bridge for $1.1 billion in 2025, while Visa relies on external partnerships rather than dedicated infrastructure buyouts. The deal ranks as Mastercard's third-largest purchase this decade, behind its $3.19 billion acquisition of Nets and $2.65 billion purchase of Recorded Future. Mastercard stock closed down 0.4% at $570.97 following the announcement.

PowerCompute consolidated three debt facilities totaling $18 million into a single Bitcoin-backed credit line with Arch Lending carrying an initial 2% APR, according to Cointelegraph. The new facility replaces an $11 million loan from Galaxy Digital alongside two loans totaling $7 million from SE and AJ Liebel that carried 12% interest rates. To secure the loan, the Nasdaq-listed miner pledged 307 Bitcoin from its treasury. The transaction slashes interest expenses on the debt used to acquire its 15-megawatt Oklahoma facility and 11-megawatt Mississippi facility while allowing PowerCompute to keep its cryptocurrency exposure. Arch Lending holds the Bitcoin as collateral under terms that reset the interest rate every 30 days based on prevailing market conditions. If Bitcoin prices fall, PowerCompute faces margin calls requiring it to post additional treasury tokens.

Sixteen Bitcoin developers used artificial intelligence tools to identify 4,962 software vulnerabilities across 390 projects in a single 24-hour audit, according to reporting from coindesk.com. The coordinated sweep uncovered 85 critical and 635 high-severity bugs embedded in crypto wallets, cryptographic libraries, and core infrastructure code. Pseudonymous developer Calle and collaborator Rob Hamilton led the group by pointing custom AI review harnesses and off-the-shelf models directly at open-source codebases. Project maintainers are now overwhelmed by the sudden flood of automated reports and local proof-of-concept exploits requiring verification. Finding flaws takes seconds, but routing and fixing them requires scarce human attention. The bottleneck has shifted entirely to triage. The sudden influx underscores a dangerous asymmetry: attackers possess the same automated scanning tools as security researchers. The audit follows a real-world breach beginning July 30, where attackers exploited a dormant firmware flaw in Coldcard wallets to steal up to $114 million from affected users.
