DoorDash puts 40 countries on stablecoins via Tempo, the UK folds payments + stablecoins + tokenized deposits + Open Banking under a single regulator, and the MCP protocol that agentic commerce is built on has spent a week with an unpatched RCE flaw Anthropic refuses to fix.

TODAYDoorDash puts stablecoins on 40-country payout rail via Tempo — first Fortune 500 non-fintech using stablecoin as primary operational rail
On April 21, the blockchain platform Tempo — valued at $5B (Stripe + Paradigm, led by Matt Huang, $500M raised in 2025) — announced a partnership with DoorDash to integrate stablecoin payments to merchants and Dashers across 40+ countries in the delivery three-sided marketplace. Tempo is designed specifically for corporate payment workloads (per Benzinga, sub-second settlement + fixed fees + private channels) and entered production five weeks ago with Mastercard, UBS, Klarna and Visa as infrastructure partners. DoorDash's move is not experimental — it replaces the cross-border treasury infrastructure that today processes billions annually in gig and merchant payouts. The non-obvious detail: this is not DoorDash doing "crypto" — this is DoorDash abandoning the traditional banking rail for operational flows. Correspondent-banking friction (asymmetric latency, FX volatility, cascade fees) becomes structurally incompatible with a 40-country marketplace paying micro-transactions in near-real time. Connection with the week's narrative: yesterday the DeFi bifurcation absorbed $10B of Aave outflows into USDC + Sky/Maker; today a non-fintech Fortune 500 converts stablecoins into operational treasury. Both signals connect: stablecoins are no longer retail speculation — they are multinational B2B infrastructure.
HM Treasury unifies payments, stablecoins, tokenized deposits and Open Banking into a single framework — PSR absorbed by FCA, Chris Woolard named Wholesale Digital Markets Champion
At UK FinTech Week on April 21, HM Treasury unveiled a unified regulatory framework covering traditional payments, stablecoins, tokenized deposits and Open Banking under a single authority — consolidating the Payment Systems Regulator (PSR) formally inside the FCA and expanding FCA powers over Open Banking. Chris Woolard CBE (EY, former interim FCA director) was named Wholesale Digital Markets Champion with an explicit mandate to accelerate capital-markets digitalization. The package adds £1M extra to CFIT (Centre for Finance, Innovation and Technology) and opens formal consultation on AI-agent-initiated payments — aligned with the simultaneous launch of the second cohort of the FCA's AI Live Testing (Barclays, UBS, Experian, GoCardless, Lloyds). Zeller puts UK losses from poor checkout UX at £22.7B per year ($30.6B) — the economic justification. The non-obvious piece: UK becomes the first G7 jurisdiction to collapse EVERY payments substrate under a single regulator. Europe stays fragmented (ECB + EBA + national supervisors); the US stays fragmented (Fed + OCC + FDIC + state regulators + CFPB); the UK now has the architectural advantage of regulatory coherence — especially critical with stablecoins + AI-agents converging.
OX Security confirms architectural RCE flaw in Anthropic's MCP — 200K vulnerable instances, Anthropic declines to patch, Bank of England AI forum warns of systemic banking risk
OX Security published on April 15 a technical advisory titled *"The Mother of All AI Supply Chains"* documenting an architectural remote-code-execution (RCE) vulnerability in Anthropic's Model Context Protocol (MCP) — the de facto standard connecting AI agents to tools and external data. The exposure numbers: 150M+ affected downloads, 7,000+ publicly accessible MCP servers, ~200,000 total vulnerable instances, 9 of 11 MCP registries poisonable in demo. OX executed commands on 6 production platforms — LiteLLM, LangChain and IBM LangFlow among the confirmed vulnerable. Anthropic confirmed the behavior is "by design" and declined to modify the protocol, assigning sanitization responsibility to the developer integrating MCP. On April 21 American Banker put the sectoral angle: US banks building agentic AI on MCP inherit unauditable supply-chain risk, and the Bank of England's AI forum explicitly warned of systemic contagion risk. The non-obvious piece: the entire bank-tier agentic stack runs on MCP — Mastercard Verifiable Intent, Amex ACE, Gr4vy ADK, Visa ICC, LiteLLM as middleware. While news celebrates agentic-rail launches, the layer wiring them to production systems has an RCE flaw whose maintainer refuses to repair. The first regulator to publish formal guidance on this third-party risk defines who captures the agentic-payments regulatory margin through 2027-2028.
News by Impact
STORIES[HIGH] Central Bank of Brazil activates MED 2.0 Pix rules: Nubank, Itaú and Caixa apply automatic limits and blocks. Estado de Minas (Apr 22) reports IN BCB 491/2024 enters into force forcing 72h precautionary holds on suspicious transactions and limits of R$200 per operation, R$1,000 daily for unregistered devices. The new MED 2.0 architecture is BCB's answer to the 2025 Pix-fraud epidemic. The structural data point: Brazil privileges the preventive mechanism (automatic limit) over the reactive one (post-fraud refund) — opposite model to European PSR3. Estado de Minas (Apr 22)
[HIGH] Block and Uber expand global partnership: Cash App Pay lands on Uber and Uber Eats USA — 59M Cash App MAU. PYMNTS (Apr 22) covers the deal: Cash App Pay checkout on Uber, coordinated promotions, 59M Cash App MAU as accepting base. Susan Anderson (Uber) positions it as access to "younger, more diverse consumers". The meaningful piece: Cash App becomes a commerce-wallet in one of the most consolidated US super-apps — Block turns its P2P into a payment-method for real-world spend. PYMNTS (Apr 22)
[HIGH] FCA launches AI Live Testing cohort 2: Barclays, UBS, Experian, GoCardless, Lloyds among the 8 consortia. FCA (Apr 22) confirms the second AI Live Testing round running probes with small-language models and neurosymbolic architectures on agentic payment initiation, automated KYC, predictive AML detection and retail credit modeling. Cohort 2 operationalizes the framework announced the same day by HM Treasury — the UK synchronizes regulator and government around agentic commerce. FCA (Apr 22)
[HIGH] Infinite launches dedicated FDIC bank accounts with embedded stablecoin + fiat, backed by Erebor Bank. Manila Times / PR Newswire (Apr 22) reports Infinite Accounts' debut: FDIC accounts with proprietary routing operating ACH, wire, RTP and stablecoins over a single API. Integrates mint/burn against fiat flows + smart routing between rails. Circle, Paxos and Brale as initial providers. It's the first US FDIC bank account with native stablecoin on the balance sheet — changing the KYC/AML workflow for cross-currency payments. Manila Times (Apr 22)
[HIGH] PACE Act introduced in US Congress: non-bank FinTechs get access to Fedwire, FedNow and ACH with 1:1 reserve under OCC supervision. MENA Fintech Association (Apr 22) covers the bipartisan introduction of the Payments Access and Consumer Efficiency Act by Young Kim (R-CA) and Sam Liccardo (D-CA). Entities holding 40+ state money-transmitter licenses could register as "covered providers" — eliminating dependence on the sponsor-bank model. 100% reserves in cash / Fed deposits / T-bills. Structural disruption for the US depository monopoly over Fed rails. MENA Fintech (Apr 22)
[MEDIUM] Help Net Security: 90% of banking breaches in 2025 financially motivated, 20% involve Shadow AI, 97% of affected organizations without adequate controls. Help Net Security (Apr 22) synthesizes 2025 financial-sector data: ransomware = 36% of incidents, average breach cost $5.56M, third-party breaches = 30%. JPMorgan, Citigroup and Morgan Stanley evaluated joint exposure from a shared third party. The critical number: 97% of organizations affected by Shadow AI lacked AI-specific controls — the precondition for the MCP risk of TOP 3. Help Net Security (Apr 22)
[MEDIUM] Bank of Korea's new governor backs CBDCs and deposit tokens — explicitly omits stablecoins. Cointelegraph (Apr 21) covers the new BOK governor's first formal address: Project Hangang (CBDC) + deposit tokens as core digital ecosystem, no mention of private stablecoins. Reflects the post-election policy line: South Korea goes CBDC-first, with Samsung Pay + KakaoPay as institutional wallets — opposite to the UK approach (stablecoin-friendly) announced on the same day. Cointelegraph (Apr 21)
[MEDIUM] Banco de la República evaluates expanding Bre-B Colombia to corporate payroll — 12.67M active keys, only 8.6% corporate. Infobae (Apr 21) reports the Colombian central bank's intent to bring Bre-B to real-time payroll. Colombia has 34.58M registered customers but only 8.6% of keys belong to legal entities — the structural gap the system aims to close by eliminating banking hours + file-loading windows. Replicates the Pix-Brazil model in corporate payroll before larger economies. Infobae (Apr 21)
[MEDIUM] Fime launches FACT framework in Singapore — security middleware for agentic commerce that validates AI intents against policy constraints. Fintech News SG (Apr 22) covers the commercial debut of FACT (Framework for Agentic Commerce Trust): middleware layer intercepting transactions initiated by AI agents, validating parameters against policy constraints and injecting cryptographic attestation into the authorization flow. It's the first commercial response to the MCP problem — what MCP doesn't do (sanitization), FACT does externally. Fintech News SG (Apr 22)
[MEDIUM] PayPal becomes exclusive P2P partner of the NFL — activation from the Pittsburgh Draft. SportsMarketing (Apr 22) reports the multi-year contract between PayPal and the National Football League: exclusive P2P in the most lucrative US sports league.
