Settlement Infrastructure
Cross-Border and Enterprise
1. Tassat Group - Yield-in-Transit Patent (U.S. Patent No. 12,489,632)
What Changed: Tassat secured a U.S. patent for on-chainA decentralized, digital ledger of transactions maintained across multiple computers Yield-in-Transit (YIT) technology, enabling institutions to accrue intraday interest during settlement operations. The patent covers interest accumulation and distribution mechanisms for 24/7, high-velocity settlement environments. The technology powers Lynq, an institutional settlement network launched in July 2025 with over 50 institutions onboarding, backed by U.S. Bank, Avalanche, B2C2, Crypto.com, Fireblocks, Galaxy, FalconX, and Wintermute.
Why It Matters for Infrastructure: This patents a foundational mechanism that directly improves capital efficiency for institutional settlement infrastructure. By enabling continuous interest accrual during transit, YIT removes friction from collateral management, reserve operations, and RWATangible assets represented on-chain settlement - allowing market makers, exchanges, custodians, and stablecoinA cryptocurrency pegged to a stable asset, such as USD or gold issuers to optimize liquidityThe ease with which an asset can be bought or sold without affecting its price operations in real-time. This addresses a material gap in how 24/7 blockchainA decentralized, digital ledger of transactions maintained across multiple computers settlement can match or exceed legacy finance's capital productivity. The Lynq network's 50+ institutional onboarding and patent protection signal this technology is moving from prototype to regulated production deployment.
2. OCC Interpretive Letter 1188 - Riskless Principal Crypto Transactions
What Changed: The Office of the Comptroller of the Currency issued Interpretive Letter No. 1188 on December 8, 2025, confirming that national banks may engage in riskless principal crypto-asset transactionsA transfer of value or data recorded on a blockchain, verified by network participants, and permanently added to the distributed ledger. Under this model, banks act as intermediaries matching offsetting customer trades without holding inventory on their balance sheets, mirroring existing securities riskless principal authority.
Why It Matters for Infrastructure: This regulatory clarification directly enables bank participation in crypto market-making and intermediation without capital constraints or balance-sheet risk. It extends existing bank authority (already granted for securities) to digital assets on a technology-neutral basis, removing a regulatory barrier to institutional crypto market infrastructure. Banks can now legally operate as market makers and liquidityThe ease with which an asset can be bought or sold without affecting its price providers, materially increasing institutionalization of trading infrastructure and reducing reliance on crypto-native exchanges. This compounds with earlier 2025 clarity on custody and stablecoinA cryptocurrency pegged to a stable asset, such as USD or gold issuance, building a complete regulatory stack for bank participation.
3. MetaComp Series A Funding ($22M) - Stablecoin Settlement Infrastructure, Asia-Pacific
What Changed: Singapore-based MetaComp raised $22M Series A for StableX Network, a Web2.5 cross-border settlement infrastructure unifying SWIFTGlobal messaging network for international bank transfers and stablecoinA cryptocurrency pegged to a stable asset, such as USD or gold rails. The funding round was backed by Eastern Bell Capital, Noah, Sky9 Capital, Freshwave Fund, and Beingboom Capital. MetaComp operates with a Major Payment Institution license from Singapore's Monetary Authority and now processes over $1 billion monthly across 30+ markets. StableX Engine supports 10+ major stablecoins (USDTThe largest stablecoin by market cap, pegged 1:1 to the US Dollar and issued by Tether Limited, USDCA fully-reserved stablecoin pegged 1:1 to the US Dollar, issued by Circle and backed by regulated financial institutions, RLUSD, FDUSD, PYUSDA stablecoin issued by PayPal and Paxos, pegged 1:1 to the US Dollar and designed for payments and transfers, WUSD) and integrates VisionX compliance engine for real-time KYTAn automated compliance mechanism that screens financial transfers against risk indicators and sanctions lists monitoring and risk scoring.
Why It Matters for Infrastructure: This funds a regulated stablecoinA cryptocurrency pegged to a stable asset, such as USD or gold settlement layer that directly addresses cross-border payment infrastructureInfrastructure and networks that enable money transfer between parties gaps for institutions. The "$1B+ monthly volume" metric demonstrates product-market fit for institutional B2B flows across Asia-Pacific, Middle East, and South Asia. VisionX's integration of compliance monitoring with settlement rails is material: it embeds AMLRegulatory framework requiring financial institutions to detect and prevent money laundering, terrorist financing, and other illicit financial activities/KYTAn automated compliance mechanism that screens financial transfers against risk indicators and sanctions lists logic directly into the plumbing rather than layering it on top, reducing friction and enabling institutions to achieve settlement + compliance simultaneously. This model is exportable and signals fintech infrastructure capital is flowing toward regulated, compliance-first settlement rails, not speculative DeFiFinancial systems built on blockchain that operate without intermediaries like banks.
4. Flutterwave + Polygon Cross-Border Payments Partnership
What Changed: Africa's largest payments infrastructure, Flutterwave (processed $40B+ to date), selected PolygonA scaling network built on top of Ethereum that processes transactions faster and cheaper than the main Ethereum blockchain as its default blockchainA decentralized, digital ledger of transactions maintained across multiple computers for a multi-year stablecoinA cryptocurrency pegged to a stable asset, such as USD or gold-powered cross-border payments product. The partnership enables instant, low-cost cross-border transfers with stablecoin rails supporting corporate payouts (e.g., Uber driver payments) and consumer remittances. A pilot with Flutterwave for Business customers launched in late 2025; full rollout to all enterprise and consumer users (Send App) is scheduled for 2026, targeting 30+ African countries.
Why It Matters for Infrastructure: This represents a material shift in real-world adoption of stablecoinA cryptocurrency pegged to a stable asset, such as USD or gold settlement infrastructure in emerging markets - moving from protocol-native use cases to mainstream commercial payment flows. Flutterwave's scale (40B+ historical volume) and enterprise customer baseCoinbase's Ethereum Layer 2 network using Optimism's OP Stack, designed for low-cost, high-speed transactions with Coinbase ecosystem integration (Uber, Audiomack) validate stablecoins as a settlement layer for high-volume, cross-border B2B and remittance flows. The reduction of settlement costs from 8%+ to sub-$0.01 and near-instant clearing directly improves capital efficiency for millions of end-users and businesses. This is a live, regulated, high-volume deployment of stablecoin rails - not a pilot or whitepaperA document outlining the technical details and purpose of a blockchain project.
5. IBM Acquisition of Confluent ($11B) - Real-Time Data for Blockchain Settlement and AI Compliance
What Changed: IBM completed an $11B acquisition of Confluent, the streaming data platform provider. IBM positioned this acquisition as foundational to hybrid on-chainA decentralized, digital ledger of transactions maintained across multiple computers/off-chain systems, tokenized settlement, programmable money, and real-time compliance automationUsing technology to automate regulatory compliance processes. Confluent's real-time event streaming will enable institutional crypto operations to synchronize blockchain events with enterprise infrastructure, power AIAI systems that learn patterns from data without explicit programming-driven risk and compliance monitoring, and facilitate settlement across tokenized assetsTangible assets represented on-chain.
Why It Matters for Infrastructure: This is a top-tier enterprise software company (IBM, $200B+ market capThe total value of a cryptocurrency, calculated as price multiplied by circulating supply) making a major M&A bet that real-time data streaming is critical plumbing for institutional blockchainA decentralized, digital ledger of transactions maintained across multiple computers adoption. The strategic focus on "hybrid on-chain/off-chain systems," "programmable money and settlement," and "risk, fraud, and compliance automationUsing technology to automate regulatory compliance processes" signals IBM views tokenizationConverting real-world assets into digital tokens on a blockchain and settlement as enterprise-grade infrastructure problems requiring legacy tech stack integration. This validates that institutional adoption requires not just blockchain but enterprise data infrastructure that connects on-chain and off-chain events. It materializes a multi-year capital commitment to closing the integration gap between fintech and tradfi.
6. Major Retailer Stablecoin Settlement Pilot - USD-Backed Instant Point-of-Sale Settlement
What Changed: Following the "Payment Stablecoin Clarity ActUS legislation defining the market structure and jurisdictional oversight for trading payment stablecoins" (passed earlier in 2025), major national retail chains launched a pilot program enabling customers to pay with approved stablecoins (USDCA fully-reserved stablecoin pegged 1:1 to the US Dollar, issued by Circle and backed by regulated financial institutions, PYUSDA stablecoin issued by PayPal and Paxos, pegged 1:1 to the US Dollar and designed for payments and transfers) at point of sale, with merchants receiving settled USD instantly. The system uses Layer-2 networks for transactionA transfer of value or data recorded on a blockchain, verified by network participants, and permanently added to the distributed ledger processing, replacing credit-card settlement (which charges 2-3% fees and takes days) with stablecoinA cryptocurrency pegged to a stable asset, such as USD or gold-based clearing that is nearly instant and nearly free.
Why It Matters for Infrastructure: This is the first material mainstream retail deployment of stablecoinA cryptocurrency pegged to a stable asset, such as USD or gold rails for settlement - moving stablecoins from a crypto-native payment mechanism to a competitive settlement layer against Visa/Mastercard. The regulatory clarity (Clarity ActUS legislation defining the market structure and jurisdictional oversight for trading payment stablecoins) combined with merchant adoption demonstrates that stablecoins are transitioning from speculation to infrastructure. If the pilot scales to mid-2026 rollout as projected, it would represent a structural shift in payment settlement architecture for millions of retail transactionsA transfer of value or data recorded on a blockchain, verified by network participants, and permanently added to the distributed ledger, reducing payment costs and enabling instant clearing. This directly challenges the Visa/Mastercard duopoly on settlement and shows how regulation + institutional behavior is shifting.
