Chainlink has announced its role as a founding partner in the **Open Transaction Layer (OTL)** through the Baseline Protocol Consortium. The initiative addresses a critical infrastructure gap: while blockchain networks scale, they need a **coordination layer** to manage: - Identity verification - Compliance requirements - Transaction messaging This builds on Chainlink's previous focus on interoperability solutions like LayerZero, Stargate, and Superchain. The OTL aims to provide standardized infrastructure for enterprise blockchain adoption. Learn more at [otl.network](http://otl.network)

Stripe has successfully processed more than $100 million in peer-to-peer USDC transfers on the Polygon network, demonstrating the viability of stablecoin payments at scale. **Key Points:** - Real-world payment infrastructure operating on open blockchain rails - Builds on Stripe's earlier integration of USDC checkout across 3M+ merchants - Polygon selected as settlement layer for its ability to handle enterprise-scale transaction volumes This milestone represents a significant step in mainstream adoption of blockchain-based payment systems.

**Major Payment Infrastructure Developments** - **Visa** integrated Polygon into its global stablecoin settlement program - **Meta** launched USDC creator payouts on Polygon, expanding to 160+ markets - **Modern Treasury** added Polygon as a native payments rail in its API **Ecosystem Growth** Polygon's stablecoin supply reached **$4.3B in April**, marking a 13.33% month-over-month increase. The network continues attracting payment-focused applications: - Coca Wallet shipped major updates including bank accounts and instant APY - SKALE Network deployed Portal 5.1 with 1-click crosschain bridging - Prophet Market AI launched V1 with AI prediction markets **Technical Updates** Trails v1.5 introduced composable actions on crosschain orchestration for the Open Money Stack, enhancing interoperability across the ecosystem. These integrations position Polygon as infrastructure for mainstream payment applications, with traditional finance companies and social platforms choosing the network for stablecoin settlement.

The Open Money Stack has released a crosschain orchestrator that enables users to execute complex, multi-step transactions across different blockchains in a single action. **Key features include:** - Composable flows that execute multiple steps through one intent - No approval transactions required for major stablecoins (USDC, USDT, DAI) - Integrated fiat onramps supporting credit cards and Apple Pay - Direct routing of deposits from Coinbase, Binance, and Kraken into transactions - Support for 18 mainnet chains, with Solana currently in testing The orchestrator simplifies crosschain DeFi interactions by removing the need for separate approval steps and allowing users to move seamlessly between different networks and protocols.

**Modern Treasury has integrated with Polygon** to support stablecoin payments through the Open Money Stack, a unified platform designed to simplify global money movement. **Key developments:** - Modern Treasury now supports Polygon Chain as a native payment rail within their API - The integration addresses the complexity of cross-border payments, which typically require 7+ different APIs - The Open Money Stack consolidates payments, stablecoins, wallets, on/off ramps, tokenization, and compliance into one modular system **Why it matters:** Moving money across borders has traditionally been fragmented and complex. By bringing Modern Treasury into the Open Money Stack, Polygon aims to make global money transfers as straightforward as moving data, with settlement happening on Polygon's network. The platform promises fast settlement, low costs, and global reach for real-world finance applications.
