Polygon

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.

**Key Developments This Week:** - **MoonPay** launched zero-fee stablecoin onramps for AI agents - **Polymarket** expanded into traditional asset markets using Pyth Network price feeds - **Mayan** has processed over $300M in cross-chain volume on Polygon to date - **TokenPocket** now supports zero-gas USDC transfers **Infrastructure Updates:** Polygon introduced a **private mempool** to improve transaction privacy and reduce MEV extraction. Polygon Labs also joined the x402 foundation under the Linux Foundation. **New Launches:** - Surf Liquid: stablecoin savings vaults - Rise Pay: onchain payroll solution - Euclid Protocol and Pagga both deployed on Polygon - BlockOps: bringing African financial infrastructure onchain These updates build on last month's Lisovo upgrade, which brought $1M in subsidized gas for agent payments and improved smart contract compatibility. Polygon continues expanding its stablecoin ecosystem, which recently hit a record $3.28B in supply.

Polygon has released official documentation for its **Agent CLI**, a new tool for building agentic payment systems. **Key Details:** - Documentation now available at [Polygon's payment services docs](https://docs.polygon.technology/payment-services/agentic-payments/polygon-agent-cli/) - GitHub repository accessible for developers to start building - Part of Polygon's broader payment services infrastructure The Agent CLI enables developers to integrate autonomous payment capabilities into their applications. The tool appears designed to facilitate programmatic transactions and payment automation within the Polygon ecosystem. Developers can now access both the technical documentation and source code to begin implementation.

A new abstraction layer enables agents to conduct all transactions using USDC without managing gas tokens like POL or ETH. **Key Features:** - Direct USDC payments for all transactions - No need to hold or manage native gas tokens - Automated handling through abstraction layer - Simplified transaction process for autonomous agents This development removes a significant friction point in blockchain operations, where users previously needed to maintain separate gas token balances alongside their transaction currencies. The abstraction layer automatically handles gas fee conversions behind the scenes, allowing agents to operate with a single stablecoin balance.

Polygon's **Lisovo Upgrade** went live on March 4, 2026, introducing several infrastructure improvements focused on AI agent transactions and payment systems. **Key Features:** - **$1M gas subsidy program** for agent transactions, offering rebates on Polygon x402 facilitator transactions - **Dynamic fee adjustments** without requiring hard forks - **Enhanced security standards** aligned with latest Ethereum protocols - **Improved wallet compatibility** and smart contract support The upgrade aims to reduce operational costs for developers building autonomous agent systems. Agents can now execute buy, sell, and transaction operations with subsidized gas fees. Polygon's Trails infrastructure supports natural language commands for cross-chain operations, enabling agents to swap tokens and move assets between networks without custom code.

**Major Payment Milestone Achieved** Visa merchants worldwide—150 million locations—now accept stablecoin payments through Oobit on Polygon, marking a significant expansion of crypto payment infrastructure. **Key Details:** - Payments work both in-store and online - Built on Polygon's fast, low-cost settlement layer - Follows 36.4% year-over-year growth in onchain activity **Network Performance:** Polygon stakers currently earn 8.33% APR, with 5.12% coming from actual network usage—demonstrating real economic activity beyond protocol rewards. This integration connects blockchain payment rails directly to everyday commerce, making stablecoins spendable at any Visa-accepting merchant globally.

**Polygon is implementing a major chain upgrade on March 4, 2026.** The upgrade introduces three key improvements: - **Faster agent-to-agent transactions** - optimized infrastructure for autonomous agent interactions - **$1 million gas fee subsidy** - reducing transaction costs for users and developers - **Enhanced compatibility** - improved wallet support and smart contract functionality This follows Polygon's previous network evolution where POL became the native token powering the aggregated blockchain network. The March 4 upgrade continues the chain's development as a scalable infrastructure layer. **What this means:** Lower costs and better tooling for developers building agent-based applications on Polygon, while users benefit from subsidized transactions during the transition period.

**QuickNode has integrated x402 payment support on Polygon**, marking another step in agentic payment infrastructure. **Why it matters:** - Agentic payments require fast, cheap, and final settlement rails - Polygon offers predictable fees and quick finality for automated transactions - The network already processes stablecoins reliably at scale **Recent momentum:** - Polygon accounts for 91% of APAC stablecoin transfer volume - Nearly 7.5M transactions processed in a single day - $1.49B in USDC supply reached a daily ATH This positions Polygon as infrastructure for the emerging agentic commerce layer.

Most payment companies excel at one layer - infrastructure, wallets, or fiat rails - but rarely all three. The Open Money Stack takes a different approach with a vertically integrated system that handles payments end-to-end. **Key Components:** - Infrastructure layer for transaction processing - Wallet solutions for user access - Fiat rail connections for traditional finance integration Sandeep Nailwal discusses the technical requirements for moving money at scale, emphasizing the need for systems that combine fast finality, low fees, and mathematical security. The approach builds on ZK technology to provide execution guarantees and settlement certainty. This integrated model addresses a gap in the current payments landscape, where fragmented solutions often create friction in the user experience.
