Polygon

**Calastone**, the world's largest global fund distribution network, has selected **Polygon** for onchain settlement and reconciliation of institutional fund transactions. The platform processes over **$250 billion in monthly flows**, representing a significant move of traditional finance infrastructure onto blockchain rails. **Key implications:** - Institutional-grade fund transactions now settling onchain - Major validation of Polygon's infrastructure for TradFi use cases - Follows recent data showing Polygon handled 35% of global USD stablecoin transfers (168M in one week) This integration demonstrates growing institutional confidence in public blockchain networks for high-value financial operations.

**Latin America is reconstructing its payments infrastructure, with regional fintechs selecting Polygon as their foundation.** **Key developments:** - More stablecoins move on Polygon in Latin America than on all other EVM chains combined - Over half of stablecoin liquidity in emerging markets resides on Polygon - Polygon leads lifetime stablecoin transfer volumes in the region by a significant margin The shift represents a major infrastructure decision for the continent's financial technology sector, positioning Polygon as the dominant layer for payment rails in Latin American markets.

During a major DeFi security incident triggered by a forged signature, Polygon's Agglayer bridge continued operating without interruption, processing approximately $200M in bridge volume. **Key Points:** - Most DeFi bridges paused operations during the crisis - Agglayer remained operational due to its reliance on zero-knowledge proofs rather than multisignature wallets - The incident highlighted fundamental differences in bridge security models The event demonstrates how cryptographic proofs can provide continuous operation during security crises that affect human-managed systems. Agglayer's architecture uses mathematical verification instead of trusted signers, allowing it to maintain service when traditional multisig-based bridges shut down.

Polygon has released a new Agent Template on Pinata that enables developers to deploy yield optimizer agents without starting from scratch. **Key Features:** - Pre-built templates integrated with Polygon CLI - Automatic cross-chain fund movement to optimal yield vaults - Smart sessions for pre-approving vaults and spending limits - Multiple funding options: wallet, card, or exchange The template comes with cross-chain vault allocation, smart sessions, and spending controls configured out of the box. Developers can deploy functional agents on day one, significantly reducing setup time and complexity for building automated yield optimization tools.

Polygon reached a milestone of **7 billion lifetime transactions** as its payment infrastructure continues to expand with new integrations. **Key developments this week:** - Tether Wallet added support for USDT and XAUT on Polygon - Etherfuse, Bitso, and CapaFi enabled Mexican peso yield opportunities - WalletConnect reported over **$400 billion** moved through its protocol on Polygon - Tangem and MoonPay expanded their Polygon-based payment features - Binance completed support for the Giugliano upgrade **Network improvements:** Polygon Labs launched **sPOL**, a native liquid staking token, providing users with staking rewards while maintaining liquidity. The Giugliano upgrade, which went live earlier this month, brought faster finality and improved peer-to-peer throughput. The network continues to see growth in stablecoin activity, with peer-to-peer volume reaching $7.52 billion in March. Recent launches include onchain FX markets through partnerships with Frax Finance and Curve Finance, enabling currency swaps at lower costs than traditional cross-border payment systems.

**Polygon's Response to rsETH Incident** Polygon's infrastructure remains secure following the recent rsETH exploit. The team confirms: - **Polygon Chain, Agglayer, Katana, and Vaultbridge** are completely unaffected - Over **$2 trillion** has been safely processed to date - Active monitoring continues as the situation develops **Gearbox Protocol Takes Precautionary Measures** Gearbox curators report no direct exposure to rsETH, with the protocol operating normally. However, preventive actions include: - New rsETH exposure creation has been **restricted** - Borrowing against **tETH and DETH temporarily paused** - Limited indirect exposure through Balancer v3 LP tokens poses **no risk to lenders** - Loan-to-value ratios ensure solvency even in adverse scenarios Both teams emphasize their commitment to user safety and continue close monitoring of developments.

**Mastercard is transforming crypto payments** by replacing complex 42-character wallet addresses with simple, verified usernames for self-custody transfers. **Key developments:** - Polygon selected as the first network for Mastercard Crypto Credential - Users can onboard once, receive a verified username, and link their wallet - No more copying hexadecimal strings for transfers - Mastercard launched Crypto Partner Program to advance onchain payments - Polygon chosen for its low-cost infrastructure, speed, and scalability **How it works:** Mercuryo onboards verified users and issues credentials, while Polygon provides the blockchain infrastructure. The partnership aims to make global money movement onchain more accessible and user-friendly. This marks a significant step toward mainstream crypto adoption by simplifying the user experience for self-custody wallet transfers.

**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.
