Polygon Tracks 101 I Akshat Gada

Sun, Nov 2, 2025, 12:00 AM

Akshat Gada’s session, Polygon Tracks 101, introduces developers to the Polygon payments track and its integration with the X42 protocol, a blockchain-based payments standard designed for agentic and automated payments. The talk explains how X42 simplifies blockchain complexity through a “facilitator,” which handles on-chain settlement, verification, and gas fees—allowing agents or APIs to transact using simple HTTP requests. Akshat demonstrates how X42 enables seamless payments between a buyer and a seller (e.g., accessing a paid weather API), where the buyer first receives a 402 Payment Required response, then makes the payment through the facilitator, which finalizes the transaction on Polygon’s testnet. He then discusses how X42 enables agent-to-agent commerce, making micropayments and pay-per-use APIs frictionless. Developers are encouraged to build with TypeScript using the X42 Express and X42 Fetch packages, with Polygon as the supported network. The facilitator URL provided during the hackathon acts as a shared payment hub. Akshat suggests ideas such as monetized AI agents, paid MCP tools, and pay-to-crawl websites—highlighting Cloudflare’s example of charging AI crawlers for data access. He concludes by emphasizing that building on X42 early offers unique opportunities for innovation and potential grant support from Polygon for exceptional projects. 00:02 – Introduction & Hackathon Overview 00:31 – Polygon Payments Track with X42 Protocol 01:32 – What is X42 and How It Works 03:21 – Agentic Payments Flow (Buyer, Seller, Facilitator) 04:41 – Live Demo: Weather API Payment Example 07:04 – Building Paid MCP Tools with X42 08:15 – Why Use X42: Standardized Agent Payments 08:59 – Technical Setup: TypeScript, Express, and Fetch Packages 09:41 – Role of the Facilitator (Gasless Transactions) 10:32 – Project Ideas & Use Cases for X42 11:14 – Cloudflare “Pay-to-Crawl” Example 12:18 – Polygon’s Future Support & Builder Opportunities _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇮🇳 *ETHGlobal New Delhi* This workshop is specifically for ETHGlobal New Delhi, a 3-day hackathon held September 19-21 at the India International Convention & Expo Centre, bringing together the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem!
