Coinbase's x402 facilitator now supports Polygon, enabling autonomous agents to process payments with gasless transactions and built-in compliance for USDC.​

Key features:

  • Sub-2-second settlement for high-volume microtransactions
  • One-line code integration
  • Built-in compliance for agents accepting USDC payments
  • Optimized for autonomous agent payment rails

This integration follows Polygon's recent infrastructure upgrades, including the Lisovo hardfork that introduced $1M in subsidized gas for agent-to-agent payments and the launch of the Polygon Agent CLI toolkit.​

Polygon continues positioning itself as the leading chain for agentic commerce, with growing adoption from payment facilitators choosing its fast, low-cost settlement infrastructure.​

Zooming out, we've recognized that institutional Ethereum isn’t about “L2s vs L1s” anymore. Simply because institutional Ethereum requires more than scaling blocks, it requires infra that can actually move money. Who's actually building the rails that move money? A deeper look
