Major Update: AgentPay Firewall Is Now a Two-Sided x402 Payment Product

AgentPay Firewall has evolved from an engineer-facing policy prototype into a complete Seller-to-Buyer payment experience on Algorand.

What’s new

  • Seller workspace: Sellers can configure the USDC amount, receiving address, title, and payment description.
  • Signed payment links: Each request becomes a tamper-resistant checkout link with a seven-day expiration.
  • Buyer checkout: Buyers can review the exact payment terms and connect Pera Wallet before authorizing payment.
  • Direct x402 integration: The signed request maps to a live x402 v2 PAYMENT-REQUIRED challenge using @x402/avm.
  • Settlement evidence: The official AVM payment path has completed a verified USDC transaction through the GoPlausible facilitator on Algorand Testnet.
  • Automated verification: Hosted smoke tests validate the amount, recipient, network, asset, payment scheme, and token tamper protection.

The central product principle remains simple: Seller intent, Buyer consent, the x402 challenge, and the settlement receipt must all agree.
