Overview
Pay for web content instantly with seamless x402 micropayments. Full control. No accounts or logins.
Primer Pay is a browser wallet that automatically handles x402 micropayments as you browse. When you visit content protected by an x402 paywall, Primer Pay seamlessly authorizes payment and unlocks access - no signup forms, no subscriptions, no friction. How it works The x402 protocol enables websites to request small payments (from fractions of a cent upwards) directly over HTTP. When you visit an x402-enabled site, Primer Pay detects the payment request, checks it against your configured limits, and if approved, signs a gasless USDC authorization. The content unlocks instantly, and you continue browsing. Key features ⛽ Gasless transactions - Pay with USDC without needing ETH for gas. Payments are processed through EIP-3009 authorizations. 🔌 Multi-network support - View balances and make payments across Base, Ethereum, Arbitrum, Optimism, and Polygon. 💰 Spend controls - Set per-payment limits, daily caps, and confirmation thresholds. You decide how much can be spent automatically. 🛑 Domain allowlist - Restrict payments to specific trusted domains. 📜 Transaction history - Track all payments by domain, amount, and network. Export to CSV. 👮♂️ Self-custody - Your keys never leave your device. Wallet data is encrypted with AES-256-GCM and protected by your PIN. Getting started • Install the extension and create a new wallet (or import an existing one with a recovery phrase or private key) • Fund your wallet with USDC on Base • Configure your spend limits in Settings • Browse x402-enabled sites - payments happen automatically within your limits Security Primer Pay is a non-custodial wallet. Your private keys are generated locally, encrypted, and never transmitted. We cannot access your funds, recover your PIN, or reverse transactions. You are in full control.
