Build on x402 and Settle

Web3 Transactions Instantly

The infrastructure layer for HTTP-native payments. Implement x402 protocol support and settle blockchain transactions in seconds with enterprise-grade reliability.

What You Get

x402 Protocol Support

Full implementation of the x402 HTTP payment protocol. Enable any HTTP endpoint to accept payments natively without external payment processors.

Instant Settlement

Transactions settle in seconds, not days. Leverage blockchain finality to provide immediate confirmation for both payers and payees.

Multi-Chain Support

Deploy on Ethereum, Base, Arbitrum, Polygon, and more. Choose the chain that best fits your latency, cost, and ecosystem requirements.

Smart Contract Integration

Pre-built smart contracts for common payment patterns. Escrow, streaming payments, subscriptions—all audited and ready to deploy.

Gas Abstraction

Users don't need to hold native tokens for gas. We sponsor transactions and settle costs behind the scenes for a seamless UX.

Developer SDKs

TypeScript, Python, and Go SDKs with comprehensive documentation. Get from zero to production in hours, not weeks.

Compliance Ready

Built-in support for transaction monitoring, reporting, and compliance workflows. Meet regulatory requirements without custom infrastructure.

High Throughput

Handle thousands of transactions per second. Our infrastructure scales automatically to meet demand during peak usage.
