Radius is stablecoin-native settlement infrastructure for the agentic internet. It settles machine-to-machine micropayments at the scale of API calls, paid content, and streaming compute. 2.8M+ TPS tested, linear scalability, sub-second finality, near-zero transaction costs, EVM-compatible execution, stablecoin fees, and no native token.
Radius is built for agentic commerce: per-request API billing, HTTP-native x402 payments, pay-per-visit content, and streaming payments. Developers can use standard Ethereum tooling - Solidity, Foundry, viem, wagmi, ethers.js, and JSON-RPC - while paying fees in stablecoins instead of volatile gas tokens.
- Radius now has first-party x402 facilitator infrastructure for HTTP 402 payments on Radius mainnet and testnet.
- Radius x402 supports Permit2 settlement, EIP-2612 gas sponsoring,
/supported,/verify,/settle, and/healthfacilitator endpoints.
