End-to-end Radius Network development playbook. Stablecoin-native EVM with sub-second finality. Uses plain viem (defineChain, createPublicClient, createWalletClient) for all TypeScript integration. wagmi for React wallet integration. Foundry for smart contract development and testing. Also covers Hardhat/ethers.js compatibility and EIP-7966 synchronous transactions. Micropayment patterns (pay-per-visit content, real-time API metering, streaming payments), x402 protocol integration, Radius x402 facilitators (Permit2 + EIP-2612), stablecoin-native fees via Turnstile, ERC-20 operations, event watching, production gotchas, and EVM compatibility differences from Ethereum.
Integrate x402 HTTP payment protocol on Radius. Use when the user wants to: monetize an API with per-request micropayments, add HTTP 402 payment gating to endpoints, consume a paid x402 API, sign x402 payment headers, integrate with a facilitator service, implement EIP-2612 permit + Permit2 payment signing, build pay-per-call services on Radius using SBC token, or set up x402 middleware. Covers both server-side (protect your endpoints with payment gating) and client-side (sign and pay for x402-protected endpoints). Use viem for app code signing, or Foundry cast for one-off CLI payment access.

Request testnet or mainnet tokens from a Radius Network faucet. Use when the user says "fund my wallet", "get testnet tokens", "get mainnet tokens", "drip SBC", "use the faucet", "get test funds", "fund my wallet on mainnet", "get SBC on mainnet", or needs tokens on Radius Testnet or Mainnet to start developing or testing.
