abstract: >-
  An open-source, backendless, no-fee TypeScript SDK (and MCP server) implementing
  the x402 "402 Payment Required" standard across 28 blockchains in 10 families
  (EVM, Solana, TON, Tron, NEAR, Sui, Aptos, Algorand, Stellar, and the XRP Ledger).
  Self-custodial: payments settle straight to your wallet, verified locally against
