About SBC

SBC (Stablecoin) is a fiat-backed stablecoin built for programmable global payments. Unlike general-purpose stablecoins focused on exchange liquidity alone, SBC ships developer infrastructure — ERC-4337 paymaster and bundler APIs, SBC AppKit for gasless smart accounts, and x402 HTTP micropayments designed for AI agents paying for APIs, data, and compute.

What we build

The SBC developer hub is the integration surface for builders. It publishes OpenAPI specifications, agent authentication guides, engineering blog posts, and live tooling references for MassPay, Swap, and paymaster RPC. SBC is live across multiple networks including Base, Radius, Solana, Canton, and others.

Who we serve

Application developers shipping gasless checkout, protocols integrating stablecoin settlement, payment platforms batching payouts, and AI agent builders implementing x402 micropayments. If you need agents to discover, authenticate, and pay for your APIs programmatically, SBC provides machine-readable docs at /llms.txt and /openapi.json.
