About STABLE
Stable is a Layer 1 blockchain purpose-built for stablecoin payments, with USDT as the native gas token. The network eliminates dependence on volatile gas tokens, enabling ultra-low fees and sub-second settlement for dollar-denominated transfers. StableChain is designed to exceed 10,000 TPS with predictable transaction costs for enterprise-grade payment flows. The company has raised $28M in seed funding from Bitfinex, Hack VC, Franklin Templeton, Castle Island Ventures, and other major investors. PayPal Ventures also made a strategic investment to bring PYUSD onto StableChain. The mainnet launched in December 2025 with day-1 partners including PayPal, Curve Finance, USDT0, Transak, and WalletConnect
