Stable has published a v2.0 white paper that recasts the USDT-focused layer-1 blockchain as stablecoin payment infrastructure for institutional investors, with planned use cases including AI agent payments, business-to-business settlements and cross-border transactions. The network uses USDT as its native gas token and primary payment and settlement asset, removing the need for users to hold a separate token for fees, and also supports PYUSD issued by PayPal. The paper keeps STABLE's total supply at 100 billion tokens, with about 18 billion, or 18%, in circulation at token generation and the remaining 82 billion assigned to a Universal Lock pool for staged release from December 8, 2027 through June 8, 2029, with full circulation expected by December 8, 2029 at the latest. A price-protection clause allows any unlock phase to be postponed by as much as nine months if STABLE's 30-day volume-weighted average price falls below $0.025 before a scheduled release date.
