Ecosystem USDT (Tether): Dominant USD Settlement Rail & Centralized Stablecoin Infrastructure $189.7B supply. ~$141B in US Treasuries. 58.7% stablecoin market share. The protocol-level analysis of crypto's dominant USD settlement rail — reserves, Tron dominance, freeze function, KPMG audit, MiCA delisting decoded.
Ecosystem A7A5: The Programmable Ruble Rail A7A5 is the ruble-pegged stablecoin powering post-sanctions trade. Issued in Kyrgyzstan, backed by Promsvyazbank, Tron-dominant. $100B+ in volume, 15% APY, 41K wallets — the programmable RUB rail for restricted economies.
Ecosystem Tron: The Rail Washington Can't Reach Tron carries roughly half of all USDT (~$88B) — the dollar rail for the emerging-market grey economy, beyond the GENIUS Act's reach. Yet Tether froze $344M and ISIS-K wallets on it in 2026: the uncensorable rail is censorable, by the issuer not the state. Cache256 on the USDT chokepoint.
