# TESOURO
Etherfuse (TESOURO) is a blockchain-native stablebond that acts as a tokenized representation of real-world sovereign debt, specifically Brazilian Letras do Tesouro Nacional (Brazilian government treasury bonds). It is designed to combine the regulatory compliance and security of traditional finance (TradFi) with the speed, transparency, and liquidity of decentralized finance (DeFi). Issued by Etherfuse, a fintech platform focusing on tokenizing sovereign debt primitives, TESOURO provides investors with exposure to real-world government-backed asset yields while remaining fully composable across multiple blockchain networks.
#### **`Official Site:`**
**TESOURO** integrates institutional-grade government debt with blockchain infrastructure, enabling an asset asset class that looks like fiat, acts like a bond, and moves like crypto. Each token is 1:1 backed by underlying short-term sovereign bonds held securely in regulated institutional custody. This structure offers full transparent oversight, supported by regular third-party compliance verification and weekly independent attestations. Deployed across multiple major chains, TESOURO allows individuals, fintechs, corporate treasuries, and remittance providers to park capital, access underlying yields through price appreciation up to redemption, or use their positions as stable collateral across various DeFi applications.
