The first eUTXO-based stablecoin, implementing the AgeUSD protocol. It is pegged to the US dollar and backed by ERG with a floating reserve ratio (400%-800%).

SigmaUSD is a groundbreaking algorithmic stablecoin that pioneered the AgeUSD protocol on the Ergo blockchain. As the first stablecoin built on the extended UTXO model, it demonstrates how decentralized finance can achieve price stability without relying on centralized reserves or trusted third parties.

The protocol maintains its dollar peg through a unique dual-token mechanism: SigmaUSD (the stablecoin) and SigRSV (the reserve coin). Users mint SigmaUSD by depositing ERG as collateral, while reserve providers mint SigRSV to absorb price volatility. The system maintains a floating reserve ratio between 400% and 800%, ensuring robust overcollateralization even during market stress.

What sets SigmaUSD apart from other stablecoins is its completely decentralized design with no liquidation risk for individual users. Price data comes from Ergo's trustless Oracle Pools, eliminating dependence on centralized oracles. The entire protocol runs on smart contracts verified on-chain, with transparent reserve ratios visible to anyone. This makes SigmaUSD an ideal stable unit of account for the Ergo DeFi ecosystem, enabling predictable value storage and transactions without counterparty risk.
