Sigma.Money is a volatility Tranching on BNB Chain. Sigma.Money is a community-driven DeFi platform that lets users trade assets like BNB with up to 7x leverage and no funding fees. It uses partial liquidation to minimize full liquidations and is powered by bnbUSD, a stablecoin minted exclusively with BNB-related assets (e.g. BNB, slisBNB) as collateral. bnbUSD maintains its peg through mechanisms like a Stability Pool for arbitrage, stabilization fees on large positions, a redemption right for $1 worth of collateral, and protocol safeguards during depeg events. All activity is governed by the Sigma invariant, ensuring the value of all positions and bnbUSD always matches total collateral.
