What is
Liquidity Pool?
Smart contract holding paired tokens that enables decentralized trading on AMM exchanges.
Liquidity pools are smart contracts containing reserves of two or more tokens. Traders swap against the pool rather than matching with counterparties. Liquidity providers deposit tokens and receive LP tokens representing their share, earning a portion of trading fees.
Key Points
- Contains paired tokens (e.g., ERG/SigUSD)
- Enables instant trades at any size
- LPs earn share of trading fees
- LP tokens represent pool share
- Deeper pools = less slippage
- Risk: impermanent loss if prices diverge

What is SigmaUSD and how does it work?
SigmaUSD is Ergo's algorithmic stablecoin, pegged to USD and backed by ERG reserves. It uses the AgeUSD protocol: users mint SigUSD by depositing ERG, while SigRSV holders provide reserve backing and absorb volatility. The reserve ratio (400-800%) ensures stability. No centralized issuer, no bank accounts - pure crypto collateral.
