# Mecanismos de Colateralização de Stablecoins

Mecanismos de colateralização de stablecoins lastreiam o valor de uma stablecoin com colateral, garantindo estabilidade de preço e confiança.

Mecanismos de colateralização de stablecoins mitigam a volatilidade cripto, atrelando o valor da stablecoin a um ativo estável, frequentemente o dólar americano. Eles bloqueiam colateral em smart contracts ou dApps. O colateral garante a redimibilidade pelo ativo atrelado. Tipos incluem: over-collateralization (ex: Dai usa crypto collateral), dynamic collateral ratios e multi-asset collateral frameworks. Componentes chave incluem price oracles, liquidation mechanisms e governance. Enquanto a over-collateralization reduz o risco, ela introduz ineficiência de capital e suscetibilidade a oracle failures e crowding risk durante liquidity crunches.
