## What Is the Difference between an Algorithmic and a Fiat-Backed Stablecoin?

A fiat-backed stablecoin maintains its peg by holding equivalent reserves, such as US Dollars or short-term treasuries, for every coin issued. An algorithmic stablecoin, however, attempts to maintain its price peg through automated smart contracts that manage the supply.

It often uses a secondary, volatile cryptocurrency as collateral or a stabilization mechanism. Fiat-backed coins aim for 1:1 redeemability, while algorithmic coins rely on market incentives and code.

The former faces reserve quality risk, the latter faces design and execution risk.

## Glossar

### [Algorithmic Stablecoin](https://learn.greeks.live/area/algorithmic-stablecoin/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Resilience ⎊ Algorithmic stablecoins, particularly those designed with sustainability in mind, represent a novel approach to mitigating systemic financial risks inherent in traditional fiat-pegged assets.

### [Fiat-Backed](https://learn.greeks.live/area/fiat-backed/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Collateral ⎊ The concept of fiat-backed cryptocurrency or derivatives fundamentally rests on the provision of collateral, typically held by a custodian or escrow agent, to represent the underlying value.

This compelling geometry metaphorically represents the intricate settlement fabric underlying sophisticated digital asset exchange ecosystems. It illustrates the structural intersectionality of off-chain request for quote mechanisms interfacing with on-chain smart contract execution for complex financial instruments. The visual interplay suggests the dynamic relationship between base layer assets and layered synthetic instruments, akin to embedded options strategies within complex collateralized lending vaults. Understanding these interlocking structures is crucial for grasping capital efficiency across decentralized leverage utilization and monitoring oracle data feeds impacting delta hedging within high-frequency crypto derivative trading environments. The design hints at the systemic interdependency required for maintaining solvency in permissionless decentralized exchange operations."
