How Stablecoins Maintain Their Peg
Different stablecoins use different mechanisms to stay close to their reference price. The three dominant designs are fiat-backed, crypto-collateralized and algorithmic.
Fiat-Collateralized Stablecoins
Fiat-backed stablecoins are issued by companies that hold a reserve of dollars, Treasuries or money-market instruments equal to the circulating supply. USDT and USDC are the largest examples.
Trust depends on the issuer's audits, banking relationships and willingness to honor redemptions at par. When the reserves are transparent and regulated, the peg is extremely tight.
Crypto-Collateralized Stablecoins
Crypto-backed stablecoins are minted against on-chain collateral — usually ETH or staked-ETH derivatives — held in smart contracts. DAI is the longest-running example.
They are over-collateralized to absorb volatility in the underlying asset, with automatic liquidation triggered when collateral ratios fall too low.
The result is a permissionless dollar that does not depend on any bank account, at the cost of some capital efficiency.
Algorithmic Stablecoins
Algorithmic stablecoins try to maintain their peg through supply expansions and contractions rather than direct collateral. Most early algorithmic designs failed under stress; newer designs blend algorithmic mechanics with partial reserves.
Hybrid Designs
Several modern stablecoins combine techniques — partial fiat reserves, partial crypto collateral, partial algorithmic supply control.
These hybrids try to capture the capital efficiency of algorithmic models while keeping a reserve buffer for stress events.
Yield-Bearing Stablecoins
A new generation of stablecoins distributes yield from the underlying reserves directly to holders, on-chain. They are dollar-pegged but accrue value through rebases or wrapper tokens.
Adoption has grown quickly because the underlying yields — US Treasuries, money-market funds — flow back to the end user rather than the issuer.
Why Use Stablecoins?
Stablecoins solve a real problem: moving dollar value across borders, exchanges and protocols faster and cheaper than the traditional banking system can.
Common Use Cases
Stablecoins are now embedded into almost every part of crypto and an expanding share of mainstream finance.
The most common use cases include:
- Trading and parking value between volatile positions.
- Cross-border payments and remittances at near-zero cost.
- Collateral and unit-of-account inside DeFi lending and trading protocols.
Beyond crypto-native use, stablecoins increasingly settle B2B payments and on-chain payroll for global teams.
Top Stablecoins to Know
USDT and USDC dominate by circulating supply and exchange volume, with DAI as the largest decentralized option. New entrants like PYUSD and yield-bearing tokens continue to gain share.

Risks to Watch
Even "stable" assets carry risks: issuer insolvency, banking failures, smart-contract bugs and regulatory changes can all cause temporary depegs.
The largest depeg events have always recovered, but they tend to last from minutes to days — long enough to liquidate leveraged positions denominated in the affected stablecoin.
How to Buy Stablecoins on Godex
Select the stablecoin you want, choose what you are paying with, enter the amount and destination wallet, then send funds to the generated deposit address. No account is required for standard swaps.
Once the source transaction confirms, the destination wallet receives the converted stablecoin automatically — you can then move it into DeFi, a payment channel or cold storage.
