In the wave of decentralized finance (DeFi), the price of various cryptoassets fluctuates violently, which brings great uncertainty to trading, lending, investment and other activities. Decentralized stablecoins came into being. With its unique mechanism, it provides a stable anchor of value in the volatile crypto world and becomes an indispensable and important part of the DeFi ecosystem. So, what exactly is decentralized stablecoins? How does it work? And what role does it play in the DeFi ecosystem?
A decentralized stablecoin is a cryptocurrency published based on blockchain technology. Its value is pegged to a specific asset or a basket of assets. It is designed to maintain a relatively stable price and avoid large fluctuations like Bitcoin, Ethereum and other cryptocurrencies. Unlike centralized stablecoins (such as USDT, USDC, etc., which are published and managed by centralized institutions), the publishing, circulation and management of decentralized stablecoins are completely based on decentralized protocols and smart contracts. There is no single control center, and the transaction records are open, transparent and immutable. For example, MakerDAO's DAI is a typical decentralized stablecoin that is generated by staking cryptoassets such as Ethereum and maintains a 1:1 anchor relationship with the US dollar, providing users with a stable store of value and a medium of exchange in the DeFi ecosystem.
The operating mechanism of decentralized stablecoins mainly maintains price stability through strategies such as collateral, algorithmic adjustment, and arbitrage. Take the stablecoin as an example, users need to over-mortgage cryptoassets (such as Ethereum) to smart contracts, and the contract generates a corresponding amount of stablecoins according to the value of the collateralized assets. When the price of the collateralized assets falls, in order to avoid liquidation, users need to replenish the collateral; if the price rises, users can redeem part of the collateral. The algorithmic stablecoin automatically adjusts the supply of stablecoins through smart contracts. When the price is higher than the anchor target, the supply is reduced; when it is lower than the target, the supply is increased to balance the market supply and demand and In addition, the arbitrage mechanism also plays an important role. When the market price of the stablecoin deviates from the anchor price, the arbitrageur will obtain the price difference by buying and selling the stablecoin, which prompts the price to return to normal. HashKey Exchange When providing users with DeFi services, pay attention to the operating mechanism of various decentralized stablecoins to help users understand their risk and return characteristics and allocate assets rationally.
Decentralized stablecoins are widely used in the DeFi ecosystem and are the foundation of many financial activities. In a decentralized exchange (DEX), stablecoins serve as a party to a transaction pair, providing users with a price-stable medium of exchange, which is convenient for users to exchange assets and reduce transaction costs; in a lending agreement, stablecoins can be used as collateral or as a borrowing currency. Users can borrow stablecoins against other assets for investment or daily transactions, and can also deposit idle stablecoins into the agreement to earn interest. In addition, in payment, cross-border remittance and other scenarios, decentralized stablecoins rely on the decentralized and efficient characteristics of blockchain to achieve fast and low-cost value transfer. HashKey Exchange follows the trend of the DeFi stablecoin market, continuously optimizes its services, and provides users with more convenient ways to use decentralized stablecoins. However, when using decentralized stablecoins, users should pay attention to smart contract vulnerabilities, mortgage asset price fluctuations, algorithm failure and other risks, and participate in related financial activities cautiously.
