Una Stablecoin It's a digital currency that is always worth almost the same, like 1 dollar or 1 euro. It is used to buy, sell or store money in the crypto world without worrying that it will rise or fall much in value as is the case with other cryptocurrencies. It's like having a digital version of traditional money, but on the blockchain.

Una Stablecoin It is a type of cryptographic token designed to maintain stable parity with an underlying asset, such as a fiat currency (USD, EUR), a commodity (gold) or a basket of assets. Its objective is eliminate the inherent volatility of traditional cryptocurrencies (such as Bitcoin or Ethereum), providing a unit of account, medium of exchange and store of most predictable value within the blockchain ecosystem.

There are several types of stablecoins depending on their stability mechanism:

1. Collateralized FIATs: backed 1:1 by traditional currency reserves in regulated banks or custodians. Ex. : USDC, USDT, EURC.
2. Crypto-collateralized: backed by cryptoassets locked in smart contracts, with overcollateralization to absorb volatility. Ex. : COME ON (backed by ETH, wBTC, and others).
3. Algorithmic: they use supply-demand algorithms and mechanisms to maintain parity, without direct asset support. Ex. : FRAX, AMPL.
4. Commodities-backed: linked to physical goods such as gold, oil or precious metals. Ex. : PAXG (gold), XAUT.

In terms of functionality, stablecoins are widely used in:

• Trading and Arbitration on exchanges (DEX and CEX).
• Cross-border payments and low-cost remittances.
• DeFi systems, such as collateral, loans, liquidity pools and yield farming.
• Asset tokenization as a stable unit of account.
• Volatility hedging crypto.

From a regulatory standpoint, stablecoins are under increasing scrutiny for their systemic impact, especially fiat-collateralized ones. Regulations such as MiCA in the EU and possible frameworks in the U.S. Department of State seeks to establish requirements on backup, transparency, liquidity and governance, differentiating between EMT (e-money token) and ART (asset-referenced token).
