With major financial players like PayPal launching their own stablecoins, such as PayPal USD (PYUSD), many people are curious about this type of cryptocurrency and how it functions. Stablecoins are digital assets designed to maintain a stable value by being pegged to another asset, like a fiat currency or gold.
Why Stablecoins Matter
Cryptocurrencies like Bitcoin and Ether offer significant advantages, such as the ability to send payments anywhere without relying on intermediaries. However, their prices are highly volatile, making them less practical for everyday use. Most people prefer knowing how much their money will be worth in a week, both for financial security and daily needs.
Stablecoins address this volatility by tying their value to more stable assets, such as the US dollar or gold. While fiat currencies also fluctuate over time, their day-to-day changes are generally less dramatic than those of cryptocurrencies.
How Stablecoins Maintain Stability
Stablecoins achieve price stability through various mechanisms, primarily by holding reserves of the underlying asset. Here’s a breakdown of the main types:
Fiat-Collateralized Stablecoins
These are the most common type. The issuer holds a reserve of fiat currency, like US dollars, to back each stablecoin unit. For example, $1 million in a bank might support one million tokens. This ensures that users can redeem their tokens for the underlying asset at any time.
Crypto-Collateralized Stablecoins
Instead of fiat, these stablecoins use other cryptocurrencies as collateral. MakerDAO’s DAI is a prominent example. Users lock up crypto assets in vaults to generate DAI tokens. Smart contracts manage the collateralization ratios to maintain stability.
Algorithmic Stablecoins
These rely on algorithms to control the supply of the stablecoin, burning or minting tokens to keep the price pegged. While innovative, this model has proven risky and has faced several high-profile failures.
Types of Collateral Used
Stablecoins use a variety of assets for backing:
- Fiat Currency: The US dollar is the most popular, but others like the Turkish lira are also used.
- Precious Metals: Some stablecoins are pegged to gold or silver.
- Cryptocurrencies: Ether and other digital assets serve as collateral for certain stablecoins.
- Other Investments: Commercial paper or corporate debt sometimes forms part of the reserves, as seen with Tether and USD Coin.
Popular Stablecoins Explained
Tether (USDT)
Launched in 2014, Tether is the largest stablecoin by market cap. It’s widely used for arbitrage opportunities and cross-border transfers. However, it has faced legal challenges over its reserve transparency.
USD Coin (USDC)
A collaborative effort by Circle and Coinbase, USDC is known for its transparency and regulatory compliance. It’s fully backed by dollar-denominated assets and offers open-source infrastructure.
DAI
Operating on the Ethereum blockchain, DAI is a decentralized stablecoin backed by crypto collateral. Its smart contract-based system aims to eliminate central authority but has encountered technical issues in the past.
Potential Drawbacks of Stablecoins
Despite their benefits, stablecoins come with risks:
- Counterparty Risk: If the entity holding the reserves fails or acts dishonestly, users may not be able to redeem their tokens.
- Centralization: Some stablecoins allow transaction freezes or reversals, contradicting the decentralized ethos of cryptocurrencies.
- Regulatory Scrutiny: Governments are increasingly examining stablecoins, which could lead to new restrictions.
