Key Takeaways
- Every circulating USDT and USDC should be backed by an equivalent amount of USD cash and cash equivalents.
- Both USDT and USDC are widely adopted but serve different purposes. USDT is the most traded cryptocurrency by 24-hour volume, while USDC is perceived as a safer store of value due to its annual audits.
USDT and USDC are the two largest fiat-backed stablecoins by market capitalization. They offer lower volatility compared to native cryptocurrencies by pegging their value to fiat currencies, providing traders with a stable medium for transactions and value storage.
What Are Fiat-Backed Stablecoins?
The earliest stablecoins were backed by cash reserves. Here's how they work: fiat currency is locked in a protocol, and an equivalent amount is minted on a blockchain via smart contracts. These stablecoins can be redeemed for the original fiat currency. Redemptions involve burning the equivalent tokens through a controlled process to maintain the peg. This strategy has been highly successful and adopted by projects like USDT and USDC.
Fiat vs. Stablecoins
Fiat-backed stablecoins are tokenized versions of fiat currencies but with expanded utility. They operate on blockchain technology, enabling permissionless and borderless use. Unlike traditional fiat, these stablecoins can be transferred globally without stringent international transfer processes and traded on centralized and decentralized exchanges (DEXs).
