Cryptocurrencies have become a notable feature of the financial world, offering fresh solutions to traditional financial systems. Among them, stablecoins have emerged as a vital component, providing stability and liquidity to the volatile cryptocurrency market. Two of the most popular stablecoins are USDT (Tether) and USDC (USD Coin). This article will explore the differences between USDT and USDC, looking into their features, uses, and implications for the broader cryptocurrency ecosystem. 

Introduction to Stablecoins

Stablecoins are digital assets pegged to stable, real-world assets like fiat currencies or commodities. Unlike other cryptocurrencies such as Bitcoin or Ethereum, stablecoins aim to minimize price volatility, making them suitable for everyday transactions and as a store of value.

What are USDT and USDC?

USDT, or Tether, is a stablecoin pegged to the value of the US dollar. It is issued by the company Tether Limited and operates on various blockchain networks, including Ethereum and Tron. The circulating supply of Tether (USDT) amounts to 110.56B tokens out of a total supply of 113.09B tokens as of April 29, 2024. 

USDC, on the other hand, is a stablecoin launched by Circle Internet Financial and Coinbase, also pegged 1:1 to the US dollar. USDC currently has 33.5 billion coins in circulation, with a maximum supply capped at 33.6 billion USDC as of April 29, 2024.

How USDC Works

USDC operates on the Ethereum blockchain and follows a transparent approach to reserve management. Circle and Coinbase regularly publish attestations from independent auditors to verify the backing of USDC tokens with US dollars held in reserve accounts.
