What's the difference between USDC vs USDT?

Stablecoins play a crucial role in the cryptocurrency ecosystem, offering a safe haven from the volatility of other crypto assets. As high liquidity tokens, they are widely used on decentralized exchanges and are crucial for trading and hedging. Two leading stablecoins in the digital assets market are USD Coin (USDC) and Tether (USDT), both pegged to the U.S. dollar. In this blog post, we will delve into the key differences between USDC and USDT, focusing on their respective stablecoin issuers, transparency, and adoption.

Issuance and backing

USD Coin (USDC) is issued by Circle, a U.S.-based financial technology firm. It is an ERC-20 token that is backed by U.S. dollar reserves held in regulated U.S. financial institutions. The USDC issuer guarantees that for every USDC token minted, there is an equivalent U.S. dollar held in reserve, ensuring a 1:1 peg.

Tether (USDT), on the other hand, is issued by Tether Limited, a company connected to the Bitfinex exchange. Initially backed 1:1 by U.S. dollars held in reserve, USDT's backing now includes a mix of cash, cash equivalents, and USD currency assets. The composition of Tether's reserves has been a subject of debate, raising concerns about its stability.

Transparency and audits

Transparency is vital in fostering trust among liquidity users in the digital assets market. USDC stands out in this regard, as Circle regularly conducts audits by independent accounting firms to verify that the circulating supply of USDC is fully backed by U.S. dollar reserves. These audit reports are made publicly available, ensuring transparency and fostering confidence in the USDC peg.

Conversely, USDT has faced criticism regarding transparency and audits. While Tether Limited has released some attestations regarding their reserves, they have not provided the same level of transparency and regular audits as USDC. This has raised concerns among investors and the broader crypto community.

Company Headquarters

Given the differences in domicile, USDC and USDT are subject to different regulatory environments. USDC, issued by Circle, a U.S.-based financial technology firm, benefits from being subject to stringent American regulations. As a result, Circle operates within a well-regulated framework that inspires trust among investors and ensures compliance with U.S. laws.

On the other hand, USDT is issued by Tether Limited, a company connected to the Hong Kong-based Bitfinex exchange and its parent company, iFinex Inc. Founded in Hong Kong and registered in the British Virgin Islands, USDT may not face the same level of regulatory scrutiny as its U.S.-based counterpart. Here is an organization chart that from a NY AG filing:

Adoption and market presence

USDT was introduced in 2014 and has a longer history in the market, which has contributed to its larger market capitalization. As one of the earliest stablecoins, it became widely used for trading and settling transactions on various cryptocurrency exchanges. Its high liquidity and established presence made it a popular choice among users in the digital assets market.

On the other hand, USDC was introduced in 2018 by Circle and Coinbase, entering the market with a strong backing from reputable companies. Despite its relatively recent introduction, USDC has seen rapid growth in adoption, thanks to its transparency, regulatory compliance, and solid backing. As a result, it has become a popular alternative for those seeking a more transparent and regulated stablecoin in the rapidly evolving world of cryptocurrencies.

While USDT maintains a larger market presence and high liquidity, USDC's growing adoption and strong foundations make it a formidable contender in the digital assets market.

Regulatory compliance

USDC is widely regarded as a more regulated and compliant stablecoin compared to USDT. Circle adheres to strict regulatory guidelines and follows U.S. financial regulations, which has played a significant role in USDC's growing adoption.

USDT, on the other hand, has faced scrutiny from regulators and has been subject to legal actions. Concerns over Tether Limited's reserve backing and transparency have led to questions about its regulatory compliance.

A recent development that has impacted the use and perception of Tether (USDT) is the announcement by the Canadian Securities Administrators (CSA). The CSA issued guidance stating that stablecoins like USDT could be considered securities under certain circumstances, which led to increased scrutiny and regulatory pressure.

In response to the CSA's announcement, many Canadian cryptocurrency exchanges decided to delist USDT from their platforms. This move was driven by concerns that continuing to list USDT could potentially violate securities regulations, given the lack of transparency surrounding Tether's reserve backing and its history of legal challenges.

This development has further differentiated USDC and USDT, as USD Coin (USDC) has not faced similar delistings. USDC's strong regulatory compliance and transparency have enabled it to maintain its listing on various exchanges, both in Canada and globally, without raising concerns from regulators. 

The CSA requires that trading platforms permit these tokens to be sold or bought only if their reserves consist of highly liquid assets such as cash. These reserves should also be held with a qualified custodian and should be subjected to monthly reviews by independent auditors. The notice from the CSA included a recognition of use cases for stablecoins such as payments and volatility hedging. However, the CSA still considers stablecoins riskier than fiat currency.

Networks and Cross-Chain Compatibility

Another point of comparison between USDC and USDT is the range of networks and blockchains they operate on. While both stablecoins share some common networks, such as Ethereum and Solana, there are differences in their cross-chain compatibility.

USD Coin (USDC) was initially launched as an ERC-20 token on the Ethereum blockchain. However, recognizing the need for interoperability and scalability, USDC has expanded its presence to other networks, including Algorand, Stellar, Solana, and Avalanche, among others. This expansion allows users to take advantage of faster transactions, lower fees, and improved network capabilities on various blockchains.

Tether (USDT) also began its journey as an asset on the Bitcoin blockchain using the Omni Layer protocol. Over time, it expanded its reach to other networks, including Ethereum, Tron, EOS, Solana, and Binance Smart Chain. This extensive cross-chain compatibility enables users to access USDT across multiple platforms, providing flexibility and ease of use in the ever-growing digital assets market.

Although both USDC and USDT operate on a variety of networks, their specific cross-chain compatibility differs. Users should consider the networks they primarily engage with when choosing between these stablecoins to ensure seamless integration and optimal performance.


Both USDC and USDT offer users the stability of the U.S. dollar in the volatile world of cryptocurrencies. However, the key differences between the two lie in their issuance, transparency, and regulatory compliance. USDC stands out as a more transparent and regulated option, backed by reputable institutions, while USDT maintains a larger market presence. When choosing between USDC and USDT, consider your priorities in terms of stability, transparency, and compliance to make the best decision for your needs.
