Visa, the global payments giant, has been exploring how to accept USDC payments efficiently on the Ethereum blockchain. This initiative represents a significant step toward integrating cryptocurrency-based transactions into mainstream financial systems.
USDC Payments via Visa
Cuy Sheffield, Head of Crypto at Visa, revealed during the StarkWare Sessions 2023 in Tel Aviv that the company is actively researching ways to allow its clients to convert digital assets directly into fiat currency on its platform. Given Visa’s existing infrastructure for automating currency conversions—such as switching between US dollars and euros for cross-border transactions—integrating tokenized dollars like USDC could be a logical technical progression.
The goal isn’t necessarily to enable users to send USDC directly from a Visa card over the Ethereum network. Instead, Visa is exploring how to use incoming USDC transactions on Ethereum to power payments. While Visa will continue supporting traditional fiat transactions, the future might allow users to fund payments using USDC from an Ethereum wallet, alongside conventional bank account options.
These efforts are still in the internal testing phase. Visa is assessing the feasibility and security of such services. The fact that the company has a dedicated crypto division underscores its serious commitment to blockchain innovation.
Understanding USDC on Ethereum
USD Coin (USDC) is a stablecoin fully backed by US dollar reserves. Technically, it is an ERC-20 token issued on the Ethereum blockchain. Transactions involving USDC can occur directly on Ethereum or through Layer-2 scaling solutions like Polygon, Arbitrum, or Optimism.
USDC is widely used across decentralized finance (DeFi) applications on Ethereum. Although Tether (USDT) is more prevalent in terms of trading volume, USDC is often regarded as a more secure and transparent alternative due to its regulatory compliance and institutional backing.
Circle is the primary issuer of USDC, with Coinbase as a key partner. Being a publicly traded company, Coinbase adheres to rigorous legal and operational standards, which enhances trust in USDC. The stablecoin’s reserves consist of over 77% US government bonds and approximately 23% cash dollars, ensuring full collateralization.
USDC vs. Tether: Key Differences
Tether (USDT) remains the most widely used stablecoin by market capitalization, which stands at around $68 billion compared to USDC’s $41 billion. USDT also dominates in trading volume, often exceeding even Bitcoin on many exchanges.
However, USDT and USDC differ significantly in structure and perception. USDT is available on multiple blockchains, including Tron, which offers faster and cheaper transactions. In contrast, USDC is primarily native to Ethereum, though it has expanded to other networks.
Another critical distinction lies in regulatory compliance. While both stablecoins require know-your-customer (KYC) checks for initial acquisition, USDT is often perceived as offering greater transactional anonymity. Meanwhile, USDC is subject to stricter anti-money laundering (AML) controls due to its partnerships with regulated entities like Circle and Coinbase.
These regulatory safeguards make USDC more appealing to institutional players, whereas some users prefer USDT for its flexibility and broader accessibility.
Why Visa Chose USDC and Ethereum
Visa’s decision to test USDC on Ethereum stems from safety, regulatory compliance, and network reliability. With Circle and Coinbase as regulated US-based entities, USDC aligns better with Visa’s operational standards than USDT, which lacks equivalent oversight.
Ethereum’s robust security and decentralization make it a natural choice for high-value financial experiments. By avoiding less secure blockchains or unstable stablecoins—like Terra’s UST, which collapsed in 2022—Visa minimizes risk while exploring innovative payment solutions.

Visa vs. Mastercard in Crypto Adoption
Visa is not alone in embracing digital assets. Mastercard has also increased its involvement in the cryptocurrency space, signaling growing competition between traditional payment giants in blockchain adoption.
However, regulated companies like Visa must prioritize security and compliance—areas where many crypto-native tools still lag. Tether’s regulatory standing, for example, may not meet Visa’s stringent requirements. USDC, with its transparent reserves and compliance framework, currently stands out as one of the few stablecoins suitable for large-scale financial integration.
Crypto Payments via Debit Cards
It is already possible to use cryptocurrency with Visa or Mastercard debit cards through third-party providers, typically crypto exchanges. These cards require users to deposit crypto, which is converted into fiat currency when making transactions.
Visa’s new approach could streamline this process by allowing direct USDC deposits onto cards, with automatic conversion handled by Visa itself. This would reduce reliance on external exchanges and improve user experience. Key details—such as whether conversion occurs at the time of deposit or payment, and whether USDC withdrawals are permitted—are still under evaluation. What is clear is that Visa intends to maintain a 1:1 conversion ratio between USDC and the US dollar.
