Visa's head of crypto, Cuy Sheffield, has expressed his belief that Ethereum (ETH) is not a suitable option for small-value transactions due to its cost inefficiencies. Sheffield argues that ETH is not well-suited for frequent, low-value transactions due to its high transaction fees. In contrast, Solana (SOL) has emerged as a more cost-effective alternative for small transactions. Recent data indicates that 65% of stablecoin transactions on the Solana network are under $100, showcasing its suitability for small-value transactions. Sheffield's comments echo concerns raised by others in the industry regarding Ethereum's scalability and cost issues. As Ethereum continues to grapple with these challenges, other blockchains like Solana may gain a competitive edge in the realm of small-value transactions.
