Paying transaction fees on the Ethereum blockchain is often deemed too complicated for the majority of individuals. This perspective is held by Visa and in a recent blog post, the company disclosed that it has concluded trials for a fresh method enabling users to cover gas fees using traditional currency through their credit cards. This major player in the credit card industry also said that blockchain technology could “shape the future of money movement”. This comes not many days after PayPal announced that they will launch their own stablecoin. Which is making it seem like other financial businesses does not want to miss out on how blockchain technology is going mainstream. 

Whenever a user engages in a transaction on the Ethereum network, they are required to pay a gas fee. This encompasses actions like sending and receiving ether (ETH), the native digital currency of the Ethereum blockchain. Visa expressed that overseeing an individual's ETH balance to accommodate these expenses is pretty big. According to Visa, simplifying this process could enhance the accessibility and user-friendliness of blockchain-driven transactions. 

In an effort to address this disparity, Visa suggests making use of Ethereum's ERC-4337, the current protocol that empowers smart contracts on the blockchain to serve as wallets through a technique termed "account abstraction." This approach would be complemented by a paymaster contract, which is a smart contract-based account capable of handling gas fees on behalf of the user. This innovative solution would empower users to utilize a Visa card for the direct payment of gas fees' associated expenses.
