Visa's Solution for Simplifying Crypto Gas Fee PaymentsWritten by VanBreaking barriers in the volatile world of digital currencies, financial giant, Visa, is fine-tuning a novel mechanism that enables customers to pay on-chain gas fees through their Visa cards.Gas fees — the charge for conducting transactions on the Ethereum blockchain — can be an obstacle for both experienced and novice crypto enthusiasts.Mustafa Bedawala, a dedicated product manager at Visa, stressed the challenges users tackle when keeping track of Ether balances solely for gas fee coverage in their cryptocurrency wallets.Typically, users have to follow a complex process, buying Ethereum (ETH) and subsequently transferring it to a virtual wallet to cover gas fees, which could be daunting for brand-new users and an inconvenience for seasoned crypto-wallet owners.The Dawn of Visa's SolutionVisa's pioneering solution uses the ERC-4337 standard of Ethereum and a smart contract known as the "Paymaster". This innovative combination paves the way for off-chain gas fee settlements.Allowing us to delve into their clever mechanics, the process begins with a user initiating an Ethereum transaction through their wallet. The gas fee is then calculated and directly charged to the user's Visa card. Instead of using ETH from the wallet, the fee is sent to Visa through Cybersource.Once a digital signature is validated and attached by the wallet, it is sent to the Ethereum network where the Paymaster covers the gas fee.Eliminating ComplexityThis proficient system eradicates the need for users to keep ETH specifically for fee payments, smoothing out potential friction points for blockchain users. By this, Visa ensures a seamless transaction process for its tech-savvy clientele.To ensure its feasibility, Visa tried this unique concept on the Ethereum Goerli testnet, successfully waving off the necessity for ETH through the Paymaster.Widening OpportunitiesVisa's approach not only streamlines transactions; it opens avenues for merchants and decentralized applications, thereby enhancing customer experiences. It also introduces possibilities for gas fee payments via Visa cards.This year, Visa initiated trials of converting digital assets into fiat payments on the Ethereum blockchain, with a goal to mirror its current foreign currency exchange procedures. This falls in line with its broader ambition to excel in worldwide settlements involving both traditional and digital currencies.FAQs1.
