Visa is using a proposal from Ethereum developers. It will allow automatic pre-scheduled payments from non-custodial crypto wallets
Visa has developed a blockchain-based autopay solution. A document published by this company details a new concept based on Account Abstraction (AA) technology from Ethereum developers. It will allow the implementation of automatic pre-planned payments using smart contracts in non-custodial users’ wallets.
Account Abstraction technology was proposed back in 2016. Since the core Ethereum network does not yet support AA. Therefore, VISA implemented its solution in StarkNet, a second-tier blockchain built on top of Ethereum blockchain. The account model in StarkNet just uses AA technology.
Whereas normal accounts check if a transaction is correctly signed for a specific address. With StarkNet, they simply verify that the transaction is coming from a given address. In addition, the introduction of Visa’s concept into this blockchain has not only enabled the deployment of a new auto-payment feature. But also increased transaction throughput.
Visa notes that it sees autopay as a key functionality that the existing blockchain infrastructure lacks. And it invites interested companies working in this area to work together on projects in the field of programmable payments.
Our experts note that payment companies from traditional financial industry this year began to actively develop projects related to blockchain and cryptocurrency. Also at the end of September, SWIFT and Chainlink oracle network announced joint work on a blockchain project. This project will allow traditional financial companies to conduct transactions on a platform that supports almost all blockchains.
