YesterdayĀ VisaĀ published a thought leader article onĀ automating blockchain paymentsĀ where digital currency is held in a self-custodial wallet. Recurring payments are more straightforward if the cryptocurrency is held in custody because the owner can instruct the custodian to execute the payments similar to a bank account. However, for self-custodied wallets, the Ethereum blockchain requires a private key to make a payment.
An analogy in banking is if you set up a recurring payment with a debit or credit card but had to enter the card security or verification code every time a payment is made. Thatās not practical for recurring payments.
At the same time, the concept of a public blockchain sending payments without your permission is startling. However, the solution is relatively simple: getting you to approve a list of recipients, so you donāt end up paying some random person. Visa refers to it as a new type of account contract, a delegable account.
Ethereum has an improvement proposal called account abstraction (AA) that does something similar but has yet to be implemented. Visaās methodology is implemented on the StarkNet layer 2 blockchain scaling solution.
Meanwhile,Ā VisaĀ has been active for years in the blockchain and crypto spaces and launched aĀ crypto advisory practiceĀ last year. It provides payment cards for numerous crypto exchanges and is involved inĀ NFT art for the FIFA World CupĀ with the Crypto.com exchange.
On the central bank digital currency front, it has won awards in two major CBDC challenges inĀ SingaporeĀ andĀ Hong KongĀ and is also active in BrazilāsĀ CBDC trials. Given its CBDC work uses Ethereum technology, it could also be considering these automated payments for CBDC applications. Two years ago, it proposed a solution forĀ offline CBDCĀ payments.
