As a reminder, there is a W3C Payments API, currently proceeding along the W3C Recommendation track, which registers "payment handlers" in the browser, and selects one to complete a transaction: https://w3c.github.io/payment-handler/ The purpose of the payments API is to automate all data entry and handle choices related to common transactions on the Web. Payment requests will often ask for information that Bitcoin wallets have no current need to provide, such as a shipping address. If shipping options or other personally identifying information (such as an email address and a return payment address) are involved, then it is the chosen payment type's *handler* that is tasked with negotiating with the user how to reveal the supposedly necessary information. https://www.w3.org/TR/payment-request/#the-options-argument Although it may seem early for wallet makers to consider integration with a mere W3C Recommendation, it would not be early to choose the right architecture to build code on, given that this is in the works for the major browsers. Development can proceed even in browsers that have not implemented anything, through an HTML5 Javascript polyfill. A demonstration which includes payment in bitcoins is already available, although it leaves as an exercise for the reader exactly how the txid would be made known to the handler (whether manually input by paste buffer after copying from an external app, or returned through IPC): https://web-payments.io/ https://github.com/digitalbazaar/payment-handler-polyfill >From my brief inspection: not bad. I don't see anything in this spec that would preclude the workflow of a Bitcoin transaction, whether on-chain (with the seller's backend marking off confirmations) or using the Lightning Network. It even allows the seller to offer a discount on certain payment methods: https://www.w3.org/TR/payment-request/#dom-paymentdetailsmodifier _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
