Stacks Pay: A Payment Request Standard for Stacks Blockchain Payments

[dantrevino]

Stacks Pay is a proposed standard for wrapping transaction information in a standard way for easy sharing.

Love standardization!

Thanks for proposing, @dantrevino! We'll review on the Leather team and provide thoughts.

Great work @dantrevino

Overall looks good, happy to see you're putting this forward! I left a few small comments.

@human058382928 @r0zar @biwasbhandari these encoded URLs describe a Stacks transaction, might be something cool we can do there with @aibtcdev tooling!

How difficult is it to integrate into existing payment flows? E.g. compared to eth integration. Maybe something for the introduction.

Hey Dan 👋

Awesome work on this! I wanted to share some thoughts based on my experience building Stacks Invoice Generator, where I tackled invoice generation for STX and Stacks tokens without smart contracts. One of the biggest challenges I faced was QR code functionality.

Initially, I wanted users to scan a QR code and have it automatically open their wallet (Xverse/Leather) with all payment details pre-filled—similar to Bitcoin or Ethereum payment URIs (e.g., bitcoin:address?amount=0.1). However, Stacks doesn’t currently support a universal payment link format, so I had to settle for QR codes that only contain the recipient’s address, requiring users to manually enter the amount and memo.

I believe adding universal payment links for STX and tokens (e.g., stackspay:stx1abc...xyz?amount=100&token=STX&memo=Invoice123) would be a game-changer for the ecosystem. It would:
✅ Enable seamless integration between wallets and apps.
✅ Improve the user experience by eliminating manual data entry.
✅ Make STX payments feel as smooth as Lightning payments in Bitcoin.

Would love to hear your thoughts on this! Is this something that could fit into Stacks Pay?

QR codes are a core part of the experience i the proposal. Check out https://stackspay.org/ and the Merchant Section in the spec for details. The encoding also has the benefit of providing checksum so that users (stackpay parsers) can ensure that the QR codes have not been tampered with.
