ERC-7798: Tap to Pay

ERCs
,
1

This ERC defines a standard for contactless payment transactions that can allow for interoperable customer to merchant onchain payments, regardless of the wallets the customer and merchant are using.

Comprised of three parts:

  • A new Ethereum Provider JavaScript API method called requestContactlessPayment
  • An agreement on the payload for data exchange between the parties
  • An optional mechanism for relaying large JSON payloads using a backend relayer

How is this compatible with account abstraction?

3

This would just be a mechanism for signaling the intent of paying over NFC, the signing or account format is irrelevant for this specific standard

4

How do you pass the intention reference and further reconcile the payment with that intention?

We have created ERC-7699 for the ERC20 for that, but welcome any other suggestions.

Did this go anywhere?

I think there is a case for this type of payment system, and we also concluded that ERC-681 is the way it should be done due to mobile OS limitations.
