This ERC standardizes payment signaling for token transfers. It introduces a `Pa…yment` event for individual payments and an optional `Order` event for transaction-level context, and conventions for typed metadata payloads. The standard is designed to work across both native token integrations and settler-based flows, giving applications and indexers a common way to recognize payment intent and associated metadata across various architectures.

like the idea, although I think it can be polished. The standard should define a minimal interface for implementing the pay and payFrom functions.

I don’t understand the Metadata Payload Encoding; could you please elaborate on that? Why does it need to be in this EIP and not as an extension?

Left a few comments on the PR

Thanks, appreciate the feedback. I also replied on Github.

I did consider keeping metadata encoding as an extension to the ERC. But since each app/platform/protocol may need custom encoding, it felt more useful to define a small set of canonical fields within the spec, alongside extensibility. This provides clear guidelines for implementations while reducing ambiguity for indexers.

Understood, yeah, i think it has to be as minimal as possible
