OP Open Payment Address Protocol
Local-first no tracking

Four-way contribution split

Keep contributions together

This protocol demo gives a collaboration project one canonical payment URL. Each contribution has four equal, fixed split legs representing EUR, USD, GBP and Bitcoin destinations.

Four equal demo destinations

The published record fixes four 25% recipient legs. The destination names below are protocol-demo annotations; the addresses and settlement details are synthetic and no payout is executed.

Canonical payment URL

https://openpaymentaddress.org/collaboration

A compatible payment app deterministically derives the published payment record from this URL: openpaymentaddress.org/.well-known/open-payment/record/L2NvbGxhYm9yYXRpb24 It verifies that record before presenting the contribution options for this project.
