Open Payments
Open Payments is an open API standard that can be implemented by account servicing entities to facilitate interoperability in the setup and completion of payments for different use cases.
Everything you need to build on open, interoperable payments

The Interledger stack is open source, fully documented, and free to use. Whether you want to run a wallet, create a network node, or read the specs, this is where to start.
The protocols, the standards, the Open Payments API, and the tools built on them are all developed in the open. Anyone can read the code, run it, propose changes, and contribute.

Rafiki is open source software that provides an efficient solution for an Account Servicing Entity to enable Interledger functionality on its users’ accounts.
The Interledger Protocol (ILP) is an open, neutral protocol for transferring money based on TCP/IP, designed for sending packets of money across different accounting ledgers.
Create a test wallet, make a mock purchase, and simulate a full payment flow from request to approval. You can also test your own integrations on the Test Network (Testnet), an open Interledger network working with test money.
Interledger is developed in the open, and so is its roadmap. Track active work, upcoming milestones, and shipped features across the projects, from Interledger Pay to new remittance corridors and network integrations.
The stack gets better because people build with it and contribute back. There are many ways to take part, whatever your experience with open source.
Ask questions, share what you’re building, and talk directly with the people developing the stack.
Join us this October to collaborate on our open source projects.
Our team shares their thoughts and experiences on Interledger and the work that we are doing.
You can build on Interledger on your own, using the open documentation, repositories, test tools, and community. You can also build with support: the Interledger Foundation funds teams and institutions integrating the stack or implementing Open Payments through its grant programs.
