How to use this site

We recommend starting by reading chapters 3, 6, 7 and 8 of the short report for a non-technical overview of how Nexus works.

The rest of this site gives a more technical overview of Nexus, tailored at professionals in the payments industry. Each section is focussed on a particular role in the Nexus ecosystem:

• Payment Service Providers (PSPs)

• FX Providers (FXPs)

• Settlement Account Providers (SAPs)

• Instant Payment System Operators (IPSOs)

• Proxy lookup service operators (PLSOs)

The first section of each guide covers business and scheme-related aspects (eligibility, obligations, revenue models etc) while the second parts covers the technical integration between Nexus and the participant's systems.

There are also references to:

• Nexus APIs

• ISO 20022 messages used in Nexus

• Glossary and list of acronyms

This site is a live document, and will be regularly updated with the latest specifications as the project advances. Please see the change log for a summary of changes.

We welcome feedback and suggestions for improvement to the design of Nexus is welcome - please contact the Nexus team at [e-mail].
