Summary
Executive Summary This report presents the results of our engagement with Connext to review their NXTP protocol for crosschain transfers. The review was conducted over two weeks, from July 26 to August 6, 2021, by Heiko Fisch, David Oz Kashi, and Martin Ortner. A total of 25 person-days were spent. The off-chain code components were reviewed on a best effort basis considering the given time constraints. During the first week, we focused on both the on-chain components of the system and the router (TypeScript) component.
