Building for Private Subnets

Writing applications for the Rayls Subnets is similar to any other EVM chain, however there are several important distinctions that we will walk through in the following subsections.

In addition to the technical reference in this guide, keep in mind that since Subnets are permissioned, you will need to have permission from a Subnet operator before you can deploy any smart contract into a Subnet.

Rayls Private Subnet Components

A Rayls Private Subnet is comprised of protocols, chains, tools, and SDKs.
