RIF Relay Installation

Requirements

RSK Node

You need to have a running RSK node version IRIS-3.0.0 or higher.

Yarn

We use yarn version v1.22.0 for package management.

Installation instructions at Yarn’s site. Check the install by running yarn version.

Node & NPM

We use Node version v12.18.3.

We recommend the use of nvm and the .nvmrc file included at the root of this project, so you can install the correct node version through:

nvm use
nvm install

If you choose to use node without nvm, you can find installation instructions at Node’s site.

You can check the installation by running node -v.

Npx & Truffle

An important tool we use for interacting with the blockchain is Truffle version v5.0.33.

You can follow the installation guide in the official site.

We run all truffle commands with the prefix npx. This is to execute node packages using the project’s version.

Checking the install by running npx truffle version.

The configuration file is truffle.js. Please see Truffle’s documentation for details about this file and how to use it.

Docker

We recommend following the official documentation for installing Docker and keeping it updated.

You’ll need to install both docker as well as docker-compose.

Running on macOS

To run the project using Docker on a Mac, please follow these steps or the scripts and web apps will not work.

• Patch readlink The startup scripts assume that GNU’s readlink command is available. But MacOS ships with BSD’s readlink, which is incompatible with GNU’s version. So we must patch readlink. This can be done using Homebrew as follows:

brew install coreutils
ln -s /usr/local/bin/greadlink /usr/local/bin/readlink

After this step, you must make sure that your PATH variable gives priority to /usr/local/bin over /usr/bin. You can check this with which readlink, which should output /usr/local/bin/readlink. Alternatively try executing readlink -f ., if it works you’re ok.

Building the project

Clone the project. Then run the following from the project’s root directory to build it.

yarn install
yarn prepare

Deploy contracts Locally

We’ll use truffle for deploying contracts. Have an RSK node up and running in regtest mode and then execute the following on the project’s root folder:

npx truffle migrate --network rsk

After running this command you will see a summary of contracts on the terminal, something similar to this:

|===================================|============================================|
| Contract                          | Address                                    |

You’ll need to save this summary for later use.

Deploy contracts On Testnet

We’ll use truffle for deploying contracts.

npx truffle migrate --network rsktestnet

Disclaimer: to use testnet, you should have an unlocked account with funds or configure it in truffle.js.

These contracts have been deployed on Testnet. See here for their addresses.
