How to Run a Shield Server

Before installing a shield server, one needs to have NodeJS and Git installed on the system.

• The first step is to clone Muon’s repository hosted on Github. This is done through the following git command:

git clone [e-mail]:muon-protocol/light-shield-node.git

• Copy your Muon app's JS file to the root of the muon-apps directory.

• Rename the .env.example file to .env and then open it and set the values for SIGN_WALLET_ADDRESS and SIGN_WALLET_PRIVATE_KEY variables.

• Install required node modules in the root of the cloned repository by using

npm install

• For development, run the shield server by

nodejs server.js

For production, run the shield server using

pm2 start

NB1: It is recommended that projects use more than one Shield Server to prevent the halting of the system as a result of downing the Shield server.

NB2: A security risk that threatens MuonApps is that trusted 3rd party RPCs such as Infura, Ankr or The Graph may be vulnerable to hacks. To address this issue, Shield servers had better not depend on such RPCs for their input. Rather, they ought to run their own Ethereum, sidechains, and graph nodes.
