NEAR StakeWars III - Challenge-16

Connect a node validator for sending notifications through Notifi.

Notifi Network is a notifications provider for web3. In this challenge, you will test yourself on using the Notifi API to communicate when your staking is going lower than seat price.

1. Get credentials for Notifi service

Using the Notifi network Discord we got the credentials:

2. Create the script for monitoring stake and seat price

The code will make an RPC call to the validators endpoint, and will:

  • Login to Notifi service.
  • Get the list of current validators.
  • Get the list of next epoch validators.
  • Calculate the next epoch seat price.
  • Calculate the next epoch max seat price for chunk only producers.
  • Get the current stake of this pool idtcn2.
  • Evaluate if we are validating, if we are above seat price and if wer are a chunk only producer.
  • Broadcast the message.

The code can be found in the ./scripts folder.

Must install and build it before running it:

cd ./scripts
node i
npm run build

3. Test it sending notifications

Run the script:

4. Check received emails

5. Add to crontab

Create a script to run it every hour run/notifi-stake.sh:

#!/bin/bash
cd ~/notifi-integration
node build/index.js

And finally add it to crontab:

# Notifi stake
0 */1  * * * sh /home/ubuntu/run/notifi-stake.sh
