Blockscan Tags

Checks Curate for contract tags and posts them to an endpoint. Works nicely with cron.

Note: At the time of publication, there is no endpoint that lets us check if a given tag was already posted, so we keep a local DB to avoid posting the same tag again. Losing this database means the tool will submit everything again.

Volta

This project uses volta.sh for node version management. See package.json for the version.

Running

Duplicate .env.example and fill the env variables. You can use network specific files such as .env.kovan and then yarn start:kovan.

Cron Job

1- In the project folder, vim script-mainnet.sh paste the following and save. 2- Paste the following:

#!/bin/bash

cd /home/ubuntu/blockscan-tags

PATH=/home/ubuntu/.volta/bin:$PATH

echo "Using volta version $(volta --version)"
echo "Using node version $(node --version)"
yarn start:mainnet

3- Give script execution rights chmod +x script-mainnet.sh. 4- Setup the cron job: crontab -e and add 0 * * * * cd ~/blockscan-tags && ./script-mainnet.sh >> output-mainnet.log 2>&1
