Color Mint app using Truffle box and RSK network

Create an NFT to represent our collectible color tokens.

In this tutorial, you will learn about blockchain programming from scratch by building a fully decentralized application (DApp), step by step. You will also learn how to create your own collectable token on the RSK blockchain network using the Truffle framework, Open Zeppelin (OZ) libraries, and build a front end with React, using create-react-app.

You will be able to create new color tokens and claim them so that they can be held in a digital blockchain wallet.

Get gas price

curl https://public-node.testnet.rsk.co/2.2.0/ -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_gasPrice","params":[],"id":1}' > .gas-price-testnet.json

Truffle console

Truffle Console connected to RSK network Connect to RSK regtest (local node)

# for local node
truffle console
# for testnet
truffle console --network testnet

# get last block number
(await web3.eth.getBlockNumber()).toString()
# get network id(for local node network id is 33, for testnet network id is 31)
(await web3.eth.net.getId()).toString()
# get addresses
const accounts = Object.keys(web3.currentProvider.wallets)
accounts
# save account addresses to the file .accounts
await require('fs').promises.writeFile('.accounts', accounts.join('\n'))
# check balance for the first account
(await web3.eth.getBalance(accounts[0])).toString()
# exit truffle console
.exit
