ERC20 Token Development on RSK with OpenZeppelin and Web3.py

Reading Time: 8 minutes

In my last article, I’ve shown you how to make a Solidity ERC20 Token for the RSK Mainnet, how to import and use OpenZeppelin libraries and contracts, and how to use Truffle to deploy and interact with our contract.

Although we succeeded in our quest and accomplished our objectives using Truffle, eventually this suite might present failures when you are sending transactions, deploying or managing accounts. In our case, while following the previous article instructions, I’ve had problems managing newly created accounts in Truffle and sending transactions.

ERC20 Token Development on RSK with OpenZeppelin

Reading Time: 9 minutes

In the last article, we have seen how to build an RSK node in our computer, select the proper network for development, configure Truffle to connect and deploy our future contracts, add accounts to our node and obtain funds to use them to pay the gas.

You should have now your node in the selected network fully synced, and at least one account with funds configured in the truffle and RSK node config files for our deployments.

In this article, we’ll be discussing deployment and interaction of Smart-Contracts over the RSK network. Our contract will be an ERC20 Token, based on the OpenZeppelin libraries, and we will deploy it directly into the Mainnet.

Introduction to Smart Contract Development in RSK

Reading Time: 9 minutes

Motivation These last years there has been growth in Smart Contracts development, predominantly in the Ethereum blockchain. Ethereum, being a different type of blockchain than Bitcoin, can execute concise lines of code inside its chain, a job that Bitcoin (specifically designed to send transactions easily) can’t do. Here is where RSK intervenes building a sidechain […]

Test Solidity Smart Contracts Using Travis CI

Reading Time: 2 minutes

Our smart contract development team is using Travis CI to integrate automated testing into GitHub repositories. This guide for this great tool will not go into detail about Travis CI itself, but rather explain how to automate tests for Solidity smart contracts. We will be using Truffle for running and building tests and Ganache to set up the network since Travis has built-in support for JavaScript and Node.js.
