ERC20 Token Development on RSK with OpenZeppelin and Web3.py

Reading Time: 7 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: 8 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 Contracts Development in RSK

Reading Time: 9 minutes

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 tied up to Bitcoin through a 2-Way Peg system, managed by the Federation Partners, that makes code execution possible. Instead of designing a new programming language for developing Smart-Contracts, they used Solidity, the same language that Ethereum uses. This has two benefits: not only programmers won’t have to learn a new skill but also contracts in the Ethereum network could be deployed in RSK without much effort, taking advantage of the vast market capitalization Bitcoin has.

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.

Multiplexing Online Web Wallets with Bitcore Wallet Service

Reading Time: 1

In Web Wallets Using Copay and Scalable Multi-Signature Web Wallets With Copay we explained how to multiplex Copay connections to form a single BitPay Insight server connection so you could easily scale an online web wallet service based on BitPay open source software. Copay has since been modified to use interesting new components: Bitcore Wallet Service (BWS) and […]

Web Wallets Using Copay

Reading Time: 2 minutes

Victor Gonzalez from CoinFabrik forked the Copay project and modified the code to facilitate the creation of online wallet services. Currently, the Copay project handles your wallet on your browser, desktop, and mobile devices but not on a Copay server. The new Bitcore Wallet Service does store your wallets on a server, but they are […]
