Remix IDE - Your first smart contract

The easiest place to start writing smart contracts in Solidity in within the online Remix IDE. Given it is an online IDE, no installation or development environment setup is required, you can navigate to the site and get started! Remix also provides very good tools for debugging, static analysis, and deployment all within the online environment. The source code used in this tutorial can be found here. Before we get started, a quick reminder of what we will be building: A dApp which will allow an

Truffle: Adding a frontend with react box

Earlier in the series, we took a look at how to setup Truffle and use it to compile, deploy and interact with our Bounties.sol smart contract. This article will walk through the steps required to add a simple react.js front end to our Bounties dApp so that users can interact with our smart contract using their web browser. Source code for this tutorial can be found here. Truffle Box Truffle boxes are helpful boilerplate code, pre-configured to help you get up and running quickly developing your

Understanding smart contract compilation and deployment

As discussed earlier in the series, when developing dApps, and especially writing smart contracts, there are many repetitive tasks you will undertake. Such as compiling source code, generating ABIs, testing, and deployment. Development frameworks hide the complexity of these tasks and enable you as a developer to focus on developing your dApp/idea. Before we take a look at these frameworks such as truffle, embark and populous, we’re going to take a detour and have a look at the tasks performed a

Truffle: Testing your smart contract

Earlier in the series, we took a look at how to setup Truffle and use it to compile, deploy and interact with our Bounties.sol smart contract. This article will walk through the steps required to write tests for our smart contract within the Truffle framework. Tests in Truffle projects can be written in Javascript or Solidity, however, this article will focus on the Javascript tests. Truffle uses the Mocha testing framework to provide an easy way to write tests in Javascript and uses Chai for as

Truffle: Smart Contract Compilation & Deployment

Intro Earlier in the series, we took a look at how to manually deploy and interact with our Bounties.sol smart contract on a local development blockchain. We also briefly touched on development frameworks which hide the complexity of these repetitive tasks and allow us to focus on developing dApps. This article will walk through the steps required to setup Truffle and use it to compile, deploy and interact with our Bounties.sol smart contract. You should see that this is a much easier process th

Full Stack dApp Tutorial Series - Intro

Intro In this series, well build a simple dApp (decentralised application).   Well introduce all the different pieces of the tech stack and tools you can use to build a dApp.   The dApp will simply allow any user to issue a bounty in ETH Any user with an Ethereum account can Issue a bounty in ETH with the requirements Any user can submit a fulfillment of the bounty with evidence The bounty issuer can accept a fulfilment which would result in the fulfiller being paid out Prerequisites Youre a sof

Embark: Testing Your Smart Contract

Earlier in the series, we took a look at how to setup Embark and use it to compile, deploy and interact with our Bounties.sol smart contract. This article will walk through the steps required to write tests for our smart contract within the Embark framework. Tests in Embark projects are written in Javascript. Embark uses the Mocha testing framework to provide an easy way to write tests in Javascript and uses Node.js for assertions. You can read more about testing in Embark here. Source code for
