This is part 4 of the step-by-step tutorial to walk the reader through the development of a Minimum Viable Ethereum Mobile Wallet in React Native. I call it the Minimum Viable Wallet or MVW in short.

MVW's source codes can be found here.

In this part, I will explain the codes that lets me execute functions in a smart contract.

This is the last of the 4-parts tutorial.

This is part 3 of the step-by-step tutorial to walk the reader through the development of a Minimum Viable Ethereum Mobile Wallet in React Native. I call it the Minimum Viable Wallet or MVW in short.

MVW's source codes can be found here.

In this part, I will explain the codes that lets me create a new Ethereum Wallet account and how I secure my private key in the mobile device.

Tutorial Structure

This tutorial is a work in progress. When done, it will come in 4 parts.

This is part 2 of the step-by-step tutorial to walk the reader through the development of a Minimum Viable Ethereum Mobile Wallet in React Native. I call it the Minimum Viable Wallet or MVW in short.

In this part, I will describe how to build the app from it's source codes that you can find here.

Tutorial Structure

This tutorial is a work in progress. When done, it will come in 4 parts.

This step-by-step tutorial walks the reader through the development of a Minimum Viable Ethereum Mobile Wallet in React Native. It will be useful for folks who need a React Native boilerplate to base on to develop Ethereum-based blockchain apps.

Motivation

There are many Blockchain use-cases that calls for a private Blockchain network between a group of participants. One example is Project Ubin - a project initiated by the Monetary Authority of Singapore that tests the use of a private distributed ledger for clearing and settlement of payments and securities between banks. Another example is a private supply chain network where a group of suppliers, distributors and end users track goods as they move across the supply chain. 

This is the second of a 2-part article that explains the codes behind Smart Contract Explained by Demonstration. You may read part one here.

Background

I depend tremendously on the online Remix IDE when I write Solidity Smart Contracts. Once in a while, I run an Ethereum workshop where participants code with the Remix IDE too. So I shudder to think that on some unfortunate days, the online Remix IDE may be inaccessible.

This is the first of a 2-part article that explains the codes behind Smart Contract Explained by Demonstration and will be of interest to developers who want to learn how to code a Web3-based DApp to serve as front-end user interface to a Solidity Smart Contract. In particular, this article explains the ways to:

This article builds on the tutorial written by Michael Chan here. In his article, Michael demonstrated how to code a React.js Dapp that writes a file's IPFS hash to an Ethereum Solidity Smart Contract and stores the file in IPFS. Michael Chan's article is a great piece to follow if React.js is what you are seeking.

I have come to enjoy coding in Solidity because it offers so much in innovative features.I have written about the "_" modifier in a previous article. In this article, I wish to document what emit in Solidity does.
