Knowledge Bases

The Ethereum ecosystem is a massive and talented open source community and has produced a pantheon of valuable developer resources over the past several years. With a platform like Kauri, the community is now even using the innovation of Ethereum itself to vet, curate, and store high-quality content. From in-person training to technical tutorials to research forums, the knowledge bases below offer a wide range of resources for developers of all levels.

Node infrastructure and instant access APIs make it easy for Ethereum developers to connect their applications to the blockchain. An Ethereum client refers to any node that is able to parse and verify the blockchain, its smart contracts, and everything in between. An Ethereum client also provides interfaces to create transactions and mine blocks which is the key for any Ethereum transaction.

Node Infrastructure

IDEs and Editors

IDE stands for Integrated Development Environment. IDEs and Editors are what you need to write and test software. They are software suites that consolidate basic tools that are required to start writing on Ethereum.

    A suite of tools to interact with the Ethereum blockchain in order to debug transactions.

  • dev portal atom logo


    An open source and usable text editor.

Smart Contracts

If you want to develop on Ethereum, you need to know how to write smart contracts. Solidity, Ethereum’s main smart contract language, is easier to learn if you already possess a good understanding of Javascript. You’ve probably used programming libraries before, and the ones below are no different. A smart contract library is the reusable piece of code for a smart contract which is deployed once and shared many times. If you are creating a tool, product, or application on Ethereum, you’ll also want to make sure your smart contract is in working order before deploying to the mainnet. These tools will help you build, test, and ship your code.


  • dev portal vyper


    A pythonic programming language for implementing smart contracts. Vyper is also currently beta software.

  • dev portal solidity

Testing and Deployment

  • dev portal waffle


    Waffle is a library for writing and testing smart contracts. Waffle is based on ethers.js.

  • dev portal microsoft

Ok, so you’ve finally built your dapp or smart contract. But how do you know it was set up correctly and is safe from hackers? The security tools below will help ensure that your code is safe and follows all Ethereum development best practices.

  • dev portal manticore


    A command line interface that uses a symbolic execution tool on smart contracts and binaries.

  • dev portal oyente


    An analysis tool for smart contracts. Oyente utilizes a symbolic execution tool that works directly with EVM byte code without access to the high level representation (e.g Solidity).

  • dev portal mythx


    A security analysis API for Ethereum smart contracts. MythX powers tools that bring security into the smart contract software development life cycle.


Public testnets on Ethereum offer a way for developers to test what they build without putting their creations on the main Ethereum network. You can obtain as much ETH as you want on testnets because testnet ETH doesn’t carry any monetary value. Similar to public testnets, local testnets are a place for you to test your software without pushing it public. Unlike public testnets, the local testnet software will only run on your computer/node and other users won’t be able to see it or interact with it. Below are the most used testnets to start testing on and links for requesting testnet ETH.

Public Testnets

  • dev portal kovan


    A proof-of-authority blockchain started by the Parity team. Test ether must be requested.

  • dev portal gorli


    Proof-of-authority cross-client testnet, synching Parity Ethereum, Geth, Nethermind, Pantheon, and EthereumJS. This testnet is a community-based project, completely open-source.

  • dev portal ropsten


    A proof-of-work blockchain that most closely resembles Ethereum and allows you to easily mine faux-Ether.

  • dev portal rinkeby


    A proof-of-authority blockchain started by the Geth team. Test ether must be requested.

Local Testnets

  • dev portal ganache


    Ganache is a personal blockchain for Ethereum development that developers can use to deploy contracts, develop applications, and run tests.


If you want to start developing dapps, you’ll need front-end development skills. Below are the most popular front-end interfaces that will help you turn your dapp from an idea to a live Ethereum mainnet application. If you’re interested in doing backend/protocol work on Ethereum, you should have significant experience with Go, Rust, Java, .NET, Ruby, or Python.
