What is Remix?

Remix is a suite of tools to interact with the Ethereum blockchain in order to debug transactions, stored in this Git repository. A Remix transaction Web debugger is available here, and its source code is part of this repository.

The Remix IDE is an IDE for Solidity dApp developers, powered by Remix. The Remix IDE repository is available here, and an online version is available at https://remix.ethereum.org.

How to use Remix

Prerequisites

To use Remix tools, you'll need to connect to an Ethereum node. You can do that using the Mist browser, or by connecting to your local Ethereum node (geth, or eth). Note: connecting to geth does not work through https.

• Using geth: geth --rpc --rpcapi 'web3,eth,debug' --rpcport 8545 --rpccorsdomain '*'.

• Using eth: eth -j --rpccorsdomain '*'

DO NOT DO EXECUTE THESE COMMANDS IF geth/eth STORES YOUR PRIVATE KEYS, as any external system might be able to access your node's RPC server!

Those commands will run the RPC server on localhost:8545, which is the default URL that Remix will connect to. This instance should only be used for debugging purposes. Never use features that could have an impact on your keys: do not unlock any keys, do not use this instance together with the wallet, do not activate the admin web3 API.

Run the debugger

See here how to install, run and use the debugger locally.

Remix Modules

Remix is built out of 4 different modules:

• remix-solidity provides Solidity analysis and decoding functions.
• remix-lib
• remix-core is a utility package, providing high-level abstractions to work with the Ethereum VM.
• remix-debugger contains the debugging webapp.
