Remix as code viewer

Through Etherscan

Verified contracts on Etherscan can be viewed in Remix by making a simple change to the URL. Mostly for a mutiple part contract verification, Remix provides a quick way to load all the contracts.

A typical Etherscan URL for a contract address looks like this:

https://etherscan.io/address/0xdac17f958d2ee523a2206206994597c13d831ec7

In the URL, change etherscan.io to remix.ethereum.org

https://remix.ethereum.org/address/0xdac17f958d2ee523a2206206994597c13d831ec7

and reload. It will fetch the contracts verified on Etherscan.

Contracts verified on Ethereum mainnnet and on other test networks (Ropsten, Rinkeby, Kovan & Goerli) will be loaded in respective directories under etherscan-code-sample workspace.

Tihs works for Etherscan testnet URLs https://ropsten.etherscan.io, https://goerli.etherscan.io/ etc. If they are similarly updated, contracts will be loaded in Remix.

Through GitHub

Solidity files in GitHub can be loaded on Remix with a similar tweak. For a file with URL like:

https://github.com/ethereum/remix-project/blob/master/apps/remix-ide/contracts/app/solidity/mode.sol

change github.com to remix.ethereum.org like:

https://remix.ethereum.org/ethereum/remix-project/blob/master/apps/remix-ide/contracts/app/solidity/mode.sol

and reload. It will open the same file in Remix IDE.
