etherscan-src

⏬🚀 Fetch the most up-to-date sources of verified Smart Contracts (including proxy implementations) from Etherscan in seconds!

Usage

CLI

• Fetch the sources of a contract from an address and save it to sources/ContractName/:

npx etherscan-src 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984

• Note that if a standard proxy is detected, the proxy's implementation sources will be fetched instead:

npx etherscan-src 0x7Fc66500c84A76Ad7e9c93437bFc5Ac33E2DDaE9

• You can optionally provide a target directory path, an Etherscan apiKey (to bypass the default query rate limit), or specify a network on which to query the Smart Contract's source code (by name or chainId, decimal or hexadecimal):

npx etherscan-src --target sources/uniswap/ \
    --apiKey ... \
    --network polygon \
    0xb33EaAd8d922B1083446DC23f610c2567fB5180f

Install

npm install etherscan-src
