Package Exports

etherscan-src
etherscan-src/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (etherscan-src) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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

yarn add etherscan-src
