Simple way to get contract source code verified on blockchain explorer.

Project description


This tool is designed to quickly download the code of open source contracts on the blockchain explorer.

The downloaded code maintains the file directory structure at the time of verification.

Supported Chain Platforms:



Get code by tx only supports:




pip install getSourceCode


getCode [-h] [-i INPUTFILE] [-o OUTPUTFOLDER] [-a ADDRESS] [-n NETWORK] [-k] [-p PROXY] [-t TXHASH] [-u] [-v] [--apikey APIKEY]

For example:

getCode -n bsc -a 0xb51eaa437AC67A631e2FEca0a18dA7a6391c0D07


getCode -n eth -a 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2 -p

The command execution result is as follows:

[root@hxzy test]# getCode -n bsc -a 0xb51eaa437AC67A631e2FEca0a18dA7a6391c0D07

Get code by tx only:

getCode -n eth -t 0x8dda3f4a1c4bbc85ed50d7a78096f805f2c9382e35800e42f066abaa7b17a71b -p

The address without the corresponding contract name is an unopened contractEOA.

Like this:

[root@hxzy test]#getCode -n eth -t 0x8dda3f4a1c4bbc85ed50d7a78096f805f2c9382e35800e42f066abaa7b17a71b -p

If there is a proxy contract, it will be displayed like this:

Proxy => Implementation:
0xff970a61a04b1ca14834a43f5de4533ebddb5cc8      0x1efb3f88bc88f03fd1804a5c53b7141bbef5ded8

In particular, the okex related chain needs apikey to use.

[root@hxzy test]#getCode -n okt -p -a 0x0eC4020F29faa430754f1dB07B66798d31006771
If you want to get the contract code of the okex link, you need to manually enter the api key.
Visit this link:
1. okt:
2. okb:
3. okt-testnet:

Follow the steps below:
1. Open the above link
2. Open the browser developer tool
3. Click the contract tab page on the browser
4. Find the request "contract?t="
5. X-Apikey in the request header of the request is the required apikey

For example:
getCode -p -n okt -a 0x38AB5022BEa07AA8966A9bEB5EF7759b715e4BEE --apikey LWIzMWUtNDU0Ny05Mjk5LWI2ZDA3Yjc2MzFhYmEyYzkwM2NjfDI4MDQzNDU3Mjc2NjY0OTI=

Parameter description:

optional arguments:
-h, --help       show this help message and exit
-i INPUTFILE     Input file path including contract addresses.
-o OUTPUTFOLDER  Choose a folder to export.
-a ADDRESS       A string including contract addresses.
-n NETWORK       Which network to get source code.
-k               Provide some blockchain explorer api keys.
-p PROXY         Use a proxy.
-t TXHASH        Get the relevant contract source code in the specified transaction.
-u               Check to see if a new version is available to update.
-v               Show version
--apikey APIKEY  The apikey required by the okex related chain.
