ergpy

A python-jvm wrapper for interacting with the Ergo blockchain.

Usage

• Requires Java 8 or higher to be installed on system

pip install JPype1

pip install ergpy

• There are helper methods created to do simple transactions
  • Please checkout the examples.py (on github) to see how to use them.
  • Simple Send is available
    • Allows sending ERG to one address or multiple addresses in ONE transactions
  • Get wallet addresses is available
    • This gives derivations of wallet addresses given the mnemonic
    • If specified 2, a list of two addresses will be printed in the console
  • Get Box Info is available
    • Given the index and address, the selected box will be printed
  • Send Token is available
    • Allows sending token(s) to one or multiple addresses
    • The token id paramter must be given as a 2D array
    • Remember that tokens/nfts are seen as the same when transacting with them
  • Create NFT is available
    • Allows creating NFTs
    • One mint is one transaction
    • There are helper methods as well to get the sha-256 hash required while minting
      • SHA256 caster
        • Put the hash as a string and this will be converted into bytes
      • String Hasher
        • Input a string and this will be converted into a hash (only for testing purposes)
      • File Hasher
        • Input the file name and the hash will be generateed
  • Create Token is available
    • Allows a token to be minted
  • Custom
    • A bit more customization is available using methods from appkit.py
    • To truly have custom transactions appkit.py must be edited

Github usage

git clone https://github.com/mgpai22/ergpy && cd ergpy

pip3 install -r requirements.txt

python -m stubgenj --convert-strings --classpath "ergo.jar" org.ergoplatform java

• If using an ide such as pycharm , make sure the root folder is ergpy
  • This allows code completion via stubgenj to work properly
• This method is recommended for developer as it allows for direction customizations in appkit.py

Roadmap

• This is the begining of python support for Ergo! Contributions are essential for this to continue.
• Ergoscript support.
• Better documentation and packaging (first time creating a package).
  • Would love some help with this!
