Building a Python Client to execute cross chain transactions with William Chang

Today’s feature is brought to you by William Chang. William is a Senior Backend Engineer with 4 years of experience developing smart contract on various blockchain platforms. Recently, he has developed a Python SDK for a Cosmos-SDK based blockchain called Paloma.

What is PalomaPy?

PalomaPy is a Python Client Library to interact with Cosmwasm contracts on the Paloma blockchain.

The Paloma blockchain is a Cosmos SDK chain that enables you to send messages to any EVM chain.

Previously, developers could only use the Palomad application written in Golang to execute transactions on Paloma. 

Now, Python developers can use their native language to deploy, create, and execute jobs on Paloma. 

We want to make it easy for Python developers to build and deploy Cosmos applications to EVM chains with one click.

What’s your favorite feature PalomaPy provides?

My favorite feature from the PalomaPy Python SDK is the jobs scheduling API. 

Using the cross chain automation power of Paloma, you can create and schedule a job to execute on any EVM chain following on-chain parameters.

What kind of on-chain parameters? Things like:
- job id
- chain id
- time
- contract address
- abi
- payload

Give an example:

You can write a python script to mint a Bored Ape Yacht Club NFT on Ethereum Mainnet, executing on Tuesday at 10:07am EST, only if the gas is below .1 ETH.

Then for the fun of it, you can write a script to sell that same NFT when the floor price of the collection rises 10%. 

How can developers get started?

1. Download the PalomaPy library from Pypi and install the packages

2. Check out our Quickstart Instructions

3. Join the Paloma Python channel on our Discord and come tell us how we can improve the Paloma Python SDK for you
