Deploy

Web3 SDKs support to interact with Smart Contract via contract instance, not low-level transaction.

Import extend from web3py_ext to extend web3 to kaia web3

Import necessary utils

Load an account from private key

Create a Web3 instance with the specified kairos testnet URL

Also, you can change the provider URL from kairos to quicknode.

Define an account list as a list type to use middleware

If you want to automatically sign and send when using transact function, use construct_sign_and_send_raw_middleware

These are the contract that is compiled into bytecode and will be deployed to the Kairos testnet

Initialize a Web3 contract instance with bytecode and ABI

Set the contract bytebode and abi. You can get the bytecode and abi after compiled in remix or solc compiler

Deploy the smart contract by sending a tx. This automatically sign and send the tx that include constructor call data

Wait for the transaction receipt
