This code snippet aims to show users how to easily deploy a new smart contract on Hedera network with Hedera Python SDK. Using a set of standard transactions, developers can easly and safely interact with Hedera network.
This code snippet was contributed by astrid-net.
After importing the hedera package into our file, the deployContract function uses it to deploy a smart contract. Hedera Python SDK has some standard functions that allow us to interact with the Hedera network. We use the operator keys to initialise client, and use that to sign and submit transactionsto the Hedera network. You can use any Hedera account as an operator; if you do not yet have one, you can create your own operator account on Hedera Portal.
We take the compiled bytecode output from solc (the Solidity compiler),
and save that in byteCode.
This bytecode is is then stored as a file using FileCreateTransaction,
and we obtain the fileId from the transaction receipt.
Subsequently the file is deployed as a smart contract using ContractCreateTransaction,
by specifying the same fileId.
