## Create the smart contract for token ERC 1155 by python

To create the contract itself, you can use [OpenZeppelin Contracts Wizard](https://docs.openzeppelin.com/contracts/5.x/wizard)

You can select the token type through the bookmarks in the wizard, and select the contract features through the menu on the left.

We will get something like this code:

[](../_media/examples/zencode_cookbook/ethereum/zen1155_oz501.sol ':include :type=code gherkin')

We take the source codes of the contract from the repository [openzeppelin-contracts](https://github.com/OpenZeppelin/openzeppelin-contracts)

In the contract, we replaced relative paths @openzeppelin with the path in the current directory. To do this, we copied the directory with contracts inside the working directory.

To deploy a contract we use a script:

We add option "evmVersion": "paris" for support stable version of geth Ethereum Virtual Machine (EVM).
May by your location of SmartContract OpenZeppilin repo different from allow_paths="/root/5.0.1/". So you need change that.

[](../_media/examples/zencode_cookbook/ethereum/doc_deploy_contract_erc1155_oz501.py ':include :type=code gherkin')

You will also need an environment file .env

GETH_RPC_URL=http://example.com:8545

The ID of Ethereum Network

NETWORK_ID=1337

The password to create and access the primary account

ACCOUNT_PASSWORD=My_pass

For mint ERC1155 token, you can also use the sample:

[](../_media/examples/zencode_cookbook/ethereum/doc_mint_erc1155_oz501.py ':include :type=code gherkin')

This script also contains examples for a clear understanding of the need for a digital signature for each new token mint.
