CLI tool designed to generate language bindings for Stellar Soroban smart contracts.

stellar-contract-bindings

stellar-contract-bindings is a CLI tool designed to generate language bindings for Stellar Soroban smart contracts.

This tool simplifies the process of interacting with Soroban contracts by generating the necessary code to call contract methods directly from your preferred programming language. Currently, it supports Python and Java. stellar-cli provides support for TypeScript and Rust.

Installation

You can install stellar-contract-bindings using pip:

pip install stellar-contract-bindings

Usage

Please check the help message for the most up-to-date usage information:

stellar-contract-bindings --help

Example

stellar-contract-bindings python --contract-id CDOAW6D7NXAPOCO7TFAWZNJHK62E3IYRGNRVX3VOXNKNVOXCLLPJXQCF --rpc-url https://mainnet.sorobanrpc.com --output ./bindings

This command will generate Python binding for the specified contract and save it in the ./bindings directory.

Using the Generated Binding

After generating the binding, you can use it to interact with your Soroban contract. Here's an example:

Python

from stellar_sdk import Network
from bindings import Client  # Import the generated bindings

contract_id = "CDOAW6D7NXAPOCO7TFAWZNJHK62E3IYRGNRVX3VOXNKNVOXCLLPJXQCF"
rpc_url = "https://mainnet.sorobanrpc.com"
network_passphrase = Network.PUBLIC_NETWORK_PASSPHRASE

client = Client(contract_id, rpc_url, network_passphrase)
assembled_tx = client.hello(b"world")
print(assembled_tx.result())
# assembled_tx.sign_and_submit()

Java

public class Example extends ContractClient {
    public static void main(String[] args) {
        KeyPair kp = KeyPair.fromAccountId("GD5KKP3LHUDXLDCGKP55NLEOEHMS3Z4BS6IDDZFCYU3BDXUZTBWL7JNF");
        Client client = new Client("CDOAW6D7NXAPOCO7TFAWZNJHK62E3IYRGNRVX3VOXNKNVOXCLLPJXQCF", "https://mainnet.sorobanrpc.com", Network.PUBLIC);
        AssembledTransaction<List<byte[]>> tx = client.hello("World".getBytes(), kp.getAccountId(), kp, 100);
    }
}
