glin-contracts

Contract metadata, deployment, and interaction utilities for GLIN Network.

Overview

This crate provides comprehensive tools for working with ink! smart contracts on GLIN Network:

• Contract deployment: Deploy compiled contracts to the blockchain
• Contract interaction: Call contract methods and query state
• Metadata handling: Parse and work with contract metadata
• Event decoding: Decode contract events from blockchain
• Encoding utilities: SCALE encoding for contract calls

Usage

Add this to your Cargo.toml:

[dependencies]
glin-contracts = "0.1.0"
glin-client = "0.1.0"
tokio = { version = "1", features = ["full"] }

Example

use glin_client::{create_client, get_dev_account};
use glin_contracts::{deploy_contract, call_contract};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    // Connect to network
    let client = create_client("ws://localhost:9944").await?;
    let signer = get_dev_account("alice")?;

    // Deploy contract
    let result = deploy_contract(
        &client,
        &signer,
        "path/to/contract.contract",
        vec![], // constructor args
        0,      // value
    ).await?;

    println!("Contract deployed at: {}", result.contract_address);

    // Call contract method
    call_contract(
        &client,
        &signer,
        &result.contract_address,
        "transfer",
        vec![], // method args
        0,      // value
    ).await?;

    Ok(())
}

Features

• Metadata parsing: Extract ABI and constructor information from .contract files
• Type-safe encoding: SCALE encoding for contract arguments
• Gas estimation: Automatic gas limit calculation
• Event monitoring: Listen and decode contract events
• Error handling: Detailed error messages for contract operations

Contract Metadata

This crate works with ink! contract metadata format (.contract files), which includes:

• Contract ABI (messages, constructors, events)
• Contract WASM bytecode
• Type definitions (SCALE info)
