Module contracts 

Ink! smart contract deployment and interaction

This module provides functionality for deploying and interacting with ink! smart contracts on Substrate-based chains.

Features

• Deploy compiled ink! contracts (Wasm)
• Call contract methods (read and write)
• Parse contract metadata
• Handle contract events
• Gas estimation for contract calls

Example

use apex_sdk_substrate::contracts::ContractClient;

// Deploy a contract
let contract = ContractClient::deploy(
    client,
    wasm_code,
    metadata,
    constructor_args,
).await?;

// Call a contract method
let result = contract
    .call("transfer")
    .args(&[recipient, amount])
    .execute(&wallet)
    .await?;
