aptos-sdk 0.4.1

//! Example: Basic APT transfer
//!
//! This example demonstrates how to:
//! 1. Create an Aptos client
//! 2. Generate or load an account
//! 3. Fund the account using the faucet
//! 4. Transfer APT to another account
//!
//! Run with: `cargo run --example transfer --features "ed25519,faucet"`
