🚀 Basic Operations
Essential operations like connecting to the network, creating accounts, and checking balances.
Connect to Neo Network
Establish connection to Neo N3 network and get blockchain info.
use neo3::prelude::*;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Connect to Neo N3 TestNet
let provider = HttpProvider::new("https://testnet1.neo.org:443")?;
let client = RpcClient::new(provider);
// Get blockchain information
let block_count = client.get_block_count().await?;
let version = client.get_version().await?;
println!("Current block height: {}", block_count);
println!("Node version: {}", version.useragent);
println!("Network: {}", version.network);
Ok(())
}
Create New Account
Generate a new account with private key and address.
use neo3::prelude::*;
fn main() -> Result<(), Box<dyn std::error::Error>> {
// Create a new account
let account = Account::create()?;
println!("Address: {}", account.get_address());
println!("Public Key: {}", hex::encode(account.get_public_key().encode_point(true)));
println!("Script Hash: {}", account.get_script_hash());
// Export private key (be careful with this!)
let private_key = account.get_private_key();
println!("Private Key: {}", hex::encode(private_key.as_bytes()));
Ok(())
}
Check Account Balance
Check GAS and NEO balances for any account.
use neo3::prelude::*;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let provider = HttpProvider::new("https://testnet1.neo.org:443")?;
let client = RpcClient::new(provider);
let address = "NXXXXxxxXXXxxxXXXxxxXXXxxxXXXxxx";
let script_hash = address.to_script_hash()?;
// Check GAS balance
let gas_token = GasToken::new(&client);
let gas_balance = gas_token.balance_of(&script_hash).await?;
let gas_decimals = gas_token.decimals().await?;
println!("GAS Balance: {} ({})", gas_balance, gas_decimals);
// Check NEO balance
let neo_token = NeoToken::new(&client);
let neo_balance = neo_token.balance_of(&script_hash).await?;
println!("NEO Balance: {}", neo_balance);
Ok(())
}
