§Neo X
Support for Neo X, an EVM-compatible chain maintained by Neo.
§Overview
The neo_x module provides interfaces for interacting with Neo X, an EVM-compatible chain maintained by Neo. It includes:
- EVM compatibility layer for interacting with Neo X as an Ethereum-compatible chain
- Bridge functionality for transferring tokens between Neo N3 and Neo X
- Transaction creation and signing for Neo X
- Provider interfaces for connecting to Neo X nodes
This module enables seamless integration between Neo N3 and EVM-compatible ecosystems, allowing developers to leverage both blockchain environments.
§Examples
§Connecting to Neo X and getting chain information
ⓘ
use neo3::neo_clients::{HttpProvider, RpcClient};
use neo3::neo_x::NeoXProvider;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Connect to Neo N3
let neo_provider = HttpProvider::new("https://mainnet1.neo.org:443")?;
let neo_client = RpcClient::new(neo_provider);
// Initialize the Neo X EVM provider
let neo_x_provider = NeoXProvider::new("https://rpc.neo-x.org", Some(&neo_client));
// Get the chain ID for Neo X
let chain_id = neo_x_provider.chain_id().await?;
println!("Neo X Chain ID: {}", chain_id);
// Get the latest block number
let block_number = neo_x_provider.block_number().await?;
println!("Latest block number: {}", block_number);
Ok(())
}§Using the bridge to transfer tokens between Neo N3 and Neo X
ⓘ
use neo3::neo_clients::{HttpProvider, RpcClient};
use neo3::neo_protocol::Account;
use std::str::FromStr;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Connect to Neo N3
let neo_provider = HttpProvider::new("https://mainnet1.neo.org:443")?;
let neo_client = RpcClient::new(neo_provider);
// Create an account
let account = Account::from_wif("YOUR_WIF_HERE")?;
// Initialize the bridge contract
let bridge = NeoXBridgeContract::new(Some(&neo_client));
// Get the GAS token script hash
let gas_token = ScriptHash::from_str("d2a4cff31913016155e38e474a2c06d08be276cf")?;
// Deposit GAS from Neo N3 to Neo X
let neo_x_address = "0x1234567890123456789012345678901234567890";
let amount = 1_0000_0000; // 1 GAS
let deposit_tx = bridge.deposit(
&gas_token,
amount,
neo_x_address,
&account,
).await?;
println!("Deposit transaction sent: {}", deposit_tx.hash());
Ok(())
