## What is a Xai RPC Node?

Access gaming blockchain

A Xai RPC node provides applications with access to a blockchain purpose-built for Web3 gaming. Unlike general-purpose chains where gas fees and wallet complexity create friction, Xai enables gas-free player experiences and wallet abstraction, allowing gamers to play blockchain games without even knowing they're using blockchain technology.

### Why gaming needs dedicated infrastructure

Traditional blockchains fail for gaming due to **gas fees** (players won't pay for each action), **wallet complexity** (gamers won't manage private keys), and **throughput limitations** (games need high-frequency interactions). **Xai solves these problems** with gas-free transactions, seamless onboarding, and gaming-optimized infrastructure.

**Xai advantages:**

- **Gas-free gaming** — players pay nothing
- **No wallet friction** — play without crypto knowledge
- **High throughput** — handles gaming workloads
- **AAA partnerships** — real game studios building
- **Arbitrum security** — inherits L2 security
- **EVM compatible** — familiar development

### Layer 3 for gaming

Xai is a **Layer 3** — a blockchain built on top of Arbitrum (which itself is built on Ethereum). This layered approach enables Xai to optimize specifically for gaming while inheriting security from Arbitrum and Ethereum. Using **Arbitrum Orbit** technology, Xai customizes consensus, gas models, and execution for gaming use cases.

**Xai's Layer 3 architecture:**

1. Layer 1: Ethereum provides ultimate security
2. Layer 2: Arbitrum offers scalability and lower costs
3. Layer 3: Xai optimizes for gaming-specific needs
4. Games benefit from all three layers' advantages
5. Players enjoy gas-free, seamless experience

### Bringing AAA to Web3

Xai partners with **AAA game studios** to bring high-quality gaming to Web3\. By removing blockchain complexity from the player experience while giving studios powerful on-chain asset management, Xai enables the next generation of blockchain games that mainstream gamers will actually play.

This focus on user experience over crypto-native features positions Xai as infrastructure for gaming's blockchain future.

## Technical Documentation

Quick start for developers

### Supported RPC Methods

Xai supports all standard Ethereum JSON-RPC methods:

- **eth\_blockNumber** — current block number
- **eth\_getBalance** — XAI balance
- **eth\_call** — execute view functions
- **eth\_sendRawTransaction** — broadcast transactions
- **eth\_getTransactionReceipt** — transaction confirmation
- **eth\_getLogs** — event logs
- **eth\_gasPrice** — current gas price
- **eth\_estimateGas** — gas estimation
- **eth\_subscribe** — WebSocket subscriptions

### Code Examples

💻

#### JavaScript (ethers.js) — Xai Connection:

```
const { ethers } = require('ethers');

const provider = new ethers.JsonRpcProvider('https://rpc.crypto-chief.com/xai/YOUR_API_KEY');

// Verify we're on Xai
const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId); // 660279

// Get XAI balance
const balance = await provider.getBalance('0x...');
console.log('XAI Balance:', ethers.formatEther(balance));

// Interact with game NFT contract
const GAME_NFT = '0x...';
const nftABI = [
  'function mint(address to, uint256 tokenId) external',
  'function ownerOf(uint256 tokenId) view returns (address)'
];
const gameNFT = new ethers.Contract(GAME_NFT, nftABI, wallet);

// Mint game asset (gas-free for player!)
const tx = await gameNFT.mint(playerAddress, tokenId);
await tx.wait();
console.log('Game asset minted on Xai!');
```

💻

#### Python (web3.py) — Xai Setup:

```
from web3 import Web3

w3 = Web3(Web3.HTTPProvider('https://rpc.crypto-chief.com/xai/YOUR_API_KEY'))

print('Connected to Xai:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id)  # 660279
print('Latest block:', w3.eth.block_number)

# Gaming-optimized gas
gas_price = w3.eth.gas_price
print(f'Gas price: {gas_price}')

# Get XAI balance
balance = w3.eth.get_balance('0x...')
print(f'XAI: {balance / 1e18}')
```

💻

#### WebSocket — Monitor Gaming Activity:

```
const { ethers } = require('ethers');
const provider = new ethers.WebSocketProvider('wss://rpc.crypto-chief.com/xai/ws/YOUR_API_KEY');

// Monitor game transactions
provider.on('block', async (blockNumber) => {
  const block = await provider.getBlock(blockNumber);
  console.log(`Xai block ${blockNumber}: ${block.transactions.length} game txs`);
});

// Monitor NFT mints/transfers
const GAME_CONTRACT = '0x...';
const filter = {
  address: GAME_CONTRACT,
  topics: [ethers.id('Transfer(address,address,uint256)')]
};

provider.on(filter, (log) => {
  console.log('Game asset transfer on Xai:', log);
});
```
