## What is a Flare RPC Node?

Access blockchain-native data infrastructure

A Flare RPC node provides applications with access to Flare's unique data-acquisition protocols alongside standard blockchain operations. Flare enables developers to build applications that rely on trustless price feeds, cross-chain data, and Web2 API access without centralized intermediaries.

### What makes Flare unique

Unlike traditional blockchains that require external oracles for off-chain data, Flare builds data acquisition directly into its consensus layer. The Flare Time Series Oracle (FTSO) and State Connector protocols provide decentralized, trustless access to price feeds and cross-chain information, enabling entirely new categories of DeFi applications.

**Flare advantages:**

- **Native oracles** — FTSO provides decentralized price feeds on-chain
- **Cross-chain data** — State Connector verifies external blockchain states
- **No oracle fees** — data acquisition built into protocol
- **EVM compatible** — full Solidity and Ethereum tooling support
- **Fast finality** — 1.8s blocks with quick confirmations
- **Multi-chain focus** — native integration with non-smart contract chains

### Flare's data protocols

**FTSO (Flare Time Series Oracle)** is a decentralized price oracle where independent data providers submit price data, which is aggregated through weighted median to produce trustless price feeds for assets like BTC, ETH, XRP, and more.

**State Connector** enables smart contracts on Flare to verify events and state from external blockchains (Bitcoin, Dogecoin, XRP Ledger) in a decentralized manner, enabling trustless cross-chain applications.

**How Flare works:**

1. Data providers submit price feeds and proofs to Flare
2. Validators aggregate data through consensus mechanisms
3. Smart contracts access verified data on-chain without fees
4. State Connector proves external blockchain events
5. Applications build on trustless, decentralized data

### RPC access methods

**HTTPS endpoints** handle standard EVM operations plus Flare-specific calls for FTSO data, State Connector proofs, and cross-chain verification.

**WebSocket endpoints** enable real-time subscriptions to FTSO price updates, State Connector attestations, and new block notifications.

## Technical Documentation

Quick start for developers

### Supported RPC Methods

Flare supports standard Ethereum JSON-RPC methods plus Flare-specific extensions for data protocols:

- **eth\_blockNumber** — current block number
- **eth\_getBalance** — FLR balance
- **eth\_call** — call contract functions
- **eth\_sendRawTransaction** — submit transactions
- **eth\_getTransactionReceipt** — transaction status
- **eth\_getLogs** — event logs including FTSO updates
- **eth\_gasPrice** — current gas price
- **eth\_estimateGas** — gas estimation
- **eth\_subscribe** — WebSocket subscriptions

### Code Examples

💻

#### JavaScript (ethers.js) — Access FTSO Price Feed:

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

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

// Verify network
const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId); // 14

// Access FTSO price feed for BTC/USD
const FTSO_REGISTRY = '0x1000000000000000000000000000000000000003';
const ftsoABI = [
  'function getCurrentPriceWithDecimals(string) view returns (uint256, uint256, uint256)'
];
const ftso = new ethers.Contract(FTSO_REGISTRY, ftsoABI, provider);

const [price, timestamp, decimals] = await ftso.getCurrentPriceWithDecimals('BTC');
console.log('BTC Price:', Number(price) / Math.pow(10, Number(decimals)));
console.log('Timestamp:', new Date(Number(timestamp) * 1000));
```

💻

#### Python (web3.py) — Flare FTSO Integration:

```
from web3 import Web3

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

print('Connected to Flare:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id)  # 14

# Access FTSO for ETH price
FTSO_REGISTRY = '0x1000000000000000000000000000000000000003'
ftso_abi = [{'constant':True,'inputs':[{'name':'_symbol','type':'string'}],'name':'getCurrentPriceWithDecimals','outputs':[{'name':'_price','type':'uint256'},{'name':'_timestamp','type':'uint256'},{'name':'_decimals','type':'uint256'}],'type':'function'}]

ftso = w3.eth.contract(address=FTSO_REGISTRY, abi=ftso_abi)
price, timestamp, decimals = ftso.functions.getCurrentPriceWithDecimals('ETH').call()
print(f'ETH Price: ${price / 10**decimals}')
```

💻

#### WebSocket — Monitor FTSO Price Updates:

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

// Monitor FTSO price reveal events
const FTSO_MANAGER = '0x1000000000000000000000000000000000000003';
const filter = {
  address: FTSO_MANAGER,
  topics: [ethers.id('PriceRevealed(string,uint256,uint256)')]
};

provider.on(filter, (log) => {
  console.log('New FTSO price revealed:', log);
});

// Monitor new blocks
provider.on('block', (blockNumber) => {
  console.log('New Flare block:', blockNumber);
});
```
