Flare is a blockchain designed for data — providing decentralized access to high-integrity price feeds, cross-chain information, and Web2 APIs through native protocols. Built as an EVM-compatible Layer 1, Flare enables developers to build data-dependent applications without relying on centralized oracles or bridges.

Key capabilities:

  • Flare Time Series Oracle (FTSO) — decentralized price feeds
  • State Connector — trustless cross-chain data verification
  • LayerCake bridge — secure cross-chain asset transfers
  • Full EVM compatibility with Solidity support
  • Native integration with XRP Ledger, Dogecoin, and other chains
  • Built-in data acquisition protocols at the consensus layer
  • Fast finality with 1.8-second block time

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.

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);
});
