Flare RPC Endpoint

Fast, flat-rate Flare RPC node provider — free tier, no KYC, HTTP & WebSocket.

Flare is a Layer 1 EVM blockchain focused on providing decentralized data to smart contracts through native oracle protocols. It pairs EVM execution with built-in data acquisition layers (FTSO price feeds and the FDC state connector), so contracts can consume external price and chain data without third-party oracle deployments.

About Flare

Flare's genesis block was produced in 2022 and the FLR token distribution began in January 2023. The network is EVM-compatible and uses an Avalanche-derived Snowman++ consensus combined with a Federated Byzantine Agreement model, giving roughly 1.8-second blocks with near-immediate finality once a block is accepted.

Flare's distinguishing feature is its enshrined data protocols. The Flare Time Series Oracle (FTSO) supplies decentralized price and time-series feeds from independent data providers, and the Flare Data Connector (FDC) lets contracts verify state from other chains and Web2 sources. Developers build with standard Solidity tooling such as Hardhat, Foundry, ethers.js, and viem.

Common Use Cases on Flare

• Decentralized price feeds via FTSO
• Cross-chain state verification via FDC
• DeFi protocols and stablecoins
• Bridging external data into smart contracts
• Wrapped-asset and FAsset issuance

Flare Ecosystem

The ecosystem includes the native FTSO oracle network, the FAssets system for bringing assets like XRP and DOGE on-chain, and DeFi venues such as SparkDEX and BlazeSwap.

HTTP Endpoint

WebSocket Endpoint

Quick Start: Connect to Flare

cURL

curl -X POST https://rpc.swiftnodes.io/rpc/flare?key=YOUR_API_KEY \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

ethers.js

import { JsonRpcProvider } from "ethers";

const provider = new JsonRpcProvider(
  "https://rpc.swiftnodes.io/rpc/flare?key=YOUR_API_KEY"
);

const blockNumber = await provider.getBlockNumber();
console.log("Flare block:", blockNumber);

viem

import { createPublicClient, http } from "viem";

const client = createPublicClient({
  transport: http("https://rpc.swiftnodes.io/rpc/flare?key=YOUR_API_KEY"),
});

const blockNumber = await client.getBlockNumber();

web3.py

from web3 import Web3

w3 = Web3(Web3.HTTPProvider("https://rpc.swiftnodes.io/rpc/flare?key=YOUR_API_KEY"))
print("Flare block:", w3.eth.block_number)

Bridging to Flare

Assets move via the Stargate and LayerZero stack and other cross-chain bridges, while the FAssets protocol brings non-smart-contract assets such as XRP and BTC onto Flare.
