Scroll RPC Endpoint

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

Scroll is a bytecode-equivalent zkEVM rollup on Ethereum. It compiles Solidity contracts with identical opcode behavior to mainnet, generating zk-SNARK proofs for state transitions to inherit Ethereum's security with sub-Ethereum gas costs.

About Scroll

Scroll launched mainnet in October 2023 after years of zkEVM research. The team focused on full opcode equivalence with the EVM, meaning developers can deploy existing Ethereum contracts to Scroll with no changes — the same audits apply, the same tooling works.

Unlike optimistic rollups, Scroll's zk proofs achieve finality on Ethereum in roughly an hour rather than 7 days, eliminating the long withdrawal window. This is a key advantage for capital-efficient applications.

Common Use Cases on Scroll

• DeFi requiring fast L1 finality (no 7-day wait)
• Cross-rollup applications via shorter withdrawal time
• Onchain games with cheap state changes
• Privacy-adjacent applications leveraging zk infrastructure
• Capital-efficient market making

Scroll Ecosystem

Aave V3, Uniswap V3, Compound, Pendle, and a growing native DeFi scene. Scroll has been less aggressive on token incentives than competitors, but maintains steady TVL growth.

Quick Start: Connect to Scroll

cURL

curl -X POST https://rpc.swiftnodes.io/rpc/scroll?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/scroll?key=YOUR_API_KEY"
);

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

viem

import { createPublicClient, http } from "viem";

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

const blockNumber = await client.getBlockNumber();

web3.py

from web3 import Web3

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