Scroll RPC Endpoint

Flat-rate Scroll RPC provider and Scroll RPC node access: free tier, no KYC, HTTP & WebSocket. Scroll mainnet chain ID 534352.

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)

• Which Chains Stopped? 43 Days of Block Timestamps Across 110 ChainsBetween August 25 and October 6, 2026, ten of 110 chains we scanned stopped producing blocks for 10 minutes or more. TAC was down 10.6 days, Neutron 77.75 hours, Cosmos Hub 24.8 hours, Cronos 17 hours. The full list, the method, and the raw data.
• Scroll RPC: Ethereum-Bytecode-Compatible zkEVMScroll is a bytecode-equivalent zkEVM rollup (chain ID 534352) — it targets opcode-level equality with Ethereum, so your existing contracts, audits, and tooling work with zero changes, while ZK validity proofs give ~1-hour hard finality instead of the 7-day optimistic window. Standard eth_* (viem/ethers/foundry). Here's the developer map, including how it differs from zkSync Era.
