Metis RPC Endpoint

Flat-rate Metis RPC provider and Metis RPC node access: free tier, no KYC, HTTP & WebSocket. Metis mainnet chain ID 1088.

Metis (Andromeda) is an EVM-equivalent Ethereum Layer 2 optimistic rollup that uses METIS as its native gas token. It is notable for being among the first optimistic rollups to decentralize its sequencer.

About Metis

Metis Andromeda launched its mainnet in 2021, originally forked from Optimism's OVM, as an EVM-equivalent optimistic rollup settling to Ethereum. It uses METIS, rather than ETH, as the native gas token.

Metis has worked to decentralize its sequencer, moving from a single sequencer to a sequencer pool, and is among the first optimistic rollups to pursue sequencer decentralization to reduce single points of failure. The network targets low fees and fast block times and is EVM-compatible, so Solidity tooling such as Hardhat, Foundry, ethers.js, and viem applies directly. It is used for DeFi, gaming, and DAC-style applications.

Common Use Cases on Metis

• Low-fee EVM transactions
• DeFi protocols
• On-chain gaming
• DAC-style applications
• Smart contract deployment
• Bridged liquidity

Metis Ecosystem

The Metis ecosystem includes DeFi deployments such as Hummus and Netswap, along with infrastructure projects supporting its decentralized sequencer.

Quick Start: Connect to Metis

cURL

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

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

viem

import { createPublicClient, http } from "viem";

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

const blockNumber = await client.getBlockNumber();

web3.py

from web3 import Web3

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

Metis guides from the blog

• Metis RPC: An L2 With a Decentralized SequencerMetis is an EVM-equivalent optimistic rollup (chain ID 1088) notable for moving from a single sequencer to a sequencer pool — reducing the single-operator risk most L2s still carry. It's standard EVM (viem/ethers/foundry work), with METIS (not ETH) as gas. Here's the developer map, including what sequencer decentralization does and doesn't change for you.
