Evmos RPC Endpoint

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

Evmos is a proof-of-stake EVM Layer 1 built with the Cosmos SDK on the CometBFT consensus engine, designed to bring Ethereum-compatible smart contracts to the Cosmos ecosystem. SwiftNodes provides Evmos mainnet RPC over HTTP and WebSocket.

About Evmos

Evmos launched its mainnet in 2022 (the current evmos_9001-2 chain followed an early relaunch in April 2022). It runs CometBFT (Tendermint) BFT consensus with roughly 2-second block times and instant finality.

Evmos pairs a full Ethereum EVM with Cosmos IBC, letting Solidity contracts interoperate with the Cosmos ecosystem. The native EVMOS token (18 decimals, base denom atto EVMOS) is used for staking, governance, and gas. Evmos has since evolved into the evmOS stack for building EVM chains on Cosmos.

Common Use Cases on Evmos

• EVM smart contracts on Cosmos
• Cross-chain DeFi via IBC
• Staking and governance
• Token issuance
• Interchain application development

Evmos Ecosystem

Hosts EVM-native DeFi and NFT applications and connects to the broader Cosmos ecosystem; the underlying evmOS stack is used to build additional EVM-on-Cosmos chains.

ethers.js

import { JsonRpcProvider } from "ethers";

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

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

viem

import { createPublicClient, http } from "viem";

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

const blockNumber = await client.getBlockNumber();

web3.py

from web3 import Web3

w3 = Web3(Web3.HTTPProvider("https://rpc.swiftnodes.io/rpc/evmos?key=YOUR_API_KEY"))
