Gnosis RPC — Free Endpoint & Developer Guide

Gnosis Chain is an EVM sidechain secured by its own validators, using xDAI for gas. This guide shows how to connect to a free Gnosis RPC endpoint on MoltNode — no API key and no signup required.

What is Gnosis

Gnosis Chain is an EVM-compatible network secured by its own independent validator set rather than running as a rollup on top of Ethereum. It is known for low, stable transaction costs because gas is paid in a stablecoin-denominated native token, which keeps fee estimation predictable for everyday transactions, payments, and community applications.

Gnosis Chain is fully EVM-compatible, so it speaks the standard eth_* JSON-RPC method set, uses ordinary Ethereum-style addresses, and runs the same Solidity contracts and tooling you already know. Its native gas token is xDAI, and the network is identified by chain ID 100. Anything you have built for Ethereum or another EVM chain ports directly, with the main difference being the gas asset.

Gnosis RPC endpoint on MoltNode

MoltNode exposes Gnosis at one clean URL that is also a live RPC endpoint:

https://moltnode.ag/gnosis

There is no API key to provision and no account to create. The endpoint speaks JSON-RPC 2.0 over HTTP POST, and CORS is open so browser-based apps can call it directly. The URL is dual-purpose: a GET request opened in a browser returns a human-readable page about the chain, while a POST carrying a JSON-RPC body returns a machine response. The same address serves both people and programs.

To add it to a wallet, create a custom network with the RPC URL https://moltnode.ag/gnosis, chain ID 100, and currency symbol xDAI.

Probe it with curl

The fastest way to confirm the Gnosis JSON-RPC endpoint is responding is to request the latest block number:

curl -s https://moltnode.ag/gnosis \
  -X POST \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}'

You will get a JSON object with the current block height, hex-encoded, in the result field. Swap in any other standard method — eth_chainId, eth_getBalance, eth_call — to read whatever your app needs from the Gnosis node.

Use it from your app

Every JSON-RPC client works with the free Gnosis RPC. Here is a compact viem example pointed at the endpoint:

import { createPublicClient, http } from "viem";

const client = createPublicClient({
  transport: http("https://moltnode.ag/gnosis"),
});

const block = await client.getBlockNumber();
console.log("Gnosis block:", block);

The same URL drops into ethers, web3.py, wagmi, or any other library that accepts an HTTP RPC URL — no extra configuration beyond the endpoint.

Reliability & failover

The single moltnode.ag/gnosis URL is backed by upstream node infrastructure, and where more than one provider is configured, requests are tried in order. If the first upstream is unreachable or errors out, MoltNode automatically fails over to the next available provider. Upstream API keys are held server-side and never reach your client, so you get reliable Gnosis node access without managing any credentials.

There is no hard rate limit, but the endpoint is a shared, free Gnosis node available to everyone. Use it considerately: cache responses, avoid aggressive polling loops, and for high-volume production workloads, treat MoltNode as a fast default and failover layer rather than a single point of dependence.

For humans and agents

The dual GET/POST design serves developers and automated tools from one place. You can paste https://moltnode.ag/gnosis into a browser to read about the chain, while a wallet or script POSTs JSON-RPC to the same URL.

For programmatic discovery, MoltNode publishes a machine-readable catalog of every supported chain at https://moltnode.ag/api/chains and an agent-friendly overview at https://moltnode.ag/llms.txt. An AI agent can fetch the catalog, locate the Gnosis entry and its endpoint, and begin issuing eth_* calls without any manual setup.

Closing

The free Gnosis RPC endpoint at https://moltnode.ag/gnosis is a no-key, JSON-RPC Gnosis node ready for viem, ethers, wallets, and AI agents — with automatic failover built in. Point your client at the URL and start building.
