Edge RPC — Free Endpoint & Developer Guide

Jun 20, 2026·3 min read

Edge is an EVM-compatible network. This guide shows how to connect to a free Edge RPC endpoint on MoltNode — no API key and no signup required.

What is Edge

Edge is an EVM-compatible blockchain network. Because it follows the EVM standard, it works with the same contracts, addresses, and tooling that developers already use across the Ethereum ecosystem, so you can deploy Solidity, sign transactions, and read chain state in exactly the familiar way.

Whatever the specifics of the network, the practical interface for developers is consistent: Edge exposes the standard eth_* JSON-RPC method set and accepts ordinary Ethereum-style accounts and signatures. Its native gas token uses the symbol ETH, and the network is identified by chain ID 3343. If you are evaluating Edge, the simplest starting point is to point a JSON-RPC client at a live endpoint and read from the chain directly.

Edge RPC endpoint on MoltNode

MoltNode gives Edge one clean URL that is also a working RPC endpoint:

https://moltnode.ag/edge

No API key is required and there is no signup. The endpoint speaks JSON-RPC 2.0 over HTTP POST, and CORS is open so browser apps can call it directly without a proxy. The URL behaves two ways: a GET opened in a browser shows a human-readable page about the chain, while a POST with a JSON-RPC body returns a machine response. One address, two audiences.

To use the free Edge RPC in a wallet, add a custom network with the RPC URL https://moltnode.ag/edge, chain ID 3343, and currency symbol ETH.

Probe it with curl

To verify the Edge JSON-RPC endpoint is live, ask for the latest block number:

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

The response is a JSON object with the current block height, hex-encoded, in result. Replace the method with any standard eth_* call — eth_chainId, eth_getBalance, eth_getTransactionReceipt — to read whatever your application needs from the Edge node.

Use it from your app

Any JSON-RPC client connects to the Edge RPC endpoint. Here is a minimal viem example pointed at the URL:

import { createPublicClient, http } from "viem";

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

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

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

Reliability & failover

Behind the single moltnode.ag/edge URL is MoltNode's upstream routing layer, designed for automatic failover. If an upstream provider is unavailable or returns an error, requests are routed to the next available source so your application keeps working. The upstream API keys stay server-side and are never exposed to your client, so you get reliable Edge node access without handling any credentials yourself.

There is no hard rate limit, but this is a shared, free resource. Please use it responsibly: cache results where practical, avoid tight polling loops, and for heavy production traffic, treat MoltNode as a fast default and a failover layer rather than your only dependency.

For humans and agents

The dual GET/POST behavior makes the endpoint useful to developers and automated tools alike. You can open https://moltnode.ag/edge in a browser to read about the chain, while a script or wallet POSTs JSON-RPC to the same URL.

For automated discovery, MoltNode publishes a machine-readable catalog of every supported chain at https://moltnode.ag/api/chains and an agent-oriented summary at https://moltnode.ag/llms.txt. An AI agent can fetch the catalog, find the Edge entry and its endpoint, and begin making eth_* calls without any human in the loop.

Closing

The free Edge RPC endpoint at https://moltnode.ag/edge gives you a no-key, JSON-RPC Edge node that works with viem, ethers, wallets, and AI agents — with automatic failover handled for you. Point your client at the URL and start building.
