RPCForge

The RPC Gateway Built for Web3 Developers

One endpoint. Five chains. Real-time dashboard. No per-request fees.




   



🚀 Featured on Product Hunt — RPCForge: Own Your RPC — our first ever launch!

What is RPCForge?

RPCForge is a hosted multi-chain RPC gateway that gives Web3 developers a single, reliable endpoint to interact with Ethereum, Polygon, BSC, Arbitrum, and Sepolia — without paying per-request fees to Infura or Alchemy.

Sign up → get an API key → start building. That's it.

curl -X POST https://rpcforge.onrender.com/eth \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

The Problem

Every Web3 developer hits this wall:

  • 💸 Infura & Alchemy charge per request — costs spiral as your dApp grows
  • 🔍 Zero visibility into your RPC traffic, errors, or latency
  • 🚫 Rate limits that kill your app during peak usage
  • 🔗 Multiple endpoints to manage across different chains
  • 🖥️ No CLI for scripting, CI/CD, or terminal workflows

The Solution

RPCForge gives you everything in one place:

✅ Flat monthly pricing — no per-call fees ever
✅ Real-time dashboard with live logs, charts, and latency tracking
✅ Per-tier rate limits up to 500 req/min
✅ One API key for all 5 chains
✅ Full-featured CLI on npm

Features

🌐 Multi-Chain Gateway

One API key works across all supported chains.

Chain Endpoint
Ethereum Mainnet POST /eth
Polygon POST /polygon
BSC POST /bsc
Arbitrum POST /arbitrum
Ethereum Sepolia POST /sepolia

📊 Real-Time Dashboard

  • Live traffic feed — WebSocket-powered request log with sub-second updates
  • Traffic chart — visualize request volume over time
  • Chain breakdown — see which chains you use most
  • Latency tracker — avg response times per chain
  • Request heatmap — 24-hour traffic visualization

🔑 API Key Management

  • Create multiple keys per account
  • Per-key analytics — requests, error rate, top methods, 7-day sparkline
  • Revoke keys instantly
  • Tier-based rate limiting per key

🛡️ Built-in Security

  • Method blacklist — blocks eth_sendRawTransaction, eth_sign, personal_sign by default
  • JWT-authenticated dashboard API
  • Per-key rate limiting with Redis
  • Supabase Row Level Security on all data

⚡ Performance

  • Multi-node failover — shuffles across nodes, retries on failure automatically
  • Response caching — TTL cache for eth_blockNumber, eth_chainId, eth_gasPrice
  • Upstash Redis — distributed cache with in-memory fallback

🧪 RPC Playground

Test any RPC method directly from your browser — no curl, no code.

💳 Stripe Billing

Full subscription management with Stripe Checkout and Customer Portal.

Quick Start

1. Sign up

Go to rpc-forge.vercel.app and create a free account.

2. Get your API key

Dashboard → API Keys → New Free Key.

3. Make your first request

curl -X POST https://rpcforge.onrender.com/eth \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

4. Integrate with your stack

ethers.js

import { ethers } from "ethers";

const provider = new ethers.JsonRpcProvider(
  "https://rpcforge.onrender.com/eth",
  undefined,
  { fetchOptions: { headers: { "x-api-key": "YOUR_API_KEY" } } }
);

viem

import { createPublicClient, http } from 'viem';
import { mainnet } from 'viem/chains';

const client = createPublicClient({
  chain: mainnet,
  transport: http("https://rpcforge.onrender.com/eth", {
    fetchOptions: { headers: { "x-api-key": "YOUR_API_KEY" } }
  })
});

wagmi

import { createConfig, http } from 'wagmi';
import { mainnet, polygon, arbitrum } from 'wagmi/chains';

export const config = createConfig({
  chains: [mainnet, polygon, arbitrum],
  transports: {
    [mainnet.id]: http("https://rpcforge.onrender.com/eth", {
      fetchOptions: { headers: { "x-api-key": "YOUR_KEY" }}
    }),
    [polygon.id]: http("https://rpcforge.onrender.com/polygon", {
      fetchOptions: { headers: { "x-api-key": "YOUR_KEY" }}
    }),
    [arbitrum.id]: http("https://rpcforge.onrender.com/arbitrum", {
      fetchOptions: { headers: { "x-api-key": "YOUR_KEY" }}
    }),
  },
});

Hardhat

module.exports = {
  networks: {
    mainnet: {
      url: "https://rpcforge.onrender.com/eth",
      headers: { "x-api-key": process.env.RPCFORGE_API_KEY },
      accounts: [process.env.PRIVATE_KEY]
    }
  }
};

CLI

The fastest way to manage RPCForge from your terminal.

npm install -g rpcforge-cli

When you run rpcforge you'll see:
