About rpchub

rpchub is a free, community-driven tool for discovering and testing RPC endpoints across EVM-compatible blockchains. We aggregate RPC providers from public sources and provide real-time latency probing, block height verification, and privacy policy transparency to help developers and users choose the most reliable and trustworthy RPC provider for their needs.

What we do

  • Chain Explorer — Browse 500+ EVM-compatible networks with detailed metadata including chain IDs, native currencies, explorers, and faucets.
  • Multi-Chain Balance Checker — Query assets across all major EVM blockchains including native tokens (ETH, BTC, SOL, BNB, MATIC, AVAX) and popular ERC20 tokens (USDT, USDC, WBTC, WETH). Enter a wallet address to check all chain balances instantly with real-time USD valuation, concurrent querying, and dynamic refresh.
  • Real-Time Gas Tracker — Monitor gas prices across the top 24 EVM chains with auto-refresh every 15 seconds. Supports both EIP-1559 (base fee + priority fee) and legacy gas price formats. View Slow/Standard/Fast fee tiers with instant latency data. Chains are displayed in the same order as the Chain Explorer for consistency.
  • Real-time RPC Probing — Test RPC endpoints for availability, latency, and block height in real time.
  • Privacy Transparency — Understand how each RPC provider handles your data with clear privacy labels.
  • Wallet Integration — Add any supported network to MetaMask or other Web3 wallets with one click.
  • JSON-RPC Playground — Send raw JSON-RPC requests to any endpoint and inspect decoded results.
  • Tools Suite — A comprehensive set of EVM development tools including ABI Encode/Decode, Transaction Decoder, Event Topic calculator, 4Bytes signature lookup, Unit Converter, Hex Converter, and more. All tools work locally in your browser without requiring any external dependencies.
  • Cast Terminal — Execute Foundry cast commands directly through a web interface without installing any CLI tools. Supports 70+ commands including ENS resolution, signature lookup, encoding/decoding, and on-chain queries.
  • Faucet Directory — Find testnet token faucets for EVM-compatible chains, organized by network.
  • RPC Monitor — Monitor your RPC endpoints for uptime and latency. Get email alerts when endpoints go offline. Free plan includes 3 monitors and 1 email. VIP plan unlocks 100 monitors and 10 emails for just 5 USDT/month.
