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, Hash Calculator, Smart Contract Explorer, Base58 Encoder, Address Validator, Timestamp Converter, Gas Estimator, Private Key Generator, and Private Key to Address converter. 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.
