EVM RPC explorer

EvmRpcExplorer is a typed wrapper around standard Ethereum JSON-RPC. It works with any EVM-compatible chain — you create the network via cg.networks.evmRpc({ rpcUrl, chainId, ... }) and ChainGate handles the rest.

The rpcUrl you pass can be either:

• One of ChainGate's hosted RPC proxies (cg.rpcUrls.ethereum, cg.rpcUrls.polygon, cg.rpcUrls.avalanche, etc.) — authenticated with your ChainGate API key, no extra signup needed. See ChainGate RPC endpoints for the full list.
• Any external JSON-RPC URL — Infura, Alchemy, QuickNode, a public endpoint, or a node you run yourself.

Both flavors give you the exact same EvmRpcExplorer API; the only difference is who hosts the underlying RPC node.

With ChainGate's hosted RPC

import { ChainGate } from 'chaingate'

const cg = new ChainGate()

const polygon = cg.networks.evmRpc({
  rpcUrl: cg.rpcUrls.polygon,   // ChainGate-hosted RPC, authenticated by your API key
  chainId: 137,
  name: 'Polygon',
  symbol: 'POL',
})

const explorer = cg.explore(polygon)

With an external RPC

const bsc = cg.networks.evmRpc({
  rpcUrl: 'https://bsc-dataseed.binance.org',  // any third-party or self-hosted RPC
  chainId: 56,
  name: 'BNB Smart Chain',
  symbol: 'BNB',
})

const explorer = cg.explore(bsc)

Available methods

Method	JSON-RPC call	Description
getBalance(address)	eth_getBalance	Native balance
getTransactionCount(address)	eth_getTransactionCount (latest)	Confirmed transaction count
getNonce(address)	eth_getTransactionCount (pending)	Next nonce to use
estimateGas(params)	eth_estimateGas	Gas estimate
getFeeData()	eth_gasPrice + EIP-1559	Fee data (gas price, max fee, priority fee)
sendRawTransaction(rawTx)	eth_sendRawTransaction	Broadcast a signed transaction
getTransactionReceipt(txHash)	eth_getTransactionReceipt	Transaction receipt

Example

const explorer = cg.explore(bsc)

// Check balance
const balance = await explorer.getBalance('0x...')

// Fetch current gas prices (works the same way on Polygon, BNB, Avalanche, etc.)
const feeData = await explorer.getFeeData()
console.log('Gas price:', feeData.gasPrice)

// Transaction receipt
const receipt = await explorer.getTransactionReceipt('0xtxhash...')
console.log('Status:', receipt.status)

How this fits with the rest of the EVM stack

ChainGate has three EVM-related things that are easy to mix up:

• EvmRpcExplorer (this page) — typed wrapper around standard JSON-RPC. The rpcUrl you pass can be one of ChainGate's hosted ones (cg.rpcUrls.*), or any external RPC (Infura, Alchemy, your own node). Limited to standard Ethereum RPC methods.
• cg.rpcUrls.* — JSON-RPC endpoints ChainGate hosts. Plug them into cg.networks.evmRpc() (which is what gets you here), or use them directly with ethers.js, viem, web3.js, or plain fetch. See ChainGate RPC endpoints.
• EvmExplorer — high-level explorer for natively supported chains (Ethereum and Avalanche). Talks to ChainGate's REST API and returns enriched data: token balances, transaction history, NFT metadata, congestion.

Pointing EvmRpcExplorer at cg.rpcUrls.ethereum or cg.rpcUrls.avalanche works fine, but for token aggregation, history, NFT metadata, or congestion on those chains you want EvmExplorer instead.
