Networks & metadata

ChainGate provides programmatic access to all supported networks and their metadata through the cg.networks collection. This is useful for dynamically building interfaces, validating inputs, or retrieving consistent information across multiple chains.

You can:

Iterate over all supported networks
Access detailed network metadata (name, symbol, decimals, address types, chain ID, etc.)
Detect network type (EVM vs UTXO) via instanceof
Create custom EVM networks via cg.networks.evmRpc() — turn any Ethereum RPC endpoint into a first-class network

Quick example

import { ChainGate } from 'chaingate'

const cg = new ChainGate()

// Iterate all networks
for (const network of cg.networks) {
  console.log(`${network.name} (${network.symbol}) — decimals: ${network.decimals}`)
}

// Direct access by name
const btc = cg.networks.bitcoin
console.log(btc.name)          // 'Bitcoin'
console.log(btc.symbol)        // 'BTC'
console.log(btc.decimals)      // 8
console.log(btc.isTestnet)     // false

Supported networks

ChainGate currently supports these networks (expanded regularly):

Bitcoin

Ethereum

Avalanche

Dogecoin

Litecoin

Bitcoin Cash

Bitcoin Testnet

ChainGate offers three levels of blockchain support, each providing different capabilities:

Native support

Natively supported networks have dedicated API endpoints provided by ChainGate. This means you get rich, ready-to-use data that goes far beyond what a standard JSON-RPC node can provide: paginated transaction history, token balances (ERC-20/ERC-721/ERC-1155), NFT metadata, detailed network status, fee estimation, and more.

These networks are available as named properties on cg.networks and return a full-featured UtxoExplorer or EvmExplorer when passed to cg.explore().

Network	Type	Symbol	Access
Bitcoin	UTXO	BTC	`cg.networks.bitcoin`
Litecoin	UTXO	LTC	`cg.networks.litecoin`
Dogecoin	UTXO	DOGE	`cg.networks.dogecoin`
Bitcoin Cash	UTXO	BCH	`cg.networks.bitcoincash`
Bitcoin Testnet	UTXO	tBTC	`cg.networks.bitcointestnet`
Ethereum	EVM	ETH	`cg.networks.ethereum`
Avalanche	EVM	AVAX	`cg.networks.avalanche`

RPC support

ChainGate provides JSON-RPC proxy endpoints for 12 networks (Ethereum, Polygon, Arbitrum, Base, Avalanche, BNB Smart Chain, Sonic, Bitcoin, Litecoin, Dogecoin, Bitcoin Cash, and Bitcoin Testnet), all authenticated with your API key. Point cg.networks.evmRpc() at any EVM chain's RPC URL to get wallets, transfers, balances, fee estimation, and broadcasting out of the box. The only difference versus native support is that transaction history, token balance aggregation, and NFT metadata endpoints are not available on these chains.

All natively supported networks are also available via RPC. The additional EVM networks reachable through cg.networks.evmRpc() are:

Network	Property	Chain ID
Sonic	`cg.rpcUrls.sonic`	146
Polygon	`cg.rpcUrls.polygon`	137
Arbitrum	`cg.rpcUrls.arbitrum`	42161
BNB Smart Chain	`cg.rpcUrls.bnb`	56
Base	`cg.rpcUrls.base`	8453

const polygon = cg.networks.evmRpc({
  rpcUrl: cg.rpcUrls.polygon,
  chainId: 137,
  name: 'Polygon',
  symbol: 'POL',
})
const connector = cg.connect(polygon, wallet)

Global endpoint support

The Global explorer (cg.exploreGlobal()) provides cross-network market data, real-time network information, and logo URLs for 34 networks. This includes all natively and RPC-supported networks, plus many additional EVM chains. Use it for dashboards, portfolio views, or any UI that needs prices and network metadata — including comparing chains by price or gas fees — without performing on-chain operations.

Network	Symbol	Network	Symbol
Bitcoin	BTC	Optimism	OP
Litecoin	LTC	Linea	LINEA
Dogecoin	DOGE	PulseChain	PLS
Bitcoin Cash	BCH	Blast	BLAST
Bitcoin Testnet	tBTC	Scroll	SCR
Ethereum	ETH	Gnosis Chain	GNO
Sonic	S	Unichain	UNI
Polygon	POL	opBNB	BNB
Arbitrum	ARB	Kava	KAVA
Avalanche	AVAX	Moonbeam	GLMR
BNB Chain	BNB	Taiko	TAIKO
Base	BASE	Chiliz	CHZ
Berachain	BERA	Evmos	EVMOS
Mantle	MNT	Moonriver	MOVR
Celo	CELO	Syscoin	SYS
Peaq	PEAQ	HAQQ	ISLM
Soneium	SON	Bahamut	FTN

Custom EVM networks via RPC

You can interact with any EVM network by providing a JSON-RPC endpoint — bring your own node, point at a third-party provider, or reuse ChainGate's built-in proxies:

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

// Or use ChainGate's built-in RPC proxy
const polygon = cg.networks.evmRpc({
  rpcUrl: cg.rpcUrls.polygon,
  chainId: 137,
  name: 'Polygon',
  symbol: 'POL',
})

const connector = cg.connect(polygon, wallet)

Key points

Uniform structure: Every network exposes consistent metadata for UI and logic.
Type-safe: cg.networks provides strong typing and autocompletion in TypeScript.
Named + iterable: Access networks by name (cg.networks.bitcoin) or iterate with for...of.
Custom EVM support: Use cg.networks.evmRpc() to connect to any EVM chain via JSON-RPC.
Display-ready: Use name, symbol, decimals, and nativeToken to render clean UIs.
