Supported Chains

Overview

The Nansen API supports 37 blockchain networks across EVM and non-EVM ecosystems. Chain support varies by endpoint.

EVM Chains

EVM-compatible chains use the standard Ethereum address format (0x + 40 hex characters).

Chain	Value	Description
Ethereum	ethereum	Main Ethereum network
Arbitrum	arbitrum	Arbitrum One L2
Avalanche	avalanche	Avalanche C-Chain
Base	base	Coinbase L2
Bitlayer	bitlayer	Bitcoin L2
BNB Chain	bnb	BNB Smart Chain
Celo	celo	Celo network
Chiliz	chiliz	Chiliz Chain
Gravity	gravity	Gravity network
HyperEVM	hyperevm	Hyperliquid EVM
IOTA EVM	iotaevm	IOTA EVM
Linea	linea	Linea L2
Mantle	mantle	Mantle L2
Monad	monad	Monad network
Optimism	optimism	Optimism L2
Plasma	plasma	Plasma network
Polygon	polygon	Polygon PoS
Ronin	ronin	Ronin sidechain
Scroll	scroll	Scroll L2
Sei	sei	Sei EVM
Sonic	sonic	Sonic network
Unichain	unichain	Uniswap L2
Viction	viction	Viction (TomoChain)
zkSync	zksync	zkSync Era

Non-EVM Chains

Non-EVM chains have unique address formats. See Address Formats for details.

Chain	Value	Description
Algorand	algorand	Algorand network
Aptos	aptos	Aptos network
Bitcoin	bitcoin	Bitcoin network
Hyperliquid	hyperliquid	Hyperliquid DEX (perpetuals only)
NEAR	near	NEAR Protocol
Solana	solana	Solana network
Stacks	stacks	Stacks (Bitcoin L2)
Starknet	starknet	Starknet L2
Stellar	stellar	Stellar network
SUI	sui	SUI network
TON	ton	The Open Network
Tron	tron	Tron network

Using the "all" Chain

Some endpoints support "all" to query across all supported chains:

{
  "chains": ["all"]
}

This expands to all chains supported by that specific endpoint.

Chain Support by Endpoint

Not all chains are available on all endpoints. Here's the support matrix:

Smart Money Endpoints

Chain	Netflow	DEX Trades	Holdings	Historical
ethereum	Yes	Yes	Yes	Yes
solana	Yes	Yes	Yes	Yes
base	Yes	Yes	Yes	Yes
bnb	Yes	Yes	Yes	Yes
arbitrum	Yes	Yes	Yes	No
polygon	Yes	Yes	Yes	No
avalanche	Yes	Yes	Yes	No
optimism	Yes	Yes	Yes	No

Token God Mode Endpoints

Chain	Flows	Transfers	Holders	PnL
ethereum	Yes	Yes	Yes	Yes
solana	Yes	Yes	Yes	Yes
base	Yes	Yes	Yes	Yes
bnb	Yes	Yes	Yes	Yes
arbitrum	Yes	Yes	Yes	Yes
ton	Yes	Yes	Yes	No
tron	Yes	Yes	Yes	No

Profiler Endpoints

Chain	Balance	Transactions	PnL	Related
ethereum	Yes	Yes	Yes	Yes
solana	Yes	Yes	Yes	Yes
bitcoin	Yes	Yes	No	No
ton	Yes	Yes	No	Yes
tron	Yes	Yes	No	Yes

Examples

Single Chain Query

{
  "chains": ["ethereum"]
}

Multi-Chain Query

{
  "chains": ["ethereum", "solana", "base"]
}

All Chains Query

{
  "chains": ["all"]
}

Chain-Specific Considerations

Solana

• Uses base58 addresses

• Transaction lookup not supported

• Full support for Smart Money and TGM

Bitcoin

• Limited endpoint support (Profiler only)

• Supports P2PKH, P2SH, and Bech32 addresses

• No Smart Money or TGM support

TON

• Uses EQ.../UQ... address format

• Addresses are automatically normalized

• No PnL endpoints

Hyperliquid

• Perpetuals platform only

• Used for perp-specific endpoints

• No standard token endpoints
