Supported Chains

ONYX covers 25+ EVM networks and Solana — here's how to target a specific chain in your queries.

EVM Chains

All major EVM-compatible networks are supported. You can query token data, wallet balances, holder distribution, DEX activity, and DeFi positions on any of the chains below.

Solana

Solana is fully supported for wallet analysis, token data, and NFT queries. SPL token balances, native SOL holdings, and NFT collections are all accessible. Use a base58 address (the standard Solana address format) and ONYX will automatically route the query to the Solana data layer.

How to Specify a Chain

By default, ONYX infers the most relevant chain from context — usually Ethereum for EVM tokens. To target a specific network, simply name it in your prompt.

Specifying chain for a token query

Add the chain name after the token symbol or contract address:

Analyze PEPE on Base

What is the holder distribution of USDC on Arbitrum?

Show me trending tokens on BNB Smart Chain

Specifying chain for a wallet query

If you want balances or activity on a specific chain rather than across all chains:

Check this wallet on Polygon: 0xabc…

What DeFi positions does this wallet have on Optimism?

Address Detection

ONYX automatically identifies the address type from its format — you do not need to specify the network for basic lookups.

FormatDetected asExample
0x + 40 hex charsEVM address0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045
base58 string (~44 chars)Solana addressSo11111111111111111111111111111111111111112
.eth domainENS name — auto-resolved to EVM addressvitalik.eth

ENS names are resolved automatically before the query is executed. If a name does not resolve, ONYX will let you know rather than returning incorrect data.

Cross-Chain Queries

When you do not specify a chain, ONYX may query across multiple networks depending on the request type. Wallet analysis, for example, aggregates balances from all supported EVM chains and Solana in a single response. Token queries default to the chain where the token has the most liquidity unless you specify otherwise.

Not sure which chain a token is on? Just ask: What chain is [TOKEN] on? — ONYX will look it up and confirm before running the analysis.
