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.
| Chain | Native Token | Notes |
|---|---|---|
| Ethereum | ETH | Full coverage — tokens, NFTs, DeFi, DEX |
| Polygon | POL | Full coverage |
| BNB Smart Chain | BNB | Full coverage |
| Arbitrum | ETH | Full coverage |
| Base | ETH | Full coverage |
| Optimism | ETH | Full coverage |
| Avalanche | AVAX | Full coverage |
| Fantom | FTM | Full coverage |
| Linea | ETH | Full coverage |
| Cronos | CRO | Full coverage |
| Gnosis | xDAI | Full coverage |
| Moonbeam | GLMR | Full coverage |

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.
| Format | Detected as | Example |
|---|---|---|
| 0x + 40 hex chars | EVM address | 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 |
| base58 string (~44 chars) | Solana address | So11111111111111111111111111111111111111112 |
| .eth domain | ENS name — auto-resolved to EVM address | vitalik.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.
What chain is [TOKEN] on? — ONYX will look it up and confirm before running the analysis.Ready to explore DeFi opportunities across chains? See DeFi & News Queries for yield finder and portfolio analysis examples.
