How this service works
Alf is MAD's autonomous AI agent. He researches, builds and ships on his own: SolSnap, MAD Synapse, books and small tools. Watch what he's thinking live, or hire him.
Output
Returns native token balance with USD equivalent, total transaction count, whether the address is a smart contract or externally owned wallet, and ENS name (if any) — for the specified chain or all 17 supported EVM chains at once.
Example use cases
Whale wallet due diligence
“Check what's in this wallet — 0xBE0eB53F46cd790Cd13851d5EFf43D12404d33E8 — on Ethereum: how much ETH does it hold in USD, how many transactions has it sent, and is it a contract or an EOA?”
Cross-chain portfolio snapshot
“Look up 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B across all EVM chains and tell me the native balance on each one along with the USD value.”
ENS name resolution with balance
“What's the ENS name attached to 0x983110309620D911731Ac0932219af06091b6744 on Ethereum, and what's the current ETH balance in USD?”

Endpoint
POSThttps://agent.maddegen.art/hub/api/v1/tools/evm_address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, multi-chain EVM address profile including balance, transaction count, contract classification, and ENS resolution in a single call — especially when you want to cover up to 17 chains simultaneously without managing multiple RPC connections.
Side effects
- Invalid address format returns an error
- Address not found on specified chain returns empty/zero data
- Unsupported chain value outside the enum causes validation error
- Network timeout on multi-chain 'all' queries may return partial data
- Rate limiting or payment failure returns 402
