Ethereum Address Lookup and Labels

Inspect an Ethereum address for its account type, known presentation entity, and attributed labels through one normalized response.

EOA and contracts
Account-based
No API key

Live lookup

Enter a public Ethereum address

Address format

One address shape, different account roles

Ethereum addresses use 0x followed by 40 hexadecimal characters. The same visible shape can represent an externally owned account or a smart contract, so the response keeps address type separate from entity attribution.

EOA: An externally owned account controlled through a key
Contract: An address containing deployed smart-contract code
Entity: The normalized organization or service name when known
Label: A role or characteristic with source and status metadata

Response model

Name tags and API labels answer different questions

Explorer name tags are useful display annotations. CryptoLabel exposes normalized entity and label fields so software can inspect categories, source type, detection method, and status without parsing an explorer page.

Interpretation

What the result does and does not establish

01

An Ethereum address is not always a user wallet; it may be a contract or service-controlled account.
02

A contract creator, protocol entity, and contract role are separate pieces of information.
03

The lookup does not return token holdings, balances, transaction history, or a risk score.

Questions

Ethereum lookup, precisely defined

Is every Ethereum address a wallet?: No. The same address format is used for externally owned accounts and smart contracts.
Can a contract have an entity label?: Yes. A known protocol or service can be represented as the presentation entity while labels describe the contract role.
Are CryptoLabel labels the same as explorer tags?: Not exactly. CryptoLabel normalizes attribution into stable API fields and includes provenance and status information where available.
