Wallet Type Lookup

Description

Retrieves metadata about a wallet address on a specific network. This includes whether the address is a smart contract, whether it is in counterfactual status, and its Loopring wallet contract version (if applicable).

Use this endpoint to determine:

• Whether a wallet is a contract or EOAs (externally owned account)

• Whether a wallet uses counterfactual deployment (common for Loopring Smart Wallets)

• Which version of the Loopring wallet contract is associated (if any)
