| `contract_address`                      | It describes whether this address is a contract address. "1" means true; "0" means false.                                      | If only the address is sent to the API and not the chain id, the "contract\_address" will not be returned. This is because there are cases where the same address is a contract in one public chain but not in other public chains. Determining the contract address is achieved by calling a third-party blockchain browser interface. Since it takes time for the browser interface to return, the field may be empty on the first request. Solution: the second call around 5s can return whether the address is the value of the contract normally. |
