let param = {
mnemonic: `gaze supreme human audit aisle entry galaxy shy lock time such auto`,
hdPath: `m/44'/9004'/0'/0/0`
}
let privateKey = await wallet.getDerivedPrivateKey(param);
Generate address
import {StarknetWallet} from "@okxweb3/coin-starknet";
let wallet = new StarknetWallet()
let param: NewAddressParams = {
privateKey: '603c85d20500520d4c653352ff6c524f358afeab7e41a511c73733e49c3075e',

import {StarknetWallet} from "@okxweb3/coin-starknet";
let wallet = new StarknetWallet()
let param1: ValidAddressParams = {
address: "0x06c3c93eeb1643740a80a338b9346c0c9a06177bfcc098a6d86e353532090ae4"
};
let valid = await wallet.validAddress(param1); // true
let param2: ValidAddressParams = {
address: "1895a6a77ae14e7987b9cb51329a5adfb17bd8e7c638f92d6892d76e51cebcf"
