//ver1
//will return 8 wallets start from hdPath index at 0
const walletSigner = await cosmkit.getSignerFromMnemonic(8);

//ver2
//will return wallets which hdPath is 0,1,2
const walletSigner = await cosmkit.getSignerByPathIndex([0,1,2])

const accounts:AccountData[]=await cosmkit.getAccountData(walletSigner);
const address=accounts[0].address;
