    mnemonic: string,
    // network - type of network [TESTNET|MAINNET|DEVNET]
    // default is MAINNET even if no network is passed
    network: string (TESTNET | MAINNET | DEVNET)
});

const keyringState = await solanaController.addAccount();

Export the private key of an address present in the keyring

const privateKey = await solanaController.exportPrivateKey(address);

Get all accounts in the keyring

const privateKey = await solanaController.getAccounts();

Sign a transaction

const signedTx = await solanaController.signTransaction(solanaTx: TransactionObj);

solanaTx: {from, to, amount}

   txnType: MINT_NEW_TOKEN, // type constant
   from: // sender address
}

parameters:

name: transaction,
type: TransactionObj, // refer to the above 4 transactionObj types.

returns: {signedTransaction: Buffer} signed raw transaction

Sign a message

const signedMsg = await solanaController.signMessage(msgString, address);

Get fees

const fees = await solanaController.getFee(address);

Get balance

const balance = await getBalance(address, network); // if network !== TESTNET then it will fetch mainnet balance
