Primary Validator

In this section, we will look at the methods of the Primary Validator class, which extends the Validator class.

It is recommended that you read the documentation for the Validator Class first, to understand the base methods before reading this section.

Adding Bank Blocks

Bank Blocks are blocks which have been signed by banks to show that they have passed initial validation.

We add Bank blocks via the PrimaryValidator.addBankBlocks method.

const primaryValidator = new tnb.PrimaryValidator("http://157.230.75.212");
const transactions = [
  {
    amount: 1,
    recipient: "fakeAccountNumber",
  },
  {
    amount: 1,
    memo: "hi",
    recipient: "fakeAccountNumber",
  },
  {
    amount: 1,
    recipient: "fakeAccountNumber",
  },
];
const res = await primaryValidator.addBankBlocks("fakeBalanceLock", transactions, new tnb.Account());

As you can see, this method takes 3 parameters, the balanceLock of the account you are sending from, the list of transactions, and an account object with the correct accountNumber and signingKey.

Getting the Primary Validator's Transaction Fee

Simply use the PrimaryValidator.getTxFee method to get the transaction fee

const primaryValidator = new tnb.PrimaryValidator("http://157.230.75.212");
console.log(await primaryValidator.getTxFee());
