Sending transactions

These are the main methods to send transactions to the blockchain.

The examples all assume an instance of the AergoClient named aergo.

import { AergoClient } from '@herajs/client';
let aergo = new AergoClient();

Using a server-side account

The easiest way to send transactions is when you are connected to a local node that stores the account you want to use. First unlock an account, then send a transaction using that account.

const address = 'AmNrsAqkXhQfE6sGxTutQkf9ekaYowaJFLekEm8qvDr1RB1AnsiM';
aergo.accounts.unlock(address, 'testpass').then(unlockedAddress => {
    const testtx = {
        from: unlockedAddress,
        to: unlockedAddress,
        amount: 123
    aergo.accounts.sendTransaction(testtx).then(txhash => {

// 9YBYY1onL9RLeEFxV9AdnCReV8i1k689KKsosS3eAx3X

Using a client-side account

If you created a public-private key pair on the client side, you can sign and send transactions directly. Remember you need the optional package @herajs/crypto for this.

import { createIdentity, signTransaction, hashTransaction } from '@herajs/crypto';
const identity = createIdentity();
const tx = {
    nonce: 1,
    from: identity.address,
    to: identity.address,
    amount: 100
tx.sign = await signTransaction(tx, identity.keyPair);
tx.hash = await hashTransaction(tx, 'bytes');

Getting transaction status

After submitting a transaction, if it is valid it will be picked up from a mempool and included in a block.

To retrieve the status of a transaction, refer to Reading from blockchain#Get transaction. At the moment, you need to poll getTransaction until it returns the block that includes the transaction.
