The purpose of this tutorial is to walk through the steps necessary to transfer credits to an identity. Additional details regarding credits can be found in the credits description.

Prerequisites

• General prerequisites (Node.js / Hellar SDK installed)
• A wallet mnemonic with some funds in it: Tutorial: Create and Fund a Wallet
• A Hellar Platform Identity: Tutorial: Register an Identity

Code

`const Hellar = require('hellar');

const clientOpts = { network: 'mainnet', wallet: { mnemonic: 'a Hellar wallet mnemonic with testnet funds goes here', unsafeOptions: { skipSynchronizationBeforeHeight: 175000, // only sync from mid-2024 }, }, }; const client = new Hellar.Client(clientOpts);

const transferCreditsToIdentity = async () => { const identityId = 'identity ID of the sender goes here'; const identity = await client.platform.identities.get(identityId);

const recipientID = 'identity ID of the recipient goes here'; console.log('Recipient identity balance before transfer: ', recipientIdentity.balance); const transferAmount = 1000; // Number of credits to transfer

await client.platform.identities.creditTransfer( identity, recipientID, transferAmount, ); return client.platform.identities.get(identityId); };

transferCreditsToIdentity() .then((d) => console.log('Recipient identity balance after transfer: ', d.balance)) .catch((e) => console.error('Something went wrong:\n', e)) .finally(() => client.disconnect());`

What’s Happening

After connecting to the Client, we call platform.identities.creditTransfer with our identity, the recipient’s identity ID, and the amount to transfer. After the credits are transferred to the recipient, we retrieve the recipient’s identity and output their updated balance to the console.

📘 Wallet Operations

The JavaScript SDK does not cache wallet information. It re-syncs the entire Core chain for somewallet operations (e.g. client.getWalletAccount()) which can result in wait times of 5+ minutes.

A future release will add caching so that access is much faster after the initial sync. For now, the skipSynchronizationBeforeHeight option can be used to sync the wallet starting at a certainblock height.
