# Glittr SDK

The Glittr SDK is a client-side library written in Typescript designed to facilitates interaction with the Glittr protocol, allowing developers to integrate Glittr with their dApps. 

By utilizing this library, developers can create contracts, call contracs, and transfer Glittr assets on Bitcoin using the Glittr infrastructure.

### **Prerequisites:**

Installation with npm

```
npm install @glittr-sdk/sdk
```

Installation with yarn

```
yarn add @glittr-sdk/sdk
```

### Usage

#### Init SDK

Javascript

```javascript
const { GlittrSDK } = require("@glittr-sdk/sdk");

const NETWORK = "regtest";

const client = new GlittrSDK({
  network: NETWORK,
  electrumApi: "https://devnet-electrum.glittr.fi",
  glittrApi: "https://devnet-core-api.glittr.fi",
  apiKey: "<your-api-key>"
});
console.log(client)
```

Typescript/ES6

```typescript
import { GlittrSDK } from "@glittr-sdk/sdk";

const NETWORK = "regtest";

const client = new GlittrSDK({
  network: NETWORK,
  electrumApi: "https://devnet-electrum.glittr.fi",
  glittrApi: "https://devnet-core-api.glittr.fi",
  apiKey: "<your-api-key>"
});
console.log(client)
```

#### **Load Account**

Import Bitcoin account using private key hex:

<pre class="language-typescript"><code class="lang-typescript">import { Account } from "@glittr-sdk/sdk";
<strong>
</strong>const NETWORK = "regtest";

const account = new Account({
    privateKey: "your bitcoin private key",
    network: NETWORK
})

console.log(account.p2pkh())
console.log(account.p2wpkh())
</code></pre>

Or using WIF (Wallet Import Format) text

```typescript
import { Account } from "@glittr-sdk/sdk";

const NETWORK = "regtest";

const account = new Account({
    wif: "your WIF text",
    network: NETWORK
})

console.log(account.p2pkh())
console.log(account.p2wpkh())
```

#### Construct Glittr Transaction

```typescript
import { txBuilder } from "@glittr-sdk/sdk";

const c = txBuilder.freeMintContractInstantiate({
  simple_asset: {
    supply_cap: 2000n.toString(),
    divisibility: 18,
    live_time: 0,
  },
  amount_per_mint: 2n.toString(),
});

console.log(c)
```

### Example Create and Send Glittr Transaction

#### Freemint Contract Creation

```typescript
import { Account, GlittrSDK, txBuilder } from "@glittr-sdk/sdk";

async function main() {
  const NETWORK = "regtest";

  const client = new GlittrSDK({
    network: NETWORK,
    electrumApi: "https://devnet-electrum.glittr.fi",
    glittrApi: "https://devnet-core-api.glittr.fi",
    apiKey: "<your-api-key>"
  });
  const account = new Account({
    wif: "your WIF text",
    network: NETWORK,
  });

  const c = txBuilder.freeMintContractInstantiate({
    simple_asset: {
      supply_cap: 2000n.toString(),
      divisibility: 18,
      live_time: 0,
    },
    amount_per_mint: 2n.toString(),
  });

  const txid = await client.createAndBroadcastTx({
    account: account.p2pkh(),
    tx: c,
    outputs: []
  });
  
  console.log("TXID : ", txid);
}

main();
```
