# TypeScript SDK
The Supra L1 TypeScript SDK provides a convenient way to interact with and perform operations on Supra. It offers a set of utility functions, classes, and types to simplify the integration process and enhance developer productivity.
## Install the TypeScript SDK
```sh
npm install supra-l1-sdk
```
## Import the Package
```typescript
import { HexString, SupraAccount, SupraClient, BCS } from "supra-l1-sdk";
```

## Example
{% stepper %}
{% step %}
### Initialize a new project
{% code overflow="wrap" %}
```
npm init && npm add -D typescript @types/node ts-node && npx tsc --init && mkdir src && > src/quickstart.ts
```
{% endcode %}
{% endstep %}
{% step %}
### Install the TypeScript SDK
```
npm install supra-l1-sdk
```
{% endstep %}
{% step %}
### Import dependencies
```typescript
import {
HexString,
SupraAccount,
SupraClient,
BCS,
TxnBuilderTypes,
} from "supra-l1-sdk";
```
{% endstep %}
{% step %}
### Initialize the SupraClient
```typescript
let supraClient = await SupraClient.init(
"https://rpc-testnet.supra.com/"
);
```
{% endstep %}
{% step %}
### Initialize a SupraAccount
```typescript
let senderAccount = new SupraAccount(
Uint8Array.from(
Buffer.from(
"2b9654793a999d1d487dabbd1b8f194156e15281fa1952af121cc97b27578d89",
"hex"
)
)
);
```
{% endstep %}
{% step %}
### Fund the account with the testnet faucet
```typescript
console.log(
"Funding Sender With Faucet: ",
// To Fund Account With Test Supra Tokens
await supraClient.fundAccountWithFaucet(senderAccount.address())
);
```
{% endstep %}
{% step %}
### Set the receiver address
```typescript
let receiverAddress = new HexString(
"0xb8922417130785087f9c7926e76542531b703693fdc74c9386b65cf4427f4e80"
);
```
{% endstep %}
{% step %}
### Transfer supra to the receiver address
```typescript
// To Transfer Supra Coin From Sender To Receiver
let txResData = await supraClient.transferSupraCoin(
senderAccount,
receiverAddress,
BigInt(100000000),
{
enableTransactionWaitAndSimulationArgs: {
enableWaitForTransaction: true,
enableTransactionSimulation: true,
},
}
);
console.log("Transfer SupraCoin TxRes: ", txResData);
```
{% endstep %}
{% step %}
### Full quickstart code
{% code title="quickstart.ts" overflow="wrap" lineNumbers="true" %}
```typescript
import {
HexString,
SupraAccount,
SupraClient
} from "supra-l1-sdk";
(async () => {
// To Create Instance Of Supra Client, But In This Method We Don't Need To Pass ChainId.
// ChainId Will Be Identified At Instance Creation Time By Making RPC Call.
let supraClient = await SupraClient.init(
"https://rpc-autonet.supra.com/"
);
//Init a SupraAccount from a private key.
let senderAccount = new SupraAccount(
Uint8Array.from(
Buffer.from(
"2b9654793a999d1d487dabbd1b8f194156e15281fa1952af121cc97b27578d89",
"hex"
)
)
);
//Fund the sender account with the testnet faucet
await supraClient.fundAccountWithFaucet(senderAccount.address())
//Set the receiver address
let receiverAddress = new HexString(
"0xb8922417130785087f9c7926e76542531b703693fdc74c9386b65cf4427f4e80"
);
// To Transfer Supra Coin From Sender To Receiver
let txResData = await supraClient.transferSupraCoin(
senderAccount,
receiverAddress,
BigInt(1000),
{
enableTransactionWaitAndSimulationArgs: {
enableWaitForTransaction: true,
enableTransactionSimulation: true,
},
}
);
//Output the transaction data
console.log("Transfer SupraCoin TxRes: ", txResData);
})();
```
{% endcode %}
{% endstep %}
