TypeScript

SDK

1

In your project folder, create a minimal package.jsonfile:

{
  "name": "radius-quickstart",
  "version": "1.0.0",
  "type": "module",
  "dependencies": {
    "@radiustechsystems/sdk": "^1.0.0"
  }
}

2

Install the Radius TypeScript SDK:

npm i @radiustechsystems/sdk

3

Create a TypeScript file called index.ts:

Be sure to replace the RADIUS_ENDPOINT and PRIVATE_KEY values with your own. See also: Radius Testnet and Create a Private Key.

import {
  Account,
  Address,
  AddressFromHex,
  Client,
  NewClient,
  NewAccount,
  Receipt,
  withPrivateKey,
} from '@radiustechsystems/sdk';

// Replace the following values with your own
const RADIUS_ENDPOINT = "https://rpc.testnet.radiustech.xyz/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
const PRIVATE_KEY = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

async function main() {
  const client: Client = await NewClient(RADIUS_ENDPOINT);
  const account: Account = await NewAccount(withPrivateKey(PRIVATE_KEY, client));
  const recipient: Address = AddressFromHex('0x...'); // Replace with recipient address
  const amount: bigint = BigInt(100);
  const receipt: Receipt = await account.send(client, recipient, amount);

  console.log('Transaction hash:', receipt.txHash.hex());
}

main().catch(console.error);

Create a minimal tsconfig.jsonfile:

{
  "compilerOptions": {
    "target": "ES2022",
    "module": "NodeNext",
    "moduleResolution": "NodeNext",
    "esModuleInterop": true,
    "skipLibCheck": true
  }
}

Compile and run the code using the following command:

tsc && node index.js
