Claim SBC and Transact [Sign up, claim SBC, and send your first transaction on Radius Network]

View as Markdown

What you'll do

  1. Sign up at https://network.radiustech.xyz (no existing wallet necessary)
  2. Claim free SBC
  3. Send a test transaction
  4. View the transaction on the explorer

Prerequisites

  • An email address or social account
  • 2 minutes

Step 1: Sign up and get a wallet

Visit https://network.radiustech.xyz and sign up.

Radius uses Privy to create an embedded wallet for you automatically. No browser extension needed.

After signup, you'll have:

  • A Radius wallet address
  • Access to the dashboard
  • Access to claim SBC

Step 2: Claim SBC

In the dashboard, click Add Funds and claim SBC.

This is a real dollar pegged stablecoin (ERC-20 token) pegged 1:1 to USD. Use it for transactions on Radius and bridge it to other networks (Ethereum, Base).

:::tip Programmatic access To fund a wallet without the Dashboard — for example, in a script or agent workflow — use the Faucet API. The API is available on testnet only; there is no agentic faucet on mainnet. :::

Step 3: Send a transaction

Dashboard Instructions

  1. Click Send funds
  2. Enter the recipient address and amount of SBC ("stablecoin") you want to send
  3. Click Send

Programmatic Instructions

Alternatively, use viem (TypeScript):

import { createWalletClient, defineChain, http, parseUnits } from 'viem';
import { privateKeyToAccount } from 'viem/accounts';
 
// Define Radius Network (mainnet)
const radius = defineChain({
  id: MAINNET_CHAIN_ID,
  name: MAINNET_NAME,
  nativeCurrency: { name: NATIVE_TOKEN, symbol: NATIVE_TOKEN, decimals: 18 },
  rpcUrls: {
    default: { http: [MAINNET_RPC_URL] },
  },
});
 
// Your Privy wallet's private key (export from dashboard)
const account = privateKeyToAccount('{{PRIVATE_KEY}}');
 
const client = createWalletClient({
  account,
  chain: radius,
  transport: http(),
});
 
// Send {STABLECOIN} (ERC-20 transfer)
const hash = await client.writeContract({
  address: FEE_CONTRACT, // {STABLECOIN} contract
  abi: [
    {
      name: 'transfer',
      type: 'function',
      inputs: [
        { name: 'to', type: 'address' },
        { name: 'amount', type: 'uint256' },
      ],
      outputs: [{ name: '', type: 'bool' }],
      stateMutability: 'nonpayable',
    },
  ],
  functionName: 'transfer',
  args: ['0xRecipientAddress', parseUnits('1', STABLECOIN_DECIMALS)], // 1 {STABLECOIN} ({STABLECOIN_DECIMALS} decimals)
});
 
console.log('Transaction hash:', hash);
