# 3.1 Acquiring & Connecting to GRX

Getting started on GRX Chain is simple. Choose a centralised on-ramp via GroveX or a decentralised route via bridging + GRXswap, then add the GRX network to your wallet.

### Ways to acquire GRX

#### 1) Direct purchase on GroveX (centralised)

* **Pair:** GRX/USDT — buy GRX directly on the GroveX exchange.
* **AUD deposits:** Start an AUD deposit **inside your logged-in GroveX account** to receive the BSB, account number, and your **unique reference**. Use that exact reference so your funds are credited correctly.
* **Why this route?** Fast onboarding, order-book liquidity, fiat ramp, and a familiar exchange UX.

#### 2) Bridge assets → buy on GRXswap (decentralised)

* **Official bridge (current):** Use **grovex.io** to bridge supported assets (e.g., USDT) to GRX Chain.
* **Swap on the DEX:** Once bridged, trade for GRX on **GRXswap** (grxswap.io).
* **Why this route?** Keep assets in your self-custody wallet; interact natively with DeFi, staking, and governance.

> **Safety:** Only use **grovex.io** for bridging (until other official bridges are announced). Always confirm token and contract addresses on **GRXscan** before transacting.

### Add GRX Chain to your wallet

GRX Chain is compatible with **MetaMask**, **OKX Wallet**, and hardware wallets (**Ledger**, **Trezor**) via those apps.

**Mainnet**

* **Network Name:** GRX Chain
* **RPC URL:** `https://rpc.grxchain.io`
* **Chain ID:** `1110` (`0x456`)
* **Symbol:** GRX
* **Block Explorer:** `https://grxscan.io`

*(For wallet-specific steps to add a custom network, see your wallet’s documentation.)*

#### One-click “Add Network” (optional, MetaMask)

```html
<button id="add-grx">Add GRX Mainnet</button>
<script>
  document.getElementById('add-grx').onclick = async () => {
    if (!window.ethereum) return alert('Install MetaMask or a compatible wallet.');
    try {
      await window.ethereum.request({
        method: 'wallet_addEthereumChain',
        params: [{
          chainId: '0x456',
          chainName: 'GRX Chain',
          nativeCurrency: { name: 'GRX', symbol: 'GRX', decimals: 18 },
          rpcUrls: ['https://rpc.grxchain.io'],
          blockExplorerUrls: ['https://grxscan.io']
        }]
      });
    } catch (e) { console.error(e); alert('Unable to add network.'); }
  };
</script>
```

### Holding your GRX

You can:

* **Hold on GroveX** for centralised trading convenience and fiat on/off-ramps, or
* **Self-custody in your wallet** to use DeFi on GRX Chain (staking, governance, dApps).

> **Tip:** GRX is the **native gas** for fees. For ERC-20 integrations and DEX trading, many apps use **WGRX** (the wrapped ERC-20 form) alongside pegged assets (e.g., USDT). Verify contract addresses on **GRXscan**.

### Testnet (for rehearsals)

**Get test GRX (no value):** `https://faucet.grxchain.io`

**Testnet network params**

```json
{
  "chainId": "0x9CB",
  "chainName": "GRX Chain Testnet",
  "nativeCurrency": { "name": "tGRX", "symbol": "tGRX", "decimals": 18 },
  "rpcUrls": ["https://testnet.grxchain.io"],
  "blockExplorerUrls": ["https://testnet.grxscan.io"]
}
```

### Official tokens (quick reference)

* **WGRX (ERC-20):** `0x45C7287F897B3A79Cd3f6e4F14B4CE568f023bD5` (18 decimals)
* **USDT (pegged):** 0x173462F5eb7CA0D1ab6aaea846fEFe85A28029E2
* **BTC (pegged):** `0x2F4632ABAd26A1FF9212a76597fb3c3d8539E275`
* **ETH (pegged):** `0x02D129c8A26839c814925eE0f1D320F63114E1FE`

Always verify on **GRXscan** before interacting.

### Swap walkthrough (GRXswap)

1. Add **GRX Chain** to your wallet and hold a small **GRX** balance for gas.
2. Visit **grxswap.io** and connect wallet.
3. Select **From:** USDT (pegged) → **To:** **WGRX** (or **GRX** if supported).
4. Review route, slippage, and fees → **Swap** → confirm in wallet.
5. View tx on **GRXscan** (link pops up after submit).

### Bridging notes (important)

* **Official bridge (current):** **grovex.io** only.
* Some assets may require **KYC** on GroveX depending on your region.
* After bridging, wait for UI confirmation and a few block confirmations before swapping.

### Gas & fee guidance

* Keep a small buffer of **GRX** for approvals + swaps.
* If a tx stalls: increase gas slightly or resend with a higher replacement fee.

### Minimum confirmations (suggested)

* **Wallet UX / personal transfers:** \~12 confirmations.
* **High-value exchange or treasury ops:** \~60 confirmations.

### Troubleshooting quick fixes

* **Deposit to GroveX not showing:** Ensure you used your **unique reference** in the AUD transfer.
* **Token not visible in wallet:** “Import token” by **contract address** (don’t rely on name search).
* **Approval/swap failing:** Check allowance, router address, and slippage; read revert on **GRXscan**.
* **“Network not added” errors:** Manually enter RPC + Chain ID (`1110` for Mainnet).

### Safety & phishing

* Only trust: `grxchain.io`, `grxscan.io`, `rpc.grxchain.io`, `grovex.io`, `grxswap.io`.
* No one from GRX/GroveX will ever ask for seed phrases or remote access.
* Double-check token and dApp addresses on **GRXscan**.
