# Wallet Configuration

## Connecting MetaMask

Z2 is EVM-compatible, so it connects to MetaMask as a custom network.

**Add Network → Add a network manually (Testnet):**

| Field              | Value                                 |
| ------------------ | ------------------------------------- |
| Network Name       | `Z2 Testnet`                          |
| Default RPC URL    | `https://z2-test-node.zetrix.com`     |
| Chain ID           | `938748`                              |
| Currency Symbol    | `ZETRIX2`                             |
| Block Explorer URL | `https://z2-test-explorer.zetrix.com` |

> \[!NOTE] For Mainnet, use the production sub-domains (`z2-node.zetrix.com`, `z2-explorer.zetrix.com`) and the Mainnet Chain ID once assigned. Always verify the Chain ID via `eth_chainId` before signing transactions.
>
> Chain ID `938748` and Currency Symbol `ZETRIX2` are the current Testnet wallet values (see [Gas Token & ZETRIX2 Symbol](/zetrix-l2-documentation/usage/tokenomics.md#gas-token--zetrix2-symbol)).

## Why "ZETRIX2" Is Used as the Native Symbol

The `ZETRIX2` symbol is the display symbol for the **L2 native gas unit**. It does **not** represent Ethereum's ETH or L1 native ZETRIX directly. The economically meaningful asset on Z2 is **Wrapped Zetrix (wZETRIX)**: L1 native ZETRIX is deposited and represented on L2 as the wZETRIX ERC-20 token. The L2 native (`ZETRIX2`-symbol) unit is used only to pay gas and currently carries no external value (see [Tokenomics](/zetrix-l2-documentation/usage/tokenomics.md#tokenomics)).

> \[!IMPORTANT] The `ZETRIX2` symbol is a **display convention** for the native gas unit on Z2. It has no relationship to Ethereum mainnet value or L1 native ZETRIX. The only valued token on Z2 today is **wZETRIX** — the ERC-20 representation of deposited native ZETRIX.

## Wrapped Zetrix (wZETRIX)

**Wrapped Zetrix (wZETRIX)** is the ERC-20-style representation of native ZETRIX on L2. Native ZETRIX deposited from L1 is represented on L2 as wZETRIX, making it usable in EVM smart contracts (which expect ERC-20 interfaces for programmable transfers).

```

* **Deposit:** L1 ZETRIX → wZETRIX on L2 (via Relayer/bridge).
* **Withdraw:** wZETRIX on L2 → L1 ZETRIX (via bridge + L1 finalization).
* **Utility:** wZETRIX is transferable and composable within L2 smart contracts. See [Asset Flow](/zetrix-l2-documentation/usage/asset-flow.md#asset-flow).
