# Bridging to Base

### Bridging to Base

To use PredictBase, your wallet must have:

* **USDC** (used to place bets)
* **ETH** (used to pay for gas/transactions)

Both assets must be on the **Base network**, not Ethereum Mainnet or any other chain.

***

#### What is Bridging?

**Bridging** is the process of moving assets (like USDC or ETH) from one blockchain (e.g., Ethereum) to another (e.g., Base).

This is necessary because tokens are chain-specific — you can’t use Ethereum-based USDC directly on Base.

#### Recommended Bridge: Base Official Bridge

The easiest and most reliable way to bridge is through the official Base Bridge:

🔗 <https://bridge.base.org>

#### What to Bridge

| Asset    | Purpose                      | Amount Recommended |
| -------- | ---------------------------- | ------------------ |
| **USDC** | Betting on PredictBase       | At least $5–$10    |
| **ETH**  | Gas for transactions on Base | 0.005 – 0.02 ETH   |

***

#### Step-by-Step: Bridging Funds

1. **Go to** <https://bridge.base.org>
2. Connect your wallet (MetaMask, Coinbase, etc.)
3. Select Ethereum (or the chain you’re sending from) as the source
4. Choose **Base** as the destination
5. Select the asset: USDC or ETH
6. Enter the amount and click **Bridge**
7. Approve the transaction in your wallet

⏱️ Bridging may take a few minutes depending on network congestion.

***

#### Pro Tips

* You can bridge both ETH and USDC in one session.
* Gas fees are cheaper than many Layer 2 networks.
* Some centralized exchanges (like Coinbase) now support direct withdrawal to Base — no bridge needed.

***

#### Important Notes

* Don’t try to send assets directly to Base using `Send` in MetaMask — always use a bridge.
* Always verify you’re on the correct URL: `https://bridge.base.org`
* PredictBase currently only supports [**Base USDC**](https://basescan.org/token/0x833589fcd6edb6e08f4c7c32d4f71b54bda02913) (token address: `0x833589fCD6EDB6e08f4c7c32d4f71B54BDA02913`)
