# MEZO Bridge & Contract Addresses

> Bridge MEZO tokens between Mezo and other networks using Wormhole NTT

The MEZO bridge enables transfers between Mezo and multiple networks including Ethereum, Base, BSC, and Solana using Wormhole's Native Token Transfer (NTT) protocol. This bridge maintains token fungibility while providing secure cross-chain functionality.

## How it Works

The MEZO bridge uses Wormhole's Native Token Transfer protocol to facilitate cross-chain transfers:

* **From Mezo to other chains**: MEZO tokens are locked on Mezo and the equivalent tokens are minted on the destination chain (Ethereum, Base, BSC, or Solana)
* **From other chains to Mezo**: MEZO tokens are burned on the source chain and equivalent tokens are unlocked on Mezo

This mechanism ensures that the total supply across all chains remains constant while allowing users to move their tokens freely between networks.

## Bridge Options

There are two user interfaces available for bridging MEZO tokens:

### Mezo dApp

The [Mezo dApp](https://mezo.org) provides a native bridging experience for transferring MEZO tokens between Mezo and Ethereum networks only.

**To bridge from Mezo to Ethereum (Withdraw):**

<Steps>
  <Step title="Connect your wallet">
    Connect your wallet to the Mezo dApp
  </Step>

  <Step title="Click Withdraw">
    Click "Withdraw" to bridge tokens from Mezo
  </Step>

  <Step title="Select MEZO token">
    Select MEZO token and enter the amount to withdraw
  </Step>

  <Step title="Confirm the transaction">
    Confirm the transaction in your wallet
  </Step>

  <Step title="Wait for confirmation">
    Wait for confirmation on both chains
  </Step>
</Steps>

**To bridge from Ethereum to Mezo (Deposit):**

<Steps>
  <Step title="Connect your wallet">
    Connect your wallet to the Mezo dApp
  </Step>

  <Step title="Click Deposit">
    Click "Deposit" to bridge tokens to Mezo
  </Step>

  <Step title="Select MEZO token">
    Select MEZO token and enter the amount to deposit
  </Step>

  <Step title="Confirm the transaction">
    Confirm the transaction in your wallet
  </Step>

  <Step title="Wait for confirmation">
    Wait for confirmation on both chains
  </Step>
</Steps>

### Wormhole Portal Bridge UI

For bridging MEZO tokens to Base, BSC, Solana or Ethereum use the [Portal UI](https://portalbridge.com/):

<Steps>
  <Step title="Connect your wallet">
    Connect your wallet to the Portal interface
  </Step>

  <Step title="Select chains">
    Select source and destination chains (Mezo ↔ Ethereum, Base, BSC, or Solana)
  </Step>

  <Step title="Choose MEZO">
    Choose MEZO as the token to bridge
  </Step>

  <Step title="Enter the amount">
    Enter the amount you want to bridge
  </Step>

  <Step title="Review transaction details">
    Review transaction details including fees and estimated time
  </Step>

  <Step title="Confirm the transaction">
    Confirm the transaction in your wallet
  </Step>

  <Step title="Wait for confirmation">
    Wait for confirmation on both chains
  </Step>
</Steps>

Both interfaces provide user-friendly experiences that handle all the complex interactions with the underlying NTT contracts.
