# Contracts and Token Addresses

_Detailed reference for Mezo’s smart contracts and their role in the ecosystem._

_Source: https://mezo.org/docs/users/resources/contracts-reference_

## Token Contracts

You can add these tokens to your wallet in the Mezo Explorer. Open the token address in the explorer and click the **Add token to MetaMask** button next to the MUSD token address.

Some of the token contracts are `TransparentUpgradableProxy` contracts. Add the proxy address to your browser wallet manually rather than the token address behind the proxy. For example, in MetaMask, follow the instructions to [Import a Token](https://support.metamask.io/manage-crypto/portfolio/how-to-import-a-token-in-metamask-portfolio/). These tokens are not visible on your EOA in the [Mezo Explorer](https://explorer.mezo.org/) until you complete your first transfer and approval on the given token.

### MUSD token and bridge

The MUSD bridge is powered by Wormhole's Native Token Transfer (NTT) protocol, which enables secure cross-chain transfers while maintaining token fungibility. NTT allows tokens to be locked on the source chain and minted on the destination chain, or burned and unlocked when bridging back. Use the [Portal UI](https://portalbridge.com/) to bridge tokens.

For more information about NTT, see the [official Wormhole documentation](https://wormhole.com/docs/products/native-token-transfers/overview/).
