# 02. Bridge between chains

Using bridges is one of the ways to get zkSync potential airdrop. Bridges are smart contracts that allow you to transfer your assets from different blockchains to zkSync and vice versa. 

Here you can find how to bridge tokens with zkSync native bridge as well as most popular ones that can reward with an airdrop [**Orbiter**](https://www.orbiter.finance/)**,** [**Stargate**](https://stargate.finance/) and [**Jumper**](https://jumper.exchange/)**.**

#### Supply your zkSync wallet using official bridge

One of the most common criteria for allocating airdrop is the use of an official bridge. It allows You to transfer your funds between Ethereum Network and zkSync ERA. Go to [**txBridge**](https://portal.txsync.io/bridge/). The txbridge, unlike official bridges on other networks, allows you to send not only native currency, but remember that you need ETH on destination chain to pay gas fees and do next steps.

### :comet: [**Orbiter.Finance**](https://www.orbiter.finance/)

Orbiter's bridge is very popular among zkSync network users. While transacting on Orbiter for a potential airdrop, one can also mark their presence on other networks like Starknet, Base, Mantle, Linea, Scroll, and Zora, where airdrops may also occur. Since the bridge fee is fixed, it's feasible to transfer larger amounts, thereby contributing to the volume.<br>

Bridging Steps:

1. Choose your token.
2. Select the source chain.
3. Pick the destination chain.
4. Enter the transfer amount.
5. Click 'send' and confirm in your wallet.&#x20;

### [**Stargate.Finance**](https://stargate.finance/)

On this platform on the zkSync network, there is an option to transfer only two tokens: WAGMI and MAV to a limited number of networks. This is beneficial as, in addition to exposure to a zkSync airdrop, it also potentially exposes users to a LayerZero airdrop, on which Stargate.Finance is built.

Bridging Steps:

1. Click on "Trade" in the navigation menu.&#x20;
2. Select the source and target tokens for the swap.&#x20;
3. Input the amount for swapping.&#x20;
4. Check the swap details, including fees and rates.
5. Confirm by clicking the "Swap" button.

### :comet: [**Jumper.Exchange**](https://jumper.exchange/)

Jumper Exchange now supports zkSync Era through its partnership with LI.FI. Users can bridge and swap to and from zkSync and over 17 EVM. Using this cross-chain swap may be rewarded when obtaining an airdrop on the zkSync network, but it also exposes you to a potential airdrop from Jumper.Exchange itself.

Cross-chain Steps:

1. Select the source network and token.
2. Choose the destination network and the desired token.
3. Enter the token amount to swap.
4. Pick the transaction route, then click “Start Swap”.
5. Confirm in your wallet.
