# Bridging

New ZkSync users who want to participate in OpenFi should make sure they have $ETH on ZkSync in order to be able to pay for transaction/gas fees.

Bridging to ZkSync is here: [https://bridge.zksync.io/](https://bridge.zksync.io/) & [https://portal.zksync.io/bridge](https://portal.zksync.io/bridge)

If you're bridging from a network other than the Ethereum network, we recommend the following services:

[https://stargate.finance/transfer](https://stargate.finance/transfer) - a multi-network bridge for stablecoins

&#x20;[https://www.bungee.exchange](https://www.bungee.exchange) - an aggregator that shows the best available bridging options. Use their Refuel service to deposit smaller amounts in case you run out of $ETH to pay transaction fees.

[https://portal.zksync.io/bridge](https://portal.zksync.io/bridge) - for a full list of ZkSync network bridging services.

[https://bridge.zksync.io/](https://bridge.zksync.io/) - same as above but newer version
