# Airdrop/Whitelist Complete

We continue with projects that have not yet launched their tokens. We covered [DEX Aggregators](https://medium.com/@CalendarDefi/airdrop-whitelist-complete-guide-the-dex-aggregator-series-a6b160cb1741) in a previous article. Today we focus on the cross-chain bridges.

Usually bridging once is sufficient for airdrop eligibility from experience of the $GB [airdrop](https://twitter.com/goodbridging/status/1436474396894449667?lang=en). No guarantee of airdrops from any of these projects as usual. You will need to pay ETH mainnet gas fees in some of these bridges. Consider yourself whether it will be worth the cost.

**Note: If your wallet doesn’t have the network you will bridge into or from, you can always add them at** [**chainlist.org**](https://chainlist.org/)**.**

**Hop Protocol**

[https://app.hop.exchange/](https://app.hop.exchange/)

A bridge that links ETH Mainnet, Polygon, Arbitrum, Optimism and xDai. No hints of token launch yet.
