**Project Introduction**

Tusima is a cutting-edge multi-chain financial network rooted in zk-rollup technology using zero-knowledge proof tech and multi-chain interoperability. Tusima aims to establish itself as the cornerstone of privacy finance in the Web3 era.

**Funding Sources**

I did a quick search with GPT but couldn't dig up much about its backers. However, a brief LinkedIn sweep revealed that the Tusima team is quite active in various trade shows. Those interested might want to delve deeper:

**Step-by-Step Guide**

This guide, penned during some free time, is meant to be an easy, step-by-step walkthrough for those looking to benefit from the platform. Please excuse the lack of in-depth research. **The most challenging part is claiming the faucet**, but with this guide, **you'll breeze through it in under 5 minutes.**

**Part One: Faucet Claiming**

1. [https://goerli-faucet.pk910.de/](https://goerli-faucet.pk910.de/)

Here, you'll claim your Goerli faucet. Remember, no VPNs. Roughly 0.03 ETH should suffice.

2. [https://www.infura.io/faucet/sepolia](https://www.infura.io/faucet/sepolia)

Just a minute to sign up, then copy and paste your address to request Sepolia faucet.

3\. [https://bridgetest.tusima.network/faucet](https://bridgetest.tusima.network/faucet)

This is the official faucet - too good to pass up. You only need to claim Goerli, Sepolia, and zkSync (the latter can be claimed later).

**Part Two: Initiating Cross-Chain -** [https://bridgetest.tusima.network/transfer](https://bridgetest.tusima.network/transfer)

1.  First, transfer from Goerli > zkSync, about 0.01 ETH per transaction. Then, head back to claim zkSync's faucet. Just click on Claim zkSync Testnet to swiftly add zkSync testnet to your wallet. Wait around 3-5 minutes for the cross-chain funds to arrive, and you're set for the faucet.
    
2.  Next, from zkSync > Goerli, transfer a mere 0.001 ETH per transaction.
    
3.  Hit the Message button, send any text from zkSync > Goerli.
    
4.  Switch the mainnet by clicking the arrow, and send a message from Goerli > zkSync.
    
5.  Return to the cross-chain main page and initiate a 0.01 ETH transfer from Sepolia > Scroll.
    
6.  Hit Back, and repeat the Sepolia cross-chain transfer with another 0.01 ETH. (Ignore any pending notifications; just confirm.)
    
7.  Hit Back again, and repeat the Sepolia cross-chain transfer with another 0.01 ETH. (Ignore any pending notifications; just confirm.)
    

**Part Three: Completing Galxe Tasks**

It's super simple: retweet, join the Discord community, and browse some web pages. Click Claim once done.

Remember: After joining Discord, head to Rules > Get Verified. For the web browsing task, don't forget to actually visit the page.

Refresh to see all tasks done. Click Claim.

**Brief Conclusion**

In my view, cross-chain bridges typically offer modest rewards; worthwhile to set up a few accounts but not worth setting up hundreds of accounts. If you plan on using multiple accounts, I'd suggest isolating 2-3 wallets and transferring testnet coins between them; remember to claim the official faucet. This approach saves a ton of time, as you won't need to claim faucet on every single account.
