Rubicans! Recently, we’ve held an amazing zkSync Era Galxe campaign together with Symbiosis and Mute.io! The overwhelming success of the campaign has motivated us to embark on another exciting adventure on the popular zkSync Era network, this time in collaboration with Galxe and SyncSwap DEX, the most popular DEX on zkSync Era!

zkSync Era Ecosystem

zkSync Era is the next big Ethereum Layer 2 project that everyone is buzzing about. Our team has conducted a thorough analysis of the zkSync Era ecosystem and its live projects, putting together a comprehensive guide on how to unlock the full potential of the new network, and covering the universal steps you need to follow to qualify for potential future airdrops.

How to Start on zkSync Era

Firstly, you need to add zkSync Era to your wallet: You can use any EVM-compatible wallet, such as MetaMask. The Argent Wallet is currently friendly to zkSync Era in test mode.

Here’s how to add it: https://era.zksync.io/docs/dev/fundamentals/interacting.html#connecting-to-zksync-era-on-metamask

Second, you’ll need Starter ETH — just like gas on Ethereum, you’ll need ETH to cover transaction fees on zkSync. You can easily transfer ETH from Ethereum, Avalanche, Optimism, BNB, or Arbitrum to zkSync using Rubic’s exchange at: https://app.rubic.exchange/?fromChain=BSC&toChain=ETH&from=ETH

Voila! You’re ready to make swaps into zkSync Era at app.rubic.exchange!

Swapping with Rubic, you’ll also receive bonus RBC tokens thanks to our Swap to Earn program, depending on the network you choose to swap from.
