I transfered some eth to the zksync wallet, mint a NFT and made some transactions in the ZigZag. But the next steps I cannot work on: in the portal.zksync.io there is no Faucet option. Its not there anymore or am I doing something wrong?
They don't announce any airdrop plan.
What you are doing is proactively airdrop on-chain transactions which you believe that will be counted for their airdrop in future when Zksync team make snapshots on the blockchain and finalize list of eligible users for airdrop.
Bounty hunters look at great and generous airdrops of Uniswap, Optimism, Arbitrum and huge fund raised by Zksync and believe that Zksync team will do big airdrop for real users too. What you're doing is trying to be real users on their platform and chain.
