I found one of the future criteria for the $ZKS airdrop.

I'm sure you're not eligible for this #airdrop multiplier. Check out How to get it

I'm talking about Multi-sig @safe by @gnosischain .

The Safe Smart Wallet now officially supports zkSync Era Network.

It was already one of the criteria for receiving another Tier-1 airdrop and could be one for zkSync.

To create your own Gnosis Safe: • Head to https://app.safe.global/welcome • Connect your EVM wallet. • Switch to network to zkSync Era.

Add multiply owners to the smart safe: • Add a name of your account & Click "Next". • Select "Add new owner". • Choose any of your wallets. • Click "Next" & Confirm the transaction. • Set at least "2" in the threshold tab.

Send Funds to your wallet to make transactions: • Get your zkSync Era wallet address in your profile. • Transfer some $ETH to this address. Now we can use transaction builder.

To send a transaction with multi-sig wallet : • Click on "New transaction". • Select "Send tokens". • Enter all the needed info just in your Metamask. • Confirm the transaction from as many wallets as you specified as a minimum number when you've created this safe.

The safe wallet was one of the multi-sig wallets, which could give you an extra criterion of @optimismFND first airdrop.

You just needed to make at least 10+ transactions with the Safe Wallet.

That fact can assert present/further partnerships with Safe as a criterion for drops.

How many people do you know who use multisig wallets? A few out of a hundred? This is one of the best opportunities to show that your wallet isn't Sybil. zkSync has supported Gnosis for a long time and can expand collaborations to a $ZKS reward for the most active enthusiasts.
