How to perform the cheapest transactions (tx) on ZkSync?

Hello,
I'm continuing perform transactions on Zksync for the upcoming airdrop.
Here are some cheapest ways to perform transaction on the ZkSync:

1. Owlto Finance

Owlto Finance is a decentralized cross-rollup bridge focused on L2, providing cheaper and faster service. The team recently launched the daily "Check Iin" event on the ZkSync network.
You can also perform a transaction at a cost of only $0.12-0.20 by pressing the "Check In" button every day.

2. Nfts2me

NFTs2Me is a platform that simplifies the process of creating, deploying, and managing NFTs. NFTs2Me provides a user-friendly interface that allows users to create their own NFT artwork. It allows users to deploy their NFT contracts on the blockchain, making them immutable, verified, and accessible to the public.
Using the platform, you can mint NFT free collections deployed by users. The fee is between $0.40 and $0.70. You can see your NFTs on https://explorer.zksync.io/ by entering your wallet address.
Since each minted NFT is considered a separate contract interaction, you will interact with a different contract in each minting transaction.

You can perform these transactions every day or every week, depending on the transaction frequency you set.

Good luck!
