Please, take a look into two Catalyst projects that may be interesting to you. Both projects have detailed explanations and use cases in their descriptions. However, spending 2-5 minutes on short videos is more convenient for understanding ideas that we’re trying to translate into working Cardano tools.
[AdaPlus.io](https://AdaPlus.io) aims to save on transaction fees while combining many transactions with mass payouts into as little as possible. It also allows SPOs for marketing campaigns to pay delegators in case of zero blocks epochs or low rewards epochs. As an SPO myself, I already use it to pay my delegators. While working on this project and communicating with wallets developers, we also see a demand in wallets ratings. It can be helpful to avoid or at least be warned about sending money to scam addresses.
[CardanoWall.com](https://CardanoWall.com) is the next level of Proof of Existence. It may look like a tool for sending different types of messages to the Cardano blockchain, but it’s much more than that. CardanoWall uses cryptography to sign PoE messages, encrypt data, and store backups on the public internet while having all PoE hashes stored on an immutable blockchain. It also allows you to save and prove information on any public website by creating PoE of WARC files. Right now, I am working on the possibility to create and get your own NFTs from any PoE you create.
Thank you, and please support those projects if you like them by giving the thumbs up in the Catalyst Voting app.
