Multivault

MultiVault is the easiest way to save money as a group. You can find it right on your phone, since it’s available on Telegram. Just go to the chat section, type “MultiVault,” click on it, and it will take you to the main chat. It will automatically create a wallet for you, and through the menu you can access different options such as New User, I Need Help, Open the App, or Check My Wallet Balance. Through this Telegram mini-app, we want to build a community where transparency is present in every aspect, and where you can feel secure when saving your money.

This project was divided into different parts, with each team member focusing on their strengths. The backend handled the creation of smart contracts using Solidity with Hardhat 2 and Node, and stored metadata for the community wallets using Filecoin — all built on the Coinbase Developer Platform. In addition, most of the functionality can be accessed through a Telegram bot for greater convenience. We used technology from the Coinbase Developer Platform and Filecoin.
