Mini Safe

Live demo: https://t.me/MiniSafeBot

Mini Safe is the Revolut Team Business of Web3, where you and your team members can interact with a team multisig wallet directly on Telegram, with a monthly spendable amount (starting at $1,000 for no approval required). We are using Telegram to improve user experience and create mass adoption for multisig wallets, then we want to be secured using a spendable amount.

Features

1️⃣ Interact with a Telegram bot and a mini Telegram app

2️⃣ Onboarding new members with Safe module

3️⃣ Start spending on different apps or send money to another Telegram ID / ENS

4️⃣ Cross-chain payments using CCTP (Cross-Chain Transfer Protocol)

5️⃣ Verification system using Dynamic

6️⃣ Granular Security

We are fixing a limit of $1,000 spendable by month using Telegram (customizable), it’s enough to be able to use P2P payments in Web3. Otherwise, if you want to use Telegram to spend more, we are setting up a granular security to do it. For example:

• ≤$1,000 = easy, use telegram
• $1,000-$5,000 = a Telegram friend needs to confirm (2FA)
• ≥$5,000 = sign with a hardware wallet

7️⃣ Telegram Notification System

When one of the signers is using the multisig wallet, other members are alerted with a notification, like for Revolut Business.

8️⃣ Multisig Invitations by Telegram Roles

If you install the bot in a Telegram group, roles on the multisig reflect the roles on the Telegram group. To add people to the multisig, you can simply invite them to the Telegram group.

• Member → simple view on multisig
• Manager → able to interact with funds
• Owner → able to interact with funds + invite a manager + revoke access

9️⃣ Gasless onboarding

We are sponsoring transaction fees using a paymaster to onboard people easily via Telegram.

🔟 Social Recovery

Take advantage of the powerful social trust on Telegram to define 3 guardians (trustworthy contacts) who will be able to help you in case you lose access to your multisig wallet.
