While primarily designed for individual use, the concept of multi-signature (multisig) wallets is a powerful security and organizational feature for businesses and groups. A multisig wallet requires approvals from multiple private keys to execute a transaction. Tonkeeper for Android could implement support for such wallets, allowing a company treasury or a shared fund to be managed collectively. Setting up a multisig would involve defining the list of signers and the required number of approvals (e.g., 2 out of 3). When a transaction is proposed, all required signers would receive a notification and would need to approve it using their individual tonkeeper wallets. This distributes trust and eliminates single points of failure, as no one person can unilaterally move the funds. The implementation of such a feature would involve complex smart contract interactions, but the wallet’s UI would abstract this away, providing a simple approval interface for the user. This would elevate Tonkeeper from a personal finance tool to a sophisticated platform for decentralized organizational management on Android.
