The first Multi-signature Wallet on Aptos: Momentum Safe

Multi-signature is a special type of digital signature that allows two or more users to sign as a whole. In short, it decentralizes the control of asset ownership of a wallet address among multiple individuals.

Momentum Safe, as the first Multi-signature Wallet solution on the Aptos blockchain, has been successfully deployed to the Aptos mainnet. This article will explore the application scenarios of Momentum Safe and how it achieves secure and scalable Multi-signature Wallet functionality.

The Necessity of Momentum Safe

Momentum Safe adds an extra layer of protection for account assets and resources by introducing accounts that can be shared and operated by multiple users. This approach mitigates the single point of failure risk that may exist in a single-signature Wallet, making it particularly suitable for investment institutions, project teams, and decentralized autonomous organizations (DAOs).

Potential Application Scenarios

1. Project Foundation Financial Management Momentum Safe can effectively manage the foundation's tokens, including the Aptos native token APT and other tokens developed on the Aptos chain.

2. DAO Financial Management Through Momentum Safe, the DAO can allow selected members to control the Multi-signature Wallet and manage organizational funds through voting.

3. Project Revenue Management For example, managing royalties and minting fees after the launch of an NFT project.

4. Move Module Deployment Given the characteristics of the Aptos MOVE module, deploying multi-signature smart contracts can decentralize upgrade permissions and reduce the risk of abuse by developers.

5. Protocol Management Key functions for managing the protocol, such as parameter adjustments, emergency stops, and changes to community rewards.

The Security and Scalability of Momentum Safe

Momentum Safe adopts the native multi-signature transaction standard of Aptos and combines on-chain storage (MOVE module logic) to save the data required for multi-signature transactions.

Overview of the Transaction Process:

1. User signs the transaction
2. Submit the payload and signature to the Momentum Safe Move module
3. Basic transaction data is stored on-chain.
4. The last user to gather enough signatures submits the collective signature.
5. The blockchain verifies and completes Multi-ed25519 transactions.
6. MOVE VM executes the user-specified entry function

Features of Momentum Safe

In addition to the basic Multi-signature Wallet features, Momentum Safe will also support:

1. Comprehensive interoperability: Allows interaction with any Dapp.
2. Notification Service: Real-time notifications for account activities
3. DAPP Store: Recommend protocols and tools based on user needs.
4. Cross-chain integration: Introduce cross-chain assets to optimize the Aptos user experience.
5. Continuous Payment: Supports regular salary payments and subscription services
