Introduction and User Guide to Momentum Safe, the First Multi-signature Wallet on the Aptos Blockchain

Multi-signature is a special type of digital signature that allows two or more users to collectively perform a signing operation. In short, it allocates the control of the assets at the wallet address to two or more people.

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

The Necessity of Momentum Safe

By introducing accounts that can be shared and operated by multiple parties, Momentum Safe provides an additional layer of protection for account assets and resources, effectively mitigating the single point of failure risk that may occur in a single-signature Wallet. This solution is particularly suitable for organizations such as investment institutions, project teams, and decentralized autonomous organizations (DAO).

Potential Application Scenarios

1. Project Foundation Financial Management Momentum Safe can assist project teams in managing foundation tokens, including the Aptos native token APT and other tokens developed on the Aptos chain.

2. DAO Financial Management Through Momentum Safe, DAOs can control Multi-signature Wallets by designated members and manage organizational funds through voting.

3. Project Revenue Management Suitable for managing royalties and minting fees after the release of NFT projects.

4. Move Module Deployment Considering the specificity of the Aptos MOVE module, using a Multi-signature Wallet to deploy smart contracts can decentralize upgrade permissions and reduce the risk of abuse of privileges by developers.

5. Protocol Management Control Momentum Safe can be used to manage key features of the protocol, such as parameter adjustments, emergency stops, and community reward changes.

The Security and Scalability of Momentum Safe

Momentum Safe adopts the Aptos native multi-signature transaction standard and combines on-chain storage to save the data required for multi-signature transactions. Its transaction process is as follows:

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 collect enough signatures will submit the aggregated signature through Aptos core multi-ed25519.
5. The blockchain verifies and completes Multi-ed25519 transactions.
6. MOVE VM executes the entry function specified by the user

Features of Momentum Safe

In addition to the basic functions of the Multi-signature Wallet, Momentum Safe also plans to support the following features:

1. Complete interoperability: Can interact with any Dapp
2. Notification Service: Real-time account activity notifications
3. DAPP Store: Recommended protocols and tools based on user needs.
4. Cross-chain integration: Introduce cross-chain assets to optimize the Aptos user experience.
