About this project

The project aims to provide a solution for KOL(influencer) to handle general collaboration with other parties on digital contract utilizing ZK contract with AI audit.

1. ZK function can increase privacy protection on contract verification.
2. AI audit an help user to detect the potential risk in contract.

Actually, KOL may not have professional knowledge on how to prepare the contract, check the contract content in order to protect their benefit.

Moreover, digital contract can be one of the digital asset, and move language can create more value on digital asset protection and usage.

Furthermore, ZK function can help verify the contract and personal identity with better privacy protection.

Achievement

Status (Updating)

20240706

1. Optimize the smart contract (move)
2. Add connect function (allows users to log in with a Google ID without needing an MPC Network, Magic Links, or Windows passkey) 20240707
3. update "@aptos-labs/wallet-adapter-react": "^3.4.3"

20240721

1. add new fucntion - check contract list (which is created by other and is waiting you [expected signer] for sign)

20240722

1. function optimization - check contract list. User can input the address of contract creator and check the contract list. if you are one of expected signer from teh contract, you will see the contract in contract list.
