Multisig Legacy

The Multisig Legacy type use Safe wallet infrastructure, leveraging the battle-tested security of the popular estalished platform. Once activated, an inheritance will provides pre-designated beneficiaries with full wallet permission by adding the beneficiaries as co-signers to a multisig Safe wallet, leveraging the battle-tested security of an established wallet infrastructure.

Beneficiaries will become co-owners of the Safe wallet, and can take complete control of the account. They claim the Safe wallet’s staked assets from other platform/protocol (the assets are not stored directly inside the wallet) and other potential non-assets properties, like the reputation, bonus points/rewards, airdrop, etc.

The owner of the legacy can create, edit or delete a contract through both 10102's Digital Inheritance application, as well as through their Safe account. Similarly, beneficiaries can activate a legacy contract through both the 10102 app and the Safe platform.

Flow of the Multisig Legacy

Create a multisig legacy contract

• The legacy owner can create a Safe wallet in https://app.safe.global. The legacy is set as a legacy contract using Safe Proxy.

• After setting the legacy contract in Safe Proxy, the will owner can set guard in https://app.safe.global or in the Digital Inheritance's site. The system uses Set Guard Function of SafeGuard.

• The legacy owner can set module in https://app.safe.global or in the Digital Inheritance's site using Set Module function.

• After setting guard and module, the legacy owner can configure will details including asset, beneficiaries and time to activation since last outgoing transaction.

• Co-signers of the Safe Wallet will need to sign a transaction to finalize creating the legacy contract. Once the minimum number of signatures required in the Safe Wallet is met, the legacy contract is created.

Edit a multisig legacy contract

• After creating the legacy contract successfully, the owner can add more beneficiaries and/or adjust the time to activation.

• Co-signers of the Safe Wallet will need to sign a transaction to finalize editing the legacy contract. Once the minimum number of signatures required in the Safe Wallet is met, the contract is updated.

Delete a multisig legacy contract

• After creating legacy contract successfully, the owner can delete will.

• Co-signers of the Safe Wallet will need to sign a transaction to finalize deleting the legacy contract. Once the minimum number of signatures required in the Safe Wallet is met, the legacy contract is deleted.

Activate a multisig legacy contract

• Any of the designated beneficiaries can make a call to activate a legacy contract to the Safe module contract and pay a gas fee.

• SafeModule check the latest timestamps transaction in SafeGuard to see if enough time has passed.

• If enough time has passed, Safe Module will execute execTransactionFromModule to SafeProxy ( the legacy contract)

• The beneficiaries will be added as new co-signers to the Safe Wallet that contains the inheritance. The minimum number of signatures required to initiate a transaction in the Safe wallet remains unchanged.
