The RIF Multisig - Gnosis Summary

Gnosis Safe solution consists of four main modules. It currently supports Ethereum and other EVM networks (Rinkeby, xDai, EWC, Volta), including Rootstock (RSK).

• A) The smart contracts

  • The suite of the smart contracts has the following structure:

    • A Gnosis Safe implementation. It implements functionality for:
      • Managing owners⁽¹⁾ and threshold⁽²⁾
      • Submitting signatures or transactions pre-signed off-chain
      • Rejecting transactions
      • Allowing gas payments with tokens (relayed transactions)
      • Enhanced for adding modules ⁽³⁾
    • A proxy factory contract that deploys proxies using Gnosis Safe implementation in two transactions

    

    • Repo: https://github.com/gnosis/safe-contracts
    • Deployments: https://github.com/gnosis/safe-deployments/tree/main/src/assets/v1.2.0
    • ⁽¹⁾Owners: accounts enabled to sign and approve/reject multisig transactions
    • ⁽²⁾Threshold: the number of owners that need to sign to approve and send a transaction
    • ⁽³⁾Those functionalities are not included in this project
• B) Transaction service

  • The transaction service exposes a REST API for multisig (and other features used in the UI). It collects all the multisig information using trace_transaction and trace_blocks. Furthermore, it allows collecting off-chain signatures and retrieving multisig pending transactions.

• C) The Core SDK
  • A Javascript SDK that currently implements most of the functionalities required.

• D) The UI

  • Users can log in with an existent Gnosis Safe, or they can create a new one. It allows to view and to send assets, to show the transaction list, and to edit the safe settings properties (owners, threshold)
