X-Safe: Cross-Chain Gnosis Safe Multi-Sig Optimization
Overview: X-Safe is a solution designed to optimize the Gnosis Safe multi-signature (multi-sig) framework for multi-chain transactions. The core objective is to reduce the time and complexity involved in performing identical administrative functions on multiple blockchain networks. Through X-Safe, users can propagate a single signature and a single transaction across multiple chains, thereby reducing overhead and expediting workflows.
Use Cases: • Deploying identical smart contracts across multiple blockchains. • Updating governance parameters on DAOs that exist on multiple chains. • Cross-chain asset management for diversified portfolios.
Benefits: • Efficiency: Drastically reduces the time needed to perform multi-chain operations. • Cost-Effectiveness: Reduces transaction costs by eliminating the need for multiple signatures and transactions. • Security: Leverages the robust security features of Gnosis Safe, while adding cross-chain functionality.
By implementing X-Safe, developers can significantly streamline their cross-chain operations, making the system more efficient, secure, and cost-effective.
X-Safe: Technical Architecture for Enhanced Multi-Sig Functionality in Gnosis Safe Core Logic and Mechanics
God Contract: This is a custom Solidity contract module that interfaces with existing Gnosis Safe contracts. It alters the default Gnosis Safe logic in the following ways:
ChainID Removal: The contract omits the chainID from the signature payload, making the same signature valid across multiple blockchains.
Nonce Synchronization: A specialized mechanism within the contract synchronizes the nonces for each chain's corresponding Gnosis Safe contract, enabling a single signature to be used across multiple chains without nonce conflict.
Backend Logic: The backend is Python-based and designed to interact with the God Contract using Web3.py.
Signature and Transaction Propagation: Upon capturing specific events emitted by the God Contract, the backend logic propagates them to the corresponding Gnosis Safe contracts on all other integrated blockchains.
Key Features: Signature Condensation: By eliminating chain-specific elements like chainID and by synchronizing nonces, the system condenses multiple signatures into a single one, thus reducing both complexity and time.
Transaction Condensation: The architecture allows for gas costs across multiple chains to be consolidated and paid on a primary chain. This reduces user interactions from multiple confirmations to a single click.
By closely aligning with Gnosis Safe's existing structure while introducing specific enhancements like chainID removal and nonce synchronization, X-Safe offers a streamlined approach to multi-sig operations across multiple blockchains.
