X-Safe: Cross-Chain Gnosis Safe Multi-Sig Optimization

XSafe | ETHGlobal New York 2023

WINNER OF 🥉 Safe — Best Use of Safe{Core},🏆 ETHGlobal New York 2023 Finalist

Overview

X-Safe aims to optimize the Gnosis Safe multi-sig framework for multi-chain transactions. It simplifies identical administrative functions on multiple blockchains by enabling single signature propagation and transaction broadcasting.

Technical Features

  • Gnosis Safe Integration: Inherits security measures and features from Gnosis Safe, adding multi-chain capabilities.
  • Single Signature Propagation: Eliminates need for individual signing on each chain.
  • Single Transaction Broadcast: Executes identical smart contract methods or admin functions on multiple chains.
  • Chain Agnostic: Compatible with any blockchain supported by Gnosis Safe.

Workflow

  1. Initialization: One-time custom module setup via Gnosis Safe UI.
  2. Transaction Creation: Multi-chain transaction initiated.
  3. Signature Generation: Transaction signed via X-Safe interface.
  4. Signature Propagation: Signatures sent to corresponding Gnosis Safe contracts.
  5. Transaction Execution: Triggered on all chains based on user settings.

Use Cases

  • Smart contract deployment on multiple chains.
  • DAO governance parameter updates across multiple chains.
  • Cross-chain asset management.

Benefits

  • Efficiency: Reduces time for multi-chain ops.
  • Cost-Effectiveness: Cuts down transaction costs.
  • Security: Leverages Gnosis Safe security features, adds cross-chain functionality.

By adopting X-Safe, developers can make their cross-chain operations more efficient, secure, and cost-effective.
