Description

Integrate Safe (Gnosis Safe) SDK to enable collaborative transaction building and signing through the canvas interface.

Overview

Allow CryptID users to create, propose, and sign Safe multisig transactions visually on the canvas. Multiple signers can collaborate in real-time to approve transactions.

Dependencies

  • Requires task-007 (Web3 Wallet Linking) to be completed first
  • Users must link their Safe wallet or EOA that is a Safe signer

Technical Approach

  • Use Safe{Core} SDK for transaction building and signing
  • Create TransactionBuilderShape for visual tx composition
  • Use Safe Transaction Service API for proposal queue
  • Real-time signature collection via canvas collaboration

Features

  1. Safe Linking - Link Safe addresses (detect via ERC-1271)
  2. TransactionBuilderShape - Visual transaction composer
  3. Signature Collection UI - See who has signed, who is pending
  4. Transaction Queue - View pending transactions for linked Safes
  5. Execution - Execute transactions when threshold is met

Visual Transaction Builder Capabilities

  • Transfer ETH/tokens
  • Contract interactions (with ABI import)
  • Batch transactions
  • Scheduled transactions (via delay module)

Collaboration Features

  • Real-time signature status on canvas
  • Notifications when signatures are needed
  • Discussion threads on pending transactions

Acceptance Criteria

  • #1 Install and configure Safe{Core} SDK
  • #2 Implement ERC-1271 signature verification for Safe linking
  • #3 Create TransactionBuilderShape for visual tx composition
  • #4 Build signature collection UI with real-time updates
  • #5 Display pending transaction queue for linked Safes
  • #6 Enable transaction execution when threshold is met
  • #7 Support basic transfer and contract interaction transactions
