+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Integrate Snapshot.js SDK for off-chain governance voting through the canvas interface.
+
+## Overview
+Enable CryptID users with linked wallets to participate in Snapshot governance votes directly from the canvas. Proposals and voting can be visualized as shapes on the canvas.
+
+## Dependencies
+- Requires task-007 (Web3 Wallet Linking) to be completed first
+- User must have at least one linked wallet with voting power
+
+## Technical Approach
+- Use Snapshot.js SDK for proposal fetching and vote submission
+- Create VotingShape to visualize proposals on canvas
+- Support EIP-712 signature-based voting via linked wallet
+- Cache voting power from linked wallets
+
+## Features
+1. **Proposal Browser** - List active proposals from configured spaces
+2. **VotingShape** - Canvas shape to display proposal details and vote
+3. **Vote Signing** - Use wagmi's signTypedData for EIP-712 votes
+4. **Voting Power Display** - Show user's voting power per space
+5. **Vote History** - Track user's past votes
+
+## Spaces to Support Initially
+- mycofi.eth (MycoFi DAO)
+- Add configuration for additional spaces
