Build MCP Server: NEAR Multi-Sig Wallet for Claude

Description

## Overview
Create an MCP server for managing NEAR multi-signature wallets - creating proposals, gathering signatures, and executing transactions.

## Why This Matters
DAOs and teams need multi-sig security. Claude can help manage the complexity of multi-party approvals.

## Technical Requirements

### Multi-Sig Operations
```typescript
// 1. create_multisig - Set up new multi-sig account
// 2. add_proposal - Create transaction proposal
// 3. approve_proposal - Add signature to proposal
// 4. check_proposal_status - See who has signed
// 5. execute_proposal - Execute when threshold met
// 6. list_pending - Show awaiting proposals
```

### Security Features
- Clear threshold requirements
- Signer verification
- Timeout handling
- Proposal expiration

## Deliverables
1. **Multi-sig MCP server**
2. **Full proposal lifecycle support**
3. **Security documentation**
4. **Integration with common multi-sig contracts**

## Budget: 15 NEAR
Complex security features = higher budget.
