ZakoBox/ZakoPako

1. What is ZakoBox/ZakoPako?

ZakoBox (or ZakoPako for the dev community who's familiar with japanese anime and comics) is an all-in-one on-chain governance and fundraising platform specifically designed for open-source development teams. Born from the real needs of Project Airi's Core-Dev-DAO (ZakoDAO), we're solving the critical pain points that distributed developer teams face: fragmented collaboration tools, opaque fund management, and inefficient decision-making processes.

1. The Problem We're Solving

2.1 Open-source projects today struggle with:

• Fragmented Tools: Teams juggle between multiple platforms - GitHub for code, Discord for communication, separate tools for fundraising, different platforms for governance
• Funding Transparency Issues: Traditional donation platforms take high fees and provide little transparency about fund usage
• Governance Inefficiency: Decision-making is often informal, undocumented, and controlled by a few individuals
• Trust Barriers: Donors hesitate to contribute without clear visibility into how funds are managed and allocated

1. Why This Matters

Open source software powers the internet, but its maintainers often struggle with sustainable funding. ZakoBox bridges the gap between the traditional developer ecosystem and Web3, making it dead simple for projects to accept crypto donations while maintaining full transparency and team control. We're not just building another DAO tool - we're creating the financial infrastructure for the next generation of open-source development.

By removing barriers between donors and developers, automating tedious governance processes, and providing complete transparency, ZakoBox enables development teams to focus on what they do best: building amazing software.

How ZakoBox is gonna to be Built

1. Architecture Overview

We built ZakoBox with a modular, upgradeable architecture that separates concerns between on-chain treasury management, off-chain data aggregation, and user interface layers. The system is designed to be self-deployable by any team while maintaining security and ease of use.

1. Smart Contract Layer

2.1 Core Contracts:

• ZakoBox.sol: The main treasury contract that handles multi-token deposits, withdrawal logic with configurable thresholds, and milestone-based fund releases. We implemented a custom access control system that goes beyond simple Ownable patterns to support weighted voting among core team members.
• ZakoBoxFactory.sol: A factory pattern implementation that allows one-click deployment of new ZakoBox instances with pre-configured parameters. Each deployment is deterministic using CREATE2, allowing teams to predict their treasury address before deployment.
• ZakoBoxRegistry.sol: An on-chain registry that tracks all deployed ZakoBox instances, making it easy to discover and verify legitimate treasuries.

2.2 Technical Stack:

• Solidity 0.8.20+ for the latest security features and gas optimizations
• Hardhat 3.0.0+ as our development framework for its superior testing and debugging capabilities
• OpenZeppelin Contracts 5.0 for battle-tested implementations of ERC20, AccessControl, and ReentrancyGuard
• UUPS proxy pattern for upgradeability with reduced gas costs compared to transparent proxies

2.3 Notable Hacks:

• Custom multicall implementation that batches multiple operations (like distributing funds to multiple recipients) in a single transaction, reducing gas costs by up to 40%
• Innovative "lazy initialization" pattern where complex DAO parameters are only set when first used, saving deployment gas
• Signature aggregation system that allows collecting multisig approvals off-chain before executing on-chain, dramatically reducing transaction costs

1. Frontend Implementation

3.1 Tech Stack:

• Vue 3 with Composition API for reactive, maintainable component architecture
• TypeScript for type safety across the entire frontend codebase
• Vite for lightning-fast HMR and optimized production builds
• UnoCSS for atomic CSS with minimal bundle size
• Shadcn-vue for accessible, customizable UI components
• Pinia for state management with built-in devtools support

3.2 Web3 Integration:

• Wagmi/Viem for robust Ethereum interactions with automatic type generation from ABIs
• WalletConnect v2 for broad wallet compatibility
• Custom hooks for transaction management with optimistic updates and automatic retry logic
• IndexedDB for local caching of on-chain data to reduce RPC calls

1. Partner Technology Integrations

4.1 PYUSD Integration: We prioritized PYUSD as our primary payment method, implementing:

• Direct PYUSD transfer handlers in our smart contracts
• Automatic conversion estimation for non-USD donations
• Special gas optimization for PYUSD transfers using their specific transfer hooks
• Compliance-friendly transaction metadata storage for PYUSD payments

4.2 Blockscout SDK Integration:

• Deep integration with Blockscout's API for real-time transaction monitoring
• Custom dashboard components using Blockscout's data visualization tools
• Transaction history export functionality leveraging Blockscout's CSV generation
• Smart contract verification automation through Blockscout's API

4.3 GitHub Integration:

• OAuth2 flow for secure GitHub authentication
• Webhook listeners for repository events (new contributors, milestones, releases)
• Custom GitHub App that adds a "Donate with Crypto" button to repository pages
• Automatic contributor verification using GitHub's commit signature verification

4.4 Jumper (LI.FI) Integration (optional in MVP):

• Cross-chain swaps enabling donations from any chain to be consolidated in the treasury
• Automatic route optimization for best exchange rates
• Fallback mechanisms when bridge liquidity is low

1. The Hacky Parts Worth Mentioning

5.1 GitHub Action as Oracle: We created a novel approach where GitHub Actions serve as a pseudo-oracle for milestone completion. When a GitHub milestone is closed, it triggers an Action that calls our smart contract through a relayer, automatically releasing funds. This bridges the Web2/Web3 gap without expensive oracle infrastructure.

5.2 Gasless Donations for Small Contributors: We implemented a meta-transaction system where the DAO can sponsor gas fees for donations under $50, removing barriers for small contributors. The clever part: we batch these meta-transactions and execute them when gas prices are lowest, typically saving 60-80% on fees.

5.3 "Shadow Treasury" Pattern: We developed a dual-treasury system where urgent payments can be made from a "hot" wallet with lower thresholds, while the main treasury requires full multisig. The hot wallet automatically replenishes from the main treasury using a time-weighted average algorithm.

5.4 Progressive Decentralization Switch: Our contracts include a "training wheels" mode for new DAOs where certain administrative functions are initially controlled by a single admin, with automatic progression to full decentralization after set milestones (time-based or transaction volume-based).

5.5 Iframe-able Donation Widget: We built a sandboxed donation widget that any website can embed with a single line of code. The hacky part: it uses postMessage API to communicate with our main app while maintaining security, and automatically inherits the host site's color scheme using CSS custom properties.

1. Data Layer

6.1 On-chain Data:

• Events for every significant action (donations, withdrawals, proposals, votes)
• IPFS for storing large governance documents with on-chain hash verification
• ENS integration for human-readable treasury addresses

6.2 Off-chain Data:

• PostgreSQL for caching on-chain data and storing user preferences
• Redis for session management and real-time notification queuing
• IPFS pinning service for permanent storage of governance artifacts

1. Security Measures

7.1 Smart Contract Security:

• Comprehensive test suite with 95%+ code coverage
• Fuzzing tests using Foundry for edge case discovery
• Slither and Mythril for automated vulnerability scanning
• Manual review focusing on reentrancy, overflow, and access control

7.2 Frontend Security:

• Content Security Policy (CSP) headers preventing XSS attacks
• Subresource Integrity (SRI) for all external dependencies
• Input validation and sanitization using DOMPurify
• Rate limiting on all API endpoints

1. Development Workflow

8.1 CI/CD Pipeline:

• GitHub Actions for automated testing on every PR
• Automatic contract deployment to testnets on merge to main
• Frontend preview deployments using Vercel
• Automated security scanning using Dependabot and Snyk

8.2 Monitoring:

• Custom Grafana dashboards tracking treasury metrics
• Sentry for error tracking and performance monitoring
• On-chain monitoring using Tenderly for anomaly detection

1. Performance Optimizations

• Lazy loading of heavy components (charts, analytics)
• Service Worker for offline capability and caching
• GraphQL with DataLoader pattern for efficient data fetching
• Contract optimization reducing deployment costs by 30% through bytecode optimization

1. The Ideal Output

By carefully selecting and integrating these technologies, we are going to create a platform that:

• Deploys a fully functional DAO treasury in under 30 seconds
• Handles donations from both crypto-native and traditional GitHub users
• Processes governance decisions transparently on-chain
• Scales to support thousands of DAOs without infrastructure changes

The most innovative aspect is how we've bridged the Web2 developer world with Web3 infrastructure, making it feel native to both ecosystems. Developers can continue using GitHub while benefiting from blockchain's transparency and security, and crypto users get a familiar DeFi experience with additional developer-focused features.

This architecture allows any team to fork and deploy their own instance while still benefiting from our shared infrastructure for things like cross-chain bridging and GitHub integration. It's truly decentralized, not just in governance, but in deployment and operation.
