Darwin
Self-evolving e-commerce agents in crypto, where wallet balance is their lifeforce.
About
Description： DaVinci is the self-evolving engine within the Darwin Agents e-commerce system, creating a fully autonomous e-commerce ecosystem. Within this ecosystem, five categories of Agents collaborate seamlessly: - Supply Chain Management Agent - Risk Management Agent - Inventory Agent - Marketing & Sales Agent - Store Management Agent Together, these Agents drive the vitality of an online store—brand positioning, operational strategy, and action tracking. The store’s performance becomes the foundation for Agents’ self-evolution. Evolution Mechanism: 1. Lifecycle: Each online store starts with a 3-month lifecycle. 2. Data Pipeline: Weekly performance summaries (wallet balance, agent actions, and costs) feed into the system for self-improvement. 3. Evaluation: More resources are allocated to high-performing Agents, while underperformers are phased out. 4. Replication & Mutation: Every month, an Agents team is cloned with slight variations in branding or operational strategy, creating a new store entity. 5. Lifeforce Rule: After three months, if the wallet retains a balance, the lifecycle extends; if not, the store ceases to exist (0 = death, >0 = life). Technology & Security: 1. Dynamics Wallet Balance = Lifeforce: The wallet directly reflects the store’s ability to survive. 2. Flow Tracking: All agent actions are recorded on-chain, ensuring transparency and immutability. 3. Coinbase x402 Middleware: Provides Agents with API payments, service access, and wallet integration, enabling greater autonomy. 4. OpenSea Behavior Analysis: DaVinci transforms user behaviors into NFTs, building a verifiable identity layer and an AI–human interaction memory that Agents can analyze and leverage for continuous self-improvement. DaVinci establishes a fully self-operating e-commerce ecosystem run entirely by Agents, where all decisions, behaviors, and evolutions are powered by on-chain data—and the wallet balance stands as the ultimate symbol of life.
How it's made
## 🔨 Build Process & Implementation Journey ### Phase 1: Foundation & Architecture **Core Infrastructure Setup** ```bash # Project initialization with modern stack npx create-next-app@latest davinci --typescript --tailwind --app cd davinci pnpm install # Essential dependencies for Web3 integration pnpm add @dynamic-labs/sdk-react-core @dynamic-labs/ethereum pnpm add wagmi viem @tanstack/react-query pnpm add @ai-sdk/react @ai-sdk/openai ``` **Dynamic.xyz Integration Implementation** - Configured Dynamic SDK with environment ID `0b7822a0-f446-4987-87f9-83b179f422e1` - Implemented multi-chain wallet support (Ethereum, Solana, Bitcoin, Flow) - Built visitor mode with 5-message limitation for user onboarding - Integrated Wagmi v2 for enhanced Ethereum interactions **Key Decision**: Chose Dynamic.xyz over other wallet solutions due to superior UX for non-crypto users and robust multi-chain support. ### Phase 2: AI Agent System Development **Multi-Agent Architecture Design** ```typescript // Manager Agent orchestration system interface AgentHierarchy { manager: ManagerAgent; specialized: { product: ProductAgent; marketing: MarketingAgent; crm: CRMAgent; pricing: PricingAgent; }; } ``` **Dify API Integration** - Implemented streaming chat interface with real-time tool execution tracking - Built conversation persistence system with localStorage + API sync - Created file upload system supporting images, documents, audio, video - Developed tool execution visualization with auto-collapse animations **Challenge Solved**: React Strict Mode causing duplicate tool executions - implemented deduplication with correlation IDs and processing guards. ### Phase 3: Flow EVM Blockchain Integration **Smart Contract Development** ```solidity // Custom listing sync contract on Flow EVM Testnet contract ForestMarketListingSync { struct Listing { string sku; uint256 price; address currency; address agent; uint256 timestamp; } mapping(string => Listing) public listings; event ListingSynced( string indexed sku, uint256 price, address currency, address indexed agent ); } ``` **Deployment Process** ```bash # Flow EVM Testnet deployment npx hardhat deploy --network flow-evm-testnet # Contract Address: 0xd2F523a0085781Aa8492eeA6E84F0152B2c26E8f ``` **Real-time Blockchain Sync Implementation** - Built SKU generation system with format `FM-CAT-EID123-001` - Implemented duplicate prevention with localStorage tracking - Created blockchain status indicators for user feedback - Developed automatic network switching to Flow EVM Testnet **Technical Innovation**: Solved duplicate blockchain syncs by implementing three-layer deduplication: 1. Message-level processing guards 2. SKU pattern checking 3. Transaction hash verification ### Phase 4: Autonomous Payment System (X402) **Coinbase X402 Integration Design** ```javascript // Conceptual autonomous payment flow class ManagerAgent { async monitorCredits() { const usage = await this.trackLLMUsage(); if (usage.remaining < threshold) { await this.purchaseCredits(); } } async purchaseCredits() { const payment = await coinbaseX402.createPayment({ recipient: 'openrouter.ai', amount: this.calculateOptimalAmount(), currency: 'USDC' }); return payment.execute(); } } ``` **Resource Management System** - Built credit monitoring dashboard for Manager Agent - Implemented cost optimization algorithms - Created payment history tracking - Developed automatic resource allocation between agents ### Phase 5: Integration Testing & Debugging (Week 6) **Critical Bug Fixes Implemented** 1. **Duplicate Blockchain Syncs**: Added processing guards and SKU deduplication 2. **Tool Execution Persistence**: Implemented multi-key storage strategy 3. **React Strict Mode Issues**: Added effect execution tracking 4. **State Management**: Fixed conversation loading and tool restoration **Testing Strategy** ```bash # Comprehensive testing approach pnpm test # Unit tests for core functions pnpm build # Production build verification pnpm lint # Code quality checks pnpm typecheck # TypeScript validation ``` **Live Demo Validation** - Successfully created "Cherry keyboard" listing with SKU `FM-ELE-3m3dm-001` - Verified real-time Flow EVM sync at contract address - Tested visitor mode limitations and authentication flow - Validated cross-browser compatibility and performance ### Key Technical Achievements 1. **Seamless UX**: Progressive Web3 onboarding that appeals to mainstream users 2. **Autonomous Operations**: Manager Agent with independent financial decision-making 3. **Transparency**: Complete audit trail of AI decisions on Flow EVM 4. **Scalable Design**: Modular agent system supporting future expansion
