x402 SDK Project Scaffold

Create a complete TypeScript/Node.js project scaffold for building on the Bankr x402 SDK.

Process

1. Determine project type - If $ARGUMENTS specifies a type, use it. Otherwise, ask the user.

   Load the x402-project-templates skill for available types:

   • bot - Automated trading bot, price monitor, portfolio rebalancer, scheduled task
   • web-service - HTTP API that wraps Bankr SDK for mobile apps or integrations
   • dashboard - Web UI for portfolio tracking, swap interface, monitoring
   • cli - Command-line tool for Bankr operations

2. Ask for project details:

   • Project name (kebab-case, e.g., my-trading-bot)
   • Brief description of what it will do
   • Any specific SDK operations it will use (swaps, transfers, queries, NFTs, leverage)
   • Package manager preference: bun (recommended - faster) or npm

3. Create project structure:

   • Load x402-project-templates skill for the directory structure
   • Load x402-client-patterns skill for common files and client code
   • Create all directories using mkdir -p
   • Write each file using the Write tool
   • Customize based on user's description

4. Explain next steps:

   • How to set up the payment wallet (private key with USDC on Base)
   • How to run the project (use selected package manager: bun install && bun dev or npm install && npm run dev)
   • What to customize first based on their use case

Skills to Load

Core Skills (always load):

• x402-project-templates - Directory structures for each project type
• x402-client-patterns - bankr-client.ts and common files (package.json, tsconfig.json, .env.example, .gitignore)
• sdk-capabilities - SDK operation reference

Capability Skills (load based on project purpose):

• sdk-token-swaps - For trading bots: swap patterns, approval handling
• sdk-transaction-builder - For custom transfers, NFT ops, bridges
• sdk-balance-queries - For dashboards: portfolio queries, balance tracking
• sdk-wallet-operations - For multi-wallet setups
• sdk-job-management - For advanced: job polling, cancellation

Implementation Notes

• Create all directories first using mkdir -p
• Write each file using the Write tool
• Include helpful comments in generated code
• Generate a README.md with setup instructions and usage examples
