What is tweazy CLAUDE.md?

Project instructions for Tweazy, a Next.js application that charges 0.01 USDC per AI query using Web3 payments. They describe development commands, the application structure, wallet handling, and payment flow.

Running, building, and linting Tweazy; initializing its configuration; and changing its AI payment, wallet, network, and API systems.

They help an agent work within the project's existing architecture instead of guessing how its servers, payments, wallets, and configuration fit together.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00813	$0.00813
Opus 5.5	$0.00325	$0.00325
Sonnet 5.5	$0.00163	$0.00163
Haiku 4.5	$0.00081	$0.00081

Security

Grade A, and why

tweazy CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

npm run init - Initialize Tambo configuration

Project Architecture

Tweazy is a Next.js application that demonstrates pay-per-use AI with Web3 payments using x402 protocol, MCP (Model Context Protocol), and CDP Smart Wallets. Users pay 0.01 USDC per AI query.

Core Systems

Payment System (src/lib/payment.ts):

Universal payment handling for both Smart Wallets (CDP) and external wallets
Paymaster integration for gas sponsorship on Smart Wallets
USDC transfers on Base network (testnet/mainnet)

Wallet Architecture:

Smart Wallets (src/lib/smart-wallet.ts, src/lib/cdp-wallet.ts): CDP-based passkey authentication with gas sponsorship
External wallets: wagmi integration for MetaMask, Coinbase Wallet, etc.
Dual-wallet context in src/components/WalletProvider.tsx

Network Configuration (src/lib/config.ts):

Environment-based testnet/mainnet switching via NEXT_PUBLIC_NETWORK_MODE
Base Sepolia (testnet, default) and Base Mainnet support
Network-specific USDC contracts and RPC endpoints
Centralized config with secrets in environment variables only

AI Integration:

Tambo AI framework for generative UI with React component registry
MCP protocol support for extensible AI functionality
Every AI query is payment-gated in EnhancedMessageInput, which opens the payment flow before the request is sent
Dynamic component rendering based on AI responses

API Routes Structure

POST /api/cdp/create-wallet - Create CDP Smart Wallet
POST /api/cdp/balance - Check USDC balance
POST /api/cdp/transfer - Not implemented; returns 501 (503 when CDP is unconfigured). Mock transfers are available only behind TWEAZY_ALLOW_MOCK_PAYMENT=1.
POST /api/cdp/fund-wallet - Fund wallet with testnet tokens
POST /api/paymaster - Handle paymaster gas sponsorship

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
