feat: wallet mode — DeFi testing with MetaMask + Anvil fork#15
Conversation
Automated wallet/DeFi flow testing against MetaMask + Anvil mainnet fork: - setup-extension.mjs: download MetaMask from GitHub releases - setup-onboarding.mjs: automate MetaMask 13.x SRP import (CDP for LavaMoat bypass) - setup-anvil.mjs: start Anvil fork, seed 100 ETH + 10 WETH + 10k USDC - run-wallet-validation.mjs: orchestrate wallet case runs via CLI - DeFi cases: connect/swap/supply against Uniswap, Aave, 1inch, SushiSwap - Tangle cases: connect, stake, bridge flows - CLAUDE.md: document wallet patterns and setup commands
DApps use their own RPC endpoints (Infura, QuikNode, Tenderly, or
self-hosted on their own domain) for balance/contract reads. This adds
a Playwright context.route('**/*') interceptor that detects JSON-RPC
POST requests (eth_*/net_*/web3_* methods) and proxies them to the
configured wallet chain RPC URL (e.g. local Anvil fork).
Also adds configure-network.mjs to set MetaMask's default RPC endpoint
to Anvil via direct LevelDB modification, and the wallet:configure
npm script.
DeFi validation: 5/7 pass (all 5 connect cases, Uniswap swap).
…alog bypass - Inject DeFi-specific brain context on first turn when wallet mode is active (transaction flows, persistent widgets, token selection, cookie banners) - Make wallet address configurable via wallet.address config instead of hardcoded Anvil default — enables custom mnemonics and HD paths - Hybrid RPC interception: only forward user-specific calls (eth_getBalance, eth_call, eth_estimateGas with wallet addr) to Anvil; pool/protocol data goes to real endpoints - JSON-RPC normalization for non-standard dApp requests (Aave omits jsonrpc/id fields) - Persistent dialog bypass in recovery: skip generic modal recovery after 3+ consecutive turns with same dialog — fixes SushiSwap support widget loops - Auto-restart Anvil with fresh fork state in validation runner - Add RPC reverse proxy for MetaMask service worker interception - Expand wallet.md guide: architecture, DeFi patterns, RPC interception details, troubleshooting, "Testing Your Own EVM App" section - Validated 7/7 DeFi cases: Uniswap, Aave, 1inch, SushiSwap ($0.98, 267s)
All three workflows were failing on PRs: - ci.yml: missing Playwright browser install before test step - tier1-gate.yml: hard fail when OPENAI_API_KEY unavailable on forks/PRs - tier2-staging-gate.yml: hard fail when secrets unavailable on forks/PRs Now warns and skips gate steps when secrets are missing instead of failing.
…tests - Add .rpc-proxy-cert/ and .rpc-proxy.pid to .gitignore - Fix JSON injection in rpc-proxy.mjs error response (use JSON.stringify) - Fix dead code in cli.ts RPC normalization (flip spread order) - Extract DeFi brain context to module-level constant in runner.ts - Add 3 tests for persistent dialog bypass in recovery.ts

Summary
context.route('**/*')forwards only user-specific JSON-RPC calls (eth_getBalance, eth_call, eth_estimateGas containing wallet address) to Anvil — pool/protocol data goes to real endpoints for reliability. Includes JSON-RPC normalization for non-standard dApp formats (Aave omits jsonrpc/id fields)walletMode: true, injects crypto-specific guidance into the agent's first-turn context — transaction flows, persistent widget handling, token selection, cookie banner dismissalwallet.addressconfig option replaces hardcoded Anvil default — supports custom mnemonics/HD pathsdocs/guides/wallet.mdexpanded from config reference to full EVM testing playbook — architecture diagram, "Testing Your Own EVM App" section, RPC interception details, DeFi patterns, troubleshootingValidated: 7/7 DeFi cases pass (Uniswap, Aave, 1inch, SushiSwap — connect + swap/supply flows), $0.98 total, 267s.
