Add diagnostic sandboxes for AI, blockchain, and Web3 interactions by Copilot · Pull Request #16 · lippytm/Web3AI

Copilot · 2026-01-24T12:04:54Z

Adds isolated testing environments for transparent validation of AI models, blockchain connectivity, and Web3 wallet interactions.

Implementation

Backend Sandboxes (sandboxes/backend/)

ai_diagnostics.py - AI model connection testing, config validation, custom prompt execution
blockchain_simulation.py - RPC validation, network queries, balance checks

Frontend Sandboxes (sandboxes/frontend/)

Web3Sandbox.tsx - Interactive wallet connection, account/balance display, network detection
AIChatSimulation.tsx - Backend API connectivity testing, message simulation

Smart Contract Sandboxes (sandboxes/contracts/)

SimpleStorage.sol - Test contract with event emission
SimpleStorage.test.js - Deployment diagnostics, gas usage reporting, multi-user simulation
deploy_sandbox.js - Transparent deployment with network diagnostics

Automation

quickstart.sh - Interactive setup for all sandbox environments

Usage

# Run backend diagnostics
python sandboxes/backend/blockchain_simulation.py

# Test AI with custom prompt
python sandboxes/backend/ai_diagnostics.py --prompt "Your prompt here"

# Quick start all sandboxes
cd sandboxes && ./quickstart.sh

All sandboxes emit structured diagnostic output showing configuration, connection status, and operation results. See sandboxes/README.md for detailed usage.

Original prompt

I need to add Sandboxes to my repository for diagnostics and simulations transparencies.

✨ Let Copilot coding agent set things up for you — coding agent works faster and does higher quality work when set up for your repo.

+            model=settings.model_name,
+            api_key=settings.openai_api_key.get_secret_value(),


The code calls settings.openai_api_key.get_secret_value() but the Settings class defines openai_api_key as a plain string type, not a SecretStr. This will cause an AttributeError at runtime. Change this to just settings.openai_api_key to match the actual Settings implementation.

Suggested change

api_key=settings.openai_api_key.get_secret_value(),

api_key=settings.openai_api_key,

+    echo "export { default } from '@/../sandboxes/frontend/AIChatSimulation';" > app/sandbox/ai/page.tsx


The import path @/../sandboxes/frontend/Web3Sandbox will not work because the @ alias is not configured in the Next.js project (no next.config.js with path aliases). Use a relative path instead, such as ../../../sandboxes/frontend/Web3Sandbox or configure the @ alias in tsconfig.json and next.config.js to point to the project root or frontend directory.

+    function increment() public {
+        uint256 oldValue = storedData;
+        storedData += 1;
+        emit ValueChanged(oldValue, storedData, msg.sender);
+    }


The increment() function doesn't handle the case when storedData is at its maximum value (type(uint256).max). While Solidity 0.8+ will revert on overflow, consider adding an explicit check or documenting this behavior for transparency in a diagnostic sandbox. For example: require(storedData < type(uint256).max, "Cannot increment beyond maximum value");

+  console.log("\n" + "=".repeat(60));
+  console.log("Testing Contract Interaction");
+  console.log("=" .repeat(60));


The string concatenation is incorrect. The expression "=" .repeat(60) will result in "=.repeat(60)" instead of a repeated string. Use "=".repeat(60) without the space between the string and the method call.

The Solidity version ^0.8.20 in SimpleStorage.sol is inconsistent with the hardhat configuration which specifies 0.8.24 (see contracts/hardhat.config.js:6). While ^0.8.20 will work with 0.8.24, for consistency consider using ^0.8.24 to match the existing Lock.sol contract and hardhat configuration.

The SPDX license identifier is "ISC" in SimpleStorage.sol but "MIT" in the existing Lock.sol contract (see contracts/contracts/Lock.sol:1). For consistency across the codebase, consider using the same license identifier. The README.md also indicates the project uses ISC license (line 437).

+        return;
+      }

+      const accounts = await window.ethereum.request({


The code uses window.ethereum without TypeScript type definitions, which will cause TypeScript errors. Consider adding a global type definition file (e.g., types/window.d.ts) with the following:

interface Window { ethereum?: { request: (args: { method: string; params?: any[] }) => Promise<any>; isMetaMask?: boolean; }; }

This is a common pattern in Web3 projects to properly type the MetaMask provider.
