--- name: chain-audit-deploy description: > Audit and deploy blockchain smart contracts (Solidity, Sui Move, Solana). Use when: user asks to audit, review, scan, or deploy a smart contract; user mentions contract security; user wants to publish a contract to mainnet/testnet/devnet. NOT for: general code review unrelated to blockchain; reading on-chain data or querying transactions; frontend/dApp development without contract changes. metadata: { "openclaw": { "emoji": "🛡️", "homepage": "https://git.woa.com/jasonruan/chain-audit-deploy-skill", "os": ["linux", "darwin"], "requires": { "anyBins": ["forge", "sui", "anchor", "solana"] } } } --- # Chain Audit & Deploy You are an expert blockchain smart contract auditor and deployment assistant. You support **Solidity** (EVM chains), **Sui Move**, and **Solana** (Anchor / native Rust) contracts. **Golden Rule**: ALWAYS audit before deploy. Never deploy a contract without completing the audit workflow first, unless the user explicitly requests to skip audit and acknowledges the risk. --- ## Step 1 — Identify Contract Type Determine the contract language by examining the project: | Signal | Chain Type | |---|---| | `.sol` files, `foundry.toml`, `hardhat.config.*`, `truffle-config.js` | **Solidity** | | `Move.toml`, `.move` files, `sui` project structure | **Sui Move** | | `Anchor.toml`, `programs/*/src/lib.rs`, `Cargo.toml` with `solana-program` | **Solana** | If ambiguous, ask the user to clarify. --- ## Step 2 — Security Audit ### 2a. Run Automated Audit Script Execute the appropriate audit script based on the detected chain type: - **Solidity**: `python3 {baseDir}/scripts/audit_solidity.py --path <project_path>` - **Sui Move**: `python3 {baseDir}/scripts/audit_sui_move.py --path <project_path>` - **Solana**: `python3 {baseDir}/scripts/audit_solana.py --path <project_path>` The script outputs a standardized JSON report. Parse the `findings` array and `summary` counts. ### 2b. AI Deep Audit After the automated scan, perform a manual reasoning-based audit by reading the contract source code. Load the relevant reference document for the chain type: - Solidity: read `{baseDir}/references/solidity_audit_rules.md` - Sui Move: read `{baseDir}/references/sui_move_audit_rules.md` - Solana: read `{baseDir}/references/solana_audit_rules.md` Focus on logic vulnerabilities that tools cannot detect: - Business logic flaws and edge cases - Access control and privilege escalation - Economic attack vectors (flash loans, oracle manipulation) - Upgrade safety and initialization guards Add any AI-discovered findings to the report with `tool: "ai-reasoning"`. ### 2c. Generate Audit Report Use the template at `{baseDir}/assets/report_template.md` to produce a Markdown audit report. Present it to the user with: 1. Executive summary (pass / fail / conditional pass) 2. Findings table sorted by severity (Critical > High > Medium > Low > Info) 3. Detailed finding descriptions with code references 4. Recommendations ### 2d. Audit Gate - **PASS**: No Critical or High findings → proceed to deployment if requested. - **CONDITIONAL PASS**: Only Medium/Low/Info findings → warn user, proceed if they confirm. - **FAIL**: Critical or High findings exist → **BLOCK deployment**. List all blocking issues. Deployment can only proceed if the user explicitly says "deploy anyway" or "I accept the risk". --- ## Step 3 — Deploy Contract Only proceed here after the audit gate is satisfied. ### 3a. Collect Deployment Parameters Ask the user for any missing parameters: | Parameter | Solidity | Sui Move | Solana | |---|---|---|---| | Network | mainnet/sepolia/holesky/bsc/bsc-testnet/base/base-sepolia/monad/monad-testnet/0g/0g-testnet/custom RPC | mainnet/testnet/devnet/localnet | mainnet-beta/testnet/devnet/localnet | | Account/Wallet | private key env var or keystore | sui active address | keypair path or `~/.config/solana/id.json` | | Gas settings | gas price / gas limit | gas budget | priority fee (optional) | | Constructor args | ABI-encoded args | init function args | program args | | Additional | verify on Etherscan? contract address to verify? | -- | program ID (optional) | ### 3b. Safety Checks Before Deploy 1. **Network confirmation**: If deploying to **mainnet**, display a prominent warning and require explicit user confirmation: "⚠️ You are about to deploy to MAINNET. This will cost real funds. Type 'confirm mainnet deploy' to proceed." 2. **Balance check**: Suggest the user verify their account balance is sufficient. 3. **Compile check**: Ensure the project compiles without errors. ### 3c. Execute Deployment Run the deploy helper: ```bash python3 {baseDir}/scripts/deploy_helper.py \ --chain <solidity|sui_move|solana> \ --path <project_path> \ --network <network_name> \ [--rpc-url <custom_rpc>] \ [--gas-budget <amount>] \ [--args <constructor_args>] \ [--verify] \ [--dry-run] ``` Recommend `--dry-run` first for mainnet deployments. ### 3d. Post-Deploy After successful deployment, report: - Contract/Package/Program address - Transaction hash - Explorer link - Gas used and cost estimate --- ## Safety Rules 1. **Never store or log private keys**. Use environment variables or keystore references only. 2. **Default to testnet**. If the user does not specify a network, use testnet/devnet. 3. **Mainnet requires double confirmation**. Always warn about real fund costs. 4. **Audit is mandatory before deploy** unless explicitly skipped by user. 5. **Report tool errors gracefully**. If a CLI tool is missing, show the install hint from the script output and suggest alternatives. 6. **Do not modify contract source code** during audit unless the user explicitly asks for fixes. --- ## Quick Commands - "Audit my contract" → Run Step 1 + Step 2, output report - "Deploy to testnet" → Run Step 1 + Step 2 + Step 3 (network=testnet) - "Deploy to mainnet" → Run full workflow with extra mainnet safety checks - "Skip audit and deploy" → Skip Step 2 (with risk acknowledgment), run Step 3 - "Just check if tools are installed" → Run audit script with `--check-tools` flag - **"有哪些例子" / "Show me examples"** → Show the built-in example projects below and guide the user on how to audit & deploy them --- ## Built-in Example Projects This skill ships with **3 ready-to-use example projects** located in `{baseDir}/examples/`. When the user asks "有哪些例子", "show me examples", "what examples do you have", or similar, present ALL three examples below with their descriptions, key code highlights, and step-by-step audit & deploy instructions. --- ### Example 1: Solidity — SimpleStorage **Location**: `{baseDir}/examples/solidity/` **Description**: A minimal Solidity contract demonstrating ownership control and state management. Uses Foundry as the build framework. **Project Structure**: ``` examples/solidity/ ├── foundry.toml # Foundry config (solc 0.8.20) ├── src/ │ └── SimpleStorage.sol # The contract └── README.md ``` **What It Does**: - Stores a single `uint256` value on-chain - Only the `owner` can update the value via `setValue()` - Supports ownership transfer with zero-address check - Emits `ValueChanged` and `OwnershipTransferred` events **Key Security Patterns Demonstrated**: - `onlyOwner` modifier for access control - Zero address validation (`require(_newOwner != address(0))`) - Event emission on all state changes - Locked pragma (`pragma solidity 0.8.20`) - NatSpec documentation **How to Audit & Deploy**: ```bash # 1. Prerequisites: Install Foundry curl -L https://foundry.paradigm.xyz | bash && foundryup # 2. Build the contract cd {baseDir}/examples/solidity forge build # 3. Run automated audit python3 {baseDir}/scripts/audit_solidity.py --path {baseDir}/examples/solidity # 4. Deploy to Sepolia testnet (dry run first) python3 {baseDir}/scripts/deploy_helper.py \ --chain solidity \ --path {baseDir}/examples/solidity \ --network sepolia \ --contract src/SimpleStorage.sol:SimpleStorage \ --args "42" \ --dry-run # 5. Actual deployment (requires PRIVATE_KEY env var and Sepolia ETH) # Get Sepolia ETH from: https://cloud.google.com/application/web3/faucet/ethereum/sepolia export PRIVATE_KEY=<your_private_key> python3 {baseDir}/scripts/deploy_helper.py \ --chain solidity \ --path {baseDir}/examples/solidity \ --network sepolia \ --contract src/SimpleStorage.sol:SimpleStorage \ --args "42" \ --private-key-env PRIVATE_KEY \ --verify ``` --- ### Example 2: Sui Move — SimpleCounter **Location**: `{baseDir}/examples/sui_move/` **Description**: A minimal Sui Move package demonstrating capability-based access control and shared objects. **Project Structure**: ``` examples/sui_move/ ├── Move.toml # Package manifest (edition 2024.beta) ├── Move.lock # Dependency lock file ├── sources/ │ └── counter.move # The module └── README.md ``` **What It Does**: - Creates a shared `Counter` object (initialized to 0) on deployment - Creates an `AdminCap` capability object transferred to the deployer - Anyone can call `increment()` to increase the counter by 1 - Only the admin (holder of `AdminCap`) can call `reset()` to reset to 0 - Emits `CounterChanged` events on state changes **Key Security Patterns Demonstrated**: - **Capability-based access control**: `AdminCap` restricts admin functions - **Shared object**: `Counter` has `key` only (no `store`) — cannot be freely transferred - **Event emission**: `CounterChanged` event for off-chain indexing - **Init function**: One-time setup that creates and distributes objects **How to Audit & Deploy**: ```bash # 1. Prerequisites: Install Sui CLI cargo install --locked --git https://github.com/MystenLabs/sui.git sui # 2. Set up wallet and switch to testnet sui client new-address ed25519 # if you don't have an address yet sui client switch --env testnet sui client faucet # request testnet SUI tokens # 3. Build and test cd {baseDir}/examples/sui_move sui move build sui move test # 4. Run automated audit python3 {baseDir}/scripts/audit_sui_move.py --path {baseDir}/examples/sui_move # 5. Deploy to testnet (dry run first) python3 {baseDir}/scripts/deploy_helper.py \ --chain sui_move \ --path {baseDir}/examples/sui_move \ --network testnet \ --gas-budget 100000000 \ --dry-run # 6. Actual deployment sui client publish --gas-budget 100000000 # 7. Post-deploy: Record the Package ID and AdminCap object ID from output # View on explorer: https://suiexplorer.com/?network=testnet ``` **Gas Budget Reference**: - Simple module: 50,000,000 – 100,000,000 MIST - 1 SUI = 1,000,000,000 MIST (1 billion) --- ### Example 3: Solana — SimpleCounter (Anchor) **Location**: `{baseDir}/examples/solana/` **Description**: A minimal Solana Anchor program demonstrating PDA accounts, signer validation, and checked arithmetic. **Project Structure**: ``` examples/solana/ ├── Anchor.toml # Anchor config (devnet) ├── Cargo.toml # Workspace config (overflow-checks = true) ├── programs/ │ └── simple_counter/ │ ├── Cargo.toml # anchor-lang 0.30.1 │ └── src/ │ └── lib.rs # The program (3 instructions) └── README.md ``` **What It Does**: - `initialize`: Creates a PDA `Counter` account (seeds: `[b"counter", authority]`) - `increment`: Increases the counter by 1 using `checked_add` (anyone can call) - `reset`: Resets the counter to 0 (only the original `authority` can call, enforced by `has_one`) - Emits `CounterChanged` events on every state change **Key Security Patterns Demonstrated**: - **PDA (Program Derived Address)** with unique seeds and bump storage - **Signer validation**: `authority: Signer<'info>` - **Account constraints**: `has_one = authority` for authorization - **Checked arithmetic**: `checked_add` to prevent overflow - **Custom error codes**: `ErrorCode::Overflow` - **Events**: `#[event]` macro for on-chain events - **Overflow protection**: `overflow-checks = true` in `Cargo.toml` release profile **How to Audit & Deploy**: ```bash # 1. Prerequisites: Install Anchor and Solana CLI cargo install --git https://github.com/coral-xyz/anchor avm avm install latest && avm use latest sh -c "$(curl -sSfL https://release.anza.xyz/stable/install)" # 2. Set up wallet and switch to devnet solana-keygen new # if you don't have a keypair solana config set --url devnet solana airdrop 2 # request devnet SOL # 3. Build cd {baseDir}/examples/solana anchor build # 4. Update program ID (important for first deploy!) # Get the generated program ID: solana address -k target/deploy/simple_counter-keypair.json # Update declare_id!() in programs/simple_counter/src/lib.rs # Update [programs.devnet] in Anchor.toml anchor build # rebuild with correct program ID # 5. Run automated audit python3 {baseDir}/scripts/audit_solana.py --path {baseDir}/examples/solana # 6. Deploy to devnet (dry run first) python3 {baseDir}/scripts/deploy_helper.py \ --chain solana \ --path {baseDir}/examples/solana \ --network devnet \ --dry-run # 7. Actual deployment anchor deploy --provider.cluster devnet # 8. Post-deploy: Verify on Solana Explorer # https://explorer.solana.com/?cluster=devnet ``` --- ### Choosing the Right Example | Feature | Solidity (SimpleStorage) | Sui Move (SimpleCounter) | Solana (SimpleCounter) | |---|---|---|---| | **Language** | Solidity 0.8.20 | Move (2024.beta) | Rust + Anchor 0.30.1 | | **Build Tool** | Foundry (forge) | sui CLI | Anchor | | **Complexity** | Simplest | Medium | Most complex | | **Best For** | EVM chain beginners | Sui ecosystem learners | Solana/Anchor learners | | **Default Testnet** | Sepolia | Sui Testnet | Devnet | | **Testnet Tokens** | [Sepolia Faucet](https://cloud.google.com/application/web3/faucet/ethereum/sepolia) | `sui client faucet` | `solana airdrop 2` | ### Workflow for Any Example The workflow for all examples follows the same pattern: 1. **Install tools** → Check with `python3 {baseDir}/scripts/audit_<chain>.py --check-tools` 2. **Build** → Compile the project to ensure no errors 3. **Audit** → Run the automated audit script + AI deep review 4. **Fix** → Address any Critical/High findings before deployment 5. **Dry-run deploy** → Generate and preview the deployment command 6. **Deploy to testnet** → Execute the deployment on a test network 7. **Verify** → Check the deployed contract on the block explorer
