Clawlett

Secure token swaps and Trenches trading on Base Mainnet, powered by Safe + Zodiac Roles.

Swap engine: CoW Protocol (MEV-protected batch auctions). Token creation & bonding curve trading: Trenches (via AgentKeyFactoryV3).

Network: Base Mainnet (Chain ID: 8453)

Overview

This skill enables autonomous token swaps and Trenches token creation/trading through a Gnosis Safe. The agent operates through Zodiac Roles which restricts operations to:

• Swapping tokens via CoW Protocol (MEV-protected)
• Creating tokens on Trenches bonding curves
• Buying and selling tokens on Trenches bonding curves
• Approving tokens for CoW Vault Relayer
• Presigning CoW orders via ZodiacHelpers delegatecall
• Wrapping ETH to WETH and unwrapping WETH to ETH via ZodiacHelpers
• Sending swapped tokens only back to the Safe (no draining)

Capabilities

Agent Name (CNS)

Each agent can optionally register a unique name via the Clawlett Name Service (CNS). This name is the agent's app-wide identifier — no two agents can share the same name. The name is minted as an NFT on Base.

Pass --name during initialization to register a CNS name. If omitted, CNS registration is skipped. Once registered, it cannot be changed.

Token Safety

Verified Tokens

Protected tokens can ONLY resolve to verified Base Mainnet addresses:

If a scam token impersonates these symbols, the agent will detect and warn.

Unverified Token Search

Tokens not in the verified list are searched via DexScreener (Base pairs). Search results include:

• Contract address (on-chain verified)
• 24h trading volume and liquidity
• DEX where the token trades

Agent behavior for unverified tokens:

• Always display the warning with contract address, volume, and liquidity
• Ask the user to confirm before proceeding with the swap
• Never silently swap an unverified token

Setup

1. Owner provides their wallet address (and optionally an agent name)
2. Agent generates keypair → Owner sends 0.001 ETH on Base Mainnet to agent for gas
3. Agent deploys Safe on Base Mainnet (owner as sole owner)
4. Agent registers with backend and optionally mints CNS name on-chain (if --name provided)
5. Agent deploys Zodiac Roles with swap permissions
6. Agent removes itself as Safe owner (keeps Roles access)
7. Owner funds Safe on Base Mainnet with tokens to trade

Usage

Initialize

Initialize my wallet with owner 0x123...
Initialize my wallet with owner 0x123... and name MYAGENT

Check Balance

What's my balance?
How much USDC do I have?

Swap Tokens

Swap 0.1 ETH for USDC
Swap 100 USDC for ETH
Exchange 50 DAI to AERO

CoW Protocol swaps are MEV-protected. ETH is automatically wrapped to WETH when needed (CoW requires ERC20s). Wrapping is bundled into the swap transaction.

Wrap/Unwrap ETH

Wrap 0.5 ETH to WETH
Unwrap 0.5 WETH to ETH

Wrapping and unwrapping is done via ZodiacHelpers delegatecall. When swapping from ETH via CoW, wrapping is handled automatically as part of the swap transaction.

Trenches Trading

Trenches enables token creation and bonding curve trading on Base. Tokens are created via the AgentKeyFactoryV3 contract and traded on Uniswap V3-style bonding curves.

All on-chain operations go through ZodiacHelpers wrapper functions (createViaFactory, tradeViaFactory) which validate the factory address and forward calls with explicit ethValue (since msg.value doesn't work in delegatecall).

Create a token called "My Token" with symbol MTK
Create a token paired with BID (default base token)
Create a token with anti-bot disabled and an initial buy
Buy 0.01 ETH worth of MTK on Trenches
Sell all my MTK tokens
What's trending on Trenches?
Show me the top gainers
Get info on MTK token

IMPORTANT — Token creation parameter collection: When a user asks to create a token, the agent MUST collect ALL of the following parameters before executing. If the user's request is missing any of these, ask them to provide the missing values. Do NOT use defaults silently — always confirm each parameter with the user.

The agent should present the user with a summary of all parameters (including defaults) and ask for confirmation before executing the creation.

Token creation defaults:

• Base token: BID (use --base-token ETH for ETH pairing)
• Anti-bot protection: ON (10-minute sniper protection window)
• Initial buy is blocked when anti-bot is enabled (agent can't buy during protection window)
• Use --no-antibot to disable protection and allow initial buy
• Use --image to attach a custom token image (PNG/JPEG/WEBP, max 4MB)

Image upload flow:

• Images are uploaded to /api/skill/image before token creation
• The returned imageUrl is passed to the token creation API
• If image upload fails, the token creation will fail (image is required)

Anti-bot protection and buying:

• The agent cannot buy any token that has anti-bot protection currently active (within the 10-minute window after creation)
• This applies to all tokens, not just ones the agent created
• Both the client and backend enforce this — the backend will refuse to issue a swap signature for protected tokens
• Wait for the protection window to expire before buying

The agent will:

1. Upload token image via /api/skill/image (returns imageUrl)
2. Get creation signature from /api/skill/token/create (includes imageUrl)
3. Display token details for confirmation
4. Execute via Safe + Roles (ZodiacHelpers delegatecall)
5. After creation, share the token page URL: https://trenches.bid/tokens/[address]

The agent will:

1. Resolve token symbols (with scam protection)
2. Get quote from CoW Protocol
3. Display swap details for confirmation:
   • Token symbols (e.g., ETH → USDC)
   • Token addresses (verified Base Mainnet contracts)
   • Input amount (what you're selling)
   • Output amount (estimated amount you'll receive)
   • Fee breakdown
   • ETH wrap amount (if applicable)
4. Ask for explicit user confirmation
5. Execute via Safe + Roles

Configuration

Scripts read from config/wallet.json (configured for Base Mainnet):

{
  "chainId": 8453,
  "owner": "0x...",
  "agent": "0x...",
  "safe": "0x...",
  "roles": "0x...",
  "roleKey": "0x...",
  "name": "MYAGENT",
  "cnsTokenId": 1
}

Updating

When the user says "update to latest", follow this procedure:

1. git fetch --tags origin in the clawlett repo
2. Read current version from scripts/package.json
3. Identify the latest git tag (e.g., git tag -l --sort=-v:refname | head -1)
4. Read MIGRATION_GUIDE.md for the migration path between current and latest version
5. Show the user: current version, new version, summary of changes, and whether on-chain steps are required
6. ASK the user: "Do you want to proceed with this update?" — do NOT proceed without explicit confirmation
7. If confirmed: git checkout <tag>, then walk through each migration step with the user

Some updates are code-only (just checkout the new tag). Others require on-chain transactions signed by the Safe owner (e.g., updating Roles permissions for a new ZodiacHelpers contract). The migration guide specifies which.

Security Model

1. Safe holds all funds - Agent wallet only has gas
2. Zodiac Roles restricts operations:
   • Can only interact with ZodiacHelpers
   • ZodiacHelpers scoped with allowTarget (Send + DelegateCall)
   • Can only approve tokens for CoW Vault Relayer
3. No transfer/withdraw - Agent cannot move funds out
4. Scam protection - Common tokens resolve to verified addresses only
5. MEV protection - CoW Protocol batches orders, preventing sandwich attacks and other MEV extraction
