An OpenClaw skill for autonomous token swaps on Base via Aerodrome, powered by Gnosis Safe + Zodiac Roles.
This skill enables AI agents to perform secure, permissioned token swaps through a Gnosis Safe. The agent operates through Zodiac Roles module which restricts operations to:
- Swapping tokens via Aerodrome Router
- Approving tokens only for the Aerodrome Router
- All swapped tokens return to the Safe (no external transfers)
The human owner retains full control of the Safe while the agent can only execute swaps.

cd clawlett/scripts
npm install- Initialize the wallet (deploys Safe + Roles):
node clawlett/scripts/initialize.js --owner <YOUR_WALLET_ADDRESS>-
Fund the agent address with ~0.001 ETH for gas (address shown in output)
-
Run the script again - it will complete the setup automatically
-
Fund your Safe with tokens to trade
# ETH balance
node clawlett/scripts/balance.js
# Specific token
node clawlett/scripts/balance.js --token USDC
# All verified tokens
node clawlett/scripts/balance.js --all# Get quote
node clawlett/scripts/swap.js --from ETH --to USDC --amount 0.1
# Execute swap
node clawlett/scripts/swap.js --from ETH --to USDC --amount 0.1 --execute
# Swap by address (for tokens not in verified list)
node clawlett/scripts/swap.js --from USDC --to 0xa1832f7f4e534ae557f9b5ab76de54b1873e498b --amount 100 --executeAll scripts support --rpc flag for custom RPC endpoints:
node clawlett/scripts/balance.js --rpc https://base.llamarpc.com
node clawlett/scripts/swap.js --from ETH --to USDC --amount 0.1 --rpc https://base.llamarpc.comProtected tokens can only resolve to verified addresses (scam protection):

This skill is designed to work with OpenClaw agents. The agent can:
- Check wallet balances on request
- Get swap quotes and explain trade details
- Execute swaps after user confirmation
- Protect users from scam tokens
