modbender Batch Swap
Execute multiple token swaps in sequence with independent safety validation per swap.
Activation
Use this skill when the user says any of:
- "Swap X for Y and Z"
- "Rebalance to 50% ETH 50% USDC"
- "Buy 3 different tokens"
- "Execute these swaps: ..."
Input Extraction
| Parameter | Required | Default | Source |
|---|---|---|---|
swaps |
Yes | — | List of {tokenIn, tokenOut, amount} |
chain |
No | ethereum | Default chain for all swaps |
stopOnFailure |
No | true | Whether to halt on first failure |
Workflow
Parse all swaps from the user's message. Confirm token symbols resolve.
Pre-flight check: Verify total spending within daily limits and sufficient balance for all swaps using
check_safety_statusandget_agent_balance.Sequential execution: For each swap:
- Launch
Task(subagent_type:trade-executor)with swap parameters - Wait for confirmation before starting next swap
- Update running balance between swaps
- If
stopOnFailure=trueand swap fails, halt remaining swaps
- Launch
