# Callput Lite Trader

Trade Callput spreads on Base. MCP builds unsigned_tx; Bankr signs and broadcasts.

## Integration Pattern (Bankr)

1. callput_execute_spread -> unsigned_tx + usdc_approval
2. If usdc_approval.sufficient == false -> sign + broadcast approve_tx first
3. POST /agent/sign(unsigned_tx) -> signed_tx
4. POST /agent/submit(signed_tx) -> tx_hash
5. callput_get_request_key_from_tx(tx_hash) -> request_key
6. Persist request_key -> poll callput_check_request_status

## Hard Rules

1. Spread-only. No single-leg execution.
2. Always callput_portfolio_summary before new position.
3. MCP never holds CALLPUT_PRIVATE_KEY.
4. Save every request_key from get_request_key_from_tx.
5. High IV (>80% ETH, >70% BTC) favors sell spreads.
