Steps to Convert OP to MNT
- Click Trade OP → MNT to open app.torque.fi with sell=OP and buy=MNT pre-filled.
- Confirm you have enough unified balance in the OP and MNT product buckets for the trade.
- Adjust slippage if needed (URL param slippage or Trade settings). Large same-chain sells over $10,000 may use tighter slippage.
- Review the quote — platform fee, slippage, and estimated output — then confirm. Torque routes from your unified balance automatically.
- Track one portfolio balance in Torque. Perps positions and PnL appear on trade and perps surfaces; drill into composition only if you want bucket detail.
