How do I calculate my Optimism (OP) cost basis and unrealized profit?

Divide your total USD paid by the total OP tokens owned to find your average cost per OP. Multiply your OP holdings by the live OP market price and subtract your total amount paid to see your exact unrealized gain or loss.

Does PaperclipGo track or store my Optimism (OP) holdings?

No. All Optimism (OP) portfolio calculations run 100% locally in your browser using client-side localStorage. Your token balances and buy prices are never transmitted to any server.

Why Scenario Modeling Matters for Optimism (OP)

Within the digital asset market, Optimism (OP) operates as a Superchain Layer-2 Ecosystem known as a OP Stack rollup framework powering an interconnected Superchain of Ethereum Layer-2 networks. Because OP experiences distinct volatility cycles compared to traditional equities, static portfolio trackers only tell half the story. By modeling both downside drawdown thresholds and upside target multiples in advance, OP holders can define clear cost-basis breakeven points and avoid emotional decisions during high-volatility sessions.

Transparent Math: How Your OP Numbers Are Calculated

1. Average Cost per OP  = Total USD Paid ÷ Total OP Owned
2. Current OP Value     = Total OP Owned × Live OP Price (via anonymous proxy)
3. Unrealized Gain / Loss  = Current OP Value − Total USD Paid
4. Return Percentage (ROI) = ((Current OP Value − Total USD Paid) ÷ Total USD Paid) × 100
5. Scenario Value (Δ%)     = Current OP Value × (1 + (Scenario Slider % ÷ 100))
