Crypto taxes are complicated. Your tools shouldn't make them harder.

Most investors are leaving money on the table — selling the wrong lots, missing harvesting windows, or discovering tax surprises after it's too late to act. LotLens gives you the visibility to make smarter decisions all year, not just at tax time.

Lot-level tracking

Track every purchase as a separate lot with its own cost basis, acquisition date, and current gain/loss — not just an average.

Tax-loss harvesting

Instantly see which lots are underwater, what you'd save by selling them, and how losses offset your realized gains.

HIFO, FIFO & Specific ID

Compare cost-basis methods before you commit to a sale — so you can choose the one that costs you least.

Cost basis follows your coins

Move crypto to a hardware wallet and your cost basis comes with it. LotLens preserves your original purchase price across every wallet.

Built by an investor, for investors

I built LotLens because I was tired of doing this in spreadsheets. It's free during early access — I'd love your feedback.
