DefiLPKit

You put tokens into a crypto exchange pool to earn fees, prices move, and the deposit ends up worth less than the same tokens left doing nothing in a wallet. The pool's share of trading fees has to make up for that, and network fees (gas) on every transaction take another cut. DefiLPKit works out all three before any money goes in, and it runs without a wallet connection.

You paste a pool address or pick a token pair and set a price range. The calculator then puts the expected fees next to the expected loss and the gas cost. The range matters because pools on Uniswap v3 and similar exchanges pay a provider fees only while the price stays inside the bounds that provider chose.

A Range Coach suggests a width for the pair, and Range Studio replays that range against past hourly prices to show how often it would have stayed inside. Each figure shows its source and the time it was read. The site marks model results as estimates and says they are not a promised return.

Pasting a wallet address reads existing positions from public data, with nothing to sign or approve, and range alerts check saved bounds once an hour. A separate check handles pools of tokenized US stocks and tests what a price jump at the stock market open would do to a position. Some pools have limited history, so their fee rate can be missing.
