HOW THE AUTOPSY WORKS.
Where the data comes from
Every number is rebuilt from public Ethereum activity indexed by OpenSea: the sales, mints and transfers that touched the address you pasted. Nothing is read from your wallet, because your wallet is never connected.
Trades that never touched OpenSea's index — some Blur volume and private sales — are not counted. A wallet that traded mostly elsewhere will look quieter here than it really was.
Made & lost
Each sale is paired against the purchase that funded it, oldest lot first (FIFO), per token. A pairing only counts when both sides settled in ETH or WETH.
Made is the sum of every winning trade. Lost is the magnitude of every losing trade. They are reported separately on purpose: a single net figure lets a good year hide a bad one. Net is simply made minus lost.
Gas and marketplace fees are not attributed, so realised P&L is gross. Your true net is slightly worse than what you see here.
What is never invented
An NFT that arrived by mint, airdrop or plain transfer has no purchase price on chain, so it never receives an invented zero cost basis. Selling it still records the proceeds, but the trade carries no P&L and is excluded from made, lost and win rate.
Sales settled in a currency we cannot convert without guessing a historical rate are skipped rather than estimated. Unavailable is always better than invented.
Fumbled
Fumbled is hypothetical missed upside, not a financial loss. For every NFT the wallet sold, it compares the sale price against what the same collection's floor would pay today.
This is a present-day comparison, clearly labelled as estimated. It is not a claim about the historical peak, and only ETH-denominated floors are used.
Flipping, mints & win rate
A flip is a trade opened and closed within seven days; the figure shown is the realised P&L of those trades. Win rate is winning trades over all FIFO-matched trades. Mint take is the proceeds from NFTs this wallet minted and later sold — mint price and gas are not deducted, so it is a gross take, marked estimated.
NFT IQ
Deterministic, never random. It blends how much of the wallet's turnover ended up as profit with how often it was right, and pulls thin histories toward neutral rather than flattering or punishing them.
PROFITABILITY = 50 + 50 × NET ÷ (MADE + LOST)
Fewer than three closed trades? The score is averaged halfway back to 50.
Coverage
A run reads up to 1,000 recent Ethereum events and the current holdings, and every result states the event count and the earliest date it covers. If OpenSea rate-limits the request mid-run, the result says so instead of quietly returning less.
Privacy
Fumbled.lol reads public wallet activity. It does not connect a wallet, request a signature, or accept a seed phrase or private key. NFT metadata is rendered as plain text and images are only loaded over https — never executed as HTML or SVG.
