Tracking what you hold across several wallets and chains is genuinely tedious, and Flip does it well: unified balances, transaction history, cost basis and realised and unrealised profit and loss in one place.
The valuation caveat
Valuing an NFT collection at floor price assumes you could sell every item at the floor, simultaneously, with no price impact. In an illiquid market that is never true — selling five items from a collection with three bids means hitting the bids and then waiting. Portfolio totals in this category should be read as an upper bound rather than a value.
Where it helps
Cost-basis tracking across chains is the most practically useful feature, particularly for anyone reconciling a year of activity for tax purposes. Multi-wallet aggregation removes the spreadsheet most active users otherwise maintain.
Coverage and cost
Major EVM chains with patchy support for smaller networks, a workable free tier and paid plans for power users.
Who should use it
Active NFT holders across several wallets who want cost-basis tracking, treating displayed portfolio values as indicative rather than realisable.
