VERDICT

Should I use Zapper?

Not disclosed - zapper.xyz

Skip. Zapper, the Mark Cuban-backed DeFi portfolio dashboard, announced permanent closure in 2025 after seven years — there is no product left to buy. Anyone wanting live DeFi tracking should choose an active alternative like De.Fi or CoinStats instead.

Confidence

Medium. Based on ~14 public sources; many 'Zapper' search results describe unrelated products (bug zappers, a South African payments app), so only zapper.xyz-relevant items were used.
