How scoring works →Summary
Zapper was a DeFi portfolio tracking and interaction platform founded in 2019 that reached 2 million monthly active users and raised approximately $16.5 million from investors including Mark Cuban and Framework Ventures. The platform announced it would permanently shut down all services on August 3, 2026, following a sustained decline in market demand and a damaging April 2025 domain hijacking incident in which attackers socially engineered Zapper's domain registrar to redirect users to a phishing page. The shutdown creates immediate user-protection concerns: lingering wallet permissions granted to Zapper's contracts should be revoked, and the closure creates conditions favorable for scammers to launch fake 'Zapper migration' or 'fund recovery' phishing campaigns targeting former users.
