Audit log
Every state-changing event for Zapper: moderation decisions on community submissions, plus corrections and updates from the news pipeline. URL-based decisions are designed to carry three independent witnesses — the original source, an Internet Archive snapshot, and a Solana memo signed by our publicly-disclosed publisher key. Archive coverage is still being backfilled, so each decision below reports its own snapshot status rather than assuming one exists.

The platform was founded in 2019 and won Kyber Network's DeFi Hackathon in its inaugural year. It grew to serve over 2 million monthly active users at its peak and processed more than $13 billion in transaction volume over its lifespan. Co-founder and CEO Seb Audet described the platform's mission as building 'the homepage of DeFi' — an accessible entry point for retail users engaging with on-chain protocols. The platform operated for nearly seven years before announcing closure.","heading":"Platform Overview and History","severity":"low","sources":[{"credibility":2,"name":"Mark Cuban-Backed Zapper DeFi Shuts Down After 7 Years — CoinCentral","type":"news_article","url":"https://coincentral.com/mark-cuban-backed-zapper-defi-shuts-down-after-7-years-and-its-not-alone/"},{"credibility":2,"name":"Zapper CEO Announces Orderly Wind Down After 7-Years — Yahoo Finance","type":"news_article","url":"https://finance.yahoo.com/markets/crypto/articles/zapper-ceo-announces-orderly-wind-054302955.html"},{"credibility":2,"name":"DeFi Homepage Zapper Closes $15M Funding Round — Crypto Briefing","type":"news_article","url":"https://cryptobriefing.com/defi-homepage-zapper-closes-15m-funding-round/"}]},{"content":"Zapper raised approximately $16.5 million across multiple rounds. A seed round in early 2020 raised $1.5 million from Coinbase Ventures, CoinFund, and CoinGecko Ventures. In May 2021, Framework Ventures led a $15 million Series A that included participation from Mark Cuban, Sound Ventures (co-founded by Ashton Kutcher), Spartan Group, DeFiance Capital, ParaFi Capital, and Aave founder Stani Kulechov. The Series A funds were directed toward building a DeFi app store, launching a mobile application, and expanding the team. Despite the significant capital raised, the platform was unable to achieve a sustainable revenue model and ultimately wound down.","heading":"Funding and Investors","severity":"low","sources":[{"credibility":2,"name":"DeFi Homepage Zapper Closes $15M Funding Round — Crypto Briefing","type":"news_article","url":"https://cryptobriefing.com/defi-homepage-zapper-closes-15m-funding-round/"},{"credibility":1,"name":"Zapper.Fi — Mark Cuban Companies","type":"official","url":"https://markcubancompanies.com/companies/zapper-fi/"},{"credibility":2,"name":"Zapper DeFi Platform Calls It Quits After Seven-Year Run — Blockonomi","type":"news_article","url":"https://blockonomi.com/zapper-defi-platform-calls-it-quits-after-seven-year-run"}]},{"content":"On approximately April 1, 2025, attackers executed a social engineering attack against Netim, the registrar managing Zapper's .fi domain extension. The attack succeeded in hijacking control of the zapper.fi domain and redirecting visitors to a malicious phishing page. Zapper's official account on X (formerly Twitter) issued an urgent public warning: 'An attacker has socially engineered Netim, our .fi domain provider. DO NOT VISIT OR CLICK ANY LINKS ON THIS DOMAIN. zapper(.xyz) is the only way to access our website.' The platform temporarily migrated all traffic to zapper.xyz as its canonical domain while working to recover the .fi extension. The specific number of users exposed to the phishing page and any associated financial losses were not publicly disclosed by the company. Multiple reporting outlets noted that the platform 'struggled to recover' from this breach in terms of user trust, and it is cited as a contributing factor in the eventual decision to shut down.","heading":"April 2025 Domain Hijacking Incident","severity":"high","sources":[{"credibility":2,"name":"Zapper official X post on domain attack — @zapper_fi","type":"social_media","url":"https://x.com/zapper_fi/status/1907089451223781877"},{"credibility":2,"name":"Zapper subjected to social engineering attack — AiCoin","type":"news_article","url":"https://www.aicoin.com/en/news-flash/2295090"},{"credibility":2,"name":"The Zapper.fi domain has been hijacked — ChainCatcher","type":"news_article","url":"https://www.chaincatcher.com/en/article/2175147"},{"credibility":3,"name":"Zapper Advises Caution Following Domain Provider Attack — Binance Square","type":"news_article","url":"https://www.binance.com/en/square/post/22338475113017"},{"credibility":2,"name":"Mark Cuban-Backed Zapper DeFi Shuts Down After 7 Years — CoinCentral","type":"news_article","url":"https://coincentral.com/mark-cuban-backed-zapper-defi-shuts-down-after-7-years-and-its-not-alone/"}]},{"content":"CEO Seb Audet announced the platform's closure publicly on X in early July 2026. His statement read: 'After close to 7 years building Zapper, I regret to announce that Zapper will be winding down.' He added: 'We evaluated a number of different options, pursued some to the fullest extent possible, and came to the realization that an orderly wind down is the best course of action. At the end of the day, the market decides.' All services — including the zapper.xyz website, mobile applications, and API platform — ceased operations on August 3, 2026. Existing API customers received transition guidance by email.

These approvals, if granted to malicious or abandoned contract addresses, can be exploited to move tokens from a wallet without the owner's private key. Users who interacted with Zapper's swap, liquidity, or transaction features are advised to audit and revoke outstanding wallet approvals using tools such as Revoke.cash or Etherscan's token approval checker before or immediately after the August 3, 2026 closure. The platform itself stated that on-chain assets are not held by Zapper and are unaffected by the closure, but this statement does not address the risk posed by pre-existing on-chain approvals granted to third-party contracts surfaced through the Zapper interface.","heading":"User Protection: Wallet Permission Revocation","severity":"high","sources":[{"credibility":2,"name":"Zapper To Shut Down DeFi App After Nearly Seven Years — Crypto Adventure","type":"news_article","url":"https://cryptoadventure.com/zapper-to-shut-down-defi-app-after-nearly-seven-years/"},{"credibility":2,"name":"Approval Hacks and Exploits — Revoke.cash","type":"research","url":"https://revoke.cash/exploits"},{"credibility":2,"name":"How to Revoke Token Approvals and Protect Your Wallet in 2026 — DEXTools","type":"other","url":"https://www.dextools.io/tutorials/revoke-token-approvals-wallet-security-tutorial-2026"}]},{"content":"The shutdown of a well-known platform with 2 million former monthly active users creates conditions that are historically exploited by scammers. Common post-shutdown attack vectors include: fake 'Zapper migration' websites claiming to help users recover funds or transfer positions; phishing emails impersonating Zapper's team and directing users to connect wallets on fraudulent domains; and fraudulent social media accounts or Telegram groups posing as official Zapper support channels offering 'fund recovery' services. The April 2025 domain hijacking incident demonstrates that Zapper's brand and domain infrastructure have already been targeted by adversaries willing to conduct social engineering against registrars. Users should treat any unsolicited communication referencing Zapper after August 3, 2026 — whether by email, social media, or messaging app — as a likely phishing attempt. No legitimate fund recovery is possible for a non-custodial dashboard, as Zapper held no user funds.","heading":"Post-Shutdown Phishing and Impersonation Risk","severity":"critical","sources":[{"credibility":2,"name":"Zapper official X post on domain attack — @zapper_fi","type":"social_media","url":"https://x.com/zapper_fi/status/1907089451223781877"},{"credibility":2,"name":"DeFi Dashboard Zapper to Shut Down All Services on Aug. 3 — FinanceFeeds","type":"news_article","url":"https://financefeeds.com/defi-dashboard-zapper-to-shut-down-all-services-on-aug-3/"},{"credibility":3,"name":"What to Do When a DeFi Protocol Shuts Down — Coin98","type":"other","url":"https://coin98.com/blog/what-to-do-when-a-defi-protocol-shuts-down/"}]},{"content":"Zapper's closure coincides with a wave of DeFi and crypto infrastructure shutdowns in mid-2026.

Industry analysts note that while crypto venture capital funding increased 57.6% year-over-year to $4.21 billion in Q2 2026, deal volume contracted ninefold over ten quarters, with capital concentrating among fewer, larger projects and leaving mid-tier infrastructure products without a viable path to profitability.","heading":"Broader Industry Context","severity":"low","sources":[{"credibility":2,"name":"Mark Cuban-Backed Zapper DeFi Shuts Down After 7 Years — And It's Not Alone — CoinCentral","type":"news_article","url":"https://coincentral.com/mark-cuban-backed-zapper-defi-shuts-down-after-7-years-and-its-not-alone/"},{"credibility":2,"name":"Zapper Shutdown Shows DeFi's Revenue Problem — Coin360","type":"news_article","url":"https://coin360.com/news/zapper-shutdown-defi-dashboard"},{"credibility":2,"name":"DeFi Dashboard Zapper Announces Closure After Seven Years — Crypto Economy","type":"news_article","url":"https://crypto-economy.com/defi-dashboard-zapper-announces-closure-after-seven-years-of-on-chain-tracking/"}]}],"sources_used":[{"credibility":2,"name":"DeFi Dashboard Zapper to Shut Down After 7 Years — CoinTelegraph","type":"news_article","url":"https://cointelegraph.com/news/defi-dashboard-zapper-to-shut-down-after-seven-years"},{"credibility":2,"name":"Mark Cuban-Backed Zapper DeFi Shuts Down After 7 Years — CoinCentral","type":"news_article","url":"https://coincentral.com/mark-cuban-backed-zapper-defi-shuts-down-after-7-years-and-its-not-alone/"},{"credibility":2,"name":"Zapper CEO Announces Orderly Wind Down After 7-Years — Yahoo Finance","type":"news_article","url":"https://finance.yahoo.com/markets/crypto/articles/zapper-ceo-announces-orderly-wind-054302955.html"},{"credibility":2,"name":"DeFi Dashboard Zapper Is Shutting Down After Raising $15 Million — The Coin Republic","type":"news_article","url":"https://www.thecoinrepublic.com/2026/07/09/defi-dashboard-zapper-is-shutting-down-its-services-after-raising-15-million/"},{"credibility":2,"name":"DeFi Homepage Zapper Closes $15M Funding Round — Crypto Briefing","type":"news_article","url":"https://cryptobriefing.com/defi-homepage-zapper-closes-15m-funding-round/"},{"credibility":2,"name":"Zapper official X post on domain attack — @zapper_fi","type":"social_media","url":"https://x.com/zapper_fi/status/1907089451223781877"},{"credibility":2,"name":"The Zapper.fi domain has been hijacked — ChainCatcher","type":"news_article","url":"https://www.chaincatcher.com/en/article/2175147"},{"credibility":2,"name":"Zapper subjected to social engineering attack — AiCoin","type":"news_article","url":"https://www.aicoin.com/en/news-flash/2295090"},{"credibility":3,"name":"Zapper Advises Caution Following Domain Provider Attack — Binance Square","type":"news_article","url":"https://www.binance.com/en/square/post/22338475113017"},{"credibility":2,"name":"Zapper DeFi Platform Calls It Quits After Seven-Year Run — Blockonomi","type":"news_article","url":"https://blockonomi.com/zapper-defi-platform-calls-it-quits-after-seven-year-run"},{"credibility":2,"name":"Zapper CEO Reveals the Platform Will Wind Down — Crypto Economy","type":"news_article","url":"https://crypto-economy.com/zapper-ceo-reveals-the-platform-will-wind-down-after-exploring-every-viable-path-forward/"},{"credibility":2,"name":"Zapper Shutdown Shows DeFi's Revenue Problem — Coin360","type":"news_article","url":"https://coin360.com/news/zapper-shutdown-defi-dashboard"},{"credibility":2,"name":"DeFi Dashboard Zapper to Shut Down All Services on Aug. 3 — FinanceFeeds","type":"news_article","url":"https://financefeeds.com/defi-dashboard-zapper-to-shut-down-all-services-on-aug-3/"},{"credibility":2,"name":"Zapper To Shut Down DeFi App After Nearly Seven Years — Crypto Adventure","type":"news_article","url":"https://cryptoadventure.com/zapper-to-shut-down-defi-app-after-nearly-seven-years/"},{"credibility":2,"name":"DeFi Dashboard Zapper Announces Closure After Seven Years — Crypto Economy","type":"news_article","url":"https://crypto-economy.com/defi-dashboard-zapper-announces-closure-after-seven-years-of-on-chain-tracking/"},{"credibility":1,"name":"Zapper.Fi — Mark Cuban Companies","type":"official","url":"https://markcubancompanies.com/companies/zapper-fi/"},{"credibility":2,"name":"Approval Hacks and Exploits — Revoke.cash","type":"research","url":"https://revoke.cash/exploits"},{"credibility":2,"name":"Mark Cuban-backed DeFi dashboard Zapper shutters after 7 years — TradingView / CoinTelegraph","type":"news_article","url":"https://www.tradingview.com/news/cointelegraph:ee7ba4360094b:0-mark-cuban-backed-defi-dashboard-zapper-shutters-after-7-years/"}],"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.

How verification works. The “Row integrity” check above is computed in your browser — your machine recomputes the SHA-256 of the canonical bytes and compares against the stored hash. No avoid.net server can fake that check. The “full verify” link goes one level deeper: your browser fetches the on-chain transaction from a Solana RPC node and confirms the same hash is in the memo. If you don’t want to trust either avoid.net or the public RPC, run the CLI verifier on your own machine —
