anchored·x4PpwY…hLqJSummary
Slope Wallet (Slope Finance) was a Solana-based mobile cryptocurrency wallet that suffered a catastrophic security breach on August 2, 2022, in which over 9,200 wallets were drained of approximately $4–8 million in assets due to the app transmitting users' unencrypted seed phrases to a third-party telemetry service (Sentry). The root cause was a severe security misconfiguration by Slope Finance, in which the mobile application logged plaintext private key material without proper scrubbing. No formal victim compensation was established, the team declined to publicly accept responsibility, and founder Leal Cheung subsequently launched a new project (zkME) without resolution for affected users.
