☠️ Cause of death

User private keys were stored insecurely and exposed, letting attackers sweep funds directly out of self-custody-style wallets across many accounts.

📓 Lessons left behind

  • Never store users' private keys in plaintext or shared storage.
  • 'Non-custodial' tooling that holds keys is custodial in disguise.
  • Key exposure scales the loss to every user at once.

🌱 The idea that survived

Real self-custody

Underscored that trading tools must keep keys client-side and never expose them server-side.
