☠️ 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.
