Summary

Pando Rings is an algorithmic lending and borrowing protocol built on the Mixin Network by Fox One, modeled on Compound Finance. On November 5, 2022, an attacker exploited a price oracle vulnerability tied to the sBTC-WBTC LP token on 4swap to drain approximately $21.9 million in ETH, BTC, and EOS from the protocol; an additional ~$50 million remained frozen in the attacker's wallets. The protocol subsequently suffered further losses in the September 2023 Mixin Network infrastructure breach, and as of late 2023 remained in a limited operational state with interest accrual and liquidations suspended.
