Mango Markets

A Solana cross-margin trading protocol offering spot, perps, and lending under one collateral account — known for the 2022 oracle-manipulation exploit.

Mango pioneered cross-margin trading on Solana: one collateral pool backs spot positions, perps, and borrows all at once, with per-asset risk parameters. In October 2022, Avraham Eisenberg exploited a price-oracle manipulation to drain ~$117M; he was later convicted of fraud.

Mango v4 launched after the exploit with redesigned oracles, a hardened risk engine, and new MNGO governance. It remains an important reference design for cross-margin DeFi.
