Fortress Loans
Summary
Fortress Loans (fortress.loans) was an algorithmic money market and lending protocol on BNB Chain (Binance Smart Chain), launched in April 2021 by the JetFuel Finance team. On May 8, 2022, the protocol was drained of all funds — approximately $2.98 million — through a combined governance manipulation and oracle price manipulation attack. The protocol has been effectively inactive since, with DefiLlama recording a TVL of approximately $1,168 as of 2024, and the FTS governance token has lost effectively all of its value.
