Unsung hero saves DeFi protocol from potential exploit: Finance Redefined

Welcome to Finance Redefined, your weekly dose of essential decentralized finance (DeFi) insights — a newsletter crafted to bring you significant developments over the last week.

The last week’s headline was dominated by some of the biggest hacks in DeFi. This week is redemption time for many DeFi protocols that either averted an attempted hack or got a significant chunk of their stolen funds back.

The BitBTC bridge reportedly had a bug that would essentially allow an attacker to mint fake tokens on one side of the bridge and swap them for real ones. However, one Twitter user was able to foresee the vulnerability and informed the cross-bridge platform about it.

The Moola Market attacker has scored about a half-million dollar “bug bounty” after choosing to return a majority of the cryptocurrency they exploited from the Celo-based lending protocol. Cryptocurrency market maker Wintermute repaid a $92 million TrueFi loan on time despite suffering a $160 million hack.


Mango Market hackers that returned a significant chunk of the $117 million stolen from the protocol could still face legal action despite the protocol deciding to award him a $50 million bounty.

The top 100 DeFi tokens remained bearish for another week, as the majority of the tokens traded in red, barring a few. The total value locked also remained below $50 billion for the second consecutive week.

Twitter user saves cross-chain bridge from potential exploit

A cross-chain bridge between BitBTC and the Ethereum layer-2 network Optimism has been able to avoid a potentially costly exploit thanks to the work of an eagle-eyed Twitter user.

The custom cross-chain bridge offers a ramp for users to send assets between Optimism’s network and BitAnt’s DeFi ecosystem, which includes yield services, nonfungible tokens (NFTs), swaps and the BitBTC token, in which 1 million BitBTC represents 1 Bitcoin (BTC).

MangoMarket’ss exploiter said actions were ‘legal,’ but were they?

The $117 million Mango Markets exploiter has defended his actions as “legal,” but a lawyer suggests that they could still face the consequences.

Self-described digital art dealer Avraham Eisenberg outed himself as the exploiter in a series of tweets on Oct. 15, claiming he and a team undertook a “highly profitable trading strategy” and that it was “legal open market actions, using the protocol as designed.”
