anchored·3EfQTt…hXc3Summary
Platypus Finance is an Avalanche-based stablecoin automated market maker (AMM) and issuer of the USP stablecoin that suffered three separate exploits in 2023, losing a combined total of approximately $11.75 million. The first and most severe attack in February 2023 exploited a logic flaw in the protocol's emergency withdrawal function, draining roughly $8.5–9.1 million and causing the USP stablecoin to lose its dollar peg. Two French brothers identified by blockchain investigator ZachXBT were arrested and later acquitted on criminal charges after one argued he was an 'ethical hacker'; as of 2024 the protocol's total value locked had collapsed from over $200 million at peak to below $100,000.
