Furucombo

Furucombo operates as a transaction batching protocol within the decentralized finance ecosystem, allowing users to bundle multiple DeFi actions into a single on‑chain transaction. The service is designed to simplify complex interactions such as lending, swapping, and yield farming by reducing gas costs and improving user experience. The project is headquartered in Taiwan.

On February 27, 2021, Furucombo suffered an exploit in which an attacker deployed a fraudulent contract impersonating Aave v2, tricking the protocol into granting unauthorized access. This "evil contract" hack resulted in the theft of over fourteen million dollars worth of cryptocurrency, with the stolen funds subsequently routed to a privacy mixer. The incident prompted the team to disable the vulnerable components and advise users to revoke any problematic token approvals as a precaution.

Furucombo’s distinguishing attribute lies in its focus on transaction batching as a means to enhance composability and efficiency across various DeFi protocols. The protocol’s design emphasizes minimizing user steps while maintaining security through smart contract interactions. Following the 2021 breach, the project’s response highlighted its capability to quickly isolate affected contracts and communicate mitigation steps to its community.
