Tropykus RSK
Summary
Tropykus is a DeFi lending and borrowing protocol deployed on the Rootstock (RSK) Bitcoin sidechain, founded in 2021 by a Colombian team targeting Latin American underbanked communities. On June 14, 2023, the protocol suffered an exploit in its rBTC micro-market due to a redeem rounding error and exchange rate manipulation, resulting in losses of approximately $150,000 — roughly 10% of total value locked at the time. The team committed to full reimbursement of affected users and subsequently reverted to Compound Finance's original codebase, but the incident highlighted unresolved smart contract risks in a customized fork.
