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.","timeline":[{"date":"2021-04-01","event":"Tropykus launches on Rootstock (RSK) testnet.","source":"RootstockLabs Blog","source_url":"https://www.rootstocklabs.com/blog/tropykus-finance-defi-en-bitcoin-con-impacto-social/"},{"date":"2021-05-01","event":"Tropykus mainnet deployment on Rootstock goes live, supporting RBTC, DOC, RIF, and USDT markets.","source":"Rootstock Blog","source_url":"https://rootstock.io/blog/becoming-a-bitcoiner-in-the-defi-world/"},{"date":"2023-05-24","event":"Tropykus deploys experimental version on Polygon zkEVM, integrating API3 self-funded dAPIs for price oracles.","source":"API3 Medium / Cointelegraph ES","source_url":"https://medium.com/api3/tropykus-to-launch-on-polygon-zkevm-using-api3s-data-feeds-710fdc29b1c8"},{"date":"2023-06-14","event":"Tropykus RSK suffers a $150,000 exploit targeting the rBTC micro-market via a redeem rounding error and exchange rate manipulation.
