Bringing Bitcoin to DeFi

Bringing Bitcoin to DeFi

DeFi is blockchain’s first killer app, with assets locked up approaching $1 billion USD. But one major asset is missing: Bitcoin. Bitcoin is not only the first crypto asset, but the largest - with over $168 billion USD of Bitcoin in circulation it has deep pools of liquidity. It is one of the least volatile cryptocurrencies and has a large network of fiat on and off ramps. All these properties make it a great crypto-collateral. We think Bitcoin has the potential to transform the DeFi landscape as the most widespread and liquid asset available today.

DeFi’s Double-Edged Sword

DeFi’s Double-Edged Sword

However this composability also introduces more risk. These issues have existed for a while, but have been made easier to exploit through the introduction of flash loans. While flash loans themselves do not introduce new vulnerabilities, they level the playing field for attacks which previously required large amounts of capital.
