Smart contract risk focuses on the technical security of a currency based on its underlying code. If one of the supported currencies is compromised, collaterals will be affected, threatening the solvency of the protocol. Projects must have undergone audits to be considered, yet smart contract risk is significant, bug bounties can help but it cannot be fully mitigated. We assess maturity based on the number of days and the number of transactions of the smart contract as a representation of use, community and development. These proxies show how battle-tested the code is.
