Risk Assessment
Watch Out
Protocol Code Quality
  • Code reviewed by several experienced auditors; BlockSec and PeckShield
  • Anonymous team reduces transparency
  • No documented protocol hacks since launch
Protocol Maturity
  • Latest protocol version launched in 2023; maturity over one year minimizes technical risk as smart contracts are well battle-tested
  • Top 20% by total value locked slightly reduces risk
  • Multisig wallet controls protocol upgrades
  • Multisig consists of less than 4 signers, which makes the protocol more susceptible to centralization risks
  • No timelock exists or no information documented, which mean a malicious actor could approve upgrades without any delay
  • Low voting power concentration reduces risk
Protocol Design
  • Robust controls to mitigate oracle price manipulation
  • Secured lending market that uses a combination of isolated and cross-collateral pools depending on the individual asset serves to reduce risk
  • Basic controls in place to prevent risky borrowing
  • Basic mechanisms in place to incentivize liquidations
  • No reserves or no stability module
