As a smart contract security auditor, I see similar patterns in DeFi protocols. The key lesson here is that security audits should focus on:

  1. Access control patterns (tx.origin vs msg.sender vulnerabilities)
  2. Integer type choices (uint8 in loops causing permanent fund locks)
  3. Silent failures where functions don't revert but reduce output

I recently found Medium-High severity bugs in StellaSwap, Angle Protocol, and Stargate using exactly these patterns. The crypto wallet space needs more independent security researchers.
