- Mishandled exceptions and call stack limits
- Unsafe external calls
- Integer overflow/underflow
- Number rounding errors
- Reentrancy and cross-function vulnerabilities

- Access control
- Centralization of power
- Business logic contradicting the specification
- Code clones, functionality duplication
- Gas usage
- Arbitrary token minting.
Quantstamp: “We have reviewed the code, documentation, and test suite and found several issues of various severities. Overall, we consider the code well-written and with sufficient documentation and a good test suite. We have outlined suggestions to follow best practices better, and recommend addressing all the findings to tighten the contracts for future deployments or contract updates.”
