A Guide to NFT Platform Security

  • Consensus Security: the difficulty of stealing assets by attacking the platform’s nodes/validators (e.g. through a 51% attack)
  • Bridge Security: the security of the mechanism for moving assets to and from Ethereum. This is usually the larger concern, as compromises generally put user funds directly at risk

Security Beyond Core Platforms

  • Wallet Security: how are user keys stored? What would be the impact if this storage system were compromised (e.g. a custodial wallet provider, a bad version of a native wallet app, a bad dependency in a browser extension)?
  • Metadata Security: how is asset metadata (including images) stored? If this metadata was altered or replaced due to a compromise, what would be the market impact?
  • Project Security: projects on any platform usually retain some admin keys for their project. What would happen if those keys were compromised? Does your project have active monitoring for breaches? Does your platform support best practices for key management?
  • Treasury Security: most platforms will have substantial reserves of their token (e.g. for use in rewards or grants). How are these funds held? How are transfers from the treasury authorized and executed? What would be the impact of a compromise?
  • Marketplace Security: how do marketplaces which support this protocol protect users from malicious transactions like copycat projects?
