• You have some NFTs that are really, really valuable. You don’t want to lose these NFTs, even if the rest of your account is compromised, including your owner key.
• Today, you might put your NFTs in a separate EOA and lock the private key in a bank vault.
  • But then you can’t use the NFTs to get into exclusive events!
• The Cold Storage plugin will let you secure your NFTs just as hard, but as part of your main modular account!

1. Installing the Cold Storage Plugin
   • The owner specifies a highly secure storage key when installing the plugin
2. Locking an NFT
   • The owner can lock NFTs (all ERC721s, collections, or tokens) and place them in cold storage
3. Transferring NFT as the Owner
   • Transferring a locked NFT is blocked
   • Transferring a NFT that isn’t locked is fine
4. Transferring a Locked NFT with Storage Key
   • The storage key has permission to transfer locked NFTs

1. The storage key also has permissions to unlock NFTs and change the storage key
2. Uninstalling the Plugin
   • The plugin blocks uninstalls when there locked NFTs

• git clone [email protected]:OMGWINNING/cold-storage-plugin.git
• cd cold-storage-plugin
• yarn install
• yarn run dev to load the site at http://localhost:3000
