Hot wallets are usually at a higher risk of being hacked, so we have established a list of hot wallets used in the system, including the identity of the owner of the private key. Hot wallets will be used to set up signatures for NFT purchase and sale orders.
There are 2 types of cold wallets:
For asset storage cold wallets, we will use 3-signature multisig wallets, transactions will be approved when 2 out of 3 signatures confirm.
For smart contracts that will be owned by their own cold wallet, this cold wallet has the ability to deploy a new smart contract, or update smart contract version or change contract information.
