How do you ensure the security of each wallet?
Please check this information from WP about security:
3.1. All network services have an independent/distributed connection to each other (personal area, API, databases, etc.).
3.2. A cold wallet with a transaction confirmation from several participants (multisig) is used for token distribution.
3.3. A smart contract has the function of suspending transactions in the event of unpredictable situations so we can protect the participants' funds and transfer them to a more secure smart contract.
3.4. We do not store private keys from the participants' wallets, which increases the security and keeps the personal accounts of the participants.
3.5. The security of the collected funds during the ICO will be provided by a multi-signature on the wallets. The withdrawal of funds from these wallets will be possible if there are 2 or more signatures of team members. It will be publicly available to view data balances of these wallets.
3.6. Cold storage of a part of the collected funds to finance the project will be organized on the basis of hardware wallets (KeepKey/Ledger). It will be created a backup copy on physical media (flash drives) for each hardware wallet and their backup copies. Hardware wallets and their backup copies will be stored separately: one part in the safe of one bank, the other part in the banking cell of another bank in another country.
