Licensees should consider the use of multi-signature wallets (e.g., where multiple private keys are associated with a given public key and a subset of these private keys, sometimes held by different parties, are required to authorise transactions). Noting that there is no way to recover stolen or lost private keys unless a copy of that key has been made, multi-signature wallets may offer more security because a user can still gain access to its crypto-assets when two or more Private Keys remain available. (see also CRA-4.1.2 and CRA-4.1.3).
