Create hot wallets
Hot wallets are wallets where your keys are accessible online. Hot wallets are wallets that are operated via APIs and hence can be automated. In Liminal, these wallets are created and managed via APIs. Once created, you can access hot wallets through the Liminal Vaults user interface to view the total wallet balance, individual asset balances, configured policies, etc. These wallets are of two types—deposit and withdrawal wallets. All hot wallets use the Multi-Party Computation (MPC) technology.
Take the following steps to create your hot deposit and withdrawal wallets.
