In Liminal Vaults, you can add your exchange accounts, such as Binance accounts. You can manage digital assets across multiple exchanges, including easy transfers and real-time balance monitoring. You can add both main as well as sub accounts in Vaults. Main accounts are the default account on the exchange. Deposits and withdrawals take place from this account. Sub accounts are used to securely store large funds and to segregate different teams, accounts. Sub accounts aren’t used to make direct transfers (deposits or withdrawals). You can link sub accounts to main accounts. Once connected, you can transfer funds to the sub account from the main account. Transfers between main accounts and sub-accounts are off-chain and do not require a network fee. The movement between sub-accounts is not supported.
