**❗️❗️Please note that after sending funds to the HASH7 balance, the transaction processing takes about two minutes, after which the funds will be automatically credited to your balance in the app. Transaction processing time may also depend on the load on the TON network.**

<mark style="color:red;">**Pay special attention to the network, since if the transfer is not made through the TON network, this will lead to an irrevocable loss of the asset.**</mark>
