How to pay for the course?

Send the payment in USDT to the LETIT wallet address. There are 3 networks to choose from:

TRC-20 USDT (Tron): TPd11uJT49Y1T5qouyPbHvFZNYDacjwFR5

BEP-20 USDT (BNB Chain): 0xf9A4f9Ab9497d3Fb88ECF271807173D79A0055a8

ERC-20 USDT (Ethereum): 0xf9A4f9Ab9497d3Fb88ECF271807173D79A0055a8

After payment, a unique hash of the transaction will be shown. You need to send it to our support t.me/letit_support and press the button "I paid" at the bottom of the page.

Unfortunately, without this information we will not be able to accept the order..

Your hash is proof of payment.
To verify that the money was sent to the wallet listed above, you can upload your hash to one of the sites:
https://tronscan.org/#/
https://bscscan.com/
https://etherscan.io/
The hash is in your transaction history (sometimes referred to as TXid)
