## Wallet and top-up

The balance is topped up in USDT via TRC20 or BEP20. Each user gets a personal deposit address,
so incoming funds are attributed automatically.

## Premium and payouts

Premium is charged from the internal balance and is reflected in the subscription status
immediately. Payouts are created as separate requests tracked in the financial history.

## Referral links

Several personal links can be created for different acquisition channels, and codes can be
validated publicly before registration. The structure supports three levels: L1, L2 and L3.
