5.1.3 Savings with Interest

Function Overview Users participate in the DragonFly platform's deposit and interest-bearing activities by depositing USDT or TRX, and receive daily dividend income, which is composed of the deposited currency and the platform token DGFY. The principal will be returned after the selected period ends. The following is the specific mechanism: Deposit and record: Users can only deposit USDT or TRX (other currencies are not supported yet), and the smart contract records the deposit amount, time and selected period (30 days, 90 days, 180 days or 365 days). Income is issued in the deposited currency, and an additional reward of equal value DGFY tokens. Income and dividends:

Daily dividends: Income is divided into two parts:

Fixed income: issued in the deposited currency, and the daily dividend ratio varies according to the period. DGFY rewards: issued in equal value, and the specific amount is dynamically calculated based on the DGFY market price on that day. Cycle and yield:

30 days: daily dividend 0.5% (deposited currency) + 0.1% equivalent to DGFY

90 days: daily dividend 0.6% (deposited currency) + 0.15% equivalent to DGFY

180 days: daily dividend 0.7% (deposited currency) + 0.2% equivalent to DGFY

365 days: daily dividend 0.8% (deposited currency) + 0.25% equivalent to DGFY Dividend distribution: Daily dividends are automatically distributed to user wallets, and users can withdraw or hold them at any time.

Principal return:

The principal is automatically returned to the user wallet after the selected cycle ends. For example, if you deposit 1000 USDT and choose a 30-day cycle, the principal of 1000 USDT will be returned on the 31st day. Early unlocking is not supported, and users need to choose a suitable cycle based on liquidity needs. Profit calculation and example:

User deposits 1000 USDT and selects a 30-day period:

Day 1: DGFY price is 0.5 USDT/coin

Fixed income: 1000 × 0.5% = 5 USDT DGFY reward: 1000 × 0.1% ÷ 0.5 = 2 DGFY Total dividend: 5 USDT + 2 DGFY Day 2: DGFY price rises to 1 USDT/coin

Fixed income: 1000 × 0.5% = 5 USDT DGFY reward: 1000 × 0.1% ÷ 1 = 1 DGFY Total dividend: 5 USDT + 1 DGFY Total income for 30 days (assuming DGFY price fluctuates): a total of approximately 150 USDT + 30-60 DGFY (the specific amount depends on the daily price). Return upon maturity: 1000 USDT principal will be returned on the 31st day. Flexibility and query:

Daily dividends can be withdrawn at any time, and the smart contract provides real-time income query function, and users can view the current accumulated income and DGFY reward status. The principal is locked until the end of the cycle to ensure the stability of funds.
