4.2 Smart Contracts: Automated Implementation of Core Functions

DragonFly's smart contract is the core of platform automation, covering multiple key functional modules to ensure transparent, efficient and human-free operation. The following is the detailed design of each module: Staking Mining Contract Users participate in the mining activities of the DragonFly platform by staking TRC20 tokens (such as USDT or TRX). The smart contract records the staking time and amount, and automatically calculates and distributes the income at a rate of 0.2% every day (can be redeemed at any time, and automatically invested in the principal if not redeemed, such as 1000 USDT on the first day to earn 2 USDT, and 1002 USDT on the second day), and the principal can be redeemed at any time. Lending Contract The lending contract of the DragonFly platform allows users to pledge BTC or ETH. The smart contract evaluates the value of the pledged assets based on real-time market prices. Users can lend 70% of their value (in the form of USDT or TRX) and pay 1% interest per day. If the price of the pledged assets falls to the sum of the loan principal plus the accumulated interest, the contract will automatically liquidate and sell the pledged assets to repay the debt. Users can also return the principal and interest to redeem the assets at any time. This mechanism ensures price transparency through on-chain oracles and provides liquidity support for the platform with efficient automated processes, while balancing lending income and risk management. Revenue Distribution Contract When a private placement project in which the platform participates is listed on a secondary market (such as Binance or Uniswap) and generates income, the smart contract will distribute the income in proportion to the number of DGFY held by the user. These income may be issued in the form of TRX, USDT or project tokens. The distribution process is fully automated and recorded on the blockchain, which users can verify at any time through transaction hashes to ensure fairness and traceability. Governance Contract DragonFly introduces the DAO (decentralized autonomous organization) governance model. Users holding DGFY can initiate proposals (such as adjusting the mining reward ratio, introducing new features) and vote through smart contracts. The contract has a built-in voting weight mechanism. The more DGFY a user holds, the greater the voting influence. After the proposal is passed, the contract will automatically execute relevant adjustments to improve community participation and platform transparency.
