Implementation of EVAT
Technical Architecture and Foundational Choices
EVAT is built on the Solana blockchain, fully leveraging its high performance, low transaction costs, and robust development ecosystem. Each electric vehicle asset is minted as an NFT on-chain, with ownership, income rights, and dividend rights managed automatically by smart contracts. All key processes—fund flows, asset confirmation, dividends, and repayments—are executed transparently via on-chain contracts, with real-time data queries and automated settlements.
Capital Flow and Asset Operation Process
The entire on-chain and off-chain collaboration process revolves around three core participants: on-chain RWA investors, off-chain energy operators (Hinery), and installment riders.
Investors participate through the EnrgiX DeFi platform by depositing stablecoins such as USDT to subscribe to specific electric vehicle NFTs, thereby obtaining asset ownership. They may also choose to match with riders, leasing vehicles to them in exchange for dividend rights.
All funds are managed by smart contracts, which automatically allocate capital to vehicle procurement and installment financing. Within the ecosystem, the energy company Haitai Energy serves as the off-chain operator, responsible for vehicle procurement, deployment, management, and subsequent buyback.
Once installment riders receive their vehicles, they make scheduled repayments according to contract terms. Each repayment is instantly synchronized on-chain, with the system automatically distributing principal, interest, and project token dividends to NFT holders.
On-Chain and Off-Chain Data Integration
All rider activities—such as trip records, repayment progress, and device status—are synchronized in real time to the Solana blockchain. This not only ensures a high degree of transparency for asset and revenue flows, but also allows investors to continuously monitor asset performance and project fulfillment risk. The entire asset lifecycle operates without manual intervention, driven entirely by smart contracts.
Returns and Incentive Mechanisms
Investors in EVAT receive dual incentives: firstly, stable USDT interest returns from installment repayments; secondly, continual allocation of ENX governance tokens based on their holding and staking duration. For riders, daily usage also earns them points and project token rewards, reducing vehicle costs and encouraging consistent repayment.
