The Lingo platform is a decentralized application (dApp) that caters to three types of users. Users with non-custodial wallets can buy and sell $LINGO tokens, participate in monthly airdrops, book hotels, and manage their accounts. Users without non-custodial wallets can still access the platform, buy and sell $LINGO with a credit card, book hotels, and manage their accounts, with Lingo acting as an intermediary. The Lingo administrator operates the smart contracts, manages funds for real estate purchases, and conducts monthly airdrops to token holders.

1. LINGO PLATFORM FEATURES LIST

At a high level, the Lingo platform serves as a decentralized application (dApp) catering to three distinct types of users.

1. Users connecting with a non-custodial wallet (e.g., MetaMask) can gain full access to the Lingo platform and the following functionalities:
   • Users can claim the airdropped $LINGO tokens either from the dApp interface or directly from the smart contract.
   • Optional account management functionalities include updating personal information such as name, phone number, email, and address.
   • Users can access metrics showing their token holdings, the expected $LINGO airdrop, and the history of their actions, travels, and rewards accumulated.
   • They can directly buy and sell $LINGO tokens within the website using their preferred wallet, thanks to the integration with a Decentralized Exchange (e.g., Uniswap).
   • To participate in the monthly $LINGO airdrop, users have the option to lock and unlock their $LINGO. The airdrop represents the monthly rent generated by Lingo's real estate and the Company’s purchases. They’re $LINGO tokens bought back with fiat currency obtained from the rental yield.
   • Additionally, users can use their $LINGO tokens to book hotels through the platform. However, due to regulatory requirements, users are required to provide certain mandatory information such as name, phone number, and email.
2. Users connecting with the user/password method (without a non-custodial wallet) can still access the Lingo platform and the following functionalities:

   • Booking hotel accommodations using $LINGO directly from the Lingo platform is facilitated.

   • To ensure account security and provide recovery options, users must create an account with a username and password, along with providing an associated email address. They can also also update account information, such as their name, phone number, and address.

   • Metrics are provided to all users, offering insights about their token holdings, the expected $LINGO Airdrop, and the history of rewards claimed and other actions.

   • The platform displays the airdropped $LINGO tokens monthly, eliminating the need for users with managed wallets to manually claim them. Lingo manages this process and abstracts it for the users.

   • Users have the capability to withdraw $LINGO to an external wallet, such as a Ledger device, a non-custodial wallet, or a centralized exchange

   • The Lingo platform manages the $LINGO tokens on behalf of these users, acting as an intermediary between them and the underlying smart contract. Direct interaction with the contract is not possible.

   • Users can lock and unlock their $LINGO tokens in Rent Eligibility

   • Users can purchase $LINGO tokens using a credit card (CB), with Lingo acting as the intermediary for the transaction.

   • Selling $LINGO tokens and withdrawing the funds to a configured bank account via wire transfer is supported.

3. The Lingo administrator has specific privileges and responsibilities within the platform:
   • The administrator possesses the authority to operate the smart contracts, enabling the transfer of funds between treasury accounts for the purpose of purchasing new real estate.
   • Additionally, the administrator is responsible for airdropping the $LINGO tokens to holders every month.

1.1 USER EXPERIENCE OVERVIEW

The Lingo platform offers several benefits to its users. Users with non-custodial wallets can conveniently buy and sell $LINGO tokens directly within the platform using their preferred wallet, thanks to the integration with a Decentralized Exchange. By locking their $LINGO tokens, these users become eligible for the monthly airdrop, which represents the rent generated by Lingo's real estate. Additionally, they can utilize their $LINGO tokens to book hotels through the platform, providing a practical use case beyond trading. Transparent metrics are also provided, allowing users to track their token holdings, expected airdrops, and action history.

Users without non-custodial wallets also benefit from the platform. They can easily access Lingo using a user/password login method without the need for a separate wallet. These users can purchase $LINGO tokens directly with a credit card, as Lingo acts as an intermediary. Lingo also manages their tokens, simplifying the process and eliminating the need for direct interaction with smart contracts. They can conveniently book hotels using $LINGO tokens and have control over their account details, such as personal information updates.

In summary, the benefits of the Lingo platform include convenient token trading, airdrop eligibility, a practical token utility for hotel bookings, transparent metrics for monitoring, simplified access and token acquisition, hassle-free token management, seamless hotel bookings, and easy account control.

2. HIGH-LEVEL ARCHITECTURE

In addition to its innovative features, Lingo harnesses the power of smart contracts and blockchain technology to create a highly secure and transparent ecosystem. Smart contracts, powered by blockchain, play a central role in facilitating various functionalities within the platform.

Lingo's smart contracts autonomously execute predefined actions based on predetermined conditions. These contracts are deployed on a blockchain network, ensuring immutability, transparency, and tamper-resistant execution of transactions and processes.

By utilizing smart contracts, Lingo enables users to buy and sell $LINGO tokens securely and directly within the platform. Users with non-custodial wallets can leverage the integration with a Decentralized Exchange to perform token transactions in a decentralized manner, eliminating the need for intermediaries and ensuring the integrity of the trading process.

Moreover, the monthly airdrop of $LINGO tokens to eligible holders is also governed by smart contracts. These contracts automatically distribute the airdropped tokens based on predefined rules, providing a fair and transparent process.

This automated distribution mechanism, powered by blockchain technology, ensures users receive airdropped tokens without manual intervention, enhancing efficiency and trust within the ecosystem.
