DApp - Desktop Flex Application.
DApp login and pincode - credentials, made up by Trader, pincode is used to encrypt DApp keys in the device’s storage (where desktop application is running).
DApp authorization - process of passing DApp’s hash of pincode, login and Dapp public key to Surf via QR code and receiving Trader’s user_id (it is calculated in Surf and placed on blockchain in a special User Index contract).
DApp user_id - value that DApp receives in the end of authorization process. DApp will use it later to create orders and to search for Trader’s wallets. Identifies Trader’s device.
```
user_id = hash(surf_private_key, hash(DApp_pincode, DApp_login)).  
```
DApp pubkey update - temporary pubkey that is generated in DApp’s background for the user upon DApp installation, so it changes with each re-install, and when it is removed from application storage (by cleaning cache or after its lifetime has ended). Meanwhile user_id stays constant, provided that user uses the same login+pincode. Every time the dapp is installed Authorization is performed and if user_id already exists and pubkey was changed - Flex Debot updates pubkey in all wallets with lent tokens for this Trader.
Gas - native EVER tokens on the balance of Flex smart contracts used to cover various that need to be paid in order for Flex exchange and Flex user accounts to function.
Order - request for sell or buy, created by user. Orders can be in one of the following states: not executed, partially executed, fully executed.
DeBot - a simple hat-based interface for interacing with smart contracts. DeBots data and logic is stored in smart contracts on-chain which makes them decentralized.
DeBot browser - an app that can access DeBots and render the chat-based DeBot interface. Currently Ever Surf is used at the defaulr DeBot browser for Flex.
Flex Auth DeBot - The DeBot which facilitates Flex authorization via a chat-based interface.
TIP3 tokens - Everscale standard for distributed token architecture. This standard is used both for tokens inside Flex and for most non-native tokens wrapped for Everscale. Currently TIP3.2 tokens are used.

Flex API Glossary

Super Root - a contract that is used for Flex migrations. Stores information the Flex Contract System migrations and some additional statuses that reflect the exchange state.
Flex Contract System - a set of contracts that altogether work as a decentralized exchange. Consists of 3 groups of contracts: Wallet (manages token wrappers and wallets), Exchange (manages pairs and orders) and User (supports user authorization and user funds management).
Global Config - contract that stores all the data related to 1 Flex exchange migration ( wallet, exchange and user groups versions).
Flex API - service that provide read access to Flex data.

Trader Data Glossary

Flex Client - Contract that helps manage funds on Flex. Flex Client can delegate (lend) some of her money to Traders who can trade on Flex from DApp.
Trader - Entity that trades on Flex. Represented by UserID contract, deployed by Flex Client.
