Too many users have stacks of `$BTC` or stablecoins such as `$USDC` lying in their wallets gathering dust. DeOrderBook has an elegant solution to help ensure users keep accumulating wealth even while they keep their most beloved currencies close. Using a revolutionary protocol design that takes oracles out of the equation, DeOrderBook is able to offers users real yield and maximum capital flexibility in a uniquely secure environment of decentralization.\
\
The DeOrderBook solution revolves around the four core token types that make up its ecosystem, each with their own important associated actions.

* [HODL](/hodl/explaining-hodl.md): To enter the DeOrderBook ecosystem, users must first mint HODL tokens from supported cryptocurrencies. HODL tokens can then be used as collateral to back [DeOrders](/deorders/explaining-a-deorder.md), which are essentially limit orders.
* [$DOB](/usddob/explaining-usddob.md): The native governance token of the platform, earned at a continuous rate as placed DeOrders mature. `$DOB` can be [locked back](/usddob/locking-usddob.md) onto the platform for rewards in the form of revenue-sharing and BULLET tokens.
* [SNIPER](/sniper-and-bullet/explaining-sniper-and-bullet.md#what-are-sniper-tokens): An option writer obligation token, generated in tandem with BULLET tokens when placing a [DeOrder](/deorders/explaining-a-deorder.md). Can be combined with matching BULLETs to unwind orders at any time before expiry date.
* [BULLET](/sniper-and-bullet/explaining-sniper-and-bullet.md#what-are-bullet-tokens): An option right token, generated in tandem with SNIPER tokens. These are awarded to eligible [$DOB lockers](/usddob/locking-usddob.md), and have the unique property of being able to exercise DeOrders. Tradable at the [BULLET Bazaar](/sniper-and-bullet/bullet-bazaar.md).
