# Welcome

:hand\_splayed:Hello Sentizens, <https://hub.sentre.io>

## Sentre in the first look

The first time of learning about Sen, you may be a bit confused amount Sentre, SenHub, and SenSwap. By the below explanation, we hope that we can make it clear to you:

* **Sentre** refers to the whole ecosystem, including everything such as SenSwap, SenHub, etc.
* **SenHub** is a platform that offers a base for blockchain developers to quickly build and ship decentralized applications (DApps) to users.

## Individual development is hard

If you are an individual developer and you're incubating an innovative idea, there are several things you need to do before success. [UniSwap](https://uniswap.org/) needed 2 years to bring their idea to people. [Compound](https://compound.finance/) had a talented team but also spent more than a year to launch the product.

{% hint style="danger" %}
:hourglass\_flowing\_sand: You have to spend a lot of unexpected time to realize your ideas.
{% endhint %}

After a long time of struggling with code on your local machine, you - an individual developer - need to rent servers, buy domains, subscribe to many third services just for an official launch. That may consume a lot of money.

{% hint style="danger" %}
:money\_with\_wings: You have to spend money on expensive services.
{% endhint %}

Furthermore, you have to do some marketing stuff that's even beyond the endurance of a geek. It's obvious that the process is very challenging and likely failed.

{% hint style="danger" %}
:exploding\_head: You have to do many things that aren't your strength.
{% endhint %}

In the end, the final evil is liquidity. If you build a DeFi protocol, liquidity is essential to run your protocol. Your idea may be never known by the public because of a lack of liquidity.

{% hint style="danger" %}
:droplet: Liquidity is a very limited resource for a new protocol.
{% endhint %}

## Sentre leverages innovative ideas

Thus, Sentre aims to solve a solution to help developers tackle these challenges and encourage innovation. A developer can:

* [x] Quickly develop a DApp by several provided libraries by SenOS.
* [x] Be a native application in Sentre.
* [x] Instantly approach a large number of users.
* [x] Inherit liquidity from primary services in Sentre.
* [x] Not to pay for Sen services.
