# Overview

**Sendit** is a permissionless DeFi protocol on Solana offering three main products:

1. Borrow**: Isolated money markets to borrow against any SPL tokens**
2. Trading**: Margin Trading for any SPL token**
3. Earn**: SOL Yielding + Memecoin Yielding**

***

### Isolated Money Markets

Sendit implements classic **overcollateralized lending**, similar to Aave, Save Finance, or Kamino — but with **isolated risk per token**.

* Borrowers deposit SPL tokens as collateral and borrow SOL.
* Lenders supply SOL and earn a dynamic **Supply APR** from borrower interest, loan issuance fees, and reward incentives.
* Each token has its own independent SOL pool, eliminating cross-market contagion.

### Margin Trading

Sendit's native margin trading is built directly on top of the lending layer:

* Traders borrow SOL to take up to **3x long positions** on any supported SPL token.
* Trades are executed via **Jupiter**, with pricing from **Pyth** or **Switchboard** oracles.
* Liquidations are transparently handled through real liquidity, not synthetic markets.

### SOL Earn Vaults

Users can deposit SOL into one of three actively managed yield vaults:

* **Blue Chip**, **Mid Cap**, or **Small Cap**\
  These vaults dynamically allocate SOL across markets to maximize yield while adhering to different risk profiles. Yield is auto-compounded and sourced from protocol-native incentives.

### Memecoin Yielding Vaults

Deposit your memecoin as collateral → borrow SOL → re-lend the SOL → earn and auto-compound yield — all automated.\
These vaults are **high-yield, high-risk**, and ideal for holders of volatile tokens looking to maximize capital efficiency.
