# Overview

### What are Strategies? <a href="#how-strategies-work" id="how-strategies-work"></a>

A Strategy (or *vault*) is a smart contract that runs a specific yield routine on top of another DeFi protocol. AlphaFi runs vaults on top of:

* **CLMM DEXs** — Cetus, Bluefin, Momentum (liquidity vaults)
* **Lending protocols** — Navi, Bucket, AlphaLend, and more
* **Liquid staking tokens** — stSUI, vSUI vaults
* **Stablecoins** — USDC, USDT, USDY vaults

Each vault has one job: take your deposit, earn yield from one specific source, and grow your position over time.

### How it works?

Every vault runs the same five steps on a loop:

1. **Deposit** — You add an asset. The vault gives you a *receipt token* representing your share.
2. **Deploy** — The strategy puts your deposit into the underlying protocol.
3. **Accrue** — The position earns yield: trading fees, lending interest, or reward tokens.
4. **Auto compound** — Several times a day, the strategy claims rewards, swaps them into the vault's asset, and reinvests.
5. **Rebalance** (CLMM vaults only) — If price drifts out of range, the strategy resets the position around the new price.

When you withdraw, your receipt token is burned and you get your share back — principal plus all the compounded yield, minus the performance fee on the yield.

### Core Actions

There are only three things you'll ever do:

* **Deposit** — Add funds. Use one token (the vault zaps it for you) or both tokens of a pair.
* **Withdraw** — Pull funds out. No lockup on any standard vault.

### Position as Receipt Token

When you deposit, the vault mints a receipt token to your wallet. It's your proof of deposit and your share of the vault.

You don't have to do anything with it. The AlphaFi interface reads it automatically. But if you send the receipt token to another wallet, your position moves with it.

### Key Features

**Automated Yield Aggregation.** AlphaFi sits on top of Sui's top protocols and routes your capital to the best yields.

**Auto-Compounding.** Rewards are harvested and reinvested several times a day. The APY shown already includes this.

**Auto-Rebalancing (CLMM Vaults).** Concentrated liquidity positions only earn when price is in range. AlphaFi's CLMM vaults rebalance automatically when price moves out.

**Single-Sided Deposits (Zap).** Most LP vaults need both assets of a pair. AlphaFi vaults let you deposit just one — the contract handles the swap.

**Non-Custodial & Trustless.** AlphaFi never holds your funds. Audited onchain contracts does the work. Withdraw anytime, no permission needed.
