# Zap In

#### Deposit ANY asset into ANY pool.

A51 simplifies liquidity provision—no need for complex swaps or manual management. Zap is a simple and efficient way to deposit into liquidity pools using any asset you hold.

Imagine you have $DAI and want to add liquidity to the $ETH/$cbBTC pool—A51’s "Zap In" feature makes this process seamless.

Here’s how it works:

1. Head to the A51 dApp (pro.a51.finance) to get started.
2. Choose the liquidity pool you wish to invest in to. In this case, let’s pick the $ETH / $cbBTC pool.
3. Click "Zap In". This feature allows you to enter a pool without manually swapping your assets.
4. Specify how much $DAI you want to deposit, and click Deposit. A51 will handle the rest.

The dApp will automatically convert a portion of your $DAI into $ETH and another portion into $cbBTC, ensuring you provide balanced liquidity to the pool.

Currently, the Zap In feature is live on **Arbitrum** and **Base**, making it even more accessible for users on these networks.
