Zap In allows you to exchange (zap) your single token into LP in a single operation. This is convenient for users who want to take a position quickly.
How Zap In makes adding liquidity easy
Image you would like to add liquidity to VVS or MMF pool which requires you to have at least 2 tokens in your wallet. However, you only have one of them.
Normally, you would need to swap your existing token into underlying pool and then deposit those 2 assets into VVS or MMF pool. This works out to a total of 2 separate transactions. More transactions and more preparation to participate creates friction for the user and can make DeFi intimidating to get started.
Now everything becomes easier thanks to Zap In function, which allows you to deposit into VVS or MMF pool in a single transaction.
As you can see above, Zap In does all the work for you. It swaps half of your existing token for the other, deposits them into VVS/MMF pool, and then returns the VVS/MMF liquidity pool tokens to your address in a single transaction.
The result is you don't have to worry about having the specific tokens in exact prepared proportions before you can provide liquidity.
