# Auto-Match
Auto-Match, in a nutshell, searches for existing orders that meet or exceed initial order criteria, then auto-fills the matches prior to creating the initial order.
When executing the order, your order will be created with any remaining tokens after the Auto-Matching took place.
## Example
Two orders already exist on OTSea. These orders are open and unfilled. The orders are:
Order A: Selling 1000 $OTSEA for .01 ETH
Order B: Selling 2000 $OTSEA for .03 ETH
**Blockto A then wants to buy 100 $OTSEA tokens for .1 ETH**, so they head to the order creation page to input the order. During the process, the system locates the two orders that are already open and are at a better price than their order. Assuming Blockto A confirms the Auto-Match of both orders, the order creation process will look like the following:
Order initiated, offering .1 ETH for 100 $OTSEA \[0.001 ETH per token]
**Auto-Match #1:** Buy 1000 $OTSEA for .01 ETH from **Order A** \[0.00001 ETH per token]
**Auto-Match #2:** Buy 2000 $OTSEA for .03 ETH from **Order B** \[0.000015 ETH per token]
**Create Order With Remainder:** Sell .06 ETH for 60 $OTSEA
The result here is that Blockto A received many more tokens than they were initially seeking, since the system identified orders at a better price that they were not aware of.
Auto-Match operates as a hybrid order book, that fits into the existing order system of OTSea. Users can always choose whether to create orders with or without Auto-Matched orders, though the frontend will always present the user with Auto-Match orders that are at an equal or better price than they requested.
Auto-Match is available on all chains.
