# LUXY Core

[LuxyCore](https://polygonscan.com/address/0x21C90bcE2943dD2B706248E906D4DF9637be27C4#code): 0x21C90bcE2943dD2B706248E906D4DF9637be27C4

### Match Orders

This is the core function of the Marketplace. Through this function the maker and taker orders are matched and executed in the following order:

1. Marketplace fee transfer
2. Royalty array transfer <mark style="color:green;">(Direct Royalty Payment)</mark>
3. Payout transfer (ERC-20, ERC-1155, Native Blockchain Token)
4. NFT payout transfer (ERC-721 )

The Payout transfer indication is due to the fact that any royalty or fee will be applied to those contracts only. Since ERC-721 is unique the protocol will never try to extract fees /royalties from the NFT payout. Given the scenario that an exchange between two different NFTs is made royalties or fees are not applied. Also, there is a priority order for the fee to be applied (it's only applied to one side of the transaction) which will go first to Native Blockchain Token, then to ERC-20, and finally to ERC-1155.
