On 30th November the DEX Uniswap made NFT trading available on its platform. Users will be able to trade digital collectibles across multiple marketplaces like OpenSea,x2y2,LooksRare, Sudoswap, Larva Labs, Foundation, NFT20, and NFTX. using the platform’s NFT aggregator tool. In addition, the platform says its new open-sourced Universal Router contract can save users up to 15% on gas fees compared to other NFT aggregators.

First way of saving ETH: more listings hence lower average floor prices

Being a NFT aggregator, it aggregates the listings of items for a collection from different marketplaces, which means that one should always expect to find the lowerest floor price for every collection and this let users save money

Second: thanks to a new custom smart contract, you can save gas fee

This is the real innovation: Uniswap devs created a new open-sourced smart contract called Universal Router (

) thanks to which users can swap ERC20 tokens and buy NFTs in a single transaction saving tens of thousands of gas units ( up to 15% Uniswap claims ) on gas costs

This kind of transaction are called “redeem” (involing an ERC20 token swap and then an NFT redeem) in our analysis while “sale” ones are the usual NFT sale transactions.
