V3 or V4 - Which version should I use?

PreviousOrderbook API

Last updated 3 years ago

Currently there are two versions of the NFT Swap SDK: and .

Which version?

tl;dr:

By default, we recommend using V4. It's the future of the 0x protocol and is hyper gas-optimized (currently the cheapest way to buy/sell NFTs on Ethereum).

One exception: V4 currently does not support buying and selling bundles. If you require bundle support in the short term, you will need to use V3. Eventually V4 plans to be able to support bundles, but for now use V3.
