What are maker-taker order types and how do they represent buy and sell orders?
A maker order is an order that is placed on the order book and is not immediately matched with an existing order. A taker order is an order that is placed and is immediately matched with an existing order.
- Every NFT order that does not immediately transfer the NFT can be represented by a maker order. In the case of the SDK user making a sell-order, the
makerAssetis the NFT, and the
takerAssetis the ERC20 token in question. (e.g. WETH or USDC)
- This is the converse for an SDK user making an NFT buy-order. The
makerAssetis the ERC20 token, and the
takerAssetis the NFT.
Because Opensea and 0x and other marketplaces support a wide variety of ERC20 (for example, WETH or DAI) pairs to sell NFTs to, we've supported a generic maker-taker interface so users can have flexibility in choosing what denomination they buy in or sell to.
