Impossible to create ETH → NFT order with "buildOrder" method #77

Closed ErnestMironov closed 2 years ago

ErnestMironov commented 2 years ago

It is possible to create an NFT → ETH order, but it is impossible to create ETH → NFT.

A transaction ERC-20 → NFT fails with an error "cannot estimate gas", although a transaction ERC-20 (native token) → NFT passes successfully.

No, you cannot programmatically move ETH via contract like that unfortunately -- you can only use ETH as the taker.
