Hey, I was wonder if you had any code examples of a smart contract creating a Take Order and then matching two orders.

Kuldeep | Multiplier.Finance#3336:

+1(to the reply above)

@eugene Nacu | Rarible If a Contract wants to buy an NFT for a fixed price, it will call the matchOrders() method only of the ExchangeV2 contract but how do we get all the params needed?

Is this even likely to be done using a SC?

izkp#1401:

up i can help. let me find some code snippets

you can use the rarible api endpoints to help prepare the transaction

before submitting to exchangev2 contract

joelcodes#4467:

Yeah I imagine we would have to hit some rarible endpoints to grab the signature for the make order. Which means we might not be able to do this on chain fully

izkp#1401:

right it's a mashup of api calls and contract calls

here's a starter app which shows how to do that from an EOA

https://github.com/austintgriffith/scaffold-eth/tree/rarible-starter-app

but to confirm, you want to interact via a contract? i also have that, but less polished

there's some good info in here
