NFT2NFT — Payment NFT(EV) for NFT (EV), Payment ERC20 for EV (NFT)- Polygon Network

This guide will take you through the third test towards the goal of the NFT2NFT marketplace release

Circuits of Value (COVAL)’s project EmblemVault https://emblem.finance is one step closer to its Universal Cryptocurrency/NFT Marketplace.

First thing to do, is to create an EmblemVault (EV) NFT

Ill be purchasing this EV from the last tests, on account 0x5B3cFb86a9575a2C42fd88AA71F0957004fa9209

Making an offer to trade this EV containing a xDai Nifty.ink NFT from this account 0x5fD31ec5b8bEdDF0312ae0905B74E50ab0DcDDa4

I have changed the settings to switch off Dark Mode — top left corner, easier to read the drop down button text.

Settings

Clicking the “Make an Offer (NFT2NFT)” button, then select “Emblem Vault V2” for the EV, then “825758” in the drop down, finally clicking “Make Offer” and sign the MetaMask transaction.

If you haven't used this before, there will be a further “Approve Spend” option to confirm on MetaMask

This will take the payment in Coval (set at 10 for this test) then display the offered EV/NFT.

You have the option to “Withdraw Offer” if you wish to cancel the transaction.

I have changed EVM account to the Owner of the NFT (0x5B3cFb86a9575a2C42fd88AA71F0957004fa9209)

Click the “My Offers (NFT2NFT)” will allow you to “Reject Offer” or “Accept Offer”, opening up MetaMask to sign the confirmation and swap will occur.
