Hello, we are an existing NFT project that was minted as OpenSea1155, we need to do a burn swap to 721 to reach our new goals.
The NFT holder is to pay the gas. We have the UI ready for our website and a sample smart contract that another project used to do same swap.
In conclusion we need a contract that sends the existing 1155 to a burn wallet and sending the new 721 version back to the holder.
There are 3006 NFTs in the collection on Ethereum
