How to make an auction with the new metaplex js sdk? - solana

Question

I am working on building a solana marketplace and trying to update from the old solana marketplace to auction house.
code:
const authority = metaplex.identity();
const auctionHouse = await metaplex
.auctions()
.createAuctionHouse({
sellerFeeBasisPoints: 200,
requiresSignOff: false,
treasuryMint: WRAPPED_SOL_MINT,
authority: authority.publicKey,
canChangeSalePrice: true,
feeWithdrawalDestination: publicKey,
treasuryWithdrawalDestinationOwner: publicKey,
})
.run();
const listNft = async () => {
try {
const NFTs = await metaplex.nfts().findAllByOwner(publicKey).run();
console.log(NFTs[4].mintAddress.toString(), " nft");
const auctionHouse = await metaplex
.auctions()
.findAuctionHouseByCreatorAndMint(publicKey, WRAPPED_SOL_MINT)
.run();
const listtx = metaplex
.auctions()
.builders()
.createListing({
mintAccount: NFTs[4].mintAddress,
price: lamports(1 * LAMPORTS_PER_SOL),
auctionHouse: auctionHouse,
});
var rpcClient = await metaplex.rpc().sendTransaction(listtx);
console.log(rpcClient, "listed nft");
} catch (error) {
console.log(error);
}
};
const getListing = async () => {
const NFTs = await metaplex.nfts().findAllByOwner(publicKey).run();
const retrievedAuctionHouse = await metaplex
.auctions()
.findAuctionHouseByCreatorAndMint(publicKey, WRAPPED_SOL_MINT)
.run();
console.log(retrievedAuctionHouse?.address?.toString(), "auction pubkey");
const retrieveListing = await metaplex
.auctions()
.for(retrievedAuctionHouse)
.findListingByAddress(NFTs[4].mintAddress)
.run();
console.log(retrieveListing, "retrieving listings");
};
const bidNft = async () => {
const NFTs = await metaplex.nfts().findAllByOwner(publicKey).run();
const auctionHouse = await metaplex
.auctions()
.findAuctionHouseByCreatorAndMint(publicKey, WRAPPED_SOL_MINT)
.run();
const { bid, buyerTradeState } = await metaplex
.auctions()
.for(auctionHouse)
.bid({
mintAccount: NFTs[5].mintAddress,
price: lamports(0.5 * LAMPORTS_PER_SOL),
});
console.log(bid, buyerTradeState, "bidding");
};
errors:

Answer 1

Found a way around
Instead of using metaplex.auction().builder().createListing i used metaplex.auctions().for(auctionHouse).list().
Then funded the auction fee payer account which is a pda.
Finally in findListingByAddress i passed the sellerTradeState
const { listing, sellerTradeState } = await metaplex
.auctions()
.for(auctionHouse)
.list({
mintAccount: NFTs[1].mintAddress,
price: sol(1.5),
})
.run();
For fetching the listed nft
const retrieveListing = await metaplex
.auctions()
.for(retrievedAuctionHouse)
.findListingByAddress(
sellerTradeState
)
.run();

Answer 2

Just from the information provided above, there are two issues:
You might have run the createAuctionHouse instruction already once which created the Auction house and now that you are running the listNft function which also runs createAuctionHouse instruction, it throws an Account already exists error. You can see why this happens here: https://stackoverflow.com/a/72808405/19264629
You are using the NFTs mint address in findListingByAddress instruction, which is wrong. You have to create a ListingReceipt as stated here: https://docs.metaplex.com/guides/auction-house/#auction-house-receipts while creating the listing itself (this needs to be done in one single transaction). Once this is done, you need to plugin the receipt address in the findListingByAddress to fetch the listings.

Got it to work. The trick was to fund the auction house "Fee Account" as explained above and in Auction House CLI: I cannot execute the sale instruction to list my NFT
const ah = await mx
.auctionHouse()
.findByAddress({ address:ahKey })
.run();
const nft = await mx
.nfts()
.create({
name:"TESTNFT",
symbol: "TESTNFT",
uri: "https://blah.com",
sellerFeeBasisPoints : 100,
creators: [
{
address: wallet.publicKey,
share: 100,
}]
})
.run();
const price = sol(0.1);
const { listing, sellerTradeState } = await mx
.auctionHouse()
.list({
auctionHouse: ah,
mintAccount: nft.mintAddress,
price
})
.run()
