Good day, I am currently writing a small program that mints an NFT using the Candy Machine ID. For this, I have https://github.com/metaplex-foundation/metaplex/blob/master/js/packages/cli/src/candy-machine-v2-cli.ts mint_one_token recoded in Go using your libraries. However, I always get as error:

Transaction simulation failed: Transaction loads a writable account that cannot be written.

Do you have any idea what this could be? Thank you very much!

Here is my code:

Hello, first of all, thanks for working on this. Very helpful in learning Solana/Metaplex as a Go dev. Kudos. Hoping to get some help on this, I'm trying to mint a new edition from an existing master edition to a new address and I'm hitting this error:

This is how I am doing it: payer is solana.privateKey of account that created and has the master edition withdrawalAddress is account to send the new edition to masterMint is the public key of the NFT

1. generated new keypair called newMintAccount
2. created token account: mint auth and freeze auth are payer.PublicKey(), mint account is newMintAccount.PublicKey()
3. created associated token account: wallet is withdrawalAddress, mint is newMintAccount
4. associatedTokenAddress is found via solana.FindAssociatedTokenAddress() using withdrawalAddress and newMintAccount.PublicKey()
5. MintTo instruction: amount 1, mint account is newMintAccount.PublicKey(), destination account is associatedTokenAddress and auth account is payer.PublicKey()
6. newMetadataKey is found via:

newMetadataKey, _, err := solana.FindProgramAddress(
		[][]byte{
			[]byte(token_metadata.PREFIX),
			solana.TokenMetadataProgramID.Bytes(),
			newMintAccount.PublicKey().Bytes(),
		},
		solana.TokenMetadataProgramID,
	)

7. newEditionPDA is found via:

newEditionPDA, _, err := solana.FindProgramAddress(
		[][]byte{
			[]byte(token_metadata.PREFIX),
			solana.TokenMetadataProgramID.Bytes(),
			newMintAccount.PublicKey().Bytes(),
			[]byte(token_metadata.EDITION),
		},
		solana.TokenMetadataProgramID,
	)

8. masterRecordMetadata is found via:

masterRecordMetadata, _, err := solana.FindProgramAddress(
	[][]byte{
		[]byte(token_metadata.PREFIX),
		solana.TokenMetadataProgramID.Bytes(),
		masterMint.Bytes(),
	},
	solana.TokenMetadataProgramID,
)

9. masterRecordEditionV2PDA is found via:

masterRecordEditionV2PDA, _, err := solana.FindProgramAddress(
	[][]byte{
		[]byte(token_metadata.PREFIX),
		solana.TokenMetadataProgramID.Bytes(),
		masterRecordMetadata.Bytes(),
		[]byte(token_metadata.EDITION),
	},
	solana.TokenMetadataProgramID,
)

10. editionPDA is found via:

edition := uint64(1)
x := math.Floor(float64(edition) / token_metadata.EDITION_MARKER_BIT_SIZE)
b := make([]byte, 8)
binary.LittleEndian.PutUint64(b, math.Float64bits(x))
editionPDA, _, err := solana.FindProgramAddress(
		[][]byte{
			[]byte(token_metadata.PREFIX),
			solana.TokenMetadataProgramID.Bytes(),
			masterRecordMetadata.Bytes(),
			[]byte(token_metadata.EDITION),
			b,
		},
		solana.TokenMetadataProgramID,
	)

11. tokenAccountOfMasterMint is found via:

tokenAccountOfMasterMint, _, err := solana.FindAssociatedTokenAddress(
	payer.PublicKey(),
	masterMint,
)

12. Finally, this is the instruction for minting a new edition:

printEditionInstruction := token_metadata.NewMintNewEditionFromMasterEditionViaTokenInstructionBuilder().
	SetArgs(token_metadata.MintNewEditionFromMasterEditionViaTokenArgs{Edition: edition}).
	SetNewMetadataKeyAccount(newMetadataKey). // pda from token_metadata.PREFIX, solana.TokenMetadataProgramID, newMintAccount.PublicKey()
	SetNewEditionPDAAccount(newEditionPDA).
	SetMasterRecordEditionV2Account(masterRecordEditionV2PDA).
	SetMintOfNewTokenAccount(newMintAccount.PublicKey()).
	SetEditionPDAAccount(editionPDA).
	SetMintAuthorityAccount(payer.PublicKey()).
	SetPayerAccount(payer.PublicKey()).
	SetOwnerOfTokenAccount(payer.PublicKey()).
	SetTokenAccount(tokenAccountOfMasterMint).
	SetUpdateAuthorityInfoAccount(payer.PublicKey()).
	SetMasterRecordMetadataAccount(masterRecordMetadata).
	SetTokenProgramAccount(solana.TokenProgramID).
	SetSystemProgramAccount(solana.SystemProgramID).
	SetRentInfoAccount(solana.SysVarRentPubkey)

As far as I can tell, this repo so far only supports decoding on-chain account data and instructions.

The Metaplex standard also describes how to store off-chain NFT data on the Internet (mostly on Arweave) https://docs.metaplex.com/nft-standard#uri-json-schema

It would be useful to add structs matching the off-chain data to this repo, and maybe a hardened HTTP client for fetching off-chain data from untrusted servers.

Sorry if I'm completely missing something here.

Trying to figure out how to set the primary_sale_happened flag on NFT metadata:

https://github.com/metaplex-foundation/metaplex-program-library/blob/master/token-metadata/program/src/state.rs#L227

Any help would be greatly appreciated! Gonna keep digging.

Getting

$ go get -u github.com/gagliardetto/metaplex-go/clients/token-metadata

got

github.com/gagliardetto/metaplex-go/clients/token-metadata imports
	github.com/gagliardetto/solana-go/text/format: cannot find module providing package github.com/gagliardetto/solana-go/text/format

Adds helper structs for dealing with off-chain NFT data.

I took the data from some random NFT, ran it through JSON-to-Go, and then cleaned it up a little and added missing attributes.

We might want to look into auto-generating these structs from a schema in the future.

Relates to #3

Hello! We hit an issue today during a mint, and realized we needed to set the collection ID during mint.

Here is an example transaction that was bot penaltied: https://explorer.solana.com/tx/2zP6tEw9vzGxGkPSDTyLKEzJieuP57LvzN8ddDbhm2cxaQR3PReqmA8pKLgYQYQP9sBbbABGFnZYqQuSMm6USjBV

You can see the error at the bottom of that tx:

Missing set collection during mint IX for Candy Machine with collection set, Candy Machine Botting is taxed at 10000000 lamports

In early March, it looks like Metaplex added a setCollection method: https://github.com/metaplex-foundation/metaplex/commit/58679aa432fed281cd4a7189123df397a5a266fe

Is there any chance you could add support for this?

Hey, after following the boilerplate code for minting from a candy machine, I get this error

https://github.com/metaplex-foundation/metaplex-program-library/discussions/178

This release on 02/01/2022 includes 4 new instructions:

• SetAndVerify
• FreezeDelegatedAccount
• ThawDelegatedAccount
• RemoveCreatorVerification

I'm wondering whether we can add support for these instructions? I can help out too

Thanks :)

When taking a look at the candy machine v2 go file in comparison to the metaplex rust/js program, what occurs with the remaining accounts variable use for such things as the whitelist or civic?

I'm working on a project where we have a server-side metaplex rust program(https://github.com/metaplex-foundation/metaplex/tree/release/v1.1.0) and I have deployed the nft-candy-machine and token-metadata on local separately and I have got two programid's, and from the client side metaplex-go (https://github.com/gagliardetto/metaplex-go) I have put my path of keygen(https://github.com/gagliardetto/metaplex-go/blob/87b7612310478a9669dbe22f31be10c9962da4c6/examples/candy/main.go#L27) and the programid's of nft-candy-machine(https://github.com/gagliardetto/metaplex-go/blob/87b7612310478a9669dbe22f31be10c9962da4c6/examples/candy/main.go#L77) and token-metadata(https://github.com/gagliardetto/metaplex-go/blob/87b7612310478a9669dbe22f31be10c9962da4c6/examples/candy/main.go#L80) along with the WalletFromPrivateKey(https://github.com/gagliardetto/metaplex-go/blob/87b7612310478a9669dbe22f31be10c9962da4c6/examples/candy/main.go#L569) with my wallet private key but im getting an error can you help on this.
