Is there any difference in delivery using CreateWithSeed than without it? If so, how could I measure this improvement? Congratulations on the content!

I've created an Associated Token Account for a seed account (by setting allowOwnerOffCurve to true when creating the ATA), but now if I want to close it, I need the signature of the seed account. Is it possible to get the signature / keypair of the seed account?

Is it possible to use publickey string as the SEED? I believe no, since SEED can be maximum of 32 characters, whereas publickey length is 44. Please help guide how to do so, maybe needs to trim the publickey to 32 length? Then how to ensure its still unique? i.e. const SEED = new Keypair().publicKey.toBuffer(); const newAccount = await PublicKey.createWithSeed(funder.publicKey, SEED, SystemProgram.programId) Thank you in advance

Interesting question! What's the usecase?

@jimchan3409 4 месяца назад

@@Solandy Lets say I'm building a nft minting/transfer platform for a game. Candymachine cannot be used because NFT cannot be pre-defined. Therefore, Durable Nonces Txn is selected, where each nonce account is derived from user's wallet address via PublicKey.createWithSeed. This is the case because if the whole platform is using the same nonce account, there might be a chance when multiple users are sending the transaction with nonceAdvance, some might failed since nonce will already changed. To prevent this, maybe each user will have their own nonce account, where it can be derived from SEED so that theres no need to store in the DB that this user got this nonce account. I rather derived the nonce account with user wallet address and use it.

@@Solandy In short, I need to create a nonce account for each of my users on the platform. I want to derive from admin wallet address, with user wallet address, so that I don't need to store in DB, I can derive it anytime.
