I have minted 1000 items using sugar and candy machine in devnet, and everything is fine. now I have created new wallet in mainnet and tried to mint, but I am getting Error running command (re-run needed): AccountNotFound: pubkey=2nXfP... Which I guess is because I don't have sol in it.
So, if I am not wrong with the process, anyone please tell me how much it costs to mint 1000?
You can use this tool to calculate the cost for creating the Candy Machine: https://www.feecalc.live/
A NFT in Solana is represented using 4 accounts.
When you mint 1 NFT you have to pay the rent for all this 4 accounts + gas, this will cost you ~0.012 SOL per NFT.
Knowing that 1 NFT cost 0.012 SOL, then 1000 NFTs will cost you 12 SOL.
I give a really basic explanation of the accounts, I invite you to read some of the accounts that are created here and an explanation on how NFTs are represented on solana here
Each NFT will require a transaction for creating the mint (allocate the data instruction + initialize mint instruction) and allocating metadata
allocate the data
a mint has a size of 82 bytes.
Solana defines a constant cost as 1 byte per year and being rent exempt if you exceed 2 years. so
/// default rental rate in lamports/byte-year:
pub const DEFAULT_LAMPORTS_PER_BYTE_YEAR: u64 = 1_000_000_000 / 100 * 365 / (1024 * 1024);
/// default amount of time (in years) the balance has to include rent for:
pub const DEFAULT_EXEMPTION_THRESHOLD: f64 = 2.0;
this means a mint account will require 82 * DEFAULT_LAMPORTS_PER_BYTES_YEAR * DEFAULT_EXEMPTION_THRESHOLD Lamports
which is around ~0.0014 Sol
you can do the same to calculate the fee for creating a token account (165 bytes) or custom accounts. You can also use getMinimumBalanceForRentExemption
initialize mint instruction
This is an instruction, no data allocation so it's a fixed fee of 5000 Lamports (currently)
allocating metadata
Metaplex metadata account is a data PDA that contains the nft metadata. It doens't have a fixed size so this will depend on how much metadata you allocate.
fee estimation
1000 NFT
82 bytes mint
3 instructions: create mint, initialize mint, allocate metadata
500 bytes metadata account
1000 *
( 0.0014
+ 3 * 5000
+ ( 500 * DEFAULT_LAMPORTS_PER_BYTES_YEAR * DEFAULT_EXEMPTION_THRESHOLD ))
which is around ~5 Sol
Don't take my calculations as 100% correct. I might be missing some instructions and you also have to take into consideration disabling mint authority etc... This is just an example to help, you have to finish the rest.
Apparently I'm too new to comment, so here goes.
Knowing that 1 NFT cost 0.012 SOL, then 1000 NFTs will cost you 12 SOL.
This is a great answer and absolutely correct at the time of posting just stumbled on this and wanted to give an update! Metaplex now adds a .01 SOL fee to each mint tx.
