Minting and burning

Minting
To mint tokens, you can use the nft_batch_mint method:
function nft_batch_mint(
  owner_id: string,
  metadata: TokenMetadata,
  num_to_mint: number,
  royalty_args: RoyaltyArgs | null,
  split_owners: PayoutsMap | null
);
​
type PayoutsMap = Record<string, number>;
type RoyaltyArgs = {
  split_between: PayoutsMap;
  percentage: number;
};
To learn more about TokenMetadata, refer to the corresponding standard​
Due to gas limitations, you cannot mint more than 125 tokens at once.
The PayoutsMap maps from NEAR account IDs to percentages, where each percentage is expressed as an integer between 0 and 10000 (inclusive), where 10000 is equivalent to 100%
As with the PaymoutsMap, the percentage in RoyaltyArgs is expressed as a number between 0 and 10000
Any allowed minter can call this, once they have verified their identity by attaching at least one yoctoNEAR to this method call. You may wish to attach more to cover required storage deposits, as minting increases storage requirements for the contract. The method will not check if sufficient deposits have been made, and it is the responsibility of the store owner and minters to keep their smart contracts sufficiently funded!
Burning
To burn tokens, you can use the nft_batch_burn method:
function nft_batch_burn(token_ids: Array<string>);
This will remove the token from the on-chain storage! This means you can no longer use methos such as nft_token with this token ID, but storage requirements are being decreased by burning. To verify your identity, you are required to attach one yoctoNEAR to the method call.
