+### `mintNFT(I ImmutableData, a AgentID, C CollectionID, w WithdrawOnMint)`
+
+Mints an NFT with ImmutableData `I` that will be owned by the AgentID `a`.
+It's possible to mint as part of a collection `C` (the caller must be the owner of the collection NFT to mint new NFTs as part of said collection).
+The mint can be done directly to any L1 address (it is not necessary for the target to have an account on the chain)
+
+#### Parameters
+
+- `I` (`[]byte`): ImmutableData for the NFT.
+- `a` (`AgentID`): AgentID that will be the owner of the NFT.
+- `C` (optional `NFTID` - default empty): collectionID (NFTID) for the NFT.
+- `w` (optional `bool` - default `false`): whether to withdrawal the NFT in the minting step (can only be `true` when the targetAgentID is a L1 address).
+
+#### Returns
+
+- `D` (`MintID`): the internal ID of the NFT at the time of minting that can be used by users/contracts to obtain the resulting NFTID on the next block
