Can modules generate multiple coins onchain seamlessly?
I’m working on a module for prediction markets and need it to generate coins onchain through a factory class in a permissionless and verifiable way. Currently, modules have limitations like only one coin per module due to One Time Witness, which means I had to create an equivalent coin standard that users' wallets don't recognize as a coin. Can we resolve this in the next update?

What's a native function and can we call them directly?
I've come across the term 'native function' in Move but can't find detailed information about it. I heard that they're declared in Move but defined externally, often in Rust. Does that mean they are internal functions that can't be called directly by wallets or other modules?

How to ensure only NFT owner can transfer it in a contract?
Hey everyone! I'm working on implementing an NFT contract and want to make sure that only the rightful owner of the NFT can transfer it. I have this function for transferring: public fun transfer( nft: DevNetNFT, recipient: address, _: &mut TxContext ) { transfer::public_transfer(nft, recipient) } Is this checking done within the public_transfer method, or do I need to add additional logic?
