Token transfer

When transferring tokens, it is essential to include checks and validations to prevent accidental loss. For instance, developers can verify that the recipient account exists and is valid before initiating the transfer. Here’s an example in Rust using the NEAR SDK:

#![allow(unused)]
fn main() {
pub fn transfer_tokens2(self, recipient: near_sdk::AccountId, amount: near_sdk::Balance) {
	assert!(
		env::is_valid_account_id(&recipient.as_bytes()),
		"Invalid recipient account"
	);
	let sender_balance = account_balance();
	assert!(sender_balance >= amount, "Insufficient balance"); // Perform the token tra
	Promise::new(recipient).transfer(amount);
}
}
