How can I send Sui when calling an entry smart contract function using SUI SDK not as gas amount (ofc I am assuming I would send gas separately)? What would the entry smart contract would look like, that expect SUI?

The function in your package/module (smart contract) would have argument like `in_coin:Coin<SUI>`

Assuming TS-SDK it would be `tx.object("0x.....")` where ‘0x…’ is replaced with the coin ID

If I split a coin like this:

```auto
const txb = new TransactionBlock();
const [coin] = txb.splitCoins(txb.gas, [txb.pure(100000)]);

```

Should I pass only the `coin` variable

Yes, the result(s) of a splitCoins can be used in any subsequent command that takes either a coin or object.

Should I need to set the gas amount before splitting the coin?

If you mean setting the transaction gas budget, not necessary for split coin. But there are a number of variables to consider.

This question was from months ago so I presume you’ve worked it out.
