In the add_liquidity function in liquidity.rs, we have ->

        ...
        let exchange01 = vault_balance0.checked_div(vault_balance1).unwrap();
        let amount_deposit_1 = amount_liq0.checked_mul(exchange01).unwrap();
        ...
        deposit1 = amount_deposit_1; // update liquidity amount ! 

However, In the add_liquidity function in draft.rs, to derive the user_liq1 by using user_liq0, the following is mentioned

        ...      
        // define: depo_user_liq1 = user_liq0 * pool_balance1 / pool_balance0
        ...

I think that the exchange rate in liquidity.rs

        let exchange01 = vault_balance0.checked_div(vault_balance1).unwrap();

should be changed to

        let exchange01 = vault_balance1.checked_div(vault_balance0).unwrap();

How to fix this problems?

Hi,

I have checked and run your source code it's working fine on localnet. When i am integrating with frontend on devnet i can't able to initialize the pool. I have integrating which is like in testcase.

error: failed to send transaction: Transaction simulation failed: Error processing Instruction 2: Program failed to complete.

I don't know why the issue is occurs. Please provide a solution.
