Hello, I don’t quite understand what your problem is, perhaps incorrect type casting in comparison

i want to wait for confirmation transaction

Hi, try a finally block to mutate the state after the transaction is completed

try {
      return await contract.methods
        .someContractFunction()
        .send({ from: account.account, value: priceInWei });
    } catch (error) { 
       throw new Error(error.message);
    } finally {
         // immediately update state after tx
    }
