Stuck on the starknet cairo tutorial, fret not, let me give you a quick walk through and guide you through the 1st 3 tutorialshttps://starknet.crew3.xyz/questboard Step 1 : Install Argent wallet, and create a new wallet, remember to save you seed word https://www.argent.xyz/ Step 2 :Switch the wallet to Goerli network and get some Goerli ETH from the faucet https://faucet.goerli.starknet.io/ Step 3: Open the github of the quest and read through it https://github.com/l-henri/starknet-cairo-101 Step 4: I will now bring you through these 3 exercisesExercise 1 : General Syntax Step 5 : Open both EX01 and Link on 2 diff tabs on your browser Step 6 : Look at the code, in hashes gives you the hint on what you must do, which is to trigger a claim_points function to get the points for each exerciseStep 7: Now go to the write contract tab, you will notice that the first exercise does not require any input an you just need to click on the transactStep 8: Now click on transact and wait for 5-10 mins for the transaction to be mineExercise 2 : Storage variable, getter, assert Step 9 : For exercise 2, open up the 2 tabs of github and voyager again on 2 new tabs Step 10 : The voyager link showed that you will need to input a variable called my_valueStep 11 : The code snippet shows that my_value is = my_secret_valueStep 12 : Now switch over to read contract on voyager tabStep 13 : You will notice that there is a read function where you can query the secret valueStep 14 : Query out the value in step 13 and then input it into claim points and click on transactStep 15: Wait 5 - 10 mins for the transaction to be mined. Exercise 3 : Reading and writing storage variables Step 16 : Open up the 2 links for github and voyager for exercise 3 in 2 diff tabs Step 17 : A look at the code shows that a variable which is counter must be = 7 before the claim can be doneStep 18 : On the voyager front there are 3 functions which might manipulate the counter variableStep 19 : On the code, it shows that increment will increase counter by 2 and decrement will decrease counter by 1, so in order to hit 7, we will need to reset counter to 0 first , then increment counter 4 times and then decrement counter 1 time.
