CounterV2 Deployment Steps

Step 1: Create The Account Entry

sncast account create --name Yusrah --network sepolia

Save the generated account address and fund it with Sepolia tokens for fees.

Step 2: Deploy The Account

sncast account deploy --name Yusrah --network sepolia

Step 3: List Accounts

sncast account list

Save the address for the Yusrah account.

Yusrah's acc. address 0x72658e0505e77137829e255912c52f8ca0ae73de5dde8332686b1adac3034f0

Step 4: Go Into The Contract Package

cd ~/Desktop/cairo-begining/cairo-bootcamp-6/starknet_contracts

Step 5: Build The Contract

scarb build

Step 6: Declare CounterV2

sncast --account Yusrah \
  declare \
  --contract-name CounterV2 \
  --network sepolia \
  --wait

Save the class_hash from the output.

class harsh 0x1e3a5b348490a07cea9f2788b81e46132c107724621e462494a5d20b67d458d

Step 7: Deploy CounterV2

Replace:

• PASTE_CLASS_HASH_HERE
• PASTE_YUSRAH_ADDRESS_HERE

sncast --account Yusrah \
  deploy \
  --class-hash PASTE_CLASS_HASH_HERE \
  --constructor-calldata PASTE_YUSRAH_ADDRESS_HERE \
  --network sepolia \
  --wait

Save the deployed contract_address.

contract address 0x031e9847e60b0e7224c095cd45e260aa96daa0cec22960a8ab1cc51949997f36

Step 8: Verify The Owner

Replace PASTE_CONTRACT_ADDRESS_HERE.

sncast call \
  --contract-address PASTE_CONTRACT_ADDRESS_HERE \
  --function get_owner \
  --network sepolia

Step 9: Verify The Initial Count

sncast call \
  --contract-address PASTE_CONTRACT_ADDRESS_HERE \
  --function get_count \
  --network sepolia

Expected:

0

Step 10: Increase The Count By 10

sncast --account Yusrah \
  invoke \
  --contract-address PASTE_CONTRACT_ADDRESS_HERE \
  --function increase_count \
  --calldata 10 \
  --network sepolia \
  --wait

Step 11: Verify The Count After Increasing

sncast call \
  --contract-address PASTE_CONTRACT_ADDRESS_HERE \
  --function get_count \
  --network sepolia

Expected:

10

Step 12: Reduce The Count By 4

sncast --account Yusrah \
  invoke \
  --contract-address PASTE_CONTRACT_ADDRESS_HERE \
  --function reduce_count \
  --calldata 4 \
  --network sepolia \
  --wait

Step 13: Verify The Count After Reducing

sncast call \
  --contract-address PASTE_CONTRACT_ADDRESS_HERE \
  --function get_count \
  --network sepolia

Expected:

6

Step 14: Demo Subtraction Underflow Protection

sncast --account Yusrah \
  invoke \
  --contract-address PASTE_CONTRACT_ADDRESS_HERE \
  --function reduce_count \
  --calldata 200 \
  --network sepolia \
  --wait

Expected:

An error because the subtraction underflows.

Step 15: Demo Non-Owner Rejection

Replace OTHER_ACCOUNT_NAME.

sncast --account OTHER_ACCOUNT_NAME \
  invoke \
  --contract-address PASTE_CONTRACT_ADDRESS_HERE \
  --function increase_count \
  --calldata 1 \
  --network sepolia \
  --wait

Expected:

An error because the caller is not the owner.

e.g of non owner address 0x00A879C0fEf9C803041Ab7524859879B5d68684f413890401566367ae38a3a10
