Deploy to Your Blockchain

In this guide, you'll use cleos to deploy and test the wax smart contract you created and compiled in the Create a Smart Contract tutorial.

Before You Begin

• nodeos must be running

  nodeos -e -p eosio \
      --plugin eosio::producer_plugin \
      --plugin eosio::chain_api_plugin \
      --plugin eosio::http_plugin \
      --access-control-allow-origin='*' \
      --contracts-console \
      --http-validate-host=false \
      --verbose-http-errors >> nodeos.log 2>&1 &
  

• Your wallet must be Opened and Unlocked

  cleos wallet open
  

  cleos wallet unlock --password PW5KRXKVx25yjL3FvxxY9YxYxxYY9Yxx99yyXTRH8DjppKpD9tKtVz
  

• You must create a WAX Account for your smart contract. Refer to Create Accounts if you haven't completed this step.

Deploy Your Smart Contract

To deploy your smart contract's WASM file to your local blockchain, use cleos set contract from the command line:

Parameter	Example	Description
account	waxsc1	Your smart contract's account.
path	/users/wax-blockchain/wax-cdt/mycontracts/wax	Full path to your WASM file.
permission	-p waxsc1@active	Active or Owner permission for your smart contract's account.

cleos set contract waxsc1 /users/wax-blockchain/wax-cdt/mycontracts/wax -p waxsc1@active

The console prints the following confirmation:

warning: transaction executed locally, but may not be confirmed by the network yet         ]

Your smart contract should now be live on your local blockchain.

Test Your Smart Contract

To test your smart contract, use cleos push action from the command line:

Parameter	Example	Description
account	waxsc1	Your smart contract's account.
action	hi	Name of action.
datastream	'["YourName"]'	Enter your name or any other string.
permission	-p waxsc1@active	Active or Owner permission for your smart contract's account.

cleos push action waxsc1 hi '["YourName"]' -p waxsc1@active

The console prints the following:

executed transaction: 6a0b1489d903f2cacc6480830358f07aaf65b20bf1d7e855dc20097f4d64dc52  104 bytes  1727 us
#        waxsc2 <= waxsc2::hi                   {"nm":"YourName"}
>> Name : YourName
warning: transaction executed locally, but may not be confirmed by the network yet         ]

If you receive an error that the transaction took too long, run cleos push action again. If you still receive an error, try restarting nodeos.
