Deployment and interaction
You now have the wasm binary ready. It's time to deploy it to the Archway (Constantine) testnet and begin interacting with your smart contract. You can use the archwayd CLI, Archway Developer CLI, or the arch3.js, depending on your preference.
Deploy contract
In the Compile Contract page, we generated a wasm binary executable. You can upload the code to the blockchain, and once the process is complete, you can download the bytecode for verification purposes.
Deploy using archwayd
Now you will store the wasm bytecode of the cw_namespace contract on chain and obtain the code id. This code id will be used later to create an instance of the cw_namespace contract.
Change mywallet to the name of the wallet you created in the Setting up environment page. Execute the following commands to store the contract on chain:
mainnet
testnet
RES=$(archwayd tx wasm store artifacts/cw_nameservice.wasm --from mywallet --node https://rpc.mainnet.archway.io:443 --chain-id archway-1 --gas auto --gas-prices $(archwayd q rewards estimate-fees 1 --node 'https://rpc.mainnet.archway.io:443' --output json | jq -r '.gas_unit_price | (.amount + .denom)') --gas-adjustment 1.3 -y --output json -b block)The response contains the Code Id of the uploaded wasm binary:
echo $RESThe following is an easier way to get the Code Id from the response
CODE_ID=$(echo $RES | jq -r '.logs[0].events[] | select(.type=="store_code") | .attributes[] | select(.key=="code_id") | .value')echo $CODE_IDYou can see the list of contracts instantiated using the CODE_ID generated above by executing the following command:
mainnet
testnet
archwayd query wasm list-contract-by-code $CODE_ID --node https://rpc.mainnet.archway.io:443 --output jsonThe response should be an empty list since no contracts have been instantiated yet.
{"contracts":[],"pagination":{"next_key":null,"total":"0"}}Before you instantiate a contract using the Code Id and interact with it, let's verify if the code stored on the blockchain is indeed the cw_namespace.wasm binary you uploaded.
Download the wasm binary from the chain and compare it to the original one:
mainnet
testnet
archwayd query wasm code $CODE_ID --node https://rpc.mainnet.archway.io:443 download.wasm --chain-id archway-1The two binaries should be identical:
diff artifacts/cw_nameservice.wasm download.wasmIf the diff command yields an empty output, this indicates that the two files being compared are identical.
Deploy using archway developer cli
If your contract was created using the archway new command, you can deploy the contract using the following command:
archway storeFor details on how to create a CosmWasm project with the Archway Developer CLI, see Creating a project.
Instantiating the contract
You can now create an instance of the wasm contract. After instantiation, you can make queries and execute transactions.
Instantiate using archwayd
mainnet
testnet
# Prepare the instantiation messageINIT='{"purchase_price":{"amount":"100","denom":"aconst"},"transfer_price":{"amount":"999","denom":"aconst"}}'# Instantiate the contractarchwayd tx wasm instantiate $CODE_ID "$INIT" --from mywallet --label "name service" --node https://rpc.mainnet.archway.io:443 --chain-id archway-1 --gas auto --gas-prices $(archwayd q rewards estimate-fees 1 --node 'https://rpc.mainnet.archway.io:443' --output json | jq -r '.gas_unit_price | (.amount + .denom)') --gas-adjustment 1.3 -y --no-admin# Check the contract details and account balancearchwayd query wasm list-contract-by-code $CODE_ID --node https://rpc.mainnet.archway.io:443 --output jsonCONTRACT=$(archwayd query wasm list-contract-by-code $CODE_ID --node https://rpc.mainnet.archway.io:443 --output json | jq -r '.contracts[-1]')echo $CONTRACT# See the contract detailsarchwayd query wasm contract $CONTRACT --node https://rpc.mainnet.archway.io:443 --chain-id archway-1# Check the contract balancearchwayd query bank balances $CONTRACT --node https://rpc.mainnet.archway.io:443 --chain-id archway-1# Upon instantiation the cw_nameservice contract will store the instatiation message data in the contract's storage with the storage key "config".# Query the entire contract statearchwayd query wasm contract-state all $CONTRACT --node https://rpc.mainnet.archway.io:443 --chain-id archway-1Contract Interaction
Now that the contract is instantiated, you can register a name and transfer it to another address by paying the transfer fee.
