Running your Application

Synopsis

Congrats!! You built your first network already. You are ready to run a local testnet environment to verify it works.

• Building your application executable
• Running a local testnet
• Interacting with the network

Launch The Network

Use the sh-testnet command (short for shell testnet) to quickly build your application, generate example wallet accounts, and start the local network on your machine.

# Run a quick shell testnet
make sh-testnet

The chain will begin to create (mint) new blocks. You can see the logs of the network running in the terminal.

Interact Set Name

Using the newly built binary (rolld from the --bin flag when the chain was created), you are going to execute the set transaction to your name. In this example, use "alice". This links account acc1 address to the desired name in the keeper.

Then, resolve this name with the nameservice lookup. $(rolld keys show acc1 -a) is a substitute for the acc1's address. You can also use just roll1hj5fveer5cjtn4wd6wstzugjfdxzl0xpg2te87 here.

rolld tx nameservice set alice --from=acc1 --yes

# You can verify this transaction was successful
# By querying it's unique ID.
rolld q tx 565CE77057ACBF6FB5D174231455E61E65009CD628971937C19201328E0A1FFD

Interaction Get Name

Now you are going to get the name of a wallet. A nested command $(rolld keys show acc1 -a) gets the unique address of the acc1 account added when you started the testnet.

rolld q nameservice resolve roll1efd63aw40lxf3n4mhf7dzhjkr453axur57cawh --output=json

rolld q nameservice resolve $(rolld keys show acc1 -a) --output=json

The expected result should be:

{
  "name": "alice"
}

note

When you are ready to stop the testnet, you can use ctrl + c or killall -9 rolld.

Your network is now running and you have successfully set and resolved a name! 🎉
