Start a Local Chain

Now that you have the Docker image up and running, we can move on to spinning up a local chain which you can use for development.

Inside your Docker image instance, you can start a local chain by running the following command that runs our test suite, Ultratest.

ultratest -D -n -s

Ultratest automatically sets up a wallet, keys, and all smart contracts. These are necessary to grant you access to the functionality necessary to develop on our stack.

A quick note on the flags above.

-D stops the ultratest framework from closing after tests have ran.

-s enables all system contracts

-n tells the program to not run any tests.

Verifying Chain API is Started

Check http://localhost:8888/v1/chain/get_info to ensure that it is running.
