Constellation provides developers with a full featured testnet to test applications and metagraphs before they're ready for the production environment. The testnet has all of the same features as mainnet and can therefore be used to validate application integrations in a realistic way.

Developing a metagraph

Metagraph developers may use testnet as they're nearing production readiness. For initial development, developing on your own test cluster is recommended. See Deploying to Testnet.

Connecting to Testnet

The following urls can used to access testnet:

See Available APIs for detailed information on available endpoints.

The faucet can be accessed at:
