Choose an Environment

Compare Local, Sequence, and Mainnet before running an XL1 application.

The environment controls which network receives your transactions and whether the tokens have real value.

Environment	Best for	Tokens	Shared with others?
Local	Learning, automated tests, and fast development	Disposable local tokens	No
Sequence	Integration testing with public infrastructure	Sequence test tokens with no monetary value	Yes
Mainnet	Reviewed production applications	Real XL1	Yes

Recommended progression

1. Start locally and confirm the application behaves as expected.

2. Move to Sequence and test the complete workflow with public infrastructure.

3. Review keys, failure handling, costs, and monitoring before considering Mainnet.

Always display the selected environment to the user before signing or submitting a transaction. Never assume that test credentials or test tokens work on another network.
