The Exchange Chain is the default asset blockchain on Avalanche® and enables the creation of new assets, exchanging between assets, and cross-Subnet transfers. This blockchain is for applications that don’t require total ordering (for total ordering, use the Contract Chain). The Exchange Chain implements the Avalanche consensus protocol.

Note that when using these addresses, it is best practice to follow case sensitivity.
