|
**This crate is a work in progress and currently is released only as a preview.**
|
|
|
|
While `subxt` is a library for working at the head of a chain (submitting transactions and obtaining the current state), `subxt-historic` is a library for decoding blocks and state that are anywhere in a chain. To broadly summarize the differences:
