README
subxt-historic
This create 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:
| Feature | subxt | subxt-historic |
|---|---|---|
| Block access | Head of chain | Any block in chain |
| Connection to chain | Light client or RPC node | Archive RPC nodes only |
| Transaction submission | Yes | No |
| Metadata compatibility | V14 and newer | Any version |
