RPC Client

This client is the defacto client for submitting blobs to NEAR. These crates allow a client to interact with the blob store. It can be treated as a "black box", where blobs go in, and [transaction_id ++ commitment] emerges.

The da-rpc crate is the rust client, which anyone can use if they prefer rust in their application. The responsibility of this client is to provide a simple interface for interacting with NEAR DA.

The da-rpc-sys crate is the FFI client binding for use by non-rust applications. This calls through to da-rpc to interact with the blob store, with some additional black box functionality for dealing with pointers wrangling and such.

The da-rpc-go crate is the go client bindings for use by non-rust applications, and this calls through to da-rpc-sys, which provides another application-level layer for easy interaction with the bindings.


Diagram

The below diagrams outline how a rollup will interact with DA depending on their architecture.

Rust

Golang, or anything CFFI compatible

This diagram outlines how rollups written in golang would interact with the go rpc client.
