Introduction

Reactive Blockchain RPC Calls

multichain is a low-level library that facilitates reactive blockchain RPC calls, leveraging the cells library - a simplified reactive functional library inspired by spreadsheet functionalities.

Problem Statement

Decentralized applications (dApps) often face challenges when connecting to blockchain RPCs due to asynchronous operations that result in significant delays. Common issues include:

1. Difficulty in implementing multicall aggregation to optimize RPC calls.
2. Lack of default mechanisms for retrying or dispatching calls to multiple RPC nodes.
3. Inefficient caching of immutable data, leading to unnecessary re-queries.
4. The complexity of integrating reactive, functional programming with existing imperative libraries.

Solution

multichain addresses these challenges by providing a multi-chain cache for RPC queries and their responses, built around reactive functional programming principles. Each response is treated as a cell, allowing predefined computational flows that execute automatically when the data becomes available.

Design & Philosophy

multichain is crafted to offer fine-grained control for developers and dApp implementors, with plans to release a higher-level consumer interface to simplify rapid dApp development.

We aim for ease of use and correction, so chasing down any bug is our top priority.
