js-moi-sdk is a Javascript/Typescript implementation of a feature-rich library designed to seamlessly interact with the MOI Protocol and its extensive ecosystem. It provides a convenient interface for interacting with the MOI protocol, allowing developers to create, sign, and send interactions, retrieve account balances, access interaction history, and more.


Install the latest release using the following command.

npm install js-moi-sdk


    import { JsonRpcProvider } from "js-moi-sdk";

    (async() => {
        const provider = new JsonRpcProvider("http://localhost:1600");
        const address  = "0xf350520ebca8c09efa19f2ed13012ceb70b2e710241748f4ac11bd4a9b43949b";
        const tesseract = await provider.getTesseract(address, true);

Sub Packages

The js-moi-sdk package consists of several sub-packages, each offering independent functionality that can be utilized separately to enhance your development experience.

  • js-moi-constants This package includes common constants used within the js-moi-sdk ecosystem. These constants provide predefined values for various aspects of MOI, making it easier to work with the protocol.

  • js-moi-providers This package enables you to connect to MOI nodes and retrieve blockchain data, such as account balances and interaction history. It provides an interface for interacting with the MOI protocol and fetching information from the network.

  • js-moi-signer This package represents an MOI account with the ability to sign interactions and messages for cryptographic proof. It provides the necessary tools to sign interactions securely and authenticate interactions on the MOI network.

  • js-moi-bip39 This package offers the features necessary for generating and handling mnemonic phrases in accordance with the BIP39 standard.

  • js-moi-hdnode This package represents a Hierarchical Deterministic (HD) Node for cryptographic key generation and derivation. It allows you to generate and manage keys within a hierarchical structure, providing enhanced security and flexibility.

  • js-moi-wallet This package represents a Hierarchical Deterministic Wallet capable of signing interactions and managing accounts. It provides a convenient interface for managing multiple accounts, generating keys, and securely signing interactions.

  • js-moi-manifest This package encodes and decodes data according to the MOI Manifest specification, facilitating interaction with logic objects. It simplifies the process of encoding and decoding data structures, making it easier to work with MOI logic objects.

  • js-moi-logic This package simplifies interaction with MOI logic objects by offering deployment, interaction, and querying capabilities. It provides a higher-level interface for working with MOI logic, allowing you to deploy logic objects, send interactions, and retrieve results.

  • js-moi-utils This package offers a comprehensive set of tools and functions to enhance development with MOI. It provides utility functions that simplify common tasks, making your development experience smoother and more efficient.
