IOTA Notarization Toolkit

Introduction

This repository contains the IOTA Notarization Toolkit, a set of IOTA ledger tools for verifiable on-chain data workflows.

The toolkit includes:

• Single Notarization Use this for individual locked or dynamic notarizations of arbitrary data, documents, hashes, or latest-state records.
• Audit Trails Use this for structured record histories with sequential entries, role-based access control, locking, and tagging.

Each toolkit component is available as:

• Move Package for the on-chain contracts
• Rust Package for typed client access and transaction builders
• TypeScript/JS Package using wasm bindings for the above-mentioned Rust package

Where To Start

I want a single notarized record

Use Single Notarization when your main need is proving the existence, integrity, or latest state of one notarized object on-chain.

• Single Notarization Rust Package
• Single Notarization Move Package
• Single Notarization Wasm Package
• Single Notarization examples

I want an audit trail

Use Audit Trails when you need a structured record history with permissions, capabilities, tagging, and write or delete controls.

• Audit Trails Rust Package
• Audit Trails Move Package
• Audit Trails Wasm Package
• Audit Trails examples

I want the on-chain contracts

• Single Notarization Move
• Audit Trails Move

I want to build an application

• Single Notarization Rust
• Audit Trails Rust
• Single Notarization Wasm
• Audit Trails Wasm

Toolkit Components

Component	Best for	Move Package	Rust Package	Wasm Package
Single Notarization	Individual locked or dynamic notarizations for documents, hashes, and state	notarization-move	notarization-rs	notarization_wasm
Audit Trails	Shared sequential records with roles, capabilities, tagging, and locking	audit-trail-move	audit-trail-rs	audit_trail_wasm

Which one should I use?

Need	Best fit
Locked proof object for arbitrary data	Single Notarization
Dynamic latest-state notarization flow	Single Notarization
Shared sequential records with roles, capabilities, and record tag policy	Audit Trails
Team or system audit log with governance and operational controls	Audit Trails
