Distributed Ledger​

This monorepo brings together reusable ledger utilities and supporting tools for building, testing, and deploying distributed ledger workloads. The packages and applications are designed to work together so teams can move from integration code to deployment workflows with fewer bespoke steps. See More

Wallet​

This repository provides a focused set of wallet building blocks and a companion command-line tool for practical operational workflows. The libraries define shared connector contracts, add storage-backed implementations for local and test scenarios, and provide network-backed implementations for interaction with IOTA infrastructure. See More

Identity​

This repository brings together the core building blocks needed to design and run decentralised identity workflows across different environments. It combines shared models, storage and network connectors, service contracts, a REST client, and a command line tool so teams can implement consistent identity behaviour without rebuilding the same foundation in each project. See More

NFT​

This repository provides modular components for creating, managing, and integrating non-fungible tokens across application, service, and connector layers. The packages are designed to share a consistent contract model so teams can build tooling, APIs, and command line flows without duplicating core NFT logic. See More

Verifiable Storage​

This repository provides a modular set of components for creating, exposing, and consuming verifiable storage capabilities across different environments. The packages work together to model shared contracts, connect to storage back ends, and expose consistent service interfaces for application integration. See More

Immutable Proof​

This repository provides a focused set of components for creating, storing, and validating immutable proof records across distributed systems. The modules are designed to work together so teams can model proof data, run background processing, expose service endpoints, and integrate through a dedicated client. See More

Attestation​

This repository contains modular components for creating, verifying, transferring, and consuming attestations across different integration styles. The packages are designed to work together through shared contracts, so teams can compose model definitions, connector implementations, service orchestration, and client access without duplicating core logic. See More

Auditable Item Graph​
