Developer Tools

We believe blockchain adoption can be accelerated by improving developer experience. Explore our open-source tools, components, and frameworks, designed to streamline dApp development.
Rust-native Cardano building blocks

Rust-native Cardano building blocks

0
An expanding collection of modules that re-implements common Ouroboros / Cardano logic in native Rust. It is meant to be used as a base layer to facilitate the development of higher-level use-cases.
The tail of Cardano

The tail of Cardano

0
A backend tool that connects on-chain data with stream-processing infrastructure (Kafka, Elasticsearch, FaaS). It allows the creation of off-chain applications that 'react' to on-chain events.
Scrolls

Cardano Cache

0
A backend tool for building and maintaining read-optimized collections of Cardano's on-chain entities. It crawls the history of the chain and aggregates all data to reflect the current state of affairs.
Dolos

A Cardano data node in Rust

0
A new type of Cardano node, fine-tuned to solve a very narrow scope: keeping an updated copy of the ledger and replying to queries from trusted clients, while requiring a small fraction of the resources.
Mumak

Postgres extension to process CBOR

Mumak is a PostgreSQL extension that provides several custom functions to interact with Cardano CBOR data directly on the database.
Balius

Cardano Headless dApps

Coming soon
Headless dApp Framework. A friendly SDK for off-chain development, for building self-contained, portable logic for reading and participating in on-chain smart contract protocols.
Boros

Smart transaction submission

Coming soon
Backend component that serves as a smart, massive pipeline for resilient and performant transaction submissions. Queue transactions via three different API mechanisms (HTTP, WebSockets and gRPC).
CShell

A cardano wallet in your terminal

Coming soon
A light, self-custodial, open-source wallet that runs on the terminal, enabling new capabilities forpower-users around automation and programability which can't be find in other wallets.
Telchar

Registry of Plutus bluprints

Coming soon
A public registry to search and find Plutus blueprint definitions for protocols that were authored by third parties. Codegen templates to turn a blueprint into "typings" for popular transaction builder libraries.
Griffin

Plutus VM on a Substrate node

Coming soon
A framework for building Substrate-based app-chains, on a Substrate node that uses an UTxO-based ledger and a Plutus VM, allowing the execution of Cardano-like dApps in Substrate-based networks.
