Introduction

Atlas is an all-in-one, Haskell-native application backend for writing off-chain code for on-chain Plutus smart contracts. Atlas has been designed by Genius Yield (opens in a new tab), in collaboration with MLabs (opens in a new tab), Well-Typed (opens in a new tab) and Plank (opens in a new tab).

Features

Easily build transactions

Use an intuitive API to abstract away the complexity around building transactions, balancing UTxOs, and interfacing with Plutus smart contracts.

Leverage first-class Haskell

Write type-safe abstractions, harnessing the power & security of Haskell.

Utilize modular data providers

Query ledger state information from remote provider such as Maestro (opens in a new tab), Blockfrost (opens in a new tab) or from your own node with the help of Kupo (opens in a new tab). You can also build and contribute your own data provider!

Test extensively

Use Atlas' test harness to write realistic test harness, which can be run against either an emulator or a private Cardano network. Atlas offers a unified testing approach and the same test code can seamlessly execute on both an emulated mock ledger and an actual private Cardano test network.

Stay up to date

Benefit from Cardano's latest innovations such as Reference Inputs, Inline Datums, Reference Scripts, governance actions and so on.
