WORKSPACES

Workspaces is a no-setup VSCode development environment that runs in your
browser.

ACCESS CARDANO NODE

Workspaces runs inside a private network which has access to the Cardano nodes
running on the same cluster. Each Cardano node in the cluster has its own local
domain name that can be used to dynamically resolve its location.

QUERY THE LEDGER STATE WITH DB-SYNC

Workspaces offers a PostgreSQL instance running within the private network of
the workspace that contains updated data from DB-Sync. It's as simple as picking
your favorite PostgreSQL client library.

UNIX SOCKETS AND NODE-TO-CLIENT PROTOCOLS

Upon startup, the workspace automatically mounts the corresponding socket path
of the cardano node into a fixed location within the file system.

Workspaces does the infrastructure heavy lifting for you, no need to manually
set up Cabal, Nix, GHC. Enabling you to focus on building your dApp.

HASKELL HELLO WORLD

An empty Haskell project ready to code with all required dependencies already
installed and all of the recommended VS Code extensions available by default..
It contains some very basic code with a 'hello world' example.

CARDANO CLI TUTORIAL

A tutorial that shows you how to use the Cardano CLI to execute operations
directly against the Cardano node.

by TxPipe


PALLAS BLOCK DOWNLOAD

A very basic example of how to use Pallas rust library to connect to the Cardano
Node running on Demeter's cluster by using low-level Ouroboros mini-protocols.

OGMIOS TYPESCRIPT CLIENT

A Demeter starter kit that shows how to use Ogmios' Typescript client.

by TxPipe + CardanoSolutions


PLUTUSV2 HELLO WORLD

This is a bare bones PlutusV2 smart-contract template. The goal is to provide
the minimum expression of a PlutusV2 project to be used as starting point to
build more complex contracts. Demonstrating one of the new features of PlutusV2!

FULLY-SYNCED CARDANO NODES

This feature provides access to a fully-synced, mutualized Cardano Node that can
be used to interface with the blockchain. The node is managed as part of the
shared infrastructure of the Tilth cluster. It can be accessed from a workspace
through unix sockets or as a relay node though an internal TCP socket.

ACCESS REAL-TIME & HISTORICAL BLOCKCHAIN DATA WITH DB SYNC

With DB Sync in Demeter you get a PostgreSQL database with all real time and
historical Cardano blockchain data. Write SQL queries directly against the
database schema, or make use of your favorite libraries for interacting with an
SQL database.

Demeter includes Starter kits such as the Stake Pool Explorer that enable a
newcomer to the UTXO ledger model to explore and learn hands-on. We also offer a
comfortable graphical database schema offering the advanced developer a cheat
sheet and the novice Cardano developer another tool to explore what data is
stored on the blockchain.

https://demeter.run



OBSERVE THE CARDANO BLOCKCHAIN EFFORTLESSLY WITH OGMIOS

Ogmios is a lightweight bridge interface for observing the Cardano blockchain.

Ogmios offers developers a WebSocket API that enables local clients to speak
Ouroboros' mini-protocols via JSON/RPC. Ogmios is a FOSS tool, created and built
by Cardano Solutions.

https://demeter.run



PUT TRANSACTIONS ON-CHAIN WITH SUBMIT API

Once the transaction has been built, make use of our simple Submit API tool to
put it on the blockchain.

The Submit API is an HTTP service that accepts pre-signed, CBOR-encoded
transactions and submits them to a local running node. Submit API is one
component within the context of the larger Cardano Node.

https://demeter.run



MONITOR ON-CHAIN EVENTS WITH CARDANO WEBHOOKS

Subscribe to critical events happening on the Cardano blockchain. Inform your
users real-time when an important transaction took place or take action when a
rollback happened. The Webhooks feature allows you to receive a POST request
with the updated data.

https://demeter.run



LAUNCH WITH CONTAINERS

Get to the market fast by hosting the off-chain components of your dApp with
Demeter.

We provide you detailed instructions on how to package your application so that
it's hosted side-by-side with the rest of the required Cardano infrastructure.
