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.

Build quickly, scale comfortably, eject whenever!

At Demeter, we believe in the merits of decentralization. No vendor lock-in. Eject your project into your own infrastructure at any time.

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.

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.

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.

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.
