Services

Yaci DevKit has the following optional services. You may want to enable or disable them based on your application's requirements or the client library you are using.

• Yaci Store : An indexer that provides Blockfrost-compatible API. It's useful if you're using a client library that relies on the Blockfrost API.
• Ogmios : A lightweight bridge interface for cardano-node. It offers a WebSockets API that enables local clients to speak Ouroboros' mini-protocols via JSON/RPC.
• Kupo : Kupo is fast, lightweight and configurable chain-index for the Cardano blockchain.

By default, Yaci Store and Ogmios are enabled. While Yaci Store provides a Blockfrost-compatible API, it relies on Ogmios to support the transaction evaluation endpoint (/api/v1/utils/txs/evaluate). This is useful if you're using a client library that performs online script cost estimation via Blockfrost's transaction evaluation endpoint.

If you enable Kupo, a default wildcard "catch all" matching pattern is pre-configured.

Configuration

Based on your requirements, you should enable or disable services in the env file to minimize the runtime memory footprint of DevKit. Though, you can also enable or disable services using specific commands in yaci-cli, but it's recommended to use the env file for a persistent configuration.

Location of env file

For zip based installation, the env file is located under installation directory config/env.

For curl based installation, the env file is located under $HOME/.yaci-devkit/config/env.

Configuration options

• yaci_store_enabled : Enable or disable Yaci Store service. Default is true.
• ogmios_enabled : Enable or disable Ogmios service. Default is true.
• kupo_enabled : Enable or disable Kupo service. Default is false.
