Modules

In 0.4.0 and later, the library has been divided into smaller modules. These modules can be added to a project based on requirement.

Group Id: com.bloxbean.cardano

For simple setup, you can use cardano-client-lib and one of the backend provider as dependency.

Modules	Artifact Id	Description
cardano-client-lib	cardano-client-lib	This is a top level module which includes all other modules except backend provider modules. (Recommended for most application)
Backend Api	cardano-client-backend	Defines backend apis which are implemented by provider specific module.
Blockfrost Backend	cardano-client-backend-blockfrost	Provides integration with Blockfrost
Koios Backend	cardano-client-backend-koios	Provides integration with Koios
Ogmios/Kupo Backend	cardano-client-backend-ogmios	Provides integration with Ogmios and Kupo . Supported Apis : submitTransaction, evaluateTx, Kupo support (UtxoService)

For fine-grained dependency management, add one or more below modules as required.

Modules	Artifact Id	Description
common	cardano-client-common	Contains common utilities (HexUtil, JsonUtil, Cbor Utils etc). This module doesn’t depend on any other module. Dependencies: None
crypto	cardano-client-crypto	Provides implementation for standards like Bip32, Bip39, CIP1852 and other crypto primitives Dependencies: common
address	cardano-client-address	Supports derivation of various types of Cardano addresses (Base, Enterprise, Pointer, Stake etc) Dependencies: common, crypto, transaction-common
metadata	cardano-client-metadata	Provides simple api to generate and serialize generic metadata Dependencies: common, crypto
transaction-common	cardano-client-transaction-common	A small module with some transaction specific common classes which are required in other modules. This module is there for backward compatibility. So you should not add this module directly in your application. Dependencies: common, crypto
core	cardano-client-core	Contains low level transaction serialization logic and other common apis / interfaces (Account, Coin selections, UtxoSupplier, ProtocolParamSupplier etc.). Also contains high-level api like PaymentTransaction for backward compatibility. But HL api may be removed to a separate module in future release Dependencies: common, crypto, transaction-common, address, metadata
function	cardano-client-function	Provides Composable Function Apis. A simple, flexible way to build transactions through re-usable functions. Dependencies: core
cip	cardano-client-cip	A umbrella module which provides a simple way to get available cip implementations (cip25, cip8 etc.) Dependencies: cip8, cip20, cip25, cip27, cip30
cip8	cardano-client-cip8	CIP 8 - Message Signing Dependencies: common, crypto
cip20	cardano-client-cip20	CIP 20 - Transaction message/comment metadata Dependencies: metadata
cip25	cardano-client-cip25	CIP 25 - Media NFT Metadata Standard Dependencies: metadata
cip27	cardano-client-cip27	CIP 27 - CNFT Community Royalties Standard Dependencies: cip25
cip30	cardano-client-cip30	CIP 30 - Cardano dApp-Wallet Web Bridge Dependencies: cip8, core
