Setup

The following steps describe only a minimal setup. You will need to perform additional steps depending on the module you want to work on — refer to its dedicated page.

Add dependencies

Version Catalog (recommended)

Add the Ledger SDK version catalog to your settings.gradle.kts:


dependencyResolutionManagement {
    versionCatalogs {
        create("ledger") {
            from("io.github.ledgerhq:sdk-version-catalog:<version>")
        }
    }
}

Device Management Kit

Using the Version Catalog


dependencies {
    implementation(platform(ledger.bom))
    implementation(ledger.device.management.kit)
}

Using the BOM only


dependencies {
    implementation(platform("io.github.ledgerhq:sdk-bom:<version>"))
    implementation("io.github.ledgerhq:device-management-kit")
}

Direct dependency


dependencies {
    implementation("io.github.ledgerhq:device-management-kit:<version>")
}

iOS (Swift Package Manager)

Add the LedgerDMK XCFramework to your Xcode project or Package.swift.

Ethereum Signer

ℹ️

This module depends on the device-management-kit module, which must be installed first.

Using the Version Catalog


dependencies {
    implementation(platform(ledger.bom))
    implementation(ledger.device.management.kit)
    implementation(ledger.device.signer.kit.ethereum)
}

Using the BOM only


dependencies {
    implementation(platform("io.github.ledgerhq:sdk-bom:<version>"))
    implementation("io.github.ledgerhq:device-management-kit")
    implementation("io.github.ledgerhq:device-signer-kit-ethereum")
}

Direct dependency


dependencies {
    implementation("io.github.ledgerhq:device-management-kit:<version>")
    implementation("io.github.ledgerhq:device-signer-kit-ethereum:<version>")
}

iOS (Swift Package Manager)

Add the SignerEth XCFramework to your Xcode project or Package.swift.
