Advanced tools
This repository contains JavaScript bindings for interacting with the Concordium Ledger App. It provides various functions to handle transactions, contracts, and credentials.
To use this SDK, install it via npm:
npm install @blooo/hw-app-concordium
Concordium API
transport Transport Below are examples of how to use the various functions provided by the SDK.
path string - A BIP32 path.display boolean - Flag to show display.signedKey boolean - Flag to sign key.publicKey string - The public key.signedPublicKey string - Only if signedKey is true. The signed public key.const { publicKey } = await ccd.getPublicKey("44/919/0/0/0/0", true, false);
Or
const { publicKey, signedPublicKey } = await ccd.getPublicKey("44/919/0/0/0/0", true, true);
data IExportPrivateKeyData - The data required for exporting the private key.exportType ExportType - The type of export, either PRF_KEY_SEED or PRF_KEY.mode Mode - The mode, either DISPLAY, NO_DISPLAY, or EXPORT_CRED_ID.privateKey string - The private key.credentialId string - Only if mode is EXPORT_CRED_ID. The credential ID.const { privateKey } = await ccd.exportPrivateKeyLegacy(data, exportType, mode);
Or
const { privateKey, credentialId } = await ccd.exportPrivateKeyLegacy(data, exportType, mode);
data IExportPrivateKeyData - The data required for exporting the private key.exportType ExportType - The type of export, either PRF_KEY_SEED or PRF_KEY.mode Mode - The mode, either DISPLAY, NO_DISPLAY, or EXPORT_CRED_ID.privateKey string - The private key.credentialId string - Only if mode is EXPORT_CRED_ID. The credential ID.const { privateKey } = await ccd.exportPrivateKeyNew(data, exportType, mode);
Or
const { privateKey, credentialId } = await ccd.exportPrivateKeyNew(data, exportType, mode);
isLegacy boolean - Flag to indicate if the legacy mode is used.id number - The identity number.cred number - The credential number.idp number - Mandatory only if isLegacy is false. The identity provider number.status string - The status of the verification.const { status } = await ccd.verifyAddress(true, 12, 12);
Or
const { status } = await ccd.verifyAddress(false, 12, 12, 12);
