@canton-network/core-signing-blockdaemon

This package provides a signing driver for integrating the Wallet Gateway with Blockdaemon. It implements the SigningDriverInterface defined in @canton-network/core-signing-lib, allowing the Wallet Gateway to manage keys and sign transactions using Blockdaemon's infrastructure.

Installation

This package is part of the Splice Wallet Kernel monorepo and is typically installed as a workspace dependency.

yarn add @canton-network/core-signing-blockdaemon

Usage

The BlockdaemonSigningDriver is designed to be used within the Wallet Gateway's signing architecture. It requires a configuration object containing the baseUrl and apiKey for the Blockdaemon service.

Initialization

import BlockdaemonSigningDriver, {
    BlockdaemonConfig,
} from '@canton-network/core-signing-blockdaemon'

const config: BlockdaemonConfig = {
    baseUrl: 'https://api.blockdaemon.com/...', // Replace with actual Blockdaemon API URL
    apiKey: 'your-api-key',
}

const driver = new BlockdaemonSigningDriver(config)

Features

The driver supports the following operations:

• Key Management:
  • createKey: Creates a new key pair on Blockdaemon.
  • getKeys: Retrieves a list of available keys.
• Signing:
  • signTransaction: Signs a transaction using a specified key.
• Transaction Monitoring:
  • getTransaction: Retrieves the status and details of a specific transaction.
  • getTransactions: Retrieves a list of transactions based on transaction IDs or public keys.
• Configuration:
  • getConfiguration: Returns the current configuration (masking sensitive secrets).
  • setConfiguration: Updates the driver's configuration at runtime.

Integration

This driver is intended to be registered with the SigningController in the Wallet Gateway, which manages multiple signing providers.

// Example integration (conceptual)
import { SigningController } from '@canton-network/core-signing-internal' // or similar

const signingController = new SigningController()
signingController.registerDriver(driver)

Configuration

The driver accepts a BlockdaemonConfig object:

Property	Type	Description
baseUrl	string	The base URL for the Blockdaemon Signing API.
apiKey	string	The API key for authentication.

Wallet Gateway Configuration

When running the Wallet Gateway (Remote), the Blockdaemon signing driver is configured using the following environment variables:

• BLOCKDAEMON_API_URL: The base URL for the Blockdaemon API. Defaults to http://localhost:5080/api/cwp/canton if not set.
• BLOCKDAEMON_API_KEY: The API key for authenticating with Blockdaemon.

Example usage:

BLOCKDAEMON_API_URL="https://api.blockdaemon.com/..." BLOCKDAEMON_API_KEY="your-api-key" yarn start
