Integration ​

The integration of the MWC revolves around two core workflows: Send and Receive. These workflows ensure smooth, privacy-focused, and efficient transactions.

Understanding the Interactive Process ​

MWC transactions are inherently interactive, requiring communication between the sender and the recipient. At its core, the sender creates an initial slate (a transaction template), shares it with the recipient, and waits for the recipient to respond with an updated slate. This updated slate is then finalized and broadcast to the blockchain by the sender.

Software Requirements ​

TIP

The MWC Python SDK supports both Wallet and Node APIs, including their respective Owner and Foreign APIs:

  • Wallet Owner API: Handles transaction creation, finalization, balance retrieval, and key management.
  • Wallet Foreign API: Facilitates receiving transactions and external interactions.
  • Node Owner API: Provides control over the node, including querying blockchain data.
  • Node Foreign API: Allows external interactions with the node for transaction broadcasting and retrieval.

Examples for Sender and Recipient workflows are in the /examples folder.

1. MWC Node Setup ​

  • Purpose: The MWC Node synchronizes with the blockchain and provides JSON-RPC APIs for interaction.

  • Resources:

  • Quick Start:

    • To run the node, simply execute:
      bash
      mwc

  • Listeners:

    • The node supports two APIs, both listening on localhost:3413:
      • Foreign API:
        • Available at: http://localhost:3413/v2/foreign.
        • Supports only POST operations, with the JSON-RPC request as the body.
        • Refer to the Foreign API Documentation for detailed usage.
        • Basic Authentification:
          • Username: mwcmain
          • Password: ~/.mwc/main/.foreign_api_secret
      • Owner API:
        • Available at: http://localhost:3413/v2/owner.
        • Supports only POST operations, with the JSON-RPC request as the body.
        • Refer to the Owner API Documentation for detailed usage.
        • Basic Authentification:
          • Username: mwcmain
          • Password: ~/.mwc/main/.api_secret

  • Critical Setup:

    • Ensure the node is fully synchronized with the blockchain before performing any transactions.

2. MWC Wallet Installation and Setup ​

  • Purpose: The MWC Wallet handles all transaction operations, including creating, receiving, and finalizing transaction slates.

  • Resources:

  • Quick Start:

    • Owner API:
      • Publicly accessible definition used to generate the Owner JSON-RPC API.
      • Start the Owner API by running:
        bash
        mwc-wallet owner_api
      • Available at: http://localhost:3420/v3/owner.
      • Supports only POST operations, with the JSON-RPC request as the body.
      • Refer to the Owner API Documentation for detailed usage.
      • Basic Authentification:
        • Username: mwc
        • Password: ~/.mwc/main/.owner_api_secret
    • Foreign API:
      • Publicly accessible definition used to generate the Foreign JSON-RPC API.
      • Start the Foreign API by running:
        bash
        mwc-wallet listen
      • Available at: http://localhost:3415/v2/foreign.
      • Supports only POST operations, with the JSON-RPC request as the body.
      • Refer to the Foreign API Documentation for detailed usage.

INFO

Ensure that the correct API mode is running based on your role in the transaction process.

  • Operational Modes:
    • If You Are the Sender: Use the Owner API to manage and send transactions.
    • If You Are the Recipient: Use the Foreign API to handle incoming transaction slates.

Sender Workflow ​

The Sender Workflow is responsible for initiating, encoding, and finalizing the transaction. For developers integrating MWC workflows, it's important to understand the interactive nature of the transaction process. Once you generate the initial Slatepack, you need to send it to the user (recipient) and wait for their response Slatepack to proceed further.

Here, we send the Slatepack to the recipient's address:

ENDSLATEPACK."
  }
}

Step 3: Sending the Initial Slatepack to the User ​

After creating and encoding the initial slate, you must share the slatepack with the recipient. Typically, this is done through a secure channel, such as a file, email, or a messaging service.

Example Slatepack to Share with the Recipient:

BEGINSLATEPACK. KbRGFBmJFBg5qWg k9Fi7EttkQKZ5pp L4mYHzzCfWw7Anf V8CZ6Ke1bkv3HxH XtrFoycTQ5FgC3p VZZpUiHVDXSXmKD wQJJHpKXZyqL66f bAs8CWvTPZoquaB Azd6XQVqeMRiape dmqpmhPUYE3f4Yr DQNLi9dzSPLU8c3 NT9frEz4oA2GaGB XsbFXqgsVgHeED5 f7859HKg8RVHQCn bC7dGVk3GnZKPA3 ejGahpUud7odiJi WJgThiYTwR7YdZg 9oyH21VCwoNMsar P1. ENDSLATEPACK.

Step 4: Waiting for the Recipient's Response ​

Once the recipient receives the initial slatepack, they will process it on their side using their wallet. After signing and updating the slate, the recipient will generate a response slatepack and send it back to you.

Example Response Slatepack:

Step 5: Finalize the Transaction ​

The sender finalizes the transaction by combining all signatures and preparing the transaction for broadcast using the finalize_tx method.

Step 6: Decode the Finalized Slate ​

Once the transaction is finalized, the next step is to decode the finalized Slatepack. Decoding reveals the transaction details necessary for broadcasting to the node and logging. The decoded slate includes critical information such as inputs, outputs, transaction kernels, and the offset value. Specifically, you need to extract the slate.tx object, which represents the finalized transaction. You can use the decode_slatepack_message method.

decode_slatepack_message POST

ParameterTypeDescription
tokenStringAPI token for authentication.
messageStringThe Slatepack message to be decoded.
address_indexIntegerOptional address index for receiving, defaults to null.

Step 7: Broadcast it to the node ​

Once the finalized slate has been decoded, extract the slate.tx object from the decoded slate. This object contains the transaction details, including inputs, outputs, kernels, and the offset. These details must be used as parameters in the broadcast request to the node.

The post_tx method is then called to broadcast the transaction. This step sends the finalized transaction to the node, allowing it to propagate across the MWC network. Ensure the tx parameter extracted from the decoded slate is correctly included in the request.

post_tx POST

ParameterTypeDescription
tokenStringAPI token for authentication.
txObjectThe transaction object extracted from the decoded slate.tx.
fluffBooleanWhether to propagate the transaction immediately (true) or allow the node to decide (false).

{"id": 1, "jsonrpc": "2.0", "result": {"Ok": null}}

If the response is Ok we can assume that the transactions was correctly built, sent to the node and correctly progated to the network.

Step 9: Track the Confirmation of the Transaction ​

Once the transaction is broadcasted to the MWC network, you will need to monitor the transaction's status to ensure the number of confirmation.

Request Example (Query Transaction Status):

Summary: Sender Workflow ​

The sender workflow for an MWC interactive transaction involves these key steps:

  1. Initiate Transaction: Begin creating the transaction.
  2. Encode Slatepack: Convert the transaction into a shareable slatepack.
  3. Send Initial Slatepack: Share the slatepack with the recipient.
  4. Wait for Recipient Response: Await the recipient's signed slatepack.
  5. Finalize the Transaction: Complete the transaction process.
  6. Decode the Finalized Slate: Interpret the finalized slate.
  7. Broadcast to the Network: Send the transaction to the network for propagation.
  8. Track Confirmation: Monitor the transaction until confirmed on the blockchain.

Recipient Workflow ​

The Recipient Workflow is responsible for receiving the initial transaction slate from the sender, processing it, and returning an updated slate to the sender. This interaction is critical for completing the MWC transaction process.

Step 1: Receive Transaction and Generate Response Slatepack ​

The recipient receives the initial Slatepack from the sender and processes it using the receive_tx method. This method updates the slate with the recipient's inputs and outputs.

Input Slatepack

The recipient receives the initial Slatepack from the sender. This Slatepack contains all the information needed to process the transaction.

Example Input Slatepack:

BEGINSLATE_BIN. 62GzuKRdyEXA7NS j9ZVB7tYCXotthS ZsjFZkRCmorDE1E LhTdCkxG1RP6A9U HaV64mMmLVcZur2 nyUiJGF4CcpwzGb qUy3uWgP2mp6H2p oXGd4w7GDYTubC2 1fkbtcpbThkSY9p Uw. ENDSLATE_BIN.

Optional: Decode the Slatepack ​

Before processing, the recipient can optionally decode the Slatepack to extract its content using the decode_slatepack_message method.
