Cardano Mendix Plugin by Landano

Overview

The Cardano Mendix Plugin is a powerful bridge between the Mendix low-code platform and the Cardano blockchain. Developed by Landano, this plugin empowers Mendix developers to build decentralized applications (dApps) that support Cardano-native features like wallet creation, ADA transactions, NFT minting, metadata attachment, and smart contract interaction — all without leaving the Mendix ecosystem.

The plugin is fully open-source and packaged as a set of Mendix modules with Java and JavaScript actions. It supports both custodial and browser-based wallets and uses Blockfrost as its backend.

Prerequisites

To get started, you’ll need:

• Mendix Studio Pro 10.x
• Java 11+
• A Blockfrost API key (for testnet or mainnet)

Usage

The fastest way to explore the plugin is to open the example project included in this repository. It includes a fully functional UI and prebuilt flows.

Wallet Management

You can:

• Create a new wallet with a secure passphrase and generated mnemonic
• Restore an existing wallet using a 15-word phrase

All mnemonics are encrypted in the Mendix database using a passphrase + key setup.

Transaction Workflow

The transaction process is broken into 4 user-friendly steps:

1. Choose type:

   • Simple ADA transaction
   • Metadata transaction
   • NFT minting
   • Multi-sig
   • Smart contract lock/unlock

2. Enter transaction details

3. Verify the transaction

4. Confirm and submit with passphrase

NFT Minting

The plugin supports:

• One-click NFT minting with a metadata form
• Optional IPFS image or metadata pinning using the PinataIPFS module

Browser Wallets (Web Only)

You can connect to wallets like Lace or Eternl in the browser using:

• JS_Wallet_Connect
• JS_GetUsedCardanoWalletAddresses
• JS_GetCardanoWalletRewardAddresses

The Landano team thanks the Bloxbean team for their support. Without the cardano-client-lib we wouldn't have been able to build the Cardano Mendix Plugin.
