cardano-transactions

What This Skill Does

The Cardano Transactions skill provides a secure interface for interacting with the Cardano blockchain directly from the OpenClaw AI agent. It allows users to sign and submit pre-built transaction CBOR strings using their connected wallet keys. By leveraging the @indigoprotocol/cardano-mcp server, this skill acts as a bridge between the agent's logic and the user's blockchain assets. The core functionality centers on the submit_transaction tool, which ensures that complex blockchain operations are handled with precision while maintaining the user's absolute control over their private keys and assets.

Installation

To integrate this skill into your OpenClaw environment, ensure you have the required MCP server dependency installed and configured. Then, run the following command in your terminal:

clawhub install openclaw/skills/skills/adacapo21/cardano-transactions

Ensure your wallet software is active and the MCP server is communicating properly with your local node or wallet provider before invoking the tool.

Use Cases

This skill is designed for scenarios where automated or semi-automated interaction with the Cardano network is required. It is ideal for:

• Executing smart contract interactions that have been pre-compiled into CBOR.
• Submitting cross-chain bridge transactions after a bridging request has been finalized.
• Handling batch transactions for NFT minting or distribution.
• Finalizing decentralized finance (DeFi) swaps initiated through OpenClaw workflows.

Example Prompts

1. "I have this transaction hex string: [CBOR_HEX_HERE]. Please sign and submit this to the Cardano network for me."
2. "Can you process the transaction I just generated for the Indigo Protocol? Here is the CBOR: [CBOR_HEX_HERE]."
3. "I need to broadcast my pending ADA transaction. I have the signed CBOR ready to go, please submit it."

Tips & Limitations

This tool is powerful but demands high vigilance. Always inspect the transaction summary provided by the agent before confirming. The tool only accepts hex-encoded CBOR; ensure your transaction builder outputs compatible formats. Because this involves real-world assets, the safety model enforces a hard stop: the agent will refuse to submit any transaction without an explicit, unambiguous confirmation from the user. If the transaction fails, double-check that your wallet is unlocked and that the network protocol version matches the transaction requirements.
