Cardano Transactions

Sign and submit Cardano transactions with explicit user confirmation.

Prerequisites

• @indigoprotocol/cardano-mcp server running

MCP Tools

• submit_transaction — Sign and submit a Cardano transaction CBOR

When to use

Use this skill when the user asks to:

• Submit or send a Cardano transaction
• Sign a transaction with their wallet
• Broadcast a pre-built transaction

Safety model

This tool is dangerous. Before calling submit_transaction:

1. Summarize the transaction in plain English.
2. Ask the user to explicitly confirm.
3. Only proceed if the user says yes.
4. Never submit a transaction automatically.

Data interpretation

• Input requires unsigned transaction CBOR (hex string).
• Output includes transactionHash and timestamp on success.
• The transaction is signed by the connected wallet's keys.
