# 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.

# Transaction Concepts

## Transaction CBOR

Cardano transactions are serialized using CBOR (Concise Binary Object Representation). The MCP tool accepts an unsigned CBOR hex string, signs it with the wallet's keys, and submits it to the network.

## Signing

The wallet holds private keys derived from the seed phrase. Signing attaches a cryptographic witness proving the wallet owner authorized the transaction. The seed phrase is never exposed to the AI agent.

## Confirmation Flow

Transactions are irreversible once submitted and confirmed on-chain. Always follow the safety model:

1. Parse and explain what the transaction does.
2. Wait for explicit user confirmation.
3. Submit only after confirmation.

## Transaction Hash

After successful submission, the network returns a unique transaction hash (64-character hex). This can be used to look up the transaction on a Cardano explorer.

# Transaction MCP Tools Reference

## submit_transaction

Sign and submit a Cardano transaction from the connected wallet.

**Input:**

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `cbor` | `string` | Yes | Unsigned Cardano transaction in CBOR hex |

**Output:**

| Field | Type | Description |
|-------|------|-------------|
| `transactionHash` | `string` | Hash of the submitted transaction |
| `timestamp` | `number` | Millisecond timestamp of submission |

**Errors:** Returns an error message if signing or submission fails (e.g. insufficient funds, invalid CBOR).
