# Cardano Wallet Skill for OpenClaw
**Generate, restore, and manage Cardano wallets with QR code funding support**
## Overview
The Cardano Wallet skill provides tools for AI agents to:
- Generate new Cardano wallets (24-word mnemonic)
- Restore wallets from existing mnemonics
- Generate QR codes for easy wallet funding
- Check wallet balances (requires Blockfrost API key)
- Securely backup wallet credentials
## Tools
### `cardano_generate_wallet`
Generate a new Cardano wallet with 24-word mnemonic phrase.
**Parameters:**
- `network` (optional): "Preprod" or "Mainnet" (default: "Preprod")
**Returns:**
- `address`: Cardano address (addr1...)
- `vkey`: Payment verification key
- `credentialsPath`: Path to encrypted credentials
**Example:**
```typescript
const wallet = await cardano_generate_wallet({ network: 'Preprod' });
console.log('Address:', wallet.address);
```
### `cardano_restore_wallet`
Restore a wallet from existing mnemonic phrase.
**Parameters:**
- `mnemonic` (required): 24-word mnemonic phrase
- `network` (optional): "Preprod" or "Mainnet"
- `agentIdentifier` (optional): Identifier to save credentials
**Example:**
```typescript
const wallet = await cardano_restore_wallet({
mnemonic: 'word1 word2 ... word24',
network: 'Preprod'
});
```
### `cardano_generate_funding_qr`
Generate QR code for wallet funding. Returns QR code as data URL.
**Parameters:**
- `address` (optional): Cardano address
- `agentIdentifier` (optional): Wallet identifier
- `network` (optional): "Preprod" or "Mainnet"
**Returns:**
- `qrDataUrl`: QR code as data URL (can be displayed in image)
- `address`: Wallet address
- `faucetUrl`: Preprod faucet URL (if Preprod network)
**Example:**
```typescript
const qr = await cardano_generate_funding_qr({
agentIdentifier: 'my-wallet',
network: 'Preprod'
});
// Display qr.qrDataUrl as image
```
### `cardano_get_wallet_balance`
Get wallet balance in ADA and lovelace. Requires Blockfrost API key.
**Parameters:**
- `agentIdentifier` (required): Wallet identifier
- `network` (optional): "Preprod" or "Mainnet"
- `blockfrostApiKey` (optional): Blockfrost API key (or use env var)
**Environment Variables:**
- `BLOCKFROST_API_KEY`: Blockfrost API key
- `BLOCKFROST_PREPROD_API_KEY`: Preprod API key
- `BLOCKFROST_MAINNET_API_KEY`: Mainnet API key
**Example:**
```typescript
const balance = await cardano_get_wallet_balance({
agentIdentifier: 'my-wallet',
network: 'Preprod'
});
console.log('Balance:', balance.ada, 'ADA');
```
### `cardano_backup_wallet`
Securely backup wallet credentials (encrypted).
**Parameters:**
- `agentIdentifier` (required): Wallet identifier
- `network` (optional): "Preprod" or "Mainnet"
**Returns:**
- `backupData`: Encrypted backup JSON
## Wallet Funding Workflow
1. **Generate wallet:**
```typescript
const wallet = await cardano_generate_wallet({ network: 'Preprod' });
```
2. **Generate QR code:**
```typescript
const qr = await cardano_generate_funding_qr({
address: wallet.address,
network: 'Preprod'
});
```
3. **Display QR code** (for human to scan and fund)
4. **For Preprod:** Use faucet at https://docs.cardano.org/cardano-testnet/tools/faucet
5. **Check balance:**
```typescript
const balance = await cardano_get_wallet_balance({
agentIdentifier: 'wallet-id',
network: 'Preprod',
blockfrostApiKey: 'your-api-key'
});
```
## Credential Storage
Credentials are stored encrypted at:
- `~/.openclaw/credentials/cardano-wallet/`
Files are encrypted with AES-256-GCM and have permissions 600 (owner read/write only).
## Security Notes
- **Never share your mnemonic** - it provides full access to your wallet
- **Backup your mnemonic securely** - use `cardano_backup_wallet` or save manually
- **Use Preprod for testing** - Mainnet uses real ADA
- **Encryption key**: Set `MASUMI_ENCRYPTION_KEY` environment variable for secure encryption
## Dependencies
- `@meshsdk/core`: Wallet operations
- `qrcode`: QR code generation
- `@blockfrost/blockfrost-js`: Balance queries (optional)
## Examples
See `examples/wallet-generation.ts` for complete examples.
