Enterprise Private Key Creation

Flexible Key Management

Enterprise Options: Organizations can leverage external enterprise wallet solutions (MetaMask Enterprise, hardware wallets) or utilize SettleMint's integrated key management for streamlined operations and enhanced security.

SettleMint's integrated signing proxy architecture captures eth_sendTransaction calls, applies appropriate enterprise security policies, and executes transactions with the designated private keys. This enterprise-grade infrastructure supports both direct JSON-RPC integration and development framework compatibility (Hardhat, Truffle) configured for remote signing operations.

Create a private key

Navigate to your application, click Private keys in the left navigation, and then click Create a private key. This opens a form.

Follow these steps to create the private key:

Choose a private key type:
- Accessible ECDSA P256: Standard Ethereum-style private keys with exposed mnemonic
- HD ECDSA P256: Hierarchical Deterministic keys for advanced key management
- HSM ECDSA P256: Hardware Security Module protected keys for maximum security
Choose a name for your private key
Select the nodes on which you want the key to be active
Click Confirm to create the key

# Create Accessible ECDSA P256 key
settlemint platform create private-key accessible-ecdsa-p256 my-key \
  --application my-app \
  --blockchain-node node-123

# Create HD ECDSA P256 key
settlemint platform create private-key hd-ecdsa-p256 my-key \
  --application my-app

# Create HSM ECDSA P256 key
settlemint platform create private-key hsm-ecdsa-p256 my-key \
  --application my-app

import { createSettleMintClient } from '@settlemint/sdk-js';

const client = createSettleMintClient({
  accessToken: 'your_access_token',
  instance: 'https://console.settlemint.com'
});

// Create private key
const createKey = async () => {
  const result = await client.privateKey.create({
    name: "my-key",
    applicationUniqueName: "my-app",
    privateKeyType: "ACCESSIBLE_ECDSA_P256", // or "HD_ECDSA_P256" or "HSM_ECDSA_P256"
    blockchainNodeUniqueNames: ["node-123"] // optional
  });
  console.log('Private key created:', result);
};

Manage private keys

Navigate to your application's Private keys section
Click on a private key to:
- View details and status
- Manage node associations
- Check balances
- Fund the key

# List all private keys
settlemint platform list private-keys --application <app-name>

# View specific key details
settlemint platform read private-key <private-key-unique-name>

# Restart a private key
settlemint platform restart private-key <private-key-unique-name>

// List private keys
const listKeys = async () => {
  const keys = await client.privateKey.list("your-app-name");
};

// Get key details
const getKey = async () => {
  const key = await client.privateKey.read("key-unique-name");
};

// Restart key
const restartKey = async () => {
  await client.privateKey.restart("key-unique-name");
};

Fund the private key

For networks that require gas to perform a transaction, your private key should contain enough funds to cover the gas price.

Click the private key in the overview to see detailed information
Open the Balances tab
Click Fund
Scan the QR code with your wallet/exchange to fund the key

Ensure your private key has sufficient funds before attempting transactions on networks that require gas fees.
