Overview

The Openfort Node.js SDK provides convenient access to the Openfort API for server-side applications. It enables developers to:

- Create and manage EVM and Solana backend wallets
- Sign messages, typed data, and transactions
- Execute gasless transactions with gas sponsorship policies
- Manage users, accounts, and transaction intents
- Integrate with smart contracts and token swaps

Installation

Requires Node.js 14 or higher.

``bash
npm install @openfort/openfort-node
`

`bash
yarn add @openfort/openfort-node
`

`bash
pnpm add @openfort/openfort-node
`

Quickstart

Get your API key from the Openfort Dashboard.

`typescript
import Openfort from "@openfort/openfort-node";

const openfort = new Openfort("sk_test_...", {
walletSecret: "your-wallet-secret", // Required for signing operations
});

// Create an EVM backend account
const account = await openfort.accounts.evm.backend.create({
name: "MyWallet",
});
console.log("Account address:", account.address);

// Sign a message (methods are on the account object)
const signature = await account.signMessage({
message: "Hello, Openfort!",
});
console.log("Signature:", signature);
`

Features

$3

Create and manage wallets across EVM chains and Solana:

`typescript
// EVM backend accounts
const evmAccount = await openfort.accounts.evm.backend.create({
name: "MyEVMWallet",
});

// Solana backend accounts
const solanaAccount = await openfort.accounts.solana.backend.create({
name: "MySolanaWallet",
});

// Import existing wallet
const imported = await openfort.accounts.evm.backend.import({
privateKey: "0x...",
name: "ImportedWallet",
});
`

$3

Sign messages, typed data, and transactions. Methods are called directly on the account object:

`typescript
// Sign message
const signature = await account.signMessage({
message: "Hello, Openfort!",
});

// Sign EIP-712 typed data
const typedSig = await account.signTypedData({
domain: { name: "MyApp", version: "1", chainId: 1 },
types: {
Person: [
{ name: "name", type: "string" },
{ name: "wallet", type: "address" },
],
},
primaryType: "Person",
message: { name: "Alice", wallet: "0x..." },
});
`

$3

Sponsor gas fees for your users with policies:

`typescript
// Create a sponsorship policy
const policy = await openfort.policies.create({
name: "Free gas for users",
chainId: 80002,
strategy: { sponsorSchema: "pay_for_user" },
});

// Register a contract
const contract = await openfort.contracts.create({
name: "MyContract",
chainId: 80002,
address: "0x38090d1636069c0ff1af6bc1737fb996b7f63ac0",
});

// Add rules to control sponsorship
await openfort.policyRules.create({
policy: policy.id,
type: "account_functions",
contract: contract.id,
functionName: "mint",
});
`

$3

Manage users and verify sessions:

`typescript
// List authenticated users
const users = await openfort.iam.users.list({ limit: 10 });

// Verify session from access token
const session = await openfort.iam.getSession({ accessToken });
console.log("User ID:", session.user.id);
console.log("Session expires:", session.session.expiresAt);
`
