# Zyfai — Yield for Any Wallet

Let any Ethereum wallet access a yield-generating account.

## What This Does

When a user wants to **earn yield** on their crypto, Zyfai creates a **deterministic subaccount** (Safe smart wallet) linked to their existing wallet (EOA). Funds deposited into this subaccount are automatically optimized across DeFi protocols. The user stays in full control and can withdraw anytime.

```
┌─────────────────┐      ┌──────────────────────┐
│   User's EOA    │ ───► │  Zyfai Subaccount    │
│  (their wallet) │      │  (Safe smart wallet) │
│                 │      │                      │
│  Owns & controls│      │  • Auto-rebalancing  │
│                 │      │  • Yield optimization│
│                 │      │  • Non-custodial     │
└─────────────────┘      └──────────────────────┘
```

**Key points:**
- The subaccount is **owned by the user's EOA** — only they can withdraw
- Session keys allow **automated rebalancing** but cannot withdraw to other addresses
- Same EOA = same subaccount address across all chains

## The Flow

```
1. DEPLOY    →  Create a deterministic subaccount linked to user's wallet
2. SESSION   →  Enable automated yield optimization  
3. DEPOSIT   →  Send funds to subaccount (starts earning)
4. WITHDRAW  →  Pull funds back to wallet (anytime)
```

## Prerequisites

- **API Key** — Get one programmatically (see below) or manually at [sdk.zyf.ai](https://sdk.zyf.ai)
- **Wallet Connection** — Either a wallet provider (browser) or secure key management (server)
- **Node.js 18+**

```bash
npm install @zyfai/sdk viem
```

### Programmatic API Key Creation (Agent-Native)

Agents can create their own API key without human intervention. You need the wallet address (public key) of the agent.

```bash
POST https://sdk.zyf.ai/api/sdk-api-keys/create
Content-Type: application/json

{
  "clientName": "my-agent",
  "walletAddress": "0x...",
  "email": "agent@example.com"
}
```

**Response:**
```json
{
  "success": true,
  "message": "SDK API key created successfully. Store the apiKey securely - it cannot be retrieved later!",
  "data": {
    "id": "936...",
    "apiKey": "zyfai_361ad41d083c2fe.....",
    "keyPrefix": "zyfai_361ad4",
    "clientName": "my-agent",
    "ownerWalletAddress": "0x..."
  }
}
```

> **Important:** Store the `apiKey` securely — it cannot be retrieved later. The key is linked to the provided wallet address.

## Supported Chains

| Chain    | ID    |
|----------|-------|
| Arbitrum | 42161 |
| Base     | 8453  |
| Plasma   | 9745  |

## Important: Always Use EOA Address

When calling SDK methods, **always pass the EOA address** (the user's wallet address) as `userAddress` — never the subaccount/Safe address. The SDK derives the subaccount address automatically from the EOA.

## Wallet Connection Options

The SDK supports multiple ways to connect a wallet. Choose based on your security requirements and deployment context.

### Option 1: Wallet Provider (Recommended for Browser/dApps)

Use an injected wallet provider like MetaMask. The private key never leaves the user's wallet.

```typescript
import { ZyfaiSDK } from "@zyfai/sdk";

const sdk = new ZyfaiSDK({ apiKey: "your-api-key", referralSource: "openclaw-skill" });

// Connect using injected wallet provider (MetaMask, WalletConnect, etc.)
await sdk.connectAccount(window.ethereum, 8453);
```

**Security:** The private key stays in the user's wallet. The SDK only requests signatures when needed.

### Option 2: Viem WalletClient (Recommended for Server Agents)

Use a pre-configured viem WalletClient. This is the recommended approach for server-side agents as it allows integration with secure key management solutions.

```typescript
import { ZyfaiSDK } from "@zyfai/sdk";
import { createWalletClient, http } from "viem";
import { base } from "viem/chains";
import { privateKeyToAccount } from "viem/accounts";

// Create wallet client with your preferred key management
// Option A: From environment variable (simple but requires secure env management)
const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`);

// Option B: From KMS (AWS, GCP, etc.) - recommended for production
// const account = await getAccountFromKMS();

// Option C: From Wallet-as-a-Service (Turnkey, Privy, etc.)
// const account = await turnkeyClient.getAccount();

const walletClient = createWalletClient({
  account,
  chain: base,
  transport: http(),
});

const sdk = new ZyfaiSDK({ apiKey: "your-api-key", referralSource: "openclaw-skill" });

// Connect using the WalletClient
await sdk.connectAccount(walletClient, 8453);
```

**Security:** The WalletClient abstraction allows you to integrate with secure key management solutions like:
- **AWS KMS** / **GCP Cloud KMS** — Hardware-backed key storage
- **Turnkey** / **Privy** / **Dynamic** — Wallet-as-a-Service providers
- **Hardware wallets** — Via WalletConnect or similar

### Option 3: Private Key String (Development Only)

Direct private key usage.

```typescript
import { ZyfaiSDK } from "@zyfai/sdk";

const sdk = new ZyfaiSDK({ apiKey: "your-api-key", referralSource: "openclaw-skill" });

// WARNING: Only use for development. Never hardcode private keys in production.
await sdk.connectAccount(process.env.PRIVATE_KEY, 8453);
```

**Security Warning:** Raw private keys in environment variables are a security risk. For production autonomous agents, use Option 2 with a proper key management solution.

### Security Comparison

| Method | Security Level | Use Case |
|--------|---------------|----------|
| Wallet Provider | High | Browser dApps, user-facing apps |
| WalletClient + KMS | High | Production server agents |
| WalletClient + WaaS | High | Production server agents |
| Private Key String | Low | Development/testing only |

## Step-by-Step

### 1. Connect to Zyfai

```typescript
import { ZyfaiSDK } from "@zyfai/sdk";
import { createWalletClient, http } from "viem";
import { base } from "viem/chains";
import { privateKeyToAccount } from "viem/accounts";

const sdk = new ZyfaiSDK({ apiKey: "your-api-key", referralSource: "openclaw-skill" });

// For browser: use wallet provider
await sdk.connectAccount(window.ethereum, 8453);

// For server: use WalletClient (see Wallet Connection Options above)
const walletClient = createWalletClient({
  account: privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`),
  chain: base,
  transport: http(),
});
await sdk.connectAccount(walletClient, 8453);
```

### 2. Deploy Subaccount

```typescript
const userAddress = "0x..."; // User's EOA (NOT the subaccount address!)
const chainId = 8453; // Base

// Check if subaccount exists
const wallet = await sdk.getSmartWalletAddress(userAddress, chainId);
console.log(`Subaccount: ${wallet.address}`);
console.log(`Deployed: ${wallet.isDeployed}`);

// Deploy if needed
if (!wallet.isDeployed) {
  const result = await sdk.deploySafe(userAddress, chainId, "conservative");
  console.log("Subaccount deployed:", result.safeAddress);
}
```

**Strategies:**
- `"conservative"` — Stable yield, lower risk
- `"aggressive"` — Higher yield, higher risk

### 3. Enable Yield Optimization

```typescript
await sdk.createSessionKey(userAddress, chainId);

// Always verify the session key was activated
const user = await sdk.getUserDetails();
if (!user.user.hasActiveSessionKey) {
  // Session key not active — retry the process
  console.log("Session key not active, retrying...");
  await sdk.createSessionKey(userAddress, chainId);
  
  // Verify again
  const userRetry = await sdk.getUserDetails();
  if (!userRetry.user.hasActiveSessionKey) {
    throw new Error("Session key activation failed after retry. Contact support.");
  }
}
console.log("Session key active:", user.user.hasActiveSessionKey);
```

This allows Zyfai to rebalance funds automatically. Session keys **cannot** withdraw to arbitrary addresses — only optimize within the protocol.

> **Important:** Always verify the session key is active by checking `getUserDetails().user.hasActiveSessionKey` after calling `createSessionKey`. If it returns `false`, retry the process. A session key must be active for automated yield optimization to work.

### 4. Deposit Funds

```typescript
// Deposit 10 USDC (6 decimals)
await sdk.depositFunds(userAddress, chainId, "10000000");
```

Funds move from EOA -> Subaccount and start earning yield immediately.

### 5. Withdraw Funds

```typescript
// Withdraw everything
await sdk.withdrawFunds(userAddress, chainId);

// Or withdraw partial (5 USDC)
await sdk.withdrawFunds(userAddress, chainId, "5000000");
```

Funds return to the user's EOA. Withdrawals are processed asynchronously.

### 6. Disconnect

```typescript
await sdk.disconnectAccount();
```

## Complete Example

```typescript
import { ZyfaiSDK } from "@zyfai/sdk";
import { createWalletClient, http } from "viem";
import { base } from "viem/chains";
import { privateKeyToAccount } from "viem/accounts";

async function startEarningYield(userAddress: string) {
  const sdk = new ZyfaiSDK({ apiKey: process.env.ZYFAI_API_KEY! });
  const chainId = 8453; // Base
  
  // Connect using WalletClient (recommended for server agents)
  const walletClient = createWalletClient({
    account: privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`),
    chain: base,
    transport: http(),
  });
  await sdk.connectAccount(walletClient, chainId);
  
  // Deploy subaccount if needed (always pass EOA as userAddress)
  const wallet = await sdk.getSmartWalletAddress(userAddress, chainId);
  if (!wallet.isDeployed) {
    await sdk.deploySafe(userAddress, chainId, "conservative");
    console.log("Subaccount created:", wallet.address);
  }
  
  // Enable automated optimization
  await sdk.createSessionKey(userAddress, chainId);
  
  // Verify session key is active
  const user = await sdk.getUserDetails();
  if (!user.user.hasActiveSessionKey) {
    console.log("Session key not active, retrying...");
    await sdk.createSessionKey(userAddress, chainId);
    const userRetry = await sdk.getUserDetails();
    if (!userRetry.user.hasActiveSessionKey) {
      throw new Error("Session key activation failed. Contact support.");
    }
  }
  
  // Deposit 100 USDC
  await sdk.depositFunds(userAddress, chainId, "100000000");
  console.log("Deposited! Now earning yield.");
  
  await sdk.disconnectAccount();
}

async function withdrawYield(userAddress: string, amount?: string) {
  const sdk = new ZyfaiSDK({ apiKey: process.env.ZYFAI_API_KEY! });
  const chainId = 8453; // Base
  
  // Connect using WalletClient
  const walletClient = createWalletClient({
    account: privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`),
    chain: base,
    transport: http(),
  });
  await sdk.connectAccount(walletClient, chainId);
  
  // Withdraw funds (pass EOA as userAddress)
  if (amount) {
    // Partial withdrawal
    await sdk.withdrawFunds(userAddress, chainId, amount);
    console.log(`Withdrawn ${amount} (6 decimals) to EOA`);
  } else {
    // Full withdrawal
    await sdk.withdrawFunds(userAddress, chainId);
    console.log("Withdrawn all funds to EOA");
  }
  
  await sdk.disconnectAccount();
}
```

interface UserDetailsResponse {
  success: boolean;
  user: {
    id: string;
    address: string;
    smartWallet?: string;
    chains: number[];
    protocols: Protocol[];
    hasActiveSessionKey: boolean;
    email?: string;
    strategy?: string;
    telegramId?: string;
    walletType?: string;
    autoSelectProtocols: boolean;
    autocompounding?: boolean;
    omniAccount?: boolean;
    crosschainStrategy?: boolean;
    agentName?: string;
    customization?: Record<string, string[]>;
  };
}
```

### updateUserProfile

Update the authenticated user's profile settings including strategy, protocols, splitting, and cross-chain options. Requires SIWE authentication.

```typescript
sdk.updateUserProfile(params: UpdateUserProfileRequest): Promise<UpdateUserProfileResponse>
```

**Parameters:**

```typescript
interface UpdateUserProfileRequest {
  /** Investment strategy: "conservative" for safer yields, "aggressive" for higher risk/reward */
  strategy?: "conservative" | "aggressive";

  /** Array of protocol IDs to use for yield optimization */
  protocols?: string[];

  /** Enable omni-account feature for cross-chain operations */
  omniAccount?: boolean;

  /** Enable automatic compounding of earned yields (default: true) */
  autocompounding?: boolean;

  /** Custom name for your agent */
  agentName?: string;

  /** Enable cross-chain strategy execution */
  crosschainStrategy?: boolean;

  /** Enable position splitting across multiple protocols */
  splitting?: boolean;

  /** Minimum number of splits when position splitting is enabled (1-4) */
  minSplits?: number;
}
```

**Returns:**

```typescript
interface UpdateUserProfileResponse {
  success: boolean;
  userId: string;
  smartWallet?: string;
  chains?: number[];
  strategy?: string;
  protocols?: string[];
  omniAccount?: boolean;
  autocompounding?: boolean;
  agentName?: string;
  crosschainStrategy?: boolean;
  executorProxy?: boolean;
  splitting?: boolean;
  minSplits?: number;
}
```

**Examples:**

```typescript
// Update strategy from conservative to aggressive
await sdk.updateUserProfile({
  strategy: "aggressive",
});

// Configure specific protocols
const protocolsResponse = await sdk.getAvailableProtocols(8453);
const selectedProtocols = protocolsResponse.protocols
  .filter(p => ["Aave", "Compound", "Moonwell"].includes(p.name))
  .map(p => p.id);

await sdk.updateUserProfile({
  protocols: selectedProtocols,
});

// Enable position splitting (distribute across multiple protocols)
await sdk.updateUserProfile({
  splitting: true,
  minSplits: 3, // Split across at least 3 protocols
});

// Verify changes
const userDetails = await sdk.getUserDetails();
console.log("Strategy:", userDetails.user.strategy);
console.log("Splitting:", userDetails.user.splitting);
```

> **Cross-chain strategies:** Only enable cross-chain when the user **explicitly requests** it. For cross-chain to work, **both** `crosschainStrategy` and `omniAccount` must be set to `true`. Never enable cross-chain settings by default.

```typescript
// Enable cross-chain ONLY when explicitly requested by the user
await sdk.updateUserProfile({
  crosschainStrategy: true,
  omniAccount: true,
});

// Now funds can be rebalanced across configured chains
const user = await sdk.getUserDetails();
console.log("Operating on chains:", user.user.chains);
```

**Notes:**
- **Strategy:** Can be changed anytime. Subsequent rebalancing uses the new active strategy.
- **Protocols:** Use `getAvailableProtocols(chainId)` to get valid protocol IDs before updating.
- **Smart Splitting (minSplits = 1):** Default mode. To maximize returns, funds are automatically distributed across multiple DeFi pools — but only when beneficial. The system intelligently decides when splitting is advantageous based on current market conditions and opportunities. Funds may not split if no opportunity exists.
- **Forced Splitting (minSplits > 1):** When `minSplits` is set to 2, 3, or 4, funds are always distributed across at least that many pools for improved risk diversification (up to 4 DeFi pools). This guarantees your funds will be split regardless of market conditions.
- **Cross-chain:** Requires **both** `crosschainStrategy: true` AND `omniAccount: true`. Only activate when the user explicitly asks for cross-chain yield optimization. Chains are configured during initial setup and cannot be changed via this method.
- **Auto-compounding:** Enabled by default. When `true`, yields are reinvested automatically.
- Smart wallet address, chains, and `executorProxy` cannot be updated via this method.

### getAPYPerStrategy

Get global APY by strategy type (conservative or aggressive), time period, and chain configuration. Use this to compare expected returns between strategies before deploying.

**Parameters:**

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| crossChain | boolean | No | If `true`, returns APY for cross-chain strategies; if `false`, single-chain |
| days | number | No | Period over which APY is calculated. One of `7`, `15`, `30`, `60` |
| strategyType | string | No | Strategy risk profile. One of `'conservative'` or `'aggressive'` |

**Example:**

```typescript
// Get 7-day APY for conservative single-chain strategy
const conservativeApy = await sdk.getAPYPerStrategy(false, 7, 'conservative');
console.log("Conservative APY:", conservativeApy.data);

// Get 30-day APY for aggressive cross-chain strategy
const aggressiveApy = await sdk.getAPYPerStrategy(true, 30, 'aggressive');
console.log("Aggressive APY:", aggressiveApy.data);

// Compare strategies
const conservative = await sdk.getAPYPerStrategy(false, 30, 'conservative');
const aggressive = await sdk.getAPYPerStrategy(false, 30, 'aggressive');
console.log(`Conservative 30d APY: ${conservative.data[0]?.apy}%`);
console.log(`Aggressive 30d APY: ${aggressive.data[0]?.apy}%`);
```

**Returns:**

```typescript
interface APYPerStrategyResponse {
  success: boolean;
  count: number;
  data: APYPerStrategy[];
}

interface APYPerStrategy {
  strategyType: string;
  apy: number;
  period: number;
  crossChain: boolean;
}
```

### getOnchainEarnings

Get onchain earnings for a wallet including total, current, and lifetime earnings.

```typescript
const earnings = await sdk.getOnchainEarnings(smartWalletAddress);

console.log("Total earnings:", earnings.data.totalEarnings);
console.log("Current earnings:", earnings.data.currentEarnings);
console.log("Lifetime earnings:", earnings.data.lifetimeEarnings);
```

Returns:
```typescript
interface OnchainEarningsResponse {
  success: boolean;
  data: {
    walletAddress: string;
    totalEarnings: number;
    currentEarnings: number;
    lifetimeEarnings: number;
    unrealizedEarnings?: number;
    currentEarningsByChain?: Record<string, number>;
    unrealizedEarningsByChain?: Record<string, number>;
    lastCheckTimestamp?: string;
  };
}
```

### registerAgentOnIdentityRegistry (ERC-8004)

Register your Zyfai deployed agent on the Identity Registry following the ERC-8004 standard. This is used for OpenClaw agent registration. The method fetches a tokenUri containing the agent's metadata stored on IPFS, then registers it on-chain.

**Supported Chains:**

| Chain | Chain ID |
|-------|----------|
| Base | 8453 |
| Arbitrum | 42161 |

**Parameters:**

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| smartWallet | string | Yes | The Zyfai deployed smart wallet address to register as an agent |
| chainId | SupportedChainId | Yes | Chain ID (only 8453 or 42161) |

**Example:**

```typescript
const sdk = new ZyfaiSDK({ apiKey: "your-api-key" });
await sdk.connectAccount(walletClient, 8453);

// Get smart wallet address
const walletInfo = await sdk.getSmartWalletAddress(userAddress, 8453);
const smartWallet = walletInfo.address;

// Register agent on Identity Registry
const result = await sdk.registerAgentOnIdentityRegistry(smartWallet, 8453);

console.log("Registration successful:");
console.log("  Tx Hash:", result.txHash);
console.log("  Chain ID:", result.chainId);
console.log("  Smart Wallet:", result.smartWallet);
```

**Returns:**

```typescript
interface RegisterAgentResponse {
  success: boolean;
  txHash: string;
  chainId: number;
  smartWallet: string;
}
```

**How It Works:**

1. Fetches a `tokenUri` from the Zyfai API (agent metadata stored on IPFS)
2. Encodes the `register(tokenUri)` call for the Identity Registry contract
3. Sends the transaction from the connected wallet
4. Waits for on-chain confirmation

## Security

- **Non-custodial** — User's EOA owns the subaccount
- **Session keys are limited** — Can rebalance, cannot withdraw elsewhere
- **Deterministic** — Same EOA = same subaccount on every chain
- **Flexible key management** — Use wallet providers, WalletClients, or KMS integrations

### Key Management Best Practices

For **production autonomous agents**, we recommend:

1. **Use a WalletClient** with a secure key source (not raw private keys)
2. **Integrate with KMS** (AWS KMS, GCP Cloud KMS) for hardware-backed key storage
3. **Consider Wallet-as-a-Service** providers like Turnkey, Privy, or Dynamic
4. **Never hardcode** private keys in source code
5. **Rotate keys** periodically and implement key revocation procedures

## Troubleshooting

### Subaccount address mismatch across chains

The subaccount address should be **identical** across all chains for the same EOA. If you see different addresses:

```typescript
// Check addresses on both chains
const baseWallet = await sdk.getSmartWalletAddress(userAddress, 8453);
const arbWallet = await sdk.getSmartWalletAddress(userAddress, 42161);

if (baseWallet.address !== arbWallet.address) {
  console.error("Address mismatch! Contact support.");
}
```

**If addresses don't match:**
1. Try redeploying on the affected chain
2. If the issue persists, contact support on Telegram: [@paul_zyfai](https://t.me/paul_zyfai)

### "Deposit address not found" error

This means the wallet isn't registered in the backend. Solution:
1. Call `deploySafe()` first — even if the Safe is already deployed on-chain, this registers it with the backend
2. Then retry `createSessionKey()`

### "Invalid signature" error

This typically means:
- The wallet/signer doesn't match the EOA you're passing
- The Safe address on-chain doesn't match what the SDK expects

Verify you're using the correct wallet for the EOA.
