Understanding Your Deposit

Phase 1: Setup (One-Time)

Step 1: Connect Your Wallet

Two ways to connect:

Option A: Social Login (Recommended for Beginners)

• Sign in with Google, Apple, or email
• Creates an embedded wallet automatically
• Gas fees sponsored for initial transactions
• No browser extension needed

Option B: EOA Wallet (For Experienced Users)

• Connect MetaMask, WalletConnect, or other Web3 wallets
• Use your existing wallet and addresses
• You manage your own gas fees
• Full control over private keys

What happens next:

• SynthOS creates a smart wallet for you on Scroll
• This smart wallet will hold your vault and execute transactions
• Your login wallet is just for signing - funds live in the smart wallet

Step 2: AI Analyzes Your Activity

Once connected, the AI immediately begins analyzing:

What it scans:

• Last 30-90 days of transaction history
• Protocols you've interacted with (Aave, Uniswap, etc.)
• Types of strategies you've used (lending, LP, staking)
• Average position sizes and hold durations
• Chains you're most active on

Analysis time: 2-3 minutes for comprehensive profile

Your DeFi Profile includes:

• Experience Level: Beginner, Intermediate, or Advanced
• Risk Tolerance: Conservative, Balanced, or Aggressive
• Preferred Chains: Which networks you use most
• Strategy Preferences: Lending, liquidity provision, staking, etc.

New wallet? If you have no DeFi history, AI defaults to conservative recommendations. As you use SynthOS, it learns your preferences.

Step 3: Create Your Personal Vault

What is a vault? When you create a User Vault, you're not making a new wallet - you're creating a personal smart contract that SynthOS uses to manage your yield strategies.

Why you need a vault:

• Your wallet can't track strategies or manage cross-chain deposits
• The vault keeps all your positions in one place
• It updates automatically when deposits/withdrawals complete
• It can be upgraded over time without affecting your wallet

Key properties:

• One vault per user on Scroll (your "home base")
• Non-custodial: Only you control deposits/withdrawals
• Beacon proxy pattern: Gas-efficient upgrades without changing your address
• Cross-chain tracking: Monitors positions on Arbitrum, Base, Optimism, etc.

Gas cost: ~$0.05-0.10 on Scroll (one-time fee)

Phase 2: Depositing & Allocating

Step 4: Deposit Base Assets to Your Vault

What to deposit:

• USDC: Main asset for yield strategies
• ETH: For gas fees on transactions

How much ETH?

• Minimum: ~$5 worth for gas fees
• Recommended: ~$10-20 for multiple transactions
• ETH stays in your smart wallet for gas, not in the vault

How much USDC?

• Minimum varies by strategy (typically $10-100)
• Start small to test the system
• You can deposit more anytime

Deposit methods:

• From your EOA wallet: Transfer from MetaMask or other wallet
• From another chain: Bridge from Arbitrum, Base, etc.
• Swap from other tokens: Convert ETH, USDT, etc. to USDC

Important: Assets deposited to your vault are idle (earning 0% yield) until you allocate them to strategies. Think of your vault as a staging area.

Step 5: View AI-Recommended Strategies

After depositing, the AI shows you personalized yield opportunities:

What you'll see:

• Yield Bundles: Diversified portfolios of multiple strategies
• Single Strategies: Individual yield opportunities
• Risk levels: Stable, Balanced, or Growth
• Current APY: Updated hourly
• Protocol details: Aave, Morpho, Compound, etc.
• Target chain: Where the yield is generated

Filter options:

• By risk level (Stable/Balanced/Growth)
• By protocol (Aave, Morpho, etc.)
• By chain (Arbitrum, Base, Optimism)
• AI Recommended only

Step 6: Choose a Strategy

Option A: Invest in a Yield Bundle

What is a bundle? A curated portfolio of multiple strategies grouped by risk level:

• Stable Bundle: 3-5 low-risk strategies (blue-chip protocols)
• Balanced Bundle: Mix of established and newer protocols
• Growth Bundle: Higher-risk, higher-reward opportunities

Benefits:

• Instant diversification across protocols
• Reduced risk compared to single strategies
• AI-optimized allocation within bundle
• One-click deployment

Option B: Invest in Single Strategies

When to choose single strategies:

• You want full control over allocation
• You have strong conviction in specific protocols
• You're building a custom portfolio
• You want to avoid certain chains or protocols

Strategy details:

Each strategy shows:

• Current APY and historical chart
• Protocol name and audit status
• Total Value Locked (TVL)
• Your potential earnings calculator
• Risk rating (A+ to D)
• Minimum deposit amount

Step 7: Allocate Funds

Enter allocation amount:

• Must meet strategy minimum (varies by protocol)

Once confirmed, click "Allocate" to complete the transaction.

Phase 3: Cross-Chain Operations (The Important Part)

Understanding Cross-Chain Deposits

When you allocate to a strategy on another chain (e.g., Aave on Arbitrum), here's what happens:

Step-by-Step Process

1. You initiate (0 seconds)

• Click "Allocate" on the frontend
• Approve transaction in your wallet
• Transaction submitted to Scroll

2. Smart contract sends (10-30 seconds)

• Your USDC leaves your vault on Scroll
• LayerZero bridge message created
• Transaction confirmed on Scroll

3. Pending state (2-5 minutes)

• Your allocation shows as "Processing"
• LayerZero relays message across chains
• You can track progress via LayerZero Scan link

4. Bridge completes (varies by chain)

• Your USDC arrives on destination chain (e.g., Arbitrum)
• Destination vault receives your deposit
• You receive receipt tokens (e.g., aUSDC)

5. Validator confirms (0-60 seconds)

• Our validator detects bridge completion
• Calls your vault to update position
• Validator runs every 60 seconds

6. Position created (instant)

• Your position shows as "Active"
• You now hold receipt tokens tracked in your vault
• Yield begins accruing immediately

What You See During Processing

Pending operation card shows:

• Destination strategy and chain
• Amount deposited
• Estimated completion time (2-5 minutes)
• Current status (Processing → Confirming → Completed)
• LayerZero Scan link for real-time tracking
• Message GUID (for support if needed)

After 40-60 seconds: The validator confirms your deposit and your position becomes active.

Why the Wait?

Cross-chain operations need confirmation from the destination chain.

Without validator confirmation:

• Your vault wouldn't know if bridge succeeded
• You might see a position that doesn't actually exist
• Failed bridges wouldn't trigger refunds

With validator confirmation:

• Your vault only shows real, confirmed positions
• Failed bridges automatically refund to your vault
• You can trust your displayed balance

Same-Chain Deposits (Instant)

If you allocate to a strategy on Scroll (same chain as your vault):

• No bridging needed
• Instant confirmation
• Position active immediately
• Lower gas fees

Troubleshooting Your Journey

"My deposit is stuck in Processing"

Check:

1. Click LayerZero Scan link in pending operation
2. Verify message status (INFLIGHT, DELIVERED, FAILED)
3. If DELIVERED, wait for next validator cycle (60 seconds)
4. If FAILED, refund triggers automatically

Timeline:

• Normal: 2-5 minutes
• Congested network: 5-15 minutes
• If stuck >20 minutes: Contact support with message GUID

"I can't withdraw from a position"

Possible causes:

• Position is still "Processing" (wait for Active status)
• Insufficient liquidity in destination protocol (rare)
• You already have a pending withdrawal

Fix:

• Wait for position to become Active
• Try partial withdrawal instead of full
• Check "Pending Operations" for existing withdrawal
