Pre-funding

Pre-Funding: Leverage Multiplication Engine

Core Mechanism

Pre-funding enables traders to amplify their buying power through a collateral-backed loan system that operates before position opening:

Mathematical Foundation

Leverage Calculation:

Effective Leverage = (Borrowed Amount + Self-Capital) × Exchange Leverage ÷ Self-Capital
                   = ($4,000 + $1,000) × 40x ÷ $1,000 
                   = 200,000 ÷ 1,000 
                   = 200x

Note: Combined with position size, actual effective leverage = 200x

Loss Containment Formula:

Max Protocol Loss = 0
Max Trader Loss = 100% of Self-Capital
Loan Protection Buffer = Position Size × (1 - β) > Borrowed Amount

Key Components

Component	Function	Protection Mechanism
Capital Multiplier	Amplifies trader collateral	4:1 debt-to-collateral ratio
Dynamic Stop-Loss	Prevents loan impairment	Real-time β-adjusted liquidation threshold
Auto-Repayment	Secures lender capital	Direct principal return on liquidation
Interest Escrow	Protects lender yield	Deducted before profit distribution

Risk Control Workflow

Performance Advantages

1. Leverage Amplification Turns 40x exchange leverage → 200x effective exposure

2. Capital Protection Guarantees 100% principal recovery for Fund Vault

3. Zero Slippage Entry Pre-funded collateral enables instant position opening

4. Interest Rate Efficiency Loans priced at competitive rates:

   Base Rate: 0.01% per hour
   Dynamic Premium: 0.005% × (Borrowed Amount ÷ Vault Capacity)

Real-World Example

Trade Parameters:

• Self-Capital: $1,000

• Borrowed: $4,000 (4x)

• Total Collateral: $5,000

• Exchange Leverage: 40x

• Position Size: $200,000

• β Coefficient: 3% (normal volatility)

Profit Scenario:

1. ETH price increases 0.5%

2. Position value: $201,000 (+$1,000)

3. Close position → repay $4,000 + $0.80 interest

4. Trader nets: $1,000 + ($1,000 - $0.80) = $1,999.20 (99.92% ROI)

Liquidation Scenario:

1. ETH price drops 0.3%

2. Position value: $199,400

3. Stop-loss triggers at $199,400 < MV ($4,000 ÷ 0.97 = $4,123.71)

4. Vault receives full $4,000 repayment

5. Trader loses $1,000 collateral

This refined pre-funding model creates a win-win structure: Traders access unprecedented leverage while Fund Vault providers enjoy institutional-grade capital protection. By separating collateral enhancement from exchange execution, LeverAcc maintains full non-custodial security while delivering transformative leverage capabilities.
