PLV Score Calculation

PLV (Price, Liquidity, Volume) score is calculated using:

• Price Score (30%): Based on distance from 0.5 (more directional = higher score)
• Volume Score (30%): Normalized to $1M cap
• Liquidity Score (40%): Normalized to $100k cap

Formula:

priceScore = min(|price - 0.5| * 2 * 100, 100)
volumeScore = min((volume / 1,000,000) * 100, 100)
liquidityScore = min((liquidity / 100,000) * 100, 100)
plvScore = round(priceScore * 0.3 + volumeScore * 0.3 + liquidityScore * 0.4)

Bridge Flow

1. User enters SOL amount to deposit
2. System fetches real-time bridge quote from Wormhole
3. User signs Solana transaction in wallet
4. Transaction submitted to Wormhole guardian network
5. VAA attestation generated (10-15 minutes)
6. USDC redeemable on Polygon for Polymarket trading
