• Devnet Whirlpools
  • devUSDC / devUSDT 1
• Calculations:
  • price = (sqrt_x64_price >> 64)^2 * 10^(decimals_a - decimals_b)
  • sqrt_price = (price / 10^(decimals_a - decimals_b)) << 64
  • Token amounts:
    • Token A: (liquidity << 64) * (upper_sqrt_x64_price - lower_sqrt_x64_price) / (upper_sqrt_x64_price * lower_sqrt_x64_price)
    • Token B: (liquidity * (upper_sqrt_x64_price - lower_sqrt_x64_price)) >> 64
  • Liquidity:
  • Total Fee = swap_amount * ( fee_rate / 1_000_000 )
