Challenge 12: Proportional Deposit Quote

Liquidity should usually be added in the same ratio as the existing reserves.

Task

Implement required_y_deposit.

Formula

Use:

x_deposit * y_reserve / x_reserve

Example

For:

  • x_reserve = 1000
  • y_reserve = 2000
  • x_deposit = 250

Then:

250 * 2000 / 1000 = 500
