🥃Liquidity Pools

Helios' core function is to allow users to trade digital assets safely with low fees and slippage.

Slippage is the difference between the current market price of an asset and the price at which the actual trade is executed. This difference can result in a smaller amount (higher price paid) or a more significant amount (lower price paid) of desired tokens returned from a trade.

To provide access to the best market prices, we have identified two types of assets:

• Stable Pools (sAMM)

• Variable Pools (vAMM).

Stable Pools (sAMM)

Stable Pools are designed for assets with low or no volatility. This means that the pricing formula used for these assets allows for low slippage even on large trade volumes.

The formula is

$$x³y + y³x ≥ k.$$

Variable Pools (vAMM)

Variable Pools, on the other hand, are designed for assets with high price volatility.

These pools use a familiar AMM formula

$$x × y ≥ k$$

Where x represents the amount of the first asset in the pool, y represents the amount of the second asset in the same pool, and k is a balancing constant.

Fee Structure

Helios' fee structure is adjustable, allowing for competitive swap pricing and strong revenue generation for veHELI voters, leading to increased staking rates and liquidity provision.

Transaction fees may be adjusted over time:

• vAMM: 0.2%

• sAMM: 0.03%.
