ICE boosts

Holding ICE multiplies your AQUA rewards as a liquidity provider — up to x2.5, based on your ICE share versus your pool share.

Liquidity providers who hold ICE receive a reward boost on their AQUA rewards, up to x2.5. The boost is determined by two ratios: your share of the total ICE supply and your share of the pool. It is distinct from the up-to-10x lock multiplier, which determines how much ICE you receive for locking AQUA.

How the boost is calculated

Aquarius uses the working-balance model known from Curve's veCRV boost:

boost = min(0.4 × deposit + 0.6 × pool_liquidity × your_ICE / total_ICE, deposit) / (0.4 × deposit)

You reach the full x2.5 when your share of the total ICE supply is at least as large as your share of the pool. A larger pool share with the same ICE lowers the boost toward 1x.

The inputs differ per reward system:

Reward system	deposit	pool_liquidity
AMM rewards	Your LP tokens in the pool	The pool's total LP tokens
Stellar DEX (SDEX) rewards	Your order-book liquidity for the market	Total order-book liquidity for the market, weighted by time on book, spread proximity, and offer fulfillment

Worked example — suppose the total ICE supply is 50 billion:

• You hold 5 million ICE (0.01% of supply) and provide 0.01% of a pool's liquidity: full x2.5 boost. A 10% base rewards APY becomes 25%.

• You double your pool share to 0.02% with the same ICE: the boost drops to x1.75.

The boost is recalculated hourly and shifts as other providers deposit and withdraw. Claiming rewards refreshes your boost.
