# Features Bundles give you strong controls to protect and improve your setup, plus extra wins that make managing rewarding and flexible. ### Customise weights Easily tweak weights or add/remove assets with smooth transitions and one-click migrations. Adjust the weights of underlying tokens in response to market conditions, updating shares to handle market moves with gradual rollouts (7–180 days) to maintain stability. Change the mix by adding or dropping tokens with easy tools, allowing one-click moves to new versions for everyone. ### Threshold-Based Rebalancing Implement a threshold-based system for token weights, where you set deviation limits (0.1% to 20%). This automatically rebalance underlying assets when they drift too far from their target weights—for example, with a 10% threshold on a 30% target, rebalancing kicks in if the weight falls to 20% or climbs to 40%—enabling a **"buy low, sell high" strategy** for stronger long-term returns. Learn more in the [Rebalancing strategy](/performance/rebalancing-strategy.md) page. ### Flexible Settings Updates Bundles empower curators to revise all configurations at any time, ensuring ongoing optimization and alignment with strategic objectives. This feature grants unparalleled flexibility, allowing adaptations to market conditions, user feedback, or performance insights without necessitating a complete overhaul. * **Mint and Burn Fees (0.1% - 2.5%)**: Set customizable fees for minting and burning tokens to balance sustainability with user accessibility. Lower fees can attract more participants and increase liquidity, while higher settings support advanced management strategies, ultimately contributing to the bundle's economic viability. * **Curator Fees (0% - 25% of Mint/Burn Fees)**: Allocate a portion of generated fees as compensation for your bundle management and growth. This incentivizes diligent management by rewarding your effort to grow your bundle. * **Rebalancing Threshold (0.1% - 20%)**: Adjusts deviation limits for underlying assets, enabling adaptation to market conditions. A narrower threshold ensures precise alignment with targets by keeping assets closer to their initial weights through more frequent rebalancing, ideal for periods of low volatility. Conversely, a broader threshold reduces rebalancing frequency. * Decreasing the threshold → gradual transition over 7 days (prevents immediate rebalancing surge) * Increasing the threshold → immediate effect (allows quick response to market conditions) * **Transition Period (Duration: 7 Days - 6 Months; Start: 7-30 Days)**: Define the rollout duration and initiation timeline for changes. Shorter durations enable rapid responses to market shifts, while longer periods provide stability during transitions.
