Holdr

Holdr is a Balancer Friendly Fork on the Aurora Chain. It’s a multi-token automated market maker (AMM) that functions as a self-balancing weighted portfolio protocol. It allows anyone to create or add liquidity to customizable pools and earn trading fees.

It mimics the concept of an index fund where assets are regularly being reallocated based on the price and returns of the assets. Index fund is a common financial instrument that helps investors to achieve risk diversification by maintaining a controlled risk exposure to a portfolio. Rather than paying a portfolio manager to actively or programmatically manage users’ funds, Holdr helps solve a similar problem with smart contracts.

1. Weighted Pools

Weighted Pools are highly versatile and configurable pools. They are ideal for general cases and enable users to build pools with different token counts and weightings, such as pools with 80/20 or 60/20/20 weightings.

2. Stable Pools

For certain assets that are expected to consistently trade at near parity (e.g. different varieties of stablecoins or synthetics) a more efficient design is the StableSwap AMM as popularized by Curve. These pools allow for larger trades of these assets before encountering significant price impact.

3. Boosted Pools

Boosted Pools will bring the best of both worlds to Liquidity Providers and Swappers. Swappers get access to deep stablecoin liquidity with near-parity exchange rates while Liquidity Providers get their liquidity positions sent to external protocols, such as Bastion.
