# How it works

Our index product streamlines the process of investing in multiple crypto assets. When a user decides to buy or sell the index token, several mechanisms come into play:

* **Flash Mint:** This feature allows users to mint new index tokens by providing the necessary entry assets (e.g., ETH, USDT, USDC). These assets are then swapped through a decentralized protocol like Uniswap for the tokens that comprise the index.
* **Flash Redeem**: Users can redeem their index tokens for the underlying assets. They have the option to receive the individual tokens or swap them back for the original entry assets.
* **Swap**: For smaller transactions, users can swap their entry tokens directly for index tokens or vice versa through swap pools. This feature provides flexibility and convenience for managing investments.

Our product used historical data to backtest and validate the selection of tokens and the rebalancing parameters. This ensures that the allocation has not been overly concentrated in any single asset and each component token has had an effective allocation, promoting a balanced and diversified investment approach.
