HAI Use-Cases
An incomplete list of things you can build with or on top of HAI
Unique Money Markets
If Alice pays 5% per year to borrow HAI from a money market and the HAI redemption rate is -10% per year, she is effectively earning 5% per year. This is because of the expectation that HAI's market price will go down by 10% in one year. On the other hand, Bob might be lending HAI at 4% per year, but if the redemption rate is -10%, his net rate is -6%. There's the other scenario where Bob is lending HAI at 4% per year and the redemption rate is 10% per year. In total, Bob is earning 14% annually in his position (assuming that HAI will appreciate by 10% in the next year). Meanwhile, Alice, who's borrowing HAI at 5% per year, is paying a total of 15% (5% as the money market borrow rate plus the expected 10% appreciation in HAI's price over one year).
Stacked Funding Rates
If an exchange or protocol decides to offer HAI perpetuals, they will essentially allow traders to stack funding rates on top of each other. The redemption rate is similar but not identical to a funding rate. The net funding rate on a HAI perpetual is a combination of the funding rate on the platform/exchange that lists the perpetual and the redemption rate.
Options
A developer can build an options protocol that considers changes in the redemption rate to determine the price of puts/calls. This is because the redemption rate can be thought of as an intrinsic interest rate for HAI.
Pegged Coins/Synthetic Assets
Projects building pegged coins can use HAI as a more stable alternative to ETH. In case of a severe ETH market crash, HAI can offer its holders more time to unwind their positions before they get liquidated.
Yield Aggregator
Protocols that deploy capital in order to get the best yield for their users (e.g. Yearn) can leverage HAI (and its intrinsic redemption rate) to boost returns. For example, combining HAI's positive redemption rate with lending on Compound or Aave is one way to optimize earnings.
Sophisticated Arbitrageurs
Arbitrageurs (or otherwise traders in general) can look at the redemption price behavior and combine this data point with others (e.g. market sentiment) in order to find the ideal time when they should execute a trade.
Some arbitrageurs can offer specialized HAI trading services to pools of capital. They can be allowed to flash-loan funds and split the profit with the pool.
Portfolio Management Strategies
Anyone can create Set Protocol sets or Balancer pools that offer diversified exposure to HAI's redemption rate as well as other yield-bearing assets (e.g. cTokens, aTokens).
