Borrowing Incentives
QiDao rewards users for borrowing MAI against their cryptoassets.

What are borrowing incentives?

Some Vault types on Polygon receive 0.05 Qi per block as a borrowing incentive, that is then distributed between all the users who have a healthy Collateral to Debt Ratio (CDR). A healthy CDR is defined as 25% to 270% above the liquidation ratio. For example, a vault with a liquidation ratio of 130% would need to stay between a CDR of 155% and 400% in order to receive vault incentives.

What are vault types?

Vault types refer to what collateral is being used to back MAI. Borrowing on QiDao is separated by the collateral that MAI is borrowed against. For example, WETH-backed loans are made through WETH vaults and WBTC-backed loans are made through WBTC vaults.

How much will I receive for borrowing MAI?

Your share of borrowing incentives is decided based on the proportion of MAI you've borrowed from a vault type compared to all the MAI borrowed from that vault type. For example, let's say you borrowed 100 MAI against WETH, and there is a total of 1000 MAI backed by WETH on QiDao. You will receive 10% of all borrowing incentives (100 MAI / 1000 MAI = 10%).

How are rewards distributed?

Borrowing incentives are distributed weekly on Wednesdays for the previous week's borrowing activity. Rewards are airdropped to users' addresses.

How can I calculate my APR?

Follow the equation below to calculate your borrow incentives APR per vault:
APR = (Weekly Qi received * Qi Price * 52) / MAI borrowed
Jane received 100 Qi in a week for borrowing 1000 MAI. Assuming $1 Qi price, her APR would be the following:
100 * 1 * 52 / 1000 = 520% APR
