SwapBased Perps Exchange

BLP Overview

BLP consists of an index of assets used for swaps and leverage trading. It can be minted using any index asset and burnt to redeem any index asset. The price for minting and redemption is calculated based on (the total worth of assets in the index including profits and losses of open positions) / (BLP supply).

These are the index assets:

  • axlUSDC

  • USDbC

  • DAI

  • ETH

Holders of the BLP receipt earn 65% of platform fees distributed in ETH. Note that the fees distributed are based on the number after deducting the network costs of keepers, keeper costs are usually around 1% of the total fees.

As BLP holders provide liquidity for leverage trading, they will make a profit when leverage traders make a loss and vice versa. Past PnL data, BLP price chart, and other stats can be viewed on the Stats page.

Minting and Redeeming

Minting BLP

  • A list of BLP tokens can be found on the Dashboard at any time.

  • Fees will be lower for tokens that the pool has less of, check the "Save on Fees" section to get the lowest fees.

  • Key in the amount of BLP you'd like to purchase on the Buy BLP section of the Buy page.

Fees for buying BLP will vary based on which assets the index has less or more of, the Buy BLP page will show which assets have the lowest fee.

Redeeming BLP

Key in the amount of BLP you'd like to redeem in the Sell BLP section of the Buy page. Note that there is a minimum holding time of 15 minutes after minting before you can redeem or stake BLP tokens.

Rebalancing

The fees to mint BLP, burn BLP, or perform swaps will vary based on whether the action improves the balance of assets or reduces it. For example, if the index has a large percentage of ETH and a small percentage of USDC, actions that further increase the amount of ETH the index has will have a high fee while actions that reduce the amount of ETH the index has will have a low fee.

The token weights can be seen on the Dashboard.

Token weights are adjusted to help hedge BLP holders based on traders' open positions. For example, if a lot of traders are long ETH, then ETH would have a higher token weight, if a lot of traders are short, then a higher token weight will be given to stablecoins.

If token prices are increasing, then the price of BLP will increase as well, even if a lot of traders have a long position on the platform. The portion reserved for long positions can be treated as stable in terms of its USD value since if prices increase the profits from that portion will be used to pay traders, and if prices decrease, the losses of traders will keep the USD value of the reserve portion the same.

If a lot of traders are short and larger weights are given to stablecoins. BLP holders would have a synthetic exposure to the tokens being shorted, e.g. if ETH is being shorted then the price of BLP will decrease if the price of ETH decreases, if the price of ETH increases then the price of BLP will increase from the losses of the short positions.
