The 101 on Our ETH Staking Yield Swap Listings

Invented by BitMEX, our upcoming ETHYLD contract allows traders to “swap” the variable yield that emanates from staking ETH on Lido (floating rate) for a fixed interest rate (fixed rate) - and vice versa - with up to 2x leverage. There are two sides to an ETHYLD swap trade. Each day during the life of the contract:

1. One trader, the “Payer”, pays thefixed rateand receives thefloating rate.

2. The other trader, the “Receiver”, receives thefixed rateand pays thefloating rate.

A  trader who has staked ETH on Lido - and also received fixed on an ETHYLD swap contract - willnetreceive thefixed rateon their staked ETH (thus converting the uncertain daily variable rate that is derived from staking ETH on Lido into a known fixed rate). This is illustrated below:

Thefixed raterepresents a trader’s best guess of the average daily ETH staking yield - from the inception of the contract until maturity. It’s the rate that traders speculate on, and will be an annualised rate.

Settlements will occur daily at 12:00 UTC.

Our upcomingETH staking yieldswap may be ideal for:

• Users who have staked ETH on Lido, and wish to lock in a fixed yield

• Users who are using other methods to stake ETH, and wish to use ourETH staking yieldswap contracts as an indirect hedge

• Speculators who wish to take positions on the value of ETH staking or validator rewards

• Anyone with holdings - or an interest - in ETH

ETH Staking Yield Swap Contract Specs

Like all crypto derivatives contracts on BitMEX, it is possible for ETHYLD traders to take a leveraged position. In addition, traders can also hold a position as long as they allocate enough margin to satisfy the maintenance margin requirement - once this is not the case, the trader will get liquidated. However, there are also several key differences between our ETHYLD listing vs. other crypto derivatives listings that users should be aware of:

• Traders ‘Pay’ or ‘Receive’ the fixed rate on an ETH staking yield contract, rather than Buy or Sell

• If a trader Pays, they will pay the fixed rate and receive the floating rate.

• If a trader Receives, they will receive the fixed rate and pay the floating rate.

• The market price of an ETHYLD swap contract on the exchange is the fixed rate.

• The floating rate is paid to the ‘Payer’ positions by the ‘Receiver’ positions each day at 12:00 UTC, in exchange for paying/receiving the fixed rate. Details of the daily interest rate calculations are shown below:

  • For example, a trader paid 4% on 1 ETH notional of ETHYLD swap contracts. If the floating rate on a particular day is 4.5%, the net amount received by the trader will be:1 ETH x (4.50% - 4.00%) x (1 / 365) = 0.00001370 ETH

• BitMEX charges traders (on both sides) a fee of 0.0005% of the position when Floating Funding payments are made (so that a position of 1 ETH will attract a Floating Funding fee of 0.000005 ETH).

• The Position and Settlement Values of an ETHYLD swap contract both depend upon the number of days remaining on the contract.

  • • If a trader Pays 4.00% on 1 contract (which has a notional size of 1 ETH), and there are 100 days until expiry, the Position Value is:(1 ETH x 4.00% x 100 / 365) = 0.000055 ETH

    • If a trader closes out their position by Receiving 4.20% on 1 contract and there are still 100 days until expiry, their PnL (Settlement Value) is:(1 ETH x (4.2% - 4.0%) x 100 / 365) = 0.0005480 ETH

• If there are now 99 days left, the Position Value will decrease to:(1 ETH x 4.00% x 99 / 365) = 0.0108493 ETH
