Yak Swap x Hubble Exchange

Yield Yak has partnered with Hubble Exchange to integrate Yak Swap. The integration allows Hubble Exchange’s traders and makers (LPs) to swap between collaterals within their margin account and settle negative hUSD balances using collateral. To celebrate the partnership Hubble are giving away 50 Hubble Space Cat NFTs.


  • Yak Swap has been integrated to provide Hubble users with the best price when making collateral swaps
  • To celebrate the partnership, the first 50 YAK holders to trade on Hubble from October 11th at 08:00 UTC will win a Hubble Space Cat NFT. Space Cats can be used to vote on the governance of the Hubble Exchange DAO.

Why is Hubble Exchange integrating Yak Swap?

Yak Swap, Yield Yak’s liquidity aggregator and swap tool, provides the best prices for swaps on Avalanche with the deepest liquidity coverage and zero aggregator fees. This makes Yap Swap a highly competitive aggregator, providing Hubble Exchange’s traders and makers the best execution route when they need to settle their hUSD debt with the protocol.

“It’s an honour to integrate and work with Yield Yak. They’re OGs in the Avalanche-Ecosystem and have a strong track record of building very relevant products. This integration marks the beginning of our relationship with Yield Yak and we look forward to exploring more synergies to grow the derivatives landscape on Avalanche together.”

50 Hubble Space Cat NFTs to be awarded to YAK holders x Hubble users

What is Hubble?

Hubble Exchange is a multi-collateral Perpetual Futures Exchange. Traders and Makers can add assets such as AVAX and ETH as collateral for their positions. The PnL from these positions is reflected in Hubble Exchange’s unit of account: hUSD.

When a position/account is profitable, users have a positive hUSD balance. However, when the market moves against their account/position, users experience a negative hUSD balance. A negative hUSD balance prevents users from withdrawing their collateralized assets, until the hUSD debt is settled.

In the past, traders had to deposit fresh USDC to Hubble Exchange to mint hUSD in order to clear their hUSD debt. With the implementation of this integration with Yak Swap, traders and makers are enabled to settle their hUSD debt by selling the collateral that is already deposited within Hubble Exchange to clear their debt, whilst getting the lowest slippage and best prices on Avalanche.
