Hubble Exchange review

Hubble Exchange was a decentralized perpetual futures exchange on Avalanche that offered cross-margin trading with multiple collateral types. Its operator announced in May 2024 that it was closing down, so this page covers its design and its shutdown rather than a service you can use today.

Our verdict on Hubble Exchange

2.5/10

Hubble Exchange was a perpetual futures venue on Avalanche built around cross-margin and multi-collateral trading. Its operator announced in May 2024 that it was closing down, trading would stop and positions would be wound down, so it is not a service to use now. The main takeaway is that the design is documented, but the exchange itself is no longer a live option. Readers researching derivatives on Avalanche should look at currently operating platforms instead.

What is Hubble Exchange?

Hubble Exchange was a decentralized perpetual futures platform on Avalanche. Its listing describes multi-collateral, cross-margin trading, meaning traders could post more than one type of collateral against a shared pool that backs all their open positions. DefiLlama classifies it under derivatives and records a listing date of August 2022.

The project is no longer operating. Its Medium announcement from May 17, 2024 states that Hubble Exchange would close down, that trading would cease and that all positions would be wound down. Public reporting repeat this notice, so it is the most recent event in the material available.

The homepage could not be fetched, and the project does not include audit details, a fee schedule or the names of the team behind the exchange. Its DefiLlama total value locked figure was about 2 dollars at the time of the data pull, which is consistent with a service that has stopped taking deposits.

How Hubble Exchange works

A perpetual futures exchange lets a trader open a position that follows an asset's price without an expiry date. The trader posts collateral, chooses a leverage level and goes long or short. Positions are marked to market continuously, and if losses reduce the collateral below a required level the position can be liquidated.

Cross-margin means the collateral is pooled across all open positions, so a gain on one can support another, and a loss on one draws on the shared balance. Multi-collateral means several asset types can be posted to that pool rather than a single one.

Hubble Exchange ran these mechanics on Avalanche. The project does not describe its contract design, oracle sources or liquidation rules in detail, so those specifics cannot be confirmed from the material available.

Pros and cons

What we like

Its design of cross-margin and multi-collateral perpetuals was a recognized approach to capital-efficient derivatives trading.
The project announced its closure directly through its own Medium channel, giving users a clear public record.
It was listed on DefiLlama with an Avalanche deployment, so its chain footprint is easy to check.
Its listing and closure notice remain publicly accessible for anyone researching the project.

Watch out for

The project announced in May 2024 that it was closing down, so it cannot currently be used for trading.
Trading was to cease and open positions were to be wound down, which leaves no active venue to rely on.
Tokens and public reporting that share the Hubble name belong to unrelated projects on other chains, which makes it easy to buy the wrong asset.
The project does not include audit reports, team details or a published fee schedule, so the safety profile cannot be checked from them.

Hubble Exchange fees

The project does not include a published fee schedule for Hubble Exchange. Trading fees, funding rates and any liquidation costs would normally be shown inside the trading interface or in project documentation, and neither was available in the material reviewed.

Is Hubble Exchange safe?

Hubble Exchange announced in May 2024 that it was closing down and that trading would cease. Users should treat the platform as closed and should not deposit funds into any contract or site that claims to be the exchange.

Public sources list two audits on DefiLlama, but the audit firms, dates and scope are not in the material reviewed, so they cannot be verified here. The project does not publish custody details, and smart-contract and counterparty risk applied to any perpetuals venue of this type.

Derivatives with leverage carry a real risk of rapid losses and liquidation. Trading is restricted to adults aged 18 and over, and people should use it only with money they can afford to lose. Check that online derivatives trading is legal where you live before using any platform of this kind, and use responsible trading limits if you do trade.

Is there a Hubble Exchange token?
