Hydra, Cardano’s own Layer 2 solution, is making progress after the SundaeSwap decentralised exchange (DEX) successfully launched a demo on the network.

Charles Hoskinson, Cardano’s founder, bullishly tweeted: “Hail Hydra! So glad to see this demo. Hydra is coming to cardano one [decenrtalised application] DApp at a time.”

Yet, Cardano’s community and developers could still be waiting up to a year before the Layer 2 solution launches.

Despite a slight rise, the price of cardano (ADA) has not seen much positive price action following the Hydra announcement.


Hydra details

While Cardano is gearing up to launch Hydra, its purpose and methods are similar to Ethereum Layer 2 solutions, like Arbitrum or Optimism. Hydra’s goal is to bring faster transactions, higher throughputs and lower fees.

The Layer 2 network will be redirecting blockchain traffic to achieve this. An official blog post explained:

“By providing more efficient means of processing transactions off-chain for a set of users, while using the main-chain ledger as the secure settlement layer, Hydra keeps security guarantees while remaining loosely coupled to the main chain.”

Hydra is set to become a “family of protocols”. The first protocol goes under the title Hydra Head and are off-chain mini ledgers that are shared by a small community of developers. Users can then build specialised and complex protocols on top of them.

Hydra’s roadmap

The blog post and development documentation make it clear that Hydra is a long-term project, which Cardano developers are hoping will drive growth.

As outlined by software engineer Sebastian Nagel, the short-term goal is to continue developing the Hydra Head protocol. It is currently building “a solid and stable foundation for the community to build real-world applications”.

The blog post, which was published in September, said it would be six to 12 months before Hydra launched. But this depends on research, experimentation and community feedback.

ADA price movements

ADA saw a slight price rise after SundaeSwap announced it had launched a demo on Hydra. It closed 13 October at $0.377 and bounced to a high of $0.388 the following day. 

But the cardano cryptocurrency has continued into a bearish trend that it has faced since the crypto crash in May. Even its major Vasil upgrade in September struggled to lift ADA.

Some community members are hopeful and speculated that Hydra could drive “non-speculative demand for ADA”.

Nagel said: “We want this ecosystem to serve the needs of individual consumers, enterprises, professionals, and the growing list of DApps and their developers.”

But this demand for ADA has not been realised in the short-term. At the time of writing on 19 October, cardano had sunk to $0.35, down 17% in the past month.

The difference between trading assets and CFDs
The main difference between CFD trading and trading assets, such as commodities and stocks, is that you don’t own the underlying asset when you trade on a CFD.
You can still benefit if the market moves in your favour, or make a loss if it moves against you. However, with traditional trading you enter a contract to exchange the legal ownership of the individual shares or the commodities for money, and you own this until you sell it again.
CFDs are leveraged products, which means that you only need to deposit a percentage of the full value of the CFD trade in order to open a position. But with traditional trading, you buy the assets for the full amount. In the UK, there is no stamp duty on CFD trading, but there is when you buy stocks, for example.
CFDs attract overnight costs to hold the trades (unless you use 1-1 leverage), which makes them more suited to short-term trading opportunities. Stocks and commodities are more normally bought and held for longer. You might also pay a broker commission or fees when buying and selling assets direct and you’d need somewhere to store them safely.
