Polkadex Mainnet Launch 101

Polkadex’s layers of complexity are just another way in which it stands out from other DeFi projects. Find out what exactly Mainnet Launch means for Polkadex and what to expect in the next few months in this article.

As you may know by now, Polkadex is composed of three products: Polkadex Orderbook, Polkapool, and PolkaIDO. These three products make up the DApp layer of Polkadex. However, that is not all there is to Polkadex! The trustless DApp layer that contains the Orderbook, swap platform and IDO launchpad apps is maintained and secured by the Polkadex network. In other words, the Polkadex network is the Substrate-based blockchain upon which the Polkadex DApps are built. It is a network of computers that secure data and in turn are awarded tokens (PDEX). The Polkadex network also connects to other blockchains through cross-chain bridges and allows for these tokens to be moved from one blockchain to another, which has a positive impact on the overall interoperability of Polkadex.

What does this mean?

  1. Polkadex blockchain
  2. PDEX token
  3. PDEX bridges
  4. Polkadex Orderbook
  5. PolkaIDO
  6. Polkapool

Due to the Polkadex team’s aim for perfection, each of these components has to go through the following phases:

  1. Coding/developing of the logic on the blockchain
  2. Deployment of the code to the Testnet
  3. Auditing of the code while it is deployed on the Testnet
  4. Release on the Mainnet

Therefore, while most of the components that make up Polkadex are technically independent of each other, they all have one common prerequisite: the Polkadex blockchain. The Polkadex blockchain is what holds all of the separate components together and allows them to interact with each other and with other blockchains. As such, it is the most important aspect of the project since it creates the secure and verifiable environment necessary for the Polkadex DApps to flourish.

So, what exactly does the ‘Mainnet launch’ mean for Polkadex?

Metaphorically, the Mainnet launch can be seen as the completion of construction on a brand new apartment building, where the roll-out of components/products can be seen as the tenants moving into each different apartment unit within the building. The building needs to be completed and fully secured before anybody can move in. In a similar way, the mainnet needs to be live and stabilized with a healthy community of at least 100 validators before any component can be launched on top of it.

The gradual roll-out of features onto an established blockchain is an approach that is not too different from Polkadot’s launch. In fact, when Polkadot’s Mainnet was launched, users couldn’t even make balance transfers as that feature had not been activated yet. When dealing with such a complex project with a lot of moving parts, it’s important to ensure that the base layer is stable before adding more components to it. It is also important to build, audit, test and reiterate the components individually before they are deployed on the Mainnet and begin attracting large amounts of assets.

Okay, so when is the Mainnet scheduled to launch?

What comes after the Mainnet launch?

Polkadex roll-out schedule

September 2021

  • Mainnet

September/October 2021

  • ERC-20 PDEX to native PDEX migration

Q4 2021

  • Deployment of Cross-chain Bridges. If Polkadex is ready for a Polkadot parachain spot by then, those cross-chain bridges will also be opened.
  • PolkaIDO

Q4 2021/Q1 2022

  • Polkapool

Q1 2022

  • Polkadex Orderbook

While we are scheduled to release in the dates listed above, it is important to keep in mind that these dates are tentative as the roll-out of features and components onto the Mainnet will ultimately depend on the ‘Go/No Go’ evaluation from the Testnet.

Why can’t everything be launched at once like on the Ethereum network?

Difference between Polkadex and other Substrate-based projects

The role of PDEX

Since PDEX has been built specifically for the Polkadex network and its tokenomics are intertwined with the network, it is also important for it to follow through with its original release schedule and post-Mainnet native migration. The PDEX release schedule was pre-determined with the security of the network in mind and with a September 2021 Mainnet launch date target. In other words, the PDEX release schedule is not directly linked to the separate Polkadex component releases, but rather the overall timing of the Polkadex network’s launch.

Have there been delays? Will there be?

The development team has not only remained on track to meet the timelines set out in the roadmap, but we have already completed most of the code for all the components of Polkadex. This has led to a slight backlog on the frontend side, which has delayed the beta tester program and public Testnet release but has had no impact on the timing of Mainnet launches of each different component.


What about the Testnet?

The Testnet with the integrated frontend UI (simply put, Polkadex products that you can play around with) will begin a feature-by-feature rollout to beta testers this month (August 2021), starting with PolkaIDO. Gradually, Polkadex’s other components will be rolled out, first to beta testers and, a few weeks later, to the public Testnet. The exact date when everyone in the Polkadex community will get a chance to test the network and take our user interface for a spin will be announced soon.

Towards the fall, all of the components listed above will be launched on the UI-integrated version of the Testnet. That upcoming Testnet release will mark a milestone for Polkadex merely a year after its foundation as it will mean that the backend and frontend code that aims to realize the original Polkadex vision will be fully completed and released.
