Three More Tezos DeFi Hackathon Teams to Keep Developing on Tezos

Three More Tezos DeFi Hackathon Teams to Keep Developing on Tezos

We continue covering the projects and plans of the participants of Tezos DeFi Hackathon 2022. Today we deal with those who work on Everscale challenges: bridges, DeBots, and NFTs.

Other participants are covered in our past features: the 34 teams who wish to continue developing on Tezos and the four that already have something to report.

What Is Everscale

Everscale or Everscale.network is one of the successors to the Telegram Open Network.

In 2018, VK and Telegram founder Pavel Durov announced the development of his own blockchain, the Telegram Open Network (TON). That same year, he led two rounds of funding and raised $1.7 billion. In 2020, Durov announced that he would cease operations and return the funds to investors due to the intervention of the U.S. Securities and Exchange Commission (SEC).

The TON team posted the code to the public domain, and the Eastern European blockchain community continued to develop the project. At first it was called FreeTON, and in 2021 it was renamed Everscale. In addition, there is another blockchain based on Telegram Open Network dubbed The Open Network.

Everscale’s main feature is the multithreading. There are several workchains in the network at the same time:

  • -1 or masterchain—for service contracts;
  • 0—for user contracts;
  • 1, 2 and so on—you can run more user-generated workchains for the purpose of upscaling.

In addition, each workchain is divided into shards (shardchains) with their own ledgers and validator groups. Their number adjusts to the current Everscale load.

The Tezos DeFi Hackathon 2022 featured two Challenges from Everscale: a bridge between Everscale and Tezos from the Broxus ecosystem, and DeBot from the Ever Surf wallet. Teams who made it through are willing to continue to work on Tezos and Everscale.

A Bridge by Radiance Team

Radiance Team produced a bridge MVP to transfer tokens between Tezos and Everscale. Schematically, it looks like this.

The user sends FA2 tokens to the depository, the relay validators confirm the deposit, the Everscale contract creates the same number of TIP3.1 tokens, and sends them to the user.

The Radiance Team bridge has a feature: if the relay’s backend does not respond and trigger token issuance on Everscale, the user can trigger the EventConfigurator contract on their own and get their tokens. Still, this will only work if there is confirmation from the validators.

The bridge is available for testing, but with a condition: the team has deployed the contracts on Hangzhounet, which may soon become unavailable.

Anzor Daurov, the team lead of the Radiance Team, said that he considers Tezos a promising direction. The team has taken a break for now, but plans to return to work with Tezos in the near future to port or bridge their own products or develop something completely new.

DeBot by DEvergence

DeBots or decentralised bots are Everscale’s invention. It’s essentially a chat-like interface for working with smart contracts. With their help, Ever Surf wallet users can stake tokens, create a multisig wallet, or play a game directly, without going to the project site and connecting the wallet manually.

One of the Challenges of Tezos DeFi Hackathon 2022 was to develop a DeBot that can work with Tezos: display the wallet balance and send assets.

Despite many differences in architecture, Tezos and Everscale have a few things in common: both blockchains use the Ed25519 curve for signing transactions and the BIP-39 standard for generating a private key. But the blockchains have different derivation paths for private key generation and hashing algorithms for the public key, so you cannot import an existing Tezos wallet into Ever Surf directly.

The DEvergence developers have solved all those problems in their DeBot.

  • wrote a script to export a key from Ever Surf into a format that Tezos wallets will understand. Thus, when a user creates a wallet in Ever Surf, they can import it into Temple or Kukai;
  • added the blake2b hashing algorithm used by Tezos to their DeBot;
  • adapted DeBot’s interface to work with Tezos nodes.

The result is Devergence Wallet, a DeBot for managing the Tezos wallet from Ever Surf.

The team plans to return to blockchain development as soon as all participants settle their matters with fulltime jobs, recreation, and studies.

A Bridge and NFT by Everangers

The Everangers team has developed an MVP for a two-direction bridge: it transfers Tezos tokens to Everscale and Everscale tokens to Tezos.

The Everangers team has big plans: to implement a relay version in Rust, establish bridge management through DAO, and release a token featuring some useful usecases.

In addition, Everangers are collaborating with another team in the NFT area. Their plan is to refine the concept, apply for a Tezos Foundation grant, and launch a multichain project on Tezos, Everscale, and NEAR.
