ETHNY JUNE 2022 — CONNEXT HACKATHON WINNERS


ANOTHER GREAT HACKATHON HAS JUST WRAPPED UP IN NEW YORK!

With 1500 attendees and 251 project submissions, this was the biggest event for
ETHGlobal this year.



It was fantastic to meet old friends and new people that learned and were mind
blown by what Connext can do: upgrading a dApp to crosschain has never been
easier.

Here is a recap of what happened.


WORKSHOP: 🛠 BUILDING CROSSCHAIN XAPPS WITH CONNEXT

Layne, co-founder and head of R&D, and Luke (from the Nomad’s team) ran a
workshop on how to build xApps, exploring crosschain transfers of tokens, how to
perform xchain governance, and execute xchain tokenless data transfers in the
most secure way.



You’ll be able to find it on the Connext Youtube Channel together with other
videos and tutorials.


CONNEXT AWARDS FOR THE BEST XCHAIN PROJECTS



Out of the numerous submissions we received, we decided to award CrossFader
built by an anonymous developer and Jorge with the top prize of this hackathon.

Crossfader is crosschain transaction anonimizer.
We believe privacy is a key right of internet users, and tools like this help to
promote a privacy-first environment across any blockchain.

The project leverages zk snarks and cross chain liquidity routing to initiate
privacy preserving transactions on any chain in the growing EVM ecosystem. The
Connext API is used to transfer tokens cross chain into a pool in which users
can prove they are members of, without revealing their initial depositing
address.

The potential for anonimous crosschain transactions is still untackled — we were
impressed by the ability of the team to deliver an end-to-end working MVP, and
their capacity to create the advanced cryptographic proofs to assemble the tool.



Note: the name of the project was changed after the submission



We also recognized the potential and awarded the following projects:


FOR THE XDEFI CATEGORY:

DEXcellence, for the potential of a new frequent batch auction crosschain DEX
that promises more efficient and MEV protected trades: privacy is built-in by
never broadcasting order data before transactions and settlements occur.

The team developed a frequent batch auction market with on-chain price discovery
and on-chain transactions and settlements. Prices are set by call auctions
off-chain. Orders are batched and executed at predetermined intervals, and are
maintained off-chain without visibility to market participants to prevent
front-running. The clearing price ensures that volume and fairness is maximized
at each auction. This is in contrast to continuous order books, which are highly
time-sensitive and therefore susceptible to front-running and price impact, and
AMMs which suffer from high slippage and impermanent loss.Learn more.


FOR THE XNFTS CATEGORY:

Forest, a project focused on social impact that aims to gamify the use of carbon
credits.
Players need to buy BCT (tokenized carbon credits) and feed treesNFTs, a
representation of trees. The beauty of their NFTs is that they will be natively
crosschain, allowing them to be seamlessly moved across different blockchains
and potentially gamify also this aspect (find some special tools on specific
chains only), together with the opportunity to tackle multiple NFT/GameFi
communities. Learn more.

NFTBlender. A tool to combine existing NFTs into a newly minted one, generate
via a ML algorithm that can combine the art of the parent NFTs.
The mint generates a crosschain NFT using NFTHashi, giving it the potential to
freely move across any chain in a secure way.



We are extremely happy to see that projects born at previous hackathons like
NFTHashi are now used as a base for new exciting use cases!

The crosschain-money-lego wave has just started.


ABOUT CONNEXT

Connext is a network for fast, trustless communication between chains and
rollups. It is the only interoperability system of its type that does this
cheaply and quickly without introducing any new trust assumptions. Connext is
aimed at developers who are looking to build bridges and other natively
cross-chain applications. To date, over $1.5b in transactions have crossed the
network.

SUPERFLUID INTEGRATES CONNEXT: A XCHAIN STREAMING BRIDGE IS BORN

Superfluid, Nomad and Connext are excited to unveil a new collaboration and
technical integration that is set to create a new primitive in the blockchain
ecosystem: fluid streaming of tokens across any domain and L2. — The evolution
of finance, work, money. Tokens are the best tool humanity has created to
exchange value between entities — individuals and companies. However these
transactions on the blockchain are still respecting a paradigm of the
traditional world of single, specific, individual tranches: Alice sends 1 ETH to
Bob, Tim pays 1 BTC for a service.

BUILDING CROSSCHAIN APPS (XAPPS)

Upgrade your dApp to xChain — Connext lets builders create secure xchain dApps
(xapps). Our network is the only way to build xapps that retain the security of
underlying blockchains. What are xApps? xApps (pronounced “zaps”) are
decentralized applications that perform operations between independent
chains/execution environments, Ethereum and Avalanche, Polygon and Polkadot, but
also Optimism and Arbitrum, for example.
