Interview - Cardano NFTs #064: Yepple

Original Placement:

Today’s Cardano NFT project is a blockchain development company on Cardano helping projects mint their NFTs and create utility for them with custom solutions: Yepple.

The previous guest was a project featuring the work of Victor Hugo, an artist that is behind popular projects like Danketsu and Omen.

This column is where I invite NFT projects to share their stories and vision as a way to connect with and learn about the Cardano Community.

Hey, glad to have you here. Please introduce your team, where are you from, what are your backgrounds?

Thanks for doing this! We’re Yepple, a blockchain development company on Cardano that handles everything related to NFT minting to NFT staking and custom solutions.

Our team consists of a few US and Canadian citizens as well as a Romanian. Our backgrounds vary from deep tech to customer care.

What is Yepple? What are you bringing to Cardano and why have you chosen this ecosystem in particular?

As I mentioned previously, we’re a blockchain development company on Cardano. We help projects mint their NFTs, create utility for them with custom solutions, organize complex NFT transformations and more. We also help individuals with their stake pool creation and maintenance. As a side note, we are also expanding to the sports industry creating engagement platforms for sports teams. We understand that bringing Web 3 into sports is hard right now, which is why we’re starting with a standard Web 2 approach.

We chose Cardano because of its NFT/token infrastructure and off-chain processing to save countless fees. Everything on the other chains is smart contract-based which not only has its own risks but also makes dev companies somewhat redundant for minting.

Can you share about your experience developing on Cardano? What are the pros and cons of the eUTXO model, Plutus and so on?

Several of our developers had experience working on Ethereum before we formed Yepple. Choosing Cardano as our focus was a very intentional decision based on the technology and the community.

On the technology front, the two driving factors were the eUTxO model and the support for native assets. Together, these two features enable a plethora of innovation and new approaches to project asset management and user experience. The ability to build and interpret complex transactions containing NFTs and fungible tokens from any number of collections is what has driven so much innovation in the NFT sector of Cardano.

Also, a transaction’s deterministic nature guarantees no failed transactions for users because of the eUTxO model’s ability to determine all inputs and outputs of a transaction before submitting the transaction to the blockchain. While this is an amazing feature, it’s not without costs — particularly to user experience.

Developing on Cardano, we have seen many users get frustrated by their wallet failing to build transactions. The culprit is usually minimum eUTxO fees or ADA that is locked with tokens. The wallet might say there is 20 ADA, but you might only have 10 ADA free to spend because of your tokens.

The eUTxO model also suffers during high congestion over a shared resource (e.g. a popular NFT mint); whether the minting service uses multi-sig or standard payments, there is extra leg work needed to manage transactions compared to EVM chains. This can lead to situations where users get confused in a complicated dApp experience.

While the UX on Cardano can still be rough around the edges, we are incredibly firm in our support of the blockchain’s fundamentals and confident that UX and development capabilities on Cardano will continue to improve to match the power of the underlying blockchain as time goes on.

What do you think needs to happen for Cadano to reach mass adoption? Where do builders and creators need to focus?

Cardano’s native assets let users safely hold what they own in their wallets, avoiding the need for interactions with unverified and potentially malicious smart contracts. This makes Cardano much more approachable and safe for unfamiliar users when it comes to a lot of common activities. With that said, Cardano makes a more convincing case for attracting individuals who are hesitant and even scared about using Web3.

Therefore, Cardano is poised for collectibles and utility-driven assets that can assist modern businesses with their marketing and operations.

In conclusion, we believe that Cardano builders and creators must actively look at/create modern businesses with collectibles and utility-driven assets in mind. Token-gated systems for communities, digital collectibles linked to real-life rewards, profit-sharing initiatives, and more are all examples of things that can be done.

At Yepple, we spearhead the sports industry with our fan engagement system, which will utilize digital collectibles for real-life experiences and prizes. The first step to getting Cardano adoption is building an ecosystem of passionate users and then introducing this new technology, which is how we approach our product.
