Please describe your proposed solution

We recognized a significant challenge in the NFT space on the most decentralized blockchain. Despite its decentralized nature, the majority of NFT transactions are concentrated on just one private and profiting platform. In response, we set ourselves on a mission to level the playing field and foster more competition by building a solution that has the potential to empower other and/or specialized marketplaces and contributors in the ecosystem.

Our proposed smart contract incorporates multiple on-chain affiliate levels and dynamically splits service fees based on various factors. These factors include the marketplace where the NFT is Auctioned, the marketplace where the final bid occurred, and the contributors involved in the NFT sale (link affiliate). Unlike traditional smart contracts, where service fees are exclusively received by the contract owner, our approach is different and serves not only one business but the whole community.

We are going to apply the same philosophy as on instant buy/sell/offer SC, funded in round 11, to accomplish this goal with Auction SC.

Please define the positive impact your project will have on the wider Cardano community

New businesses can build their products and integrate the Cardano blockchain more easily and without the high initial costs, expertise, and traffic/liquidity hoarding before such projects can become competitive.

Our ultimate goal is to establish this smart contract solution as the industry standard. By adopting our smart contract, marketplaces can rather focus on new features or become a niche marketplaces fostering healthy competition beyond the realm of smart contracts.

What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

We are fully transparent with our business entity based in Prague, Czech Republic and we are building with guidance and cooperation with strong entities in Cardano. We have already built an instant buy/sell/offer SC under the funding from the previous round and we believe we have the capability to build another SC with the same logic.

The feasibility of the project has been discussed with auditing firms and we are certain the Auction's SC would be a suitable tool how to establish pricing in newly entering industries such as RWA and Gaming.

What are the key milestones you need to achieve in order to complete your project successfully?

Milestone 1: Designing

How does the cost of the project represent value for money for the Cardano ecosystem?

Since we are proposing this Smart Contract to be an Industry standard model for Cardano NFTs Auctions, we decided to employ Senior developers and professional partners for Internal Audit, Code design and Review. Despite a professional team, rates still represent the industry average for their respective seniority level. Smart Contract can easily become a single point of failure and high risks of funds locked or lost are present if the code is not built with a high precision.
