In the ever-evolving world of NFTs, collectors and traders are constantly seeking platforms that not only enhance their trading experience but also safeguard their interests in a market known for its volatility and complexity. Amidst this backdrop, Memswap emerges as a beacon of innovation, promising a paradigm shift in how we approach NFT trading.

The allure of non-fungible tokens (NFTs) has captivated a diverse audience, ranging from digital art enthusiasts to serious investors looking to capitalize on this unique asset class. However, as the market expands, it faces growing pains: transaction inefficiencies, privacy concerns, and the often opaque nature of pricing and execution strategies. These challenges have not only dampened the user experience but also raised questions about the sustainability and inclusivity of the NFT ecosystem.

Enter Memswap, a groundbreaking protocol designed for a post-MEV (Miner Extractable Value) world, where the focus shifts from extracting value from users to maximizing value for them. This new player in the field stands out with its promise of best-in-class price execution, minimal centralization, rapid transaction processing, privacy-preserving features, and an unprecedented level of market composability. For NFT collectors, these are not just incremental improvements; they represent a leap towards a more equitable and efficient trading environment.

As we delve deeper into the mechanics and implications of Memswap, it becomes clear that this is not just another trading platform. It's a reimagining of the NFT marketplace, where the needs and concerns of collectors are not just heard but actively addressed. In this editorial, we will explore how Memswap is setting new standards in NFT trading and why it could be the game-changer that collectors and traders have been waiting for.

Memswap: A New Era for NFT Trading and Beyond

Benefits for Memswap Originators (Apps/Wallets)

Simple Integration UX: At the heart of Memswap's appeal for application developers and wallet providers is its user-friendly integration process. This simplicity is not just a matter of convenience; it's a catalyst for widespread adoption, enabling a diverse range of platforms to easily tap into Memswap's capabilities. By lowering the barrier to entry, Memswap paves the way for a richer, more interconnected NFT ecosystem.

Open-source, Hostable Matchmaker Infrastructure: In a landscape where dependence on third-party services often translates to compromised efficiency and increased costs, Memswap's open-source, hostable matchmaker infrastructure stands out. This approach empowers originators with greater control and autonomy, ensuring that their reliance on external entities is minimized, if not entirely eliminated. This level of independence is crucial for maintaining a robust and resilient trading environment.

Flexible Originator Fees: The flexibility in setting up fee structures is another cornerstone of Memswap's design. Whether it's a percentage-based model or a more innovative approach like a percentage of surplus fees, this flexibility allows originators to tailor their revenue models to fit their unique needs and market dynamics. Such versatility is not just beneficial; it's essential in a market as diverse and dynamic as NFT trading.

Core Contributions of Memswap

Mempool Order Distribution: Memswap's innovative use of the Ethereum mempool for order distribution, through a mechanism known as intentful transactions, marks a significant advancement in order execution. This approach, which allows for the option of centralized orderbooks, provides users with an improved trading experience. It's a testament to Memswap's commitment to balancing decentralization with practical efficiency.

Order Flow Auctions (OFAs): The platform's open and modular design supports various order flow auction designs, including matchmaker (last block) auctions and builder auctions. This flexibility enables applications to either run their own matchmakers or collaborate with reputable actors, further enhancing the platform's versatility and appeal.

High Signal Privacy: In the realm of high signal intents, privacy is paramount. Memswap addresses this through MEV-share’s “programmable privacy” feature, allowing for partial order concealment. Additionally, the option for complete privacy through direct routing to solvers is a game-changer, offering users the discretion they often seek in high-stakes trading scenarios.

NFT Composability: One of Memswap's most groundbreaking contributions is in the realm of NFT composability. By addressing the fragmentation and restrictions in NFT liquidity, Memswap unlocks new possibilities for trading and collecting. This shift in complexity to professional solvers is a significant leap forward, enabling a level of fluidity and creativity in NFT trading that was previously unattainable.


As we look towards the future of NFT trading, it's clear that Memswap is not just a new player in the market; it's a harbinger of a new era. With its innovative approach to order execution, privacy, and market composability, Memswap is poised to redefine the NFT landscape. Memswap adeptly navigates the market's complexities, offering advanced trading features like cross-marketplace sweeping, purchase currency flexibility, slippage tolerance, gasless transactions, royalty normalization, and taker fees. Its innovative approach overcomes restrictions imposed by certain marketplaces and NFT standards, retaining composability through bundles of transactions sent from a solver's EOA.

In the context of our discussion on Memswap and the broader NFT market, it's pertinent to address a parallel development in blockchain technology: the evolution of account models, particularly in a multi-chain environment.

Smart contract wallets, while innovative, face significant challenges in multi-chain scenarios. The primary issue lies in the need to synchronize state and configuration across multiple chains, a process that can quickly become complex and unwieldy.

The emerging solution lies in making EOAs programmable via Multi-Party Computation (MPC). Although more technically challenging and still in development, MPC offers many of the same features as smart contract wallets, such as device/session keys, permissioning, and account recovery. Crucially, it achieves this with seamless cross-chain functionality.

Some notable solutions in this space include:

The convenience of using the same wallet seamlessly across all chains is likely to outweigh the benefits of a modular smart wallet for many users. MPC offers a balance of "good enough" programmability and best-in-class compatibility, reinforcing the enduring relevance of EOAs in the blockchain ecosystem.
