The Journey from Anchor to Backpack Exchange

Armani Ferrante's journey in the cryptocurrency space is nothing short of remarkable. From developing Anchor, the preeminent open-source framework for writing Solana programs in Rust, to launching Mad Lads, one of the top NFT collections across all chains, Ferrante has consistently been at the forefront of innovation in the Solana ecosystem. His latest venture, Backpack Exchange, represents a bold step into the world of centralized exchanges, leveraging his experience as a former FTX engineer to create a next-generation financial institution.

Ferrante's path to creating Backpack Exchange was not a straight line. It began with his work on open-source projects for Solana in September 2020. For over a year, he focused on developing various tools and applications, including wallets, DeFi protocols, and developer tooling. As Solana's network grew exponentially, Ferrante found himself encouraged by the community to continue his work. This led to the creation of his company in December 2021, with the initial goal of simply "making useful things in crypto."

The Birth of XNFTs and Backpack Wallet

One of the first major ideas that Ferrante and his team pursued was the concept of XNFTs. The premise was simple yet revolutionary: instead of tokenizing just images, they would tokenize code. This fundamental primitive allowed them to build a next-generation wallet and, by extension, a Web3-native crypto application ecosystem. Ferrante describes it as "a Web3 iOS Android, if you want to put it in those terms."

The development of XNFTs coincided with the creation of the Solana Mobile Stack (SMS), positioning Backpack at the forefront of on-chain applications with the wallet serving as the primary vehicle for distribution. This innovative approach set the stage for what would become a comprehensive ecosystem of interconnected products and services.

Mad Lads: Eating Their Own Cooking

To showcase the potential of XNFTs and gain firsthand experience in building an NFT community, Ferrante and his team decided to launch Mad Lads. This project was more than just a demonstration of their technology; it was an exercise in "eating their own cooking." By creating an NFT project themselves, they gained invaluable insights into the challenges and opportunities within the space.

Ferrante explains, "It's one thing to build for other people. It's another thing to build for yourself and to really intimately understand the process of what it's like to build one of these NFT communities." This hands-on approach allowed them to refine their tools and better understand the needs of creators and users in the NFT ecosystem.

The FTX Collapse: A Turning Point

The collapse of FTX in November 2022 marked a significant turning point for Ferrante and his team. Learning of the catastrophe while returning from the Solana Conference in Lisbon, they found themselves in what Ferrante describes as "cockroach mode" - focused solely on survival and maintaining the core team.

This period of intense stress and uncertainty lasted until the launch of Mad Lads about six months later. Ferrante reflects on this time, saying, "It was really a defining moment, I think, for us, and honestly just for a ton of people in the industry. And it was really about just staying alive."

Pivoting to a Centralized Exchange

In the aftermath of the FTX collapse and the subsequent instability in the traditional banking system, Ferrante and his team reassessed their position in the market. They observed a trend of new exchanges being started and realized that their expertise in engineering, product development, and marketing could be applied to this space.

However, Ferrante recognized a critical gap in their knowledge: compliance and international law. He states, "The things that I cannot do that I know nothing about is compliance. It's international law. It's the crazy complexity that is involved with building one of these financial institutions, not just in the US, but all around the world."

This realization led to a partnership with Ken, an expert in compliance and regulatory matters. Together, they saw an opportunity to leverage the Backpack brand and community, combined with Ken's compliance expertise, to build a centralized exchange that could meet the stringent requirements of the post-FTX era.

The Architecture of Backpack Exchange

Backpack Exchange is designed with a focus on transparency, security, and regulatory compliance. Ferrante describes the exchange as running its own "mini private blockchain" that combines traditional financial systems with cutting-edge blockchain technology.

The exchange utilizes state machine replication and multiple validators to ensure there is no single point of failure. Ferrante explains, "We basically have these different validators that, you know, independent instances of the exchange that all run in parallel. You can imagine all three of us were running our own versions of the exchange where not only do we have computational integrity guarantees on the execution, but also all the validators control the custody solution as well."

This architecture provides a high level of security and transparency. If any validator is compromised, the discrepancy can be detected and malicious actions prevented. Every transaction in the system is authenticated and signed with an ED25519 key pair, creating a globally ordered, linear authenticated log of messages that are archived and replayable.

Proof of Reserves and Transparency

One of the most innovative features of Backpack Exchange is its approach to proof of reserves. Ferrante and his team are working with Ottersec, a leading security audit firm in the Solana ecosystem, to develop a system of zero-knowledge proofs for reserves.

The goal is to provide daily proof of reserves that users can easily verify. Ferrante envisions a system where users can "go into a webpage, look at like a calendar UI, if you will, and just see all of my balances for every single snapshot where each snapshot, each proof is attested to on the blockchain every single day."

This level of transparency goes beyond what most exchanges currently offer, allowing users to independently verify the exchange's solvency and the safety of their funds.

The Role of Centralized Exchanges in the Crypto Ecosystem

Ferrante sees centralized exchanges like Backpack as playing a crucial role in bridging the gap between traditional finance and the crypto world. He describes exchanges as "an auxiliary service to the L1" and "this gateway or this bridge from the traditional financial system into the parallel system."

The primary function of these exchanges, in Ferrante's view, is to provide a compliant and efficient on-ramp for users to convert fiat currency into cryptocurrencies. He states, "If we do nothing but make it really easy and fast and cheap to convert any fiat currency anywhere in the world into your favorite gas token to get that into your wallet and we do that as cheaply as fast as possible, then we've done our job pretty well."

Compliance and Global Reach

One of the key challenges in building a global cryptocurrency exchange is navigating the complex landscape of international regulations and compliance requirements. Ferrante emphasizes the importance of this aspect, noting that without a strong compliance foundation, exchanges struggle to provide efficient and cost-effective services.

He points out, "Not to pick on anybody in particular, but like, it's not like, you know, we should not be charging users like the fees that are, you know, that some of these products are charging, right? And it's because they don't have that piece."

Backpack Exchange aims to solve this problem by building a robust compliance infrastructure from the ground up, enabling them to offer competitive fees and seamless international transactions.

The Integration of Wallet and Exchange

One of the unique aspects of Backpack's approach is the tight integration between their wallet and exchange services. Ferrante describes the user experience as seamless, with the exchange UX being the same as the self-custodial wallet UX.

This integration allows users to move easily between self-custody and the centralized exchange, providing a more fluid and user-friendly experience than traditional siloed approaches. Ferrante sees this as a key differentiator in the market, stating, "It's really making it seamless to go back and forth between those two worlds."

The Future of Blockchain Ecosystems

Ferrante shares his vision for the future of blockchain ecosystems, predicting that there will be "a small number of very high valuable of high value general execution layers" such as Solana and Ethereum, alongside a larger number of application-specific chains or "app chains."

He sees this bifurcation as a natural evolution of the space, with general-purpose chains providing the maximum amount of shared state and atomic composability, while app-specific chains cater to particular use cases or scale requirements.

XNFTs: Tokenized Applications

XNFTs, or executable NFTs, represent a novel approach to application distribution and tokenization. Ferrante explains that XNFTs solve two primary problems: the need for decentralized front-ends and the ability to create token-gated applications.

For decentralized applications like Uniswap, XNFTs provide a way to tokenize and distribute the front-end in a decentralized manner, ensuring that no single entity can take down the application. For projects like Mad Lads, XNFTs enable the creation of "bearer apps" that are tied directly to the ownership of the NFT, allowing for innovative loyalty and engagement mechanisms.

Challenges and Opportunities in XNFTs

While XNFTs offer exciting possibilities, Ferrante acknowledges that there are challenges to widespread adoption. The first is the technical barrier for creators who may not have the engineering skills to build XNFTs. The second is the need for a robust distribution platform to create network effects.

Despite these challenges, Ferrante sees significant potential in XNFTs, particularly in areas like decentralized front-ends and bearer programmability. He envisions future use cases such as airdropping programmable applications to specific NFT holders or communities, opening up new possibilities for targeted engagement and rewards systems.

The Importance of Action and Execution

When asked about advice for aspiring founders, Ferrante emphasizes the importance of taking action. He recalls advice he heard, possibly from Brian Armstrong of Coinbase, encouraging people to "just go do stuff." Ferrante explains, "It doesn't matter what it is just go do it because action just like provides information and when you get more information you can get more inside and do more interesting things."

This philosophy of learning through doing has been a driving force behind Ferrante's success. He notes that many of their projects, including the wallet, XNFTs, and even the exchange, grew out of active engagement with the community and the market.

The Influence of Gaming on Crypto Innovation

Ferrante draws interesting parallels between his experience with massively multiplayer online games (MMOs) like World of Warcraft and the crypto space. He notes that the social aspects of MMOs, such as creating online communities and forming bonds with people around the world, are very similar to what's happening in crypto communities and NFT projects.

This connection between gaming and crypto is not unique to Ferrante. Many innovators in the space have backgrounds in online gaming, which has helped them grasp concepts like digital ownership, virtual economies, and online communities more quickly.

The Launch of Backpack Exchange

As the interview concludes, Ferrante reveals that Backpack Exchange is set to launch imminently, with the first markets expected to be listed within a week of the interview. This announcement marks a significant milestone for the team and the broader Solana ecosystem.

The launch of Backpack Exchange represents more than just a new trading platform; it symbolizes a rebirth and evolution of the crypto exchange landscape in the wake of the FTX collapse. By combining robust engineering, innovative product design, and stringent compliance measures, Backpack Exchange aims to set a new standard for centralized exchanges in the crypto space.

The Broader Impact on the Solana Ecosystem

While Ferrante and his team are building Backpack Exchange to serve the broader crypto community, their roots in and commitment to the Solana ecosystem are clear. The exchange is poised to provide much-needed fiat on-ramps and liquidity to Solana, addressing one of the network's persistent challenges.

Ferrante notes that many existing exchanges have tended to "fade" Solana, treating it as a second-class citizen in terms of listings and public sentiment. Backpack Exchange aims to change this narrative, leveraging its deep understanding of Solana's technology and community to provide better support for the ecosystem.

A Multi-Chain Future

Despite his strong ties to Solana, Ferrante maintains a pragmatic and open-minded approach to blockchain ecosystems. He acknowledges the importance of Ethereum and expresses a desire to expand Backpack's services to include Ethereum in the future.

This multi-chain vision aligns with Ferrante's belief that maximalism is counterproductive. He states, "I think it would be a disservice to Solana to ever be a maximalist. I think the reason why I worked on Solana in the first place is because I cared about other blockchains."
