Oluwaseun "Seun" Lanlege is the founder and CEO of Polytope Labs, a research and development company that created the Hyperbridge interoperability protocol. Prior to his entrepreneurial work, Lanlege was a core developer at Parity Technologies, where he contributed to the Polkadot and Substrate ecosystems, and also led research at Composable Finance. ^{[1] [2]}​

Often referring to himself as a "web3 philosopher," Lanlege is a vocal advocate for using decentralized technology to create financial freedom and circumvent traditional financial systems, particularly for individuals in developing nations. ^{[3] [4]}​

Education

Seun Lanlege attended the Federal University of Technology Akure, where he was enrolled in the Bachelor of Technology (BTech) program in Remote Sensing and Geosciences. His studies took place between 2014 and 2016. The academic program was not completed, and his enrollment ended after two years. ^[5]

Career

Early Career

Lanlege began his career in technology as a mobile and web developer, starting with PHP and C++ before focusing on Android development. ^{[5] [6]} His early roles included positions as a software engineer at the online travel agency Hotels.ng and as a mobile engineer at firms including Astract and TechAdvance. ^{[2] [6]} His first professional encounter with blockchain technology was in 2016 while working at ALAT by Wema, Nigeria's first fully digital bank, where he contributed to an internal consortium prototype for inter-bank settlements using Hyperledger Fabric. ^[2]​

Parity Technologies

Lanlege's career in the public blockchain space began after he made significant open-source contributions to the Rust ecosystem, particularly to a Rust implementation of Web3.js. ^[6] These contributions led to him being hired as a Core Developer at Parity Technologies, the blockchain infrastructure company founded by Ethereum co-founder Gavin Wood, around 2018-2019. ^{[4] [2]}​

During his tenure at Parity, which lasted until 2021, Lanlege worked on foundational Web3 projects, including:

• Substrate: A modular framework for building custom blockchains. He contributed to the FRAME runtime development environment.
• Polkadot: A multichain network protocol. He worked on its consensus mechanisms, including the GRANDPA finality gadget.
• He was also the primary maintainer of parity-db, a database used within the Parity ecosystem. This period of his career was defined by work on core infrastructure for the blockchain industry. ^[2]

Composable Finance

After leaving Parity Technologies, Lanlege joined Composable Finance in late 2021. In his role as Director of Engineering and Head of Research, he led the development team responsible for building Hyperspace, an implementation of the Inter-Blockchain Communication (IBC) protocol. This work successfully connected the Polkadot and Cosmos ecosystems, a notable achievement in cross-chain interoperability at the time. ^{[2] [4]}​

Polytope Labs and Hyperbridge

In early 2022, Lanlege founded Polytope Labs alongside co-founder David Salami. Polytope Labs is a research and development company focused on solving core challenges in Web3, particularly blockchain interoperability, scalability, and privacy. ^{[8] [6]} Lanlege has stated that he quit a role paying $400,000 per year to found the company and work full-time on its flagship project, Hyperbridge. ^[3]​

The lab also has a stated mission of developer education, aiming to train and onboard developers from the African continent into the Web3 space. ^[6]​

Hyperbridge

Hyperbridge is an interoperability protocol designed by Polytope Labs to enable secure, trust-minimized communication between heterogeneous blockchains. Lanlege describes it as an "interoperability coprocessor" that offloads complex cross-chain computations and verifications. ^[1] The project's concept originated at a Web3 Summit hackathon, where Lanlege and a collaborator won a prize for their initial idea. ^[3]​

Technology

Hyperbridge was created to address the security vulnerabilities of traditional cross-chain bridges, which often rely on multi-signature (multisig) schemes. Such schemes create a central point of failure, as demonstrated by bridge hacks that resulted in over $2 billion in losses in 2022 alone. ^{[7] [2]}​

Instead of trusted parties, Hyperbridge's security is based on cryptography. Its architecture includes:

• Zero-Knowledge Proofs (ZKPs): The protocol uses zk-SNARKs to generate compact, cryptographic proofs of state transitions on a source chain. These proofs can be verified efficiently on a destination chain without requiring the verifier to trust a third party or re-execute the entire transaction.
• Isomorphic State Proofs: This is a framework developed by Polytope Labs that allows different blockchain systems to verify each other's state changes directly.
• Relayer Network and Bidirectional Security: A decentralized network of relayers submits "finality proofs" (evidence that a transaction is irreversible) to the Hyperbridge verification chain. The protocol features a bidirectional feedback loop where Hyperbridge not only verifies proofs from other chains but also generates its own proofs that must be validated externally, creating a system based on "mathematical truth, not trust in a group of people."
• Polkadot Integration: To handle the high computational demands of proof verification, Hyperbridge rents processing power, or "Coretime," from the Polkadot network, leveraging its shared security model.

The core of the protocol is the Inter-chain State Machine Protocol (ISMP), a standardized messaging layer for cross-chain communication. ^{[9] [7] [6]}​

Views and Philosophy

Lanlege is a vocal proponent of using technology to achieve financial sovereignty. He has stated that his primary motivation for entering the Web3 space was to seek "financial freedom" and escape the limitations imposed by traditional financial systems on people in sub-Saharan Africa. ^[4]

"I've seen the damage that can be done by walling off people from the global financial systems and blockchains are critical to systematically dismantling these institutions. Greater financial freedom means prosperity for all, not just a few." ^[4]

He views secure blockchain interoperability as the "holy grail" and the "final boss-level problem" for Web3, believing a multi-chain future is necessary for the technology to scale globally. ^[5] He is also a strong advocate for open-source development, crediting his own contributions as the key to his career progression and frequently advises new developers to participate in open-source projects. ^[6]

Lanlege also uses his public platform to share opinions on the tech industry and geopolitics. In October 2025, he criticized the "Project/Product manager" role in tech companies, stating it was the responsibility of the technical lead. ^[3]

Notable Incidents

Conflict with LayerZero

On May 9, 2025, Lanlege publicly accused the competing interoperability protocol LayerZero of unethical business practices. The incident occurred after LayerZero announced a partnership for a bridging service also named "Hyperbridge." Lanlege claimed this was a deliberate attempt to co-opt his project's brand and damage its search engine optimization (SEO). He wrote on X (formerly Twitter):

"I have to say this is a whole new low and only shows desperation. You guys obviously can't compete on technology so you resort to poisoning our SEO? Masterful gambit honestly. But it won't save you." ^[3]

Public Profile and Misinformation

In late 2025, Lanlege and his co-founder David Salami were the subject of a viral skit that inaccurately portrayed them as splurging venture capital funds on luxury items. An article in Techpoint Africa later clarified that the skit was not factual. ^[7]​

Interviews

Entering Hyperbridge #01

This interview features Seun Lanlege, founder of Polytope Labs and contributor to the Hyperbridge project, speaking on the YouTube channel The Kus in an episode titled Behind the Code: Web3 Builders. The video premiered on August 31, 2024.

The discussion addresses interoperability as a structural requirement for blockchain systems operating across multiple networks. Lanlege describes Hyperbridge as a cross-chain communication protocol intended to enable interaction between blockchains while allowing each network to retain its own consensus mechanism. This design is contrasted with interoperability models that require participating chains to adopt a shared or external consensus layer.

According to Lanlege, Hyperbridge operates as a cryptoeconomic co-processor that aggregates and verifies cross-chain messages through cryptographic proofs. He outlines an approach focused on reducing the computational and economic cost of verification, particularly for EVM-based chains, by using compressed proofs while still relying on validator signatures and consensus data from source chains.

Security is a central topic throughout the interview. Lanlege refers to prior incidents involving cross-chain bridges and attributes many of these failures to architectural dependencies on centralized intermediaries or limited trust assumptions. In this context, Hyperbridge is presented as an alternative design that emphasizes message authentication through on-chain verification rather than external attestations.

The interview also situates Hyperbridge within a broader view of blockchain infrastructure. Lanlege characterizes blockchains as independent computing systems that require standardized methods of communication to function collectively. From this perspective, interoperability protocols are described as infrastructural components that facilitate coordination across distinct networks rather than as application-level features.

Governance is discussed as an additional area of interest. Lanlege references on-chain governance mechanisms and decentralized autonomous organizations as examples of how blockchain systems can encode decision-making processes. The conversation notes existing challenges related to participation incentives and governance dynamics, indicating that these systems remain subject to ongoing experimentation.

In summary, the interview documents Lanlege’s views on cross-chain communication, security considerations, and governance within multi-chain environments, using Hyperbridge as a case study for discussing current design approaches to blockchain interoperability. ^[11]

Building the Future of Blockchain #02

In an interview aired on the YouTube channel Mustard Insights on July 21, 2025, Seun Lanlege, co-founder of Polytope Labs, discussed his views on blockchain infrastructure, decentralized finance, and cross-chain communication.

Lanlege described blockchain technology as a decentralized computing system developed to address the double-spending problem through distributed verification mechanisms. In this context, blockchains were characterized not as general-purpose databases, but as systems designed to enable verifiable execution and state agreement without centralized control. Cryptocurrencies were presented as native digital assets operating within these systems, while decentralized finance was defined as a category of financial applications deployed directly on blockchain networks. Web3 was outlined as a model for internet services in which data and digital assets are managed through decentralized protocols rather than centralized platforms.

The interview addressed patterns of cryptocurrency adoption across different regions. According to Lanlege, usage has increased in countries experiencing inflation, foreign exchange restrictions, or limited access to international financial systems, with examples drawn from parts of the Global South. In these contexts, cryptocurrencies and stablecoins were described as tools for transacting value and accessing financial services outside traditional banking structures. He noted that in regions with established financial infrastructure, adoption tends to follow different usage patterns and motivations.

Interoperability between blockchain networks was identified as a recurring topic in the discussion. Lanlege characterized the blockchain ecosystem as composed of multiple independent networks with limited native communication. Cross-chain bridges were described as technical mechanisms that enable the transfer of assets and data between these networks. Within this framework, Hyperbridge was presented as Polytope Labs’ implementation of a multi-chain bridge, designed to operate through verifiable processes rather than custodial asset management.

The interview also examined common interpretations of blockchain technology. Lanlege stated that blockchains are frequently mischaracterized as efficient data storage systems, despite being optimized instead for verification and consensus. He further discussed long-term developments in digital finance, including the possibility that portions of national money supplies could be represented on public blockchains through tokenized instruments, with stablecoins functioning as intermediaries for accessing these systems. ^[10]
