More than $2 billion has been lost to blockchain bridge exploits over the years, turning interoperability into one of the industry’s most difficult infrastructure problems. Moving assets and information between blockchains is essential to the idea of a multi-chain ecosystem, but the systems responsible for doing it have repeatedly become targets for attackers.
Polytope Labs entered this market with a different approach. Founded by Nigerian engineers Seun Lanlege and David Salami, the company has spent years researching cryptographic systems designed to let blockchains communicate without depending on trusted intermediaries. Its work has produced Hyperbridge, a cross-chain interoperability protocol, and more recently HyperFX, an on-chain foreign exchange platform built on the same infrastructure.
The company is now trying to take that infrastructure beyond the crypto-native market. Its latest product, HyperFX, targets a more familiar problem for African businesses: moving money across currencies and borders without forcing fintechs to keep large amounts of capital sitting idle in different markets.
How Polytope Labs started
Polytope Labs was founded in 2023 by Lanlege and Salami, both of whom had already spent years working on blockchain infrastructure. Lanlege previously worked at Parity Technologies, where he contributed to projects connected to Ethereum, Substrate and Polkadot, before joining Composable Finance and working on interoperability between Polkadot and Cosmos. Salami also worked at Composable Finance and contributed to cross-chain infrastructure.
Their experience shaped the company’s original focus. Rather than building another consumer-facing crypto application, Polytope Labs wanted to work on the underlying infrastructure that allows different blockchain networks to communicate.
That distinction matters because blockchains were not designed as one connected system. Ethereum, Polkadot, Base, Arbitrum and other networks maintain their own environments, rules and data. For applications to move assets or read information across those networks, another layer of infrastructure is needed.
Polytope Labs calls itself a cryptographic systems studio. Its current website says it researches and builds proof-driven interoperability systems that allow applications to move state, assets and messages across chains without trusted middlemen.
The problem Polytope is trying to solve
Blockchain interoperability has always come with a difficult trade-off.
Users want to move assets between networks, but the bridge responsible for that transfer needs a way to verify that something happened on one blockchain before allowing another blockchain to recognise it. Many bridge designs have relied on multisignature wallets, external validators or other systems that introduce additional trust assumptions.
Those points of failure have been exploited repeatedly. Wormhole lost $320 million in 2022, Ronin suffered a more than $600 million theft, and other bridge-related attacks have added hundreds of millions of dollars to the industry’s losses.
Polytope’s answer is to use cryptographic proofs to verify information between networks. Instead of asking users to trust a small group of actors to confirm that a transaction happened, the system is designed to verify blockchain state using proofs.
This is the thinking behind Hyperbridge.
Hyperbridge became its flagship product
Hyperbridge is Polytope Labs’ interoperability protocol and the product that put the company on the map.
The protocol is designed to allow applications to send messages, transfer assets and verify state across different blockchain networks. Polytope describes it as a coprocessor for secure cross-chain messaging, consensus proofs and state verification.
Hyperbridge’s development also attracted funding from the wider Polkadot ecosystem. Its seed round raised about $2.5 million, while a subsequent Initial Relayer Offering raised another $2.8 million, bringing total funding reported by Hyperbridge to about $5.65 million. The seed round was led by the Polkadot Ecosystem Fund, a joint initiative involving the Web3 Foundation and Scytale Digital.
That distinction is important: the $5.65 million figure is associated with Hyperbridge, Polytope Labs’ flagship protocol, rather than a conventional venture round into Polytope Labs itself.
By 2025, Hyperbridge was supporting interoperability across more than 12 blockchain networks, according to TechCabal, including Ethereum, Arbitrum, Base, BNB Chain and Polkadot.
From interoperability to financial infrastructure
Polytope’s work has increasingly moved closer to financial applications.
In March 2026, it was reported that the company was exploring an on-chain stablecoin infrastructure designed for Nigerian fintechs and remittance companies. The problem it identified was not simply moving money between blockchains but the amount of capital fintechs need to keep pre-funded in different countries to settle transactions.
Consider a remittance company sending money from the United Kingdom to Nigeria. For the Nigerian recipient to receive naira immediately, the fintech may need to maintain naira liquidity in advance.
That money is known as a float. For a growing fintech, maintaining large amounts of idle capital across several markets can become expensive and inefficient because the company has to fund liquidity before customers even initiate transactions.
Polytope’s proposed solution was to use stablecoins and on-demand liquidity to reduce the need for that pre-funded capital. The company has now taken that idea further with HyperFX.
HyperFX brings Polytope into foreign exchange
In July 2026, Polytope Labs launched HyperFX, an on-chain foreign exchange engine designed to let businesses swap currencies using stablecoins. The platform currently settles its naira leg through cNGN, a naira-backed stablecoin.
HyperFX is built on top of Hyperbridge. Polytope says Hyperbridge has moved more than $500 million across 15 or more connected chains using cryptographic proofs, although this remains a company-reported figure rather than an independently audited performance metric.
The product is aimed at businesses that already operate across borders. Fintechs can integrate HyperFX through an API, while remittance companies, payment platforms, wallets and other financial businesses can use its infrastructure to access stablecoin-based foreign exchange.
Polytope says HyperFX charges a flat 0.05% fee for swaps and aggregates liquidity from multiple providers. It also says liquidity providers can keep custody of their assets while making liquidity available when it is needed for trades.
The significance of HyperFX is that Polytope is no longer building only for blockchain developers. It is attempting to turn the infrastructure it developed for Web3 into a financial product that can address a problem faced by African fintech companies.
Why Nigeria is an important market
Nigeria provides a natural testing ground for this approach because foreign exchange remains a major challenge for businesses operating across borders.
The country’s FX market has long involved multiple channels, including banks, licensed operators and informal markets. For businesses that need to move money between naira and foreign currencies, the process can be costly and complicated.
HyperFX is designed to bring part of that process on-chain. Stablecoins act as the settlement assets while smart contracts execute the swaps.
The naira side of the system currently uses cNGN, a naira-backed stablecoin. HyperFX’s launch materials describe cNGN as designed for commercial use and say the platform was developed with regulatory considerations in mind. Those claims should be understood as statements from the companies involved rather than independent regulatory certification.
This gives Polytope an opportunity to test whether infrastructure originally designed for blockchain interoperability can solve a problem outside traditional Web3 applications.
The setback Hyperbridge faced
Polytope’s progress has not been without problems.On April 13, 2026, Hyperbridge suffered an exploit involving its MMR verifier. According to the project’s post-mortem, an attacker forged a proof and used it to drain the Token Gateway contract. The project said the incident was isolated to that gateway.
The incident is particularly significant because security is central to Hyperbridge’s value proposition. The protocol was built around cryptographic verification and reducing trust assumptions in cross-chain infrastructure, so a vulnerability in one of its verification components represented a serious test of that approach.
Polytope did not simply patch the system and resume operations. Hyperbridge said it used the downtime to redesign parts of its architecture, remove what it described as centralised “training wheels” and strengthen the protocol before relaunching. The protocol resumed bridging in June 2026.
Hyperbridge subsequently expanded its interoperability infrastructure again. In July, it went live on Polkadot Hub mainnet with connections to more than 14 blockchain networks, according to the Polkadot ecosystem’s published update.
The exploit does not erase the technical work Polytope has done, but it does provide an important reality check. In blockchain infrastructure, security claims are ultimately tested by what happens when the system is attacked.
Building beyond Hyperbridge
The launch of HyperFX suggests that Polytope’s ambitions are now broader than building a bridge.
Its current website lists two live products: Hyperbridge for verifiable interoperability and HyperFX for cross-chain finance. Behind them is a research layer focused on consensus proofs, state proofs and open infrastructure.
That structure gives the company a different business direction from many African crypto startups. Instead of building primarily around retail trading, wallets or consumer payments, Polytope is trying to commercialise the underlying infrastructure that allows different financial systems and blockchain networks to interact.
If it works as intended, a fintech could use Polytope’s infrastructure without needing to understand the cryptographic machinery underneath it. The company would simply integrate the API or SDK and use the FX functionality as part of its existing product.
That is a much bigger potential market than selling infrastructure only to blockchain-native developers.
What gives Polytope an advantage
Polytope’s biggest advantage is the technical background of its founders and the amount of time the company has spent on interoperability research.
Lanlege and Salami were working on cross-chain systems before interoperability became one of the industry’s most widely discussed infrastructure problems. Their previous work at Parity Technologies and Composable Finance gave them experience with some of the networks and protocols that Hyperbridge is designed to connect.
The company has also built its products around a specific technical thesis: blockchain communication should rely more heavily on cryptographic verification and less on trusted intermediaries.
That gives Polytope a coherent product story. Hyperbridge provides the interoperability layer, while HyperFX uses that layer for financial settlement.The challenge is turning that technical advantage into sustained commercial adoption.
The challenges ahead
Interoperability remains an extremely competitive part of blockchain infrastructure.
Polytope is competing indirectly with bridges, interoperability protocols and messaging systems that have already built relationships with major blockchain networks and developers. Winning technically is not enough; developers and financial institutions also need confidence that the infrastructure will remain secure, reliable and available over the long term.
The April exploit makes that challenge more visible. A protocol that handles financial transactions has little room for serious security failures, particularly when its core selling point is verifiability.
HyperFX also faces a separate challenge: liquidity.A foreign exchange platform needs enough liquidity to provide competitive rates and execute trades efficiently. Polytope is attempting to address this by aggregating liquidity providers and using on-chain infrastructure to make liquidity available when needed. But whether the model can attract enough volume and liquidity to compete with existing FX channels remains to be seen.
Regulation will matter too, particularly because HyperFX is moving into foreign exchange and stablecoin settlement. The company’s use of cNGN gives it a local settlement rail, but operating financial infrastructure at scale requires navigating the regulatory frameworks of every market where the product is used.
Where Polytope Labs is going
The direction of Polytope Labs is becoming clearer.The company began with research into blockchain interoperability and turned that work into Hyperbridge. It then took the same infrastructure and started applying it to a financial problem that African fintechs understand well: how to move money across borders without tying up too much capital in pre-funded accounts.
HyperFX is therefore more than a new product. It represents a shift in how Polytope is trying to commercialise its technology.The company is betting that interoperability will eventually become invisible infrastructure. Users may not care which blockchain processes a transaction, just as most internet users do not think about the underlying networking protocols when they send a message or open a website.
What comes next
The next phase will be less about proving that cross-chain infrastructure is possible and more about proving that it can support real economic activity.
Hyperbridge has already had to survive a major security incident, redesign parts of its architecture and return to mainnet. HyperFX now gives Polytope another test: whether infrastructure developed for Web3 can solve real problems for businesses moving money across African markets.
The company has technical credibility, experienced founders and a product that addresses a genuine infrastructure problem. But the difficult part is still ahead.
Polytope needs developers to build on Hyperbridge, financial companies to integrate HyperFX, liquidity providers to support the system and users to trust the infrastructure with real money.
If it succeeds, Polytope Labs could become one of the more unusual blockchain infrastructure companies to emerge from Nigeria , not because it built another crypto application, but because it is attempting to build the rails underneath applications that need different blockchains and financial systems to work together.
