Blockchain infrastructure company, Polytope Labs, is planning to launch an on-chain stablecoin infrastructure for foreign exchange (FX) settlement, according to a leaked pitch deck obtained by Techpoint Africa.
The proposed system will be built on top of the company’s Intent Gateway, a component of its interoperability framework known as Hyperbridge, which is designed to enable fast and secure asset transfers across blockchain networks.
If successfully deployed, the product could offer fintech companies a new way to manage liquidity for cross-border transactions, addressing one of the most persistent operational challenges in emerging markets: the cost and complexity of FX settlement.
Polytope’s flagship protocol, Hyperbridge, has already processed approximately $500 million in cross-chain messages on mainnet, demonstrating early traction for its interoperability infrastructure.
The liquidity problem facing emerging market fintechs
According to Lanlege, co-founder of Polytope Labs, FX settlement in emerging markets remains expensive, slow, and structurally inefficient, particularly for companies operating across multiple currency corridors.
“FX settlement in emerging markets is expensive, slow, and inaccessible to the businesses that need it most,” Lanlege said.
At the heart of the issue is the pre-funding model, which requires fintech companies to maintain large currency balances in destination markets before transactions can be completed.
For example, when a customer in London sends $500 to Lagos, the receiving fintech must already have naira stored in a Nigerian bank account in order to disburse the funds instantly to the recipient.
These reserves, known as floats, must be constantly maintained to ensure payouts do not stall. If a float runs dry, transaction delays can occur, potentially eroding customer trust and damaging a fintech’s competitive position.
For early-stage startups, maintaining these floats often means locking up scarce venture capital in idle bank accounts rather than investing in product development or market expansion.
For larger payment companies, the challenge becomes even more complex. Firms operating across several corridors must maintain multiple currency balances simultaneously, exposing them to foreign exchange volatility.
Currency volatility adds further risk
Currency fluctuations can significantly amplify the cost of holding cross-border liquidity.
Between 2023 and early 2025, the Nigerian naira lost roughly 70 per cent of its value against the US dollar, highlighting the risks associated with maintaining naira-denominated reserves.
For fintechs holding local currency floats, such depreciation effectively erodes working capital, creating additional financial pressure in a market already characterised by thin margins.
Fintech companies also require reliable liquidity providers capable of converting stablecoins such as USDT or USDC into naira at competitive rates.
These relationships are typically managed manually, negotiated over extended periods, and require constant monitoring and rebalancing to ensure adequate liquidity across payment corridors.
Polytope’s on-demand liquidity model
Polytope Labs is proposing an alternative to the traditional pre-funded model by introducing on-demand liquidity matching through an intent-based network.
Instead of requiring fintechs to maintain large currency balances, the system would allow them to broadcast a stablecoin-to-fiat “swap intent” across a decentralised network of liquidity providers.
These providers would then compete in real time to fulfil the transaction, submitting bids to complete the exchange.
The approach aims to reduce the need for pre-funded accounts while improving transaction efficiency and pricing transparency.
However, whether such a system can operate reliably at scale remains an open question, particularly in markets where liquidity conditions are fragmented.
The role of cNGN in naira settlement
A critical component of Polytope’s proposed infrastructure is cNGN, a digital representation of the Nigerian naira designed for blockchain-based settlement.
Under the model described in the pitch deck, a transaction from a remittance platform such as LemFi could follow a multi-step process:
- USD is converted into USDT or USDC
- The stablecoin is then swapped for cNGN through the intent network
- The cNGN is redeemed 1:1 for fiat naira
- The naira is transferred into a Nigerian bank account
This process allows fintech platforms to process transactions internally using stablecoins while remaining compliant with regulatory frameworks governing local currency settlements.
By bridging stablecoins and fiat currencies through programmable infrastructure, Polytope aims to streamline backend settlement processes for cross-border payment providers.
Growing competition in stablecoin-powered payments
The move comes at a time when stablecoins are gaining increasing traction in global payments, particularly for cross-border transactions.
Several African fintech companies are already exploring similar infrastructure.
For instance, payment firms such as Flutterwave and Yellow Card have integrated with Circle’s stablecoin payment network, enabling settlement using USDC.
Polytope’s proposed infrastructure could offer a homegrown alternative for Nigerian fintechs, potentially reducing reliance on foreign-built settlement systems.
While the company has not disclosed which firms may be piloting the solution, the pitch deck suggests that the infrastructure is designed specifically for remittance companies, cross-border fintech platforms, and financial service providers operating in emerging markets.
Stablecoins move into mainstream finance
Interest in stablecoins is no longer limited to crypto-native startups.
Financial institutions, payment networks, and regulators are increasingly examining how stablecoin-based settlement systems could improve the efficiency of international payments.
If Polytope’s proposed platform gains adoption, it could position the company as a key infrastructure provider in the emerging stablecoin settlement ecosystem, particularly across Africa’s rapidly expanding fintech sector.
For Polytope Labs, the initiative represents a strategic expansion beyond interoperability technology into the broader financial infrastructure layer powering cross-border commerce.
Talking Points
It is interesting that Polytope Labs is exploring an on-chain stablecoin infrastructure for foreign exchange settlement, a move that directly addresses one of the most persistent challenges fintech companies face in emerging markets: liquidity management.
The current pre-funding model forces fintechs to maintain large currency floats across multiple markets, tying up capital that could otherwise be deployed into product development, expansion, or customer acquisition.
At Techparley, we see how solutions that reduce the need for pre-funded accounts could significantly improve the efficiency of cross-border payments, particularly for startups operating in volatile currency environments such as Nigeria.
The proposed intent-based liquidity model is particularly notable. By allowing liquidity providers to compete in real time to fulfil transactions, the system could potentially lower settlement costs and improve access to foreign exchange liquidity.
Another important dimension is the role of stablecoins in the settlement process. As interest in stablecoin-based payments continues to grow globally, infrastructure that bridges stablecoins with local fiat currencies could become a critical backbone for cross-border fintech operations.
As the stablecoin ecosystem continues to evolve, Polytope Labs’ initiative highlights how African blockchain startups are beginning to build foundational infrastructure for the future of digital finance. If successfully implemented, this could reshape how fintech companies manage cross-border settlements in emerging markets.
