The Future is Peer-to-Peer
The crypto market is maturing beyond centralized giants. Users now demand greater control, transparency, and security over their assets. A Peer-to-Peer (P2P) exchange model directly answers this call, eliminating intermediaries and creating a trustless environment for direct trade. However, launching a successful P2P platform is a complex challenge, requiring deep expertise in blockchain security, smart contract engineering, and regulatory compliance. This is where we come in. Errna provides the end-to-end expertise to transform your vision for a decentralized marketplace into a secure, scalable, and user-centric reality, ensuring you capture your share of the future of finance.

Real-World P2P Exchange Success Stories
AfriPay: Revolutionizing Remittance in Africa
Industry: FinTech & Remittance
Client Overview: A FinTech startup aiming to disrupt the high-fee remittance market in several African countries. They needed a reliable, low-cost way for users to send and receive money across borders using stablecoins and local fiat currencies.
The Problem
Traditional remittance channels were slow, expensive (often with fees exceeding 10%), and lacked transparency. The client needed a P2P platform that was secure, easy to use on mobile devices with limited connectivity, and could handle multiple local fiat currencies against a stablecoin like USDT.
Key Challenges
- Integrating diverse and often fragmented local payment methods.
- Building a highly secure escrow system to prevent fraud in a low-trust environment.
- Ensuring the platform was lightweight and performed well on low-end smartphones.
- Navigating the complex and varied regulatory requirements across multiple countries.
Our Solution
We developed a custom, mobile-first P2P exchange focused on user experience and security. Our solution included:
- A smart contract-based escrow system on a low-fee blockchain (BSC) to minimize transaction costs.
- Integration with over 15 local mobile money and bank transfer APIs.
- A lightweight progressive web app (PWA) that worked seamlessly on any device.
- A robust admin panel with tiered KYC/AML levels to ensure regulatory compliance.
VaultX: A Private Exchange for High-Value OTC Trades
Industry: Investment & Asset Management
Client Overview: A US-based investment group specializing in digital assets. They needed a private, highly secure platform to facilitate over-the-counter (OTC) trades of large blocks of cryptocurrency for their institutional and high-net-worth clients, avoiding the price slippage and public exposure of traditional exchanges.
The Problem
Executing large crypto trades on public exchanges is risky and inefficient. The client required a P2P platform that offered privacy, guaranteed settlement, and robust security features to handle transactions often worth millions of dollars.
Key Challenges
- Implementing multi-signature and time-locked escrow for maximum security.
- Ensuring strict privacy and data protection for all participants.
- Building a compliant platform with full audit trails for institutional reporting.
- Creating a simple, professional interface for non-technical, high-profile clients.
Our Solution
We engineered a private, invitation-only P2P trading platform with a focus on security and compliance. Key features included:
- An Ethereum-based smart contract with multi-sig controls, requiring approvals from buyer, seller, and an arbiter.
- End-to-end encrypted communication and data storage.
- A comprehensive admin dashboard for managing users and generating detailed transaction reports.
- Integration with institutional-grade custody solutions for secure asset management.
Marketplace Crypto Integration
Industry: E-commerce & Retail
Client Overview: An established online marketplace for rare collectibles wanted to tap into the crypto-native audience by accepting cryptocurrency payments. They needed a solution that would protect their merchants from price volatility while offering buyers the flexibility to pay with digital assets.
The Problem
Directly accepting crypto payments was risky due to price fluctuations. The client needed a system where buyers could pay in crypto, but merchants would receive the exact fiat value of the sale at the time of purchase, eliminating volatility risk.
Key Challenges
- Ensuring instant and accurate price quoting for various cryptocurrencies.
- Building a seamless user experience that integrated into the existing checkout process.
- Creating a backend system to manage the crypto-to-fiat conversion for merchants.
- Guaranteeing the security of the payment process from end to end.
Our Solution
We developed a unique P2P payment module that integrated directly into their e-commerce platform. The system worked as follows:
- When a buyer chose to pay with crypto, a P2P order was created on the backend.
- The system locked the crypto in a smart contract escrow and simultaneously found a liquidity provider to purchase it for fiat.
- The fiat amount was instantly credited to the merchant's account, and the crypto was transferred to the liquidity provider.
- The entire process was automated and took less than a minute to complete.
