Private Payment Messaging Layer Development

We design and implement secure, off-chain messaging layers for DeFi and payment protocols. Our solutions carry encrypted transaction details, settlement instructions, and compliance data without exposing sensitive information on-chain.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by experts for DeFi, NFTs, and enterprise applications.

We deliver audit-ready code from day one, built on Solidity 0.8+ with OpenZeppelin standards. Our focus is on security-first development and gas optimization to ensure your protocol is both safe and cost-effective to run.

  • Custom Logic: Tailored ERC-20, ERC-721, and complex DeFi primitives like AMMs and lending pools.
  • Full Lifecycle: From architecture and development to deployment, verification, and ongoing maintenance.
  • Proven Security: Rigorous internal review using static analysis and formal verification patterns before external audit.

Reduce your time-to-market with a 2-4 week MVP delivery cycle, backed by our team of protocol specialists.

ENTERPRISE-GRADE INFRASTRUCTURE

Core Capabilities of Our Messaging Layer

Our private payment messaging layer delivers the foundational infrastructure for secure, compliant, and scalable financial transactions on-chain. We provide the tools to build, not just the promise.

03

Multi-Chain & Multi-Asset Support

Native support for EVM chains (Ethereum, Polygon, Arbitrum) and assets (ERC-20, ERC-721). Our abstracted protocol layer future-proofs your application, allowing seamless expansion to new networks and token standards without core re-engineering.

04

High-Availability Relay Network

Fault-tolerant, globally distributed node network ensures message delivery with 99.9% uptime SLA. Implements automatic failover and redundant message queuing to guarantee transaction integrity even during partial network outages.

DELIVERABLES & GUARANTEES

Business Outcomes for Your Protocol

We architect and deliver a production-ready private payment messaging layer with measurable performance and security guarantees, accelerating your time-to-market and reducing operational risk.

01

Zero-Knowledge Transaction Privacy

Implement zk-SNARKs or zk-STARKs to enable fully private on-chain payments. We deliver audited circuits that conceal sender, receiver, and amount while maintaining public verifiability, ensuring your protocol meets strict compliance and user privacy demands.

02

Secure Multi-Party Computation (MPC) Relayers

Deploy a decentralized, fault-tolerant network of MPC nodes to privately compute and relay payment intents. Our architecture eliminates single points of failure and ensures message integrity, providing a robust backbone for your payment layer.

Cross-Chain Messaging Bridge

Build a secure, non-custodial bridge for private payment messages across Ethereum, Polygon, and other EVM chains. We use LayerZero or Axelar for verified message passing, enabling seamless private transactions in your multi-chain ecosystem.

Regulatory-Compliant Audit Trail

Engineer a selective disclosure system using zero-knowledge proofs. Authorized entities (e.g., auditors, regulators) can verify transaction legitimacy without exposing private data, future-proofing your protocol against evolving compliance requirements.

A PROVEN METHODOLOGY

Our Development & Integration Process

We deliver your private payment messaging layer from concept to production with a structured, transparent process designed for security, speed, and seamless integration.

01

Architecture & Protocol Design

We design a custom architecture based on your specific use case, selecting and extending the optimal protocol (e.g., ERC-4337, zk-SNARKs, or custom state channels) to ensure privacy and scalability from the ground up.

Private Payment Messaging

Frequently Asked Questions

Get clear answers on our development process, security, and timelines for building a secure private payment messaging layer.

A standard deployment for a custom private payment messaging layer takes 4-8 weeks. This includes the design of the cryptographic protocol, smart contract development, integration with your existing payment rails, and a full security audit. For more complex requirements like cross-chain support or advanced compliance features, the timeline extends to 10-12 weeks. We provide a detailed project plan within the first week of engagement.
