We architect and deploy custom smart contracts that form the core logic of your dApp. Our development process is built on security-first principles, utilizing battle-tested patterns from OpenZeppelin and rigorous internal audits to mitigate risks before deployment.
NEAR Protocol Transaction Privacy Integration
Custom Smart Contract Development
Production-ready smart contracts built for security, scalability, and long-term maintainability.
From tokenomics to complex DeFi logic, we translate your business requirements into efficient, gas-optimized Solidity or Rust (
Solana) code.
- End-to-End Development: Full lifecycle support from design and
ERC-20/ERC-721implementation to deployment and verification on mainnet. - Security & Audits: Proactive vulnerability scanning and preparation for third-party audits from firms like CertiK or Quantstamp.
- Gas Optimization: Code engineered for minimum transaction costs and maximum user efficiency.
- Upgradeability Patterns: Implementation of secure proxy patterns (
TransparentProxy,UUPS) for future-proof, non-breaking upgrades.
Our Privacy Integration Capabilities
We deliver production-ready, audited privacy modules that integrate seamlessly with your NEAR Protocol application, ensuring compliance and user trust without compromising performance.
Zero-Knowledge Transaction Mixing
Integrate ZK-SNARK-based mixers for private token transfers. Our modules obfuscate sender, receiver, and amount on-chain, providing financial privacy for DeFi and payment dApps.
Confidential Smart Contract Execution
Enable private state and logic within your contracts using secure multi-party computation (MPC) frameworks. Keep business logic and sensitive data confidential while remaining verifiable.
Selective Disclosure & Compliance Gateways
Build compliant privacy with tools for authorized disclosure. Implement audit trails and regulatory reporting features that satisfy KYC/AML requirements while preserving default privacy.
Cross-Chain Privacy Bridges
Extend privacy to asset transfers between NEAR and other chains (Ethereum, Aurora). Our relayers and proving systems ensure private, trust-minimized cross-chain interactions.
Private NFT & Asset Management
Implement hidden ownership and private metadata for NFTs and SFTs. Enable confidential auctions, gated communities, and enterprise asset tracking on NEAR.
Why Integrate Transaction Privacy?
Privacy is no longer a niche feature but a core requirement for competitive DeFi, enterprise, and high-value applications. Our integration delivers compliant, on-chain privacy to protect your users and your business.
Protect User & Business Data
Shield transaction amounts, wallet balances, and counterparty relationships from public exposure. Prevent front-running, data harvesting, and competitive intelligence leaks that can harm your users and your market position.
Enable Compliant Enterprise Adoption
Deploy applications for regulated industries like finance and healthcare. Our privacy layer allows for selective disclosure to auditors and regulators without exposing all user data on a public ledger, meeting GDPR and other compliance frameworks.
Enhance DeFi & Trading Security
Eliminate MEV (Miner Extractable Value) exploitation and front-running for your DEX or trading platform. Private transactions prevent bots from seeing pending trades, ensuring fairer execution and better prices for your users.
Build Competitive Moats
Offer features that public-chain apps cannot. Enable confidential voting for DAOs, private payroll, and undisclosed OTC deals. Privacy becomes a unique selling proposition that attracts high-value users and institutional clients.
Future-Proof Your Application
Privacy-focused regulations are emerging globally. Proactively integrating privacy safeguards your application from future legal challenges and costly refactoring. Build with the next regulatory landscape in mind.
Maintain NEAR's Performance
Our integration uses zero-knowledge proofs optimized for NEAR's Nightshade sharding. Achieve transaction privacy without sacrificing the network's sub-2-second finality and low (<$0.01) transaction costs.

Our Delivery Process
A structured, four-phase engagement model designed to deliver production-ready NEAR privacy solutions with zero surprises. We focus on clear milestones, transparent communication, and guaranteed outcomes.
Phase 1: Discovery & Architecture
We conduct a technical deep-dive to define your privacy requirements, threat model, and integration scope. Deliverables include a detailed technical specification, architecture diagram, and a fixed-price project plan.
Phase 2: Core Module Development
Our engineers build and unit-test the core privacy modules—zk-SNARK circuits, state management, and on-chain verifiers—using battle-tested libraries like near-sdk-rs and circom. All code follows NEAR's security best practices.
Phase 3: Integration & Auditing
We integrate the privacy layer with your existing dApp smart contracts and frontend. The complete system undergoes rigorous internal review and a formal security audit by our partners before staging deployment.
Phase 4: Deployment & Handoff
We manage the mainnet deployment, conduct final load testing, and provide comprehensive documentation and developer training. The process concludes with a full code and operational handoff to your team.

Frequently Asked Questions
Get clear answers about integrating advanced transaction privacy into your NEAR-based application.
A standard integration of a privacy layer like Nightfall or ZK-based solutions takes 3-6 weeks from kickoff to mainnet deployment. This includes architecture design, smart contract development, frontend integration, security audit review, and deployment. Complex protocols with custom logic may extend to 8-10 weeks. We provide a detailed project plan within the first week.
