Privacy Wallet SDK Development | Chainscore Labs

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your dApp.

We deliver audit-ready smart contracts in Solidity and Rust, leveraging battle-tested patterns from OpenZeppelin and Anchor. Our focus is on security, gas efficiency, and upgradability from day one.

Full Lifecycle Development: From architecture and logic design to deployment and verification on EVM, Solana, or Starknet.
Security-First Approach: Every contract undergoes internal review against common vulnerabilities before external audit.
Measurable Outcomes: Reduce time-to-audit by 40%, achieve >99.9% uptime post-launch, and optimize for up to 30% lower gas costs.

We don't just write code; we build the foundational logic that secures your assets and enables trustless operations.

Our service is for teams that need reliable, scalable smart contract infrastructure without the overhead of building a specialized in-house team. We provide clear documentation, deployment scripts, and post-launch support.

ENGINEERED FOR PRODUCTION

Core Capabilities of Our Privacy SDKs

Our SDKs deliver battle-tested privacy primitives, enabling your team to build compliant, user-first wallets without the complexity of cryptographic implementation.

Zero-Knowledge Identity Proofs

Integrate zk-SNARKs and zk-STARKs for selective disclosure. Users prove age, residency, or accreditation without exposing raw data, enabling compliant DeFi and on-chain KYC.

EXPLORE

Transaction Privacy with Stealth Addresses

Generate unique, one-time addresses for every transaction to break on-chain linkability. Our SDK handles key derivation and management, simplifying integration for ERC-4337 and native wallets.

EXPLORE

Confidential Asset Transfers

Implement privacy pools and confidential transactions to obscure token amounts and types. Built with audited circuits for assets on Ethereum L2s and app-chains.

EXPLORE

Secure Multi-Party Computation (MPC) Vaults

Distribute private key shards across user devices and our secure cloud HSMs. Eliminates single points of failure while maintaining non-custodial guarantees and enabling instant recovery.

SOC 2 Type II

HSM Compliance

TSS/GG18

Protocol Standard

Regulatory Compliance Frameworks

Pre-built modules for Travel Rule (FATF 16), sanctions screening, and audit trails. Generate regulatory reports without compromising user privacy, designed for MiCA and global markets.

Privacy SDK Development: Common Questions

Get clear, specific answers about our process, security, timelines, and support for building privacy-first wallet SDKs.

A standard privacy SDK with core features like stealth addresses, transaction shielding, and key management takes 2-4 weeks from kickoff to production-ready delivery. Complex integrations with custom zero-knowledge circuits or multi-chain support can extend this to 6-8 weeks. We provide a detailed sprint-by-sprint roadmap during discovery.
