CORE SERVICES
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance logic. - DeFi Protocols: Automated market makers (AMMs), lending/borrowing pools, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control systems, and verifiable on-chain records.
- Full Audit Support: Deliverables include a formal verification report and a deployment-ready package.
From initial concept to mainnet launch, we ensure your contracts are gas-optimized, upgradeable, and secure, reducing time-to-market by 60% versus in-house development.

METHODOLOGY
Our Delivery Process
A structured, four-phase engagement designed for rapid, secure, and production-ready delivery of your Solana wallet biometric security system.
01
Architecture & Threat Modeling
We begin with a comprehensive security-first design. Our team maps your wallet's data flows, identifies attack vectors, and defines the biometric authentication architecture (on-device vs. server-side) to ensure a robust foundation.
1-2 weeks
Design Phase
NIST 800-63B
Compliance
02
Secure Rust Development & Integration
Our Solana experts implement the biometric module in Rust, integrating with solana-web3.js and native mobile SDKs (iOS Face ID/Touch ID, Android BiometricPrompt). We enforce memory safety and zero-knowledge principles for key handling.

Frequently Asked Questions
Get clear, technical answers to common questions about our biometric security implementation for Solana wallets.
A production-ready, audited wallet with core biometric features typically takes 4-6 weeks from kickoff to mainnet deployment. This includes architecture, Rust development on Solana's Anchor framework, biometric SDK integration (Face ID/Touch ID, Android BiometricPrompt), security audits, and deployment support. Complex features like multi-signature support or custom transaction logic can extend this timeline, which we scope and quote upfront.
