CORE INFRASTRUCTURE
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 compliant asset management.
- Full Audit Trail: Every contract includes comprehensive documentation and passes third-party security audits before mainnet deployment.
We deliver battle-tested code that reduces your time-to-market from months to weeks while eliminating critical vulnerabilities.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your token, DeFi, or NFT project.
We architect and deploy custom smart contracts on Ethereum, Solana, and EVM-compatible L2s. Our process delivers audit-ready code in weeks, not months, using battle-tested patterns from OpenZeppelin and Solmate.
- Token Standards:
ERC-20,ERC-721,ERC-1155, andSPLwith custom minting, vesting, and governance logic. - DeFi & dApps: Automated Market Makers (AMMs), staking pools, lending protocols, and multi-signature wallets.
- Security First: Every contract undergoes internal review against common vulnerabilities before external audit.
We don't just write code; we deliver the foundational infrastructure your application needs to scale securely. Our contracts are built for gas efficiency and upgradeability from day one.
SSI Wallet Audits
Frequently Asked Questions
Get clear answers about our performance and security audit process for Self-Sovereign Identity (SSI) wallets. We provide transparency on methodology, timelines, and outcomes.
A comprehensive audit for a standard SSI wallet implementation takes 2-3 weeks. This includes a 1-week deep-dive security review, a 1-week performance and UX analysis, and a final week for report compilation and remediation guidance. Complex integrations (e.g., with enterprise IAM systems or custom credential schemas) may extend this by 1-2 weeks. We provide a detailed project plan within 48 hours of initial scoping.
