overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production by expert Solidity engineers.

We architect and deploy battle-tested smart contracts that form the foundation of your Web3 application. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and formal verification patterns to mitigate risk from day one.

Deliver a production-ready, audited contract suite in as little as 2-4 weeks.

Our full-cycle service includes:

  • Custom Logic: Tailored Solidity 0.8+/Vyper development for DeFi, NFTs, DAOs, and RWA.
  • Comprehensive Audits: Internal review + integration with top-tier third-party firms like CertiK or Quantstamp.
  • Gas Optimization: Code-level refinements to reduce user transaction costs by 15-40%.
  • Deployment & Verification: Full mainnet/testnet deployment with source code verification on Etherscan.

We provide ongoing maintenance and upgrade strategies, including transparent proxy patterns and robust governance modules, ensuring your protocol remains secure and adaptable post-launch.

End-to-end blockchain solutions from protocol design to production deployment.

We architect and build custom Layer 1/Layer 2 chains and private consortium networks tailored to your specific transaction volume, privacy, and governance needs. Our full-stack development delivers a production-ready blockchain in 8-12 weeks.

From a bespoke EVM-compatible chain for a DeFi protocol to a permissioned Hyperledger Fabric network for enterprise asset tracking, we handle the entire lifecycle.

  • Core Protocol Development: Consensus mechanisms (PoS, PoA), tokenomics, and governance models.
  • Node Infrastructure: Deployment, orchestration, and monitoring of validator/peer nodes.
  • Interoperability: Secure bridges and cross-chain communication layers using Wormhole or Axelar.
  • DevOps & Tooling: RPC endpoints, block explorers, and wallet integrations for your ecosystem.
Institutional NFT Custody

Frequently Asked Questions

Answers to common technical and operational questions about integrating secure, compliant NFT custody for your institution.

A standard integration with our custody SDK and APIs takes 2-4 weeks from kickoff to production deployment. This includes environment setup, smart contract whitelisting, multi-signature wallet configuration, and compliance rule definition. Complex requirements like custom settlement logic or support for novel token standards (ERC-6551, ERC-404) may extend the timeline, which we scope and quote for upfront.
