CORE SERVICE
Smart Contract Development
Secure, audited smart contract systems built for production at scale.
- Production-Ready Code: Built with
Solidity 0.8+orRust (for Solana), following industry standards likeERC-20,ERC-721, andERC-1155. - Full Lifecycle Support: From initial architecture and gas optimization to deployment, verification on Etherscan/Solscan, and post-launch monitoring.
- Security as Standard: Every contract undergoes multi-stage review and is prepared for third-party audits from firms like
CertiKorQuantstamp.
Deliver a secure, gas-efficient, and maintainable smart contract foundation in as little as 4-6 weeks for an MVP.

PROVEN METHODOLOGY
Our Delivery Process
A structured, four-phase approach designed to deliver secure, interoperable SBT protocols with predictable timelines and clear milestones.
01
Discovery & Architecture Design
We conduct a deep technical workshop to define your SBT's purpose, target chains (EVM, Cosmos, Solana), and interoperability requirements. Deliverables include a detailed technical specification and a cross-chain architecture diagram.
1-2 weeks
Duration
100%
Specification Clarity
02
Smart Contract Development & Auditing
Our team builds your core SBT logic using Solidity, Rust, or CosmWasm, implementing standards like ERC-721/1155 or CW-721. All code undergoes internal review and is prepared for a formal security audit by a third-party firm.
3-5 weeks
Development Cycle

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the backbone of your Web3 product. Our development process ensures security-first design, gas optimization, and audit readiness from day one.
- Token Standards:
ERC-20,ERC-721,ERC-1155, and custom implementations. - DeFi Protocols: Automated market makers, lending/borrowing pools, staking contracts.
- Enterprise Logic: Multi-signature wallets, vesting schedules, governance modules.
- Security: Built with
OpenZeppelinlibraries and formal verification patterns.
We deliver fully tested, documented, and deployable contracts in 2-4 weeks, not months.
Our engineers specialize in Solidity 0.8+ and Vyper, implementing upgradeable proxy patterns (UUPS/Transparent) for future-proofing. Every contract undergoes internal review against common vulnerabilities before external audit.
