CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built on a foundation of battle-tested security and gas efficiency.
- Full Lifecycle Development: From specification and
Hardhat/Foundrytesting to mainnet deployment and upgrade management via Transparent Proxy Patterns. - Security-First Approach: Every contract undergoes manual review, static analysis with
Slither/MythX, and test coverage exceeding 95%. - Protocol Integration: Seamless compatibility with
ERC-20,ERC-721,ERC-1155, and custom standards for DeFi, NFTs, and DAOs.
We deliver audited, production-grade code in 2-4 weeks, enabling you to launch with confidence and avoid costly vulnerabilities.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Every contract is built with security-first principles, leveraging battle-tested libraries like OpenZeppelin and undergoing rigorous internal audits.
- Token Systems:
ERC-20,ERC-721,ERC-1155, andSPLtokens with custom minting, vesting, and governance logic. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield optimizers with gas-efficient math.
- Enterprise Logic: Multi-signature wallets, access control, and upgradeable proxy patterns for future-proofing.
We deliver audit-ready code in 2-4 weeks, reducing your time-to-market and technical risk.

Frequently Asked Questions
Get specific answers about our development process, timelines, and security for building a custom reputation system on NEAR.
A sharded reputation engine is a decentralized system that calculates and stores user reputation scores (e.g., for DeFi, social, or gaming) across multiple parallel shards. We build on NEAR Protocol because its Nightshade sharding provides linear scalability, sub-2-second finality, and predictable low fees—essential for real-time reputation updates across millions of users without congestion or high costs.
