CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
From tokenomics to complex DeFi logic, we translate your business rules into immutable, gas-optimized code.
- Token Standards:
ERC-20,ERC-721,ERC-1155,SPLwith custom minting, vesting, and governance modules. - DeFi & DAOs: Automated market makers, staking pools, multi-sig treasuries, and voting systems.
- Security Guarantee: All contracts undergo manual review, automated analysis with
Slither/MythX, and a third-party audit roadmap. - Full Lifecycle: Development, testing on
Goerli/Devnet, mainnet deployment, and ongoing upgrade management via proxies.

Frequently Asked Questions
Get clear answers on how our automated tax reporting solution integrates with your Solana DeFi application.
Our integration follows a proven 4-step methodology: 1) API Connection: We securely connect to your protocol's on-chain data via RPC nodes. 2) Transaction Mapping: Our engine categorizes all DeFi interactions (swaps, staking, lending, liquidity provision). 3) Cost Basis Calculation: We apply specific identification (SpecID) and other accounting methods to track gains/losses. 4) Report Generation: Users receive formatted tax documents (Form 8949, Schedule D) via your app's UI. We handle the entire backend logic, requiring minimal frontend changes from your team.
