EVM Mobile SDK Integration

overview

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. Our focus is on security-first development, gas optimization, and upgradeability patterns to protect assets and ensure long-term viability.

From token launches to complex DeFi protocols, we deliver battle-tested code that just works.

Security Audits: Every contract undergoes rigorous review using Slither and MythX, followed by a formal audit report.
Standard Compliance: Full support for ERC-20, ERC-721, ERC-1155, and custom standards with built-in compliance hooks.
Deployment & Verification: Full-stack deployment pipeline with on-chain verification and monitoring dashboards.

Get from spec to mainnet in as little as 3 weeks. We provide complete documentation and handoff for your team.
