EVM Frontend Compliance Gateway Development

Deploy a configurable, on-chain aware gateway for your dApp frontend. We build systems that enforce geoblocking, KYC prompts, and jurisdictional rules before wallet connection, specifically for Ethereum and EVM-compatible L2s.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts for DeFi, NFTs, and enterprise applications.

We deliver audited, gas-optimized smart contracts that power your core business logic. Our development process ensures security-first architecture and maintainable code from day one.

  • Custom Logic: Build on ERC-20, ERC-721, ERC-1155, or bespoke standards.
  • Full Audit Trail: Integrated security reviews using industry tools like Slither and MythX.
  • Deployment Ready: Contracts are packaged with deployment scripts, upgradeability patterns, and comprehensive documentation.

Reduce your time-to-market and technical risk with battle-tested development practices.

Our engineers specialize in Solidity 0.8+ and Vyper, implementing proven patterns from OpenZeppelin. We focus on delivering contracts that are:

  • Efficient: Minimize gas costs for end-users.
  • Secure: Mitigate common vulnerabilities like reentrancy and overflow.
  • Upgradable: Designed with proxy patterns for future iterations without migration.

Our Delivery Methodology

We deliver production-ready EVM Frontend Compliance Gateways through a structured, transparent process designed for technical leaders. Our methodology ensures security, speed, and seamless integration with your existing stack.

01

Architecture & Threat Modeling

We begin with a comprehensive security-first design, mapping data flows and attack vectors. This includes defining compliance rule logic, wallet interaction patterns, and integration points with your backend APIs and smart contracts.

Frequently Asked Questions

Get clear answers on how we build secure, compliant, and scalable blockchain interfaces for regulated applications.

An EVM Frontend Compliance Gateway is a secure middleware layer that sits between your DApp's user interface and the blockchain. It enforces regulatory and business logic—like KYC/AML checks, transaction screening, and jurisdictional rules—before a transaction is signed and submitted. You need one to operate legally in regulated markets, protect your platform from illicit activity, and reduce legal liability, all while maintaining a seamless user experience.
