Cross-Chain Token-Gated Access Control

Engineer systems that allow token-based permissions (NFTs, SBTs, fungible tokens) held on one blockchain to govern access to resources, content, or functions on a completely separate, disconnected blockchain or Layer 2.

overview
CORE INFRASTRUCTURE

Smart Contract Development

Secure, audited smart contracts that power your Web3 application's core logic.

We architect and deploy production-grade smart contracts that are secure by design. Every contract undergoes a multi-stage audit process, including automated analysis, manual review, and formal verification for critical logic.

  • Custom Development: Tailored Solidity/Rust contracts for DeFi protocols, NFT marketplaces, and DAOs.
  • Security First: Built with OpenZeppelin standards and battle-tested patterns to mitigate reentrancy, overflow, and access control risks.
  • Gas Optimization: Expert-level tuning to reduce deployment and transaction costs by up to 40%.
  • Full Lifecycle Support: From initial design and testing to mainnet deployment and upgrade management via transparent proxies.

Deliver a secure, audited MVP in as little as 2-3 weeks, backed by a 99.9% uptime SLA for deployed contracts.

PROVEN FRAMEWORK

Our Methodology for Delivering Secure Cross-Chain Systems

We build token-gated access control that works seamlessly across Ethereum, Solana, and other major L1/L2 networks. Our systematic approach ensures security, interoperability, and a superior user experience from day one.

01

Architecture & Protocol Selection

We design your system's foundational architecture, selecting the optimal protocols (e.g., LayerZero, Wormhole, Axelar) and token standards (ERC-20, SPL, ERC-1155) based on your target ecosystems and security requirements.

Frequently Asked Questions on Cross-Chain Token Gating

Get clear answers on timelines, costs, and technical details for implementing secure, multi-chain token-gated access control.

A standard implementation for a single application with support for 2-3 major chains (e.g., Ethereum, Polygon, Arbitrum) takes 2-4 weeks from kickoff to production. Complex ecosystems with custom NFT logic, multi-wallet support, or 5+ chains typically require 6-8 weeks. Our agile process includes a 1-week discovery & design phase, followed by 2-3 sprints of development and testing.
