PROVEN FRAMEWORK
Our Delivery Methodology
A structured, transparent process designed to deliver secure, scalable token-gated systems on time and within budget. We focus on rapid iteration and clear communication to align technical execution with your business goals.
01
Architecture & Strategy Workshop
We conduct a deep-dive session to define your access control logic, token standards (ERC-20, ERC-721, ERC-1155), and integration points. This ensures the system architecture is scalable and aligned with your product roadmap from day one.

CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production by Web3-native engineers.
We architect and deploy custom smart contracts that form the backbone of your protocol. Our team specializes in Solidity 0.8+ and Rust for Solana, implementing battle-tested patterns from OpenZeppelin and Anchor. Every contract undergoes a multi-stage security review before deployment.
From tokenomics to governance, we translate your business logic into immutable, gas-efficient code.
- Token Standards:
ERC-20,ERC-721,ERC-1155,SPLwith custom minting, vesting, and staking logic. - DeFi Primitives: Automated market makers (AMMs), lending pools, yield aggregators, and derivative contracts.
- Security First: Formal verification, unit/integration testing, and pre-audit by our internal review board.
- Full Lifecycle: Development, deployment to
Mainnet/Testnet, and post-launch monitoring and upgrades via proxy patterns.
EVM Token-Gated Access
Frequently Asked Questions
Common questions about our design and development process for secure, scalable token-gated systems.
A complete, production-ready EVM token-gated access system typically takes 3 to 6 weeks from kickoff to mainnet deployment. This includes 1 week for requirements and architecture, 2-3 weeks for smart contract development and internal testing, and 1-2 weeks for security audits and final integration. Complex multi-chain deployments or custom NFT mechanics may extend the timeline, which we define upfront in the project scope.
