TRANSPARENT & AUDITABLE
Our Development Process: From Specification to Mainnet
A rigorous, security-first methodology for delivering production-ready smart contract license verification systems. We de-risk your launch with clear milestones and expert oversight at every stage.
01
1. Discovery & Specification
We conduct a technical deep-dive to define your exact licensing logic, token standards (ERC-20, 721, 1155), and integration requirements. This phase establishes a clear, immutable scope of work.

Frequently Asked Questions on EVM License Verification Development
Get clear answers on timelines, costs, security, and process for implementing robust on-chain license verification for your protocol.
Standard deployments for a single-chain verification contract with core features (minting, validation, admin) take 2-3 weeks from kickoff to mainnet. Complex multi-chain systems with custom revenue splits, upgradeable modules, and integration into an existing dApp frontend typically require 4-6 weeks. We provide a detailed project plan with milestones in the first week.
