Smart contracts written for the problem you actually have
Contract logic should match your business conditions precisely. Generic templates carry assumptions that break under edge cases.
Numbers that describe the work, not the pitch
Across Ethereum, BNB Chain, and Polygon, the contracts we write go through the same audit process regardless of project size. Consistency comes from process, not luck.
Each contract starts with your edge cases, not a baseline template
Off-the-shelf contract code handles the scenario it was written for. When your business has non-standard fee structures, multi-party settlement logic, or time-locked distributions tied to external conditions, templates require workarounds that introduce risk.
Spec-driven scoping
Every project starts with a written functional spec reviewed by both parties before a single line is coded.
Live iteration with the client
Logic changes during development are discussed in real time — no change-request bureaucracy that slows delivery.
Testnet before mainnet, always
No contract reaches mainnet without a documented testnet run covering at least the failure paths, not just the happy path.
Two types of projects come here most often
Not every client arrives in the same condition. Some have tried other routes. Some are starting from a clear spec.
The team with existing architecture
A protocol is already live. A new module — vesting, governance, or a token bridge — needs to integrate without touching the core contracts. The risk is interface mismatch and re-entrancy from the integration point.
The work here involves reading the existing code as carefully as writing the new piece, mapping all interaction surfaces before writing a function.
The founder before the first deployment
There is a business model, a target network, and a deadline. No existing codebase. The challenge is translating non-technical logic — royalty splits, unlock schedules, approval tiers — into deterministic contract behavior.
Writing the spec together is often where the most important decisions get made, before any code is committed.
The mechanics behind a contract that holds up
Security in smart contracts is not a feature added at the end. It is a consequence of how the work is structured from the first conversation.
Functional specification review
The client describes the desired behavior in plain language. We translate that into a Solidity-level spec — data structures, state transitions, access control model — and share it back for sign-off before coding begins.
Modular development with inline natspec
Functions are built in isolation and documented using natspec so external auditors can review without needing a walkthrough call. This reduces audit time and cost.
Hardhat test suite covering revert paths
Unit tests run against Hardhat with explicit coverage targets for every require and revert condition. Tests for the unhappy path are required, not optional.
Testnet staging and client verification
The contract is deployed to the target testnet. The client interacts with it directly, verifying that the behavior matches their expectations under real wallet conditions.
Mainnet deployment with verification
Source code is verified on the block explorer at deployment. The client receives full ownership of contract keys and deployment artifacts — nothing is held back.
The question worth asking any development team: who holds the deployment keys at the end of the engagement. At QurDlanok, full ownership transfers to the client on delivery — admin keys, deployer wallet, contract source, and test suite.
