Service area 02 — Smart contracts and audits

A contract you can launch
with real money
without the risk of mainnet losses

We work on projects where the cost of a mistake starts at $100k+. We write smart contracts for specific business logic and run a security review before mainnet. Not GitHub templates — code that reflects your model and is verified before real funds ever touch it.

A typical situation

What people come to us with

🔧

Non-standard logic is neededA template ERC-20 doesn't cover the scenario. You need custom roles, distribution mechanics, compliance restrictions, or multi-level contract interaction logic.

😰

Fear of mainnetThe contract is written, but it's unclear how safe it is. Launching with real money is scary — what if there's a vulnerability that isn't immediately visible?

🏚️

A contract from another contractorThe code exists, but the team is gone or there's no trust in the architecture. An honest review is needed — what's inside, and can it go to audit.

🎯

An audit or listing is comingThe project is heading toward a public launch. An external audit is required — and it matters to enter it with prepared code, not to walk away with a list of 20 Criticals.

These tasks almost always involve $10k+ at risk
What we do

Not "write a contract" — make it production-ready

Security is part of development, not a separate stage afterwards

Most smart contract vulnerabilities don't appear because the developer is bad. They appear because the architecture wasn't designed with real attack vectors in mind — and that surfaces at the audit, or worse, on mainnet.

We start with the business logic: which roles are needed, which scenarios are critical, where role-overlap risks lie, and how the contract should behave in edge states. Then the architecture goes into code — not the other way around.

We're CertiK partners, so the contract is designed to institutional audit requirements from day one. That sharply reduces the number of findings and the time to launch.

What the client gets

A smart contract built for your specific business logic
An architecture accounting for roles, upgrades, and update scenarios
Unit tests for critical scenarios and edge cases
An internal pre-audit: Critical / Major / Medium findings
Technical documentation of the contract and its logic
Repository preparation for the external audit
Support through the CertiK partner channel
The cost of a mistake

One contract mistake can cost anywhere from $50k to $5M

Smart contracts have no "roll back and fix". After deployment, the logic is fixed. If the architecture contains a vulnerability, it will be exploited. The cost of a mistake here isn't technical debt — it's direct financial and reputational loss.

A role-logic mistake — unauthorized withdrawal of funds
Reentrancy or an incorrect calculation — a mainnet exploit
An architecture flaw found at audit — rewriting half the system
Weak security — rejection by investors and listing platforms
Why dimtiks

Why we're a safer choice than a regular dev team

01

We start with architecture, not code

Before writing a line of Solidity, we break down the business logic: roles, scenarios, edge states, risk zones. That prevents vulnerabilities at the design level.

02

CertiK partnership

We work with CertiK as authorized partners. The contract is designed to institutional audit requirements — not rebuilt from scratch right before one.

03

Pre-audit before the external review

We run an internal audit with a real hunt for vulnerabilities — Critical / Major / Medium. The client enters the external audit with prepared code and a minimal list of issues.

04

Real projects with $50k – $2M budgets

12-contract DeFi protocols with Chainlink, security tokens with compliance architecture, bytecode optimization for CertiK. Not practice tasks — production code.

05

Clear documentation

Every contract ships with documentation covering functions, logic, and critical branches. Auditors need it, and so does the dev team that will work with the code next.

06

We don't disappear after deploy

We walk the project through the audit, help close findings, and stay in contact with the external auditors' team. The work doesn't end at the merge into main.

Our work

Completed projects

Case 01

DeFi Lending Protocol — 12 contracts, Chainlink, an audit with zero critical vulnerabilities

The task

The client came not for a single contract but for a full on-chain system: lending / treasury / protocol logic governance / oracle integration. In projects like this, risk emerges at the seams between modules — each part looks fine on its own, but the combination opens vulnerabilities. Launching without serious preparation meant a heavy list of findings at the audit and lost development momentum.

What we did

We started with architecture: broke the business logic into modules, mapped risk zones, roles, upgrade scenarios, and contract dependencies. We designed a system of 12 interconnected contracts with full Chainlink integration. We covered the key scenarios with unit tests and documented the critical logic branches. We ran an internal pre-audit focused on role overlap, incorrect call sequencing, external data dependencies, and abuse points. We fixed the issues before submitting for the external review.

• 12 interconnected contracts

• 0 Criticals in the external review

• System prepared for $500k+ TVL

Stack

Solidity · Hardhat · Chainlink Oracle · UUPS Proxy · AccessControl · Lending Logic · Treasury Module · Unit Tests · Pre-Audit · CertiK Review

The external review came back with zero Criticals. The client got a coherent protocol system with clear architecture and documentation — and avoided the scenario where an audit exposes architectural flaws too late.

Case 02

Security Token ERC-1400 — whitelist, compliance restrictions, and correct ownership logic

The task

The client needed not just a token but a security token contract model with correct ownership logic. Mistakes here are dangerous not only from a hacking standpoint — they're dangerous for the rights model itself: the token can start moving by rules other than the ones the business, the platform, or the legal structure requires. Standard open-source templates don't fit here.

What we did

We started by analyzing ownership scenarios: who can buy the token, who can transfer it, and which checks are mandatory before a transaction. We designed an ERC-1400-based architecture with transfer restrictions and a whitelist built into the system itself. We implemented participant verification, circulation limits, and the link to the KYC/compliance logic. We ran an internal audit focused on the correctness of the business rules inside the contract — not just code security.

• A model for 50–150 participants

• Architecture for a $500k+ tokenized raise

• Compliance-ready logic for listing and audit

Stack

Solidity · ERC-1400 · ERC-3643 · Transfer Restrictions · Whitelist Mechanics · KYC Integration · Compliance Architecture · Role Management · Pre-Audit

The client got a working instrument with correct access logic and transfer restrictions — not a technical token with formal limitations. Security went hand in hand with compliance logic, and participants' rights were implemented exactly as the project's model required.

Who it's for

Who comes to us with this

🚀

Founders before launch

The product is ready and the contract is written — but hitting deploy to mainnet without an honest security and logic review is scary.

🏦

DeFi teams

They need a complex on-chain system: lending, staking, treasury, governance — with the right module interaction architecture.

🔐

Projects heading into an audit

An external audit or listing is ahead. It matters to enter it with prepared code — not to collect 30 findings and go off to rewrite.

🔄

With a contract from another team

The code exists, but there's no trust in the architecture. An honest review is needed — what's inside, and whether it can be launched.

📜

Security token projects

They need compliance logic, transfer restrictions, and whitelist mechanics — where a template token doesn't cover the real scenario.

🌐

Web3 projects with non-standard logic

The task doesn't fit ready-made templates. A custom architecture is needed for a specific business scenario with real money inside.
