Taking on new smart contract & DApp projects — room for 2 more this month Taking 2 more projects this month

1,000+ Web3 projects delivered

We build the smart contracts and the Web3 apps that run on them.

We're a team of smart contract and front-end engineers led by Shamrat. We help companies launch tokens, presales, staking platforms and NFT drops on Ethereum, BNB Chain, Polygon and other EVM networks. You bring the idea — we write the code, test it until it holds, and explain every step in plain English so you always know what you're paying for.

Services

Web3 development services — here's what we can build for you

These are the eight things we build most often. Take just the piece you're missing, or hand us the whole launch and we'll carry it from first sketch to live on mainnet.

Smart Contract Development

This is the code that holds your token and your users' money. We plan exactly who is allowed to do what, write it carefully, then try to break it ourselves before anyone's funds are involved.

  • Tokens, NFTs or rules built just for you
  • Built on OpenZeppelin, the industry standard
  • A full test suite you can run yourself

ICO & Presale Platforms

A safe place for people to buy your token before it lists publicly. Prices can rise in stages, the total raise is capped, and buyers get a claim button that actually works on launch day.

  • Buyers can pay in crypto or stablecoins
  • Tokens released gradually, on your schedule
  • A dashboard so you can watch the raise live

Token Launch Engineering

Your token, launched the right way: a small fee on trades if you want one, protection from the bots that snipe new listings, and every wallet allocation split exactly as you planned it.

  • Works on Ethereum and BNB Chain, publicly verified
  • Bot protection for those risky first minutes
  • Liquidity, team and treasury shares set up front

DeFi Protocol Development

Let people lock up your token and earn rewards for it. The tricky part is making sure the reward maths still adds up after thousands of users — so we prove it with tests before launch.

  • Staking pools and liquidity farms
  • Locked vaults with release dates
  • Every reward calculation test-checked

NFT Contracts & Mint DApps

An NFT drop that mints without drama. Early supporters get first access, prices can change by phase, artwork stays hidden until sell-out, and the page holds up when everyone arrives at once.

  • Early-access lists for your community
  • Mint phases with different prices
  • Artwork revealed after the drop

Full-Stack DApp Development

The website your users actually see and click. Quick on a phone, easy to follow, and clear enough that someone's very first crypto purchase doesn't go wrong.

  • Connect a wallet in one tap
  • MetaMask, WalletConnect, Coinbase and Trust
  • Every step explained in normal words

Web3 Tooling & Automation

The behind-the-scenes tools most teams only miss during launch week — sending tokens to thousands of wallets, running jobs in bulk, and bots that handle the repetitive parts.

  • Airdrops to thousands of wallets, cheaply
  • Launch repeat contracts from one place
  • Telegram and Discord bots

Contract Review & Hardening

Already have code, from us or anyone else? We'll go through it the way an attacker would, write up everything we find in language you can act on, and then actually fix it.

  • A written report, sorted by how serious it is
  • Problems fixed, not just pointed at
  • Ready to hand to a formal auditor

Smart contracts by chain

Smart contract development for every major EVM chain

Not sure which chain to pick? Tell us your budget and audience and we'll recommend one. We write the contract once and set it up for whichever network you choose — and adding another chain later is a settings change, not a rebuild.

Ξ

Ethereum

The most trusted network. Best when security matters more to you than transaction fees.

  • Tokens and NFT collections
  • Presales and vesting
  • Code publicly verified
B

BNB Smart Chain

Low fees and a big trading crowd — the most common first choice for a token launch.

  • Tokens with trade fees
  • Protection from bots
  • PancakeSwap liquidity
P

Polygon

Very cheap transactions, which suits NFT mints and paying rewards to lots of people.

  • NFT collections
  • Reward payouts
  • Users can mint fee-free
A

Arbitrum

Much cheaper than Ethereum but still protected by it. The usual home for DeFi.

  • Staking and vaults
  • Moving funds between chains
  • Code publicly verified
◉

Base

The easiest chain for people brand new to crypto — signing up takes seconds.

  • Sign in without a wallet app
  • Mint and social apps
  • Code publicly verified
O

Optimism

Cheap to use and closely tied to Ethereum, with strong support for community voting.

  • DeFi platforms
  • Voting and governance
  • Ready for the Superchain
▲

Avalanche

Transactions settle almost instantly, which helps for trading and payments.

  • Standard contracts
  • Advice on your own subnet
  • Code publicly verified
+

Any EVM network

Fantom, Cronos, Linea, zkSync, Blast, opBNB — even your own chain. If it runs Ethereum-style contracts, we can deploy there.

  • Your network set up for you
  • Always tested on a test network first
  • Deployment scripts included

Frontend & DApps

Web3 DApp frontend development — the website users actually touch

A contract on its own isn't a product yet. We build the screens on top of it, so your users always understand what they're about to approve and what it will cost them.

01

Signing in just works

MetaMask, WalletConnect, Coinbase and Trust all supported. If someone's on the wrong network, the site says so and offers to switch — and it remembers them after a refresh.

02

Buy and mint pages

Current price, how much is left, a countdown, and a history of what each person bought. All read live from the blockchain, so the numbers are never stale.

03

Staking dashboards

Users can see what they've locked, what they've earned so far, and when it unlocks — on one page that loads quickly instead of ticking in slowly.

04

A control panel for your team

Open the sale, change the price, pause trading or withdraw funds with a button — no developer needed, and no typing commands into a black terminal window.

05

Websites people can find

Landing pages, whitepaper sites and documentation, built to load fast and rank on Google — so your project gets discovered, not just funded.

How it works

How we'll work together, step by step

The same four stages whether you need one small contract or a full token launch. You'll always know which stage we're in and what comes next.

  1. 01

    We plan it together

    We talk through what you're building, how the money moves and which chain fits. You get it in writing, with a fixed price and date, before I write any code.

  2. 02

    We build and test it

    We write the code and its tests side by side, put it on a free test network, and show you progress in small updates — no waiting weeks for one big reveal.

  3. 03

    We try to break it

    We attack the code the way a thief would, close anything we find, then trim the transaction fees. Only then does it go live, with the code published for anyone to check.

  4. 04

    You launch, we stay close

    The website goes live, we walk you through your control panel, and we're reachable through launch week in case anything needs a quick hand.

Working together

Three ways to work with us

All three are paid in stages: you see the finished work, approve it, then pay for that stage. Nothing large up front, and no monthly lock-in.

One job

A single piece of work

You know exactly what you need — a token, a staking contract, a mint page, or a check-over of code you already have.

  • Agreed in writing, at a fixed price
  • Tests and deployment scripts included
  • Code published and verified on-chain
  • Usually 3 days to 2 weeks
Get a price

Ongoing help

A few days a month

Time set aside for you each month — for teams who already have something live and keep adding to it.

  • You go first when something breaks
  • New features whenever you need them
  • We keep an eye on costs and uptime
  • Month to month, cancel whenever

About

We build the parts of Web3 that can't afford to break

We're a team of smart contract and front-end engineers, led by Shamrat, and we've spent the last few years doing one thing: writing the code that holds people's money, and building the websites they use to reach it. Both halves come from the same team, which saves you from the usual gap between a contract developer and a web developer who never speak to each other.

We'd rather tell you something is a bad idea than quietly build it. If your timeline is too tight or a feature will put your users at risk, you'll hear that early — while it's still cheap to change.

  • You talk to the engineers. No account manager in the middle, no relay.
  • Everything is yours. The code, the contracts and the keys, from day one.
  • No jargon. We explain what we built and why, in words you can repeat to your team.

FAQ

Questions people ask us first

If yours isn't here, just email us — we answer these all day and we don't mind at all.

I'm not technical. Can you still help me?

Yes, and a good share of our clients are in exactly that position. You don't need to know what a smart contract is — you just need to know what you want your project to do. We'll explain the options in plain language, recommend the sensible one, and handle everything technical from there.

Can you build both the contracts and the website?

Yes, and it's what most people ask for. You get the contracts and the website that connects to them — wallet sign-in, buy and claim buttons, and a control panel for your team. Because one team builds both halves, there's no gap where two agencies blame each other.

How long will my project take?

A straightforward token, tested and live, is usually 3 to 5 days. A complete presale platform with a dashboard, lock-up schedules and claims runs 2 to 4 weeks depending on how much it needs to do. We'll give you a firm date before we start, not a vague range.

What does it cost?

It depends on what you're building, so we quote per project rather than posting a price list that would mislead you. Send us a short description and you'll get a real number, not a "contact us for pricing" runaround. Payment is split into stages, so you're never far out of pocket.

How do I know the code is safe?

Every contract comes with a full set of automated tests, and we spend time deliberately attacking our own code — trying to drain it, break its limits or get around its permissions. The finished code is published on the blockchain explorer so anyone can read it, and we can work alongside an outside auditor if your launch needs that.

Do I own the code?

All of it. The code, the contracts and the keys are yours, delivered into your own repository with written notes. Nothing is locked to us, and any developer can pick it up after we're done.

Can you rescue a project someone else started?

Often, yes — it's a regular request. We'll read through what exists, tell you honestly what's usable and what isn't, then fix, finish or rebuild the parts that need it. You'll get that assessment before you commit to the work.

Which blockchain should I choose?

Tell us who your users are and what your budget is, and we'll recommend one. As a rough guide: BNB Chain for a cheap, fast token launch, Ethereum when trust matters most, Polygon or Base when you want low fees for lots of everyday users. Adding a second chain later is straightforward.

Contact

Tell us what you're building

You don't need a finished plan or the right vocabulary — a few sentences is plenty. Tell us what you have in mind and when you need it, and we'll reply with an honest answer on whether we can help, how long it would take and what it would cost. Usually within one working day.
