I run a blockchain development agency. I’ve quoted hundreds of projects. And I’m about to do something most agency owners would consider career suicide – I’m going to tell you exactly what things cost.
Not the “it depends” answer. Not the “contact us for a quote” runaround. Real numbers. By project type. From the inside.
Here’s why: you deserve to know what you’re walking into before you sign anything. And if knowing the real numbers scares you away from us, you were probably going to have a bad time anyway.
So let’s get into it.
The short version…
If you don’t want to read 1,400 words, here’s the cheat sheet:
Simple token or basic smart contract: $5K – $30K. MVP or proof of concept: $20K – $50K. Mid-complexity dApp: $60K – $150K. DeFi platform: $47K – $295K depending on type. NFT marketplace: $45K – $300K depending on scope. Blockchain game: $45K – $550K+. Cross-chain bridge: $80K – $400K. DAO with governance: $35K – $200K. Crypto wallet: $60K – $350K+. Enterprise platform: $150K – $500K+.
Those ranges are wide on purpose. Because the real cost depends on what you’re actually building – not what someone slapped on a landing page. Let me break it down.

What drives the price…
Every blockchain project has the same four cost layers. Doesn’t matter if you’re building a wallet or a DeFi protocol – these four things eat your budget:
First – smart contracts. The on-chain logic. This is where most of the security risk lives, so it’s where most of the testing happens. A simple ERC-20 token might take a week. A multi-pool DeFi protocol takes months.
Second – frontend and user experience. The part your users actually touch. This is where most projects blow their budget – because everyone underestimates how much work goes into making Web3 feel like Web2. We wrote a whole piece on blockchain UX design if you want the full picture.
Third – backend, indexing, and infrastructure. Event listeners, transaction processing, database sync, API layers. The invisible plumbing that makes everything work. Most quotes bury this under “backend” without telling you what’s in it.
Fourth – security and audits. Smart contract audits alone run $5K for a basic token to $500K+ for complex DeFi. This is the line item most founders cut first and regret most.
Now let me walk you through what each project type actually costs – and where agencies pad the quotes.
Cost by project type…
I’ve written dedicated breakdowns for each of these. I’ll give you the headlines here and link to the full math.
DeFi platforms
Staking apps start around $47K – $85K. Automated market makers (AMMs) run $93K – $173K. Lending protocols hit $150K – $295K. Yield aggregators land somewhere in the $115K – $215K range.
The biggest cost driver? Audit scope. A lending protocol touching user funds needs $50K – $150K in audits alone. That’s not optional – it’s the cost of not getting hacked.

NFT marketplaces
Art-focused platforms: $60K – $120K. Gaming NFT marketplaces: $90K – $250K. RWA-backed NFT platforms: $120K – $300K+.
The trap here is the “OpenSea clone” pitch. Agencies quote $30K for an “NFT marketplace” that’s really just a frontend skin on top of existing contracts. It looks like OpenSea. It works like a high school science project.

Blockchain games
Hyper-casual GameFi: $45K – $95K. Mid-core with token economy: $110K – $240K. Full GameFi with on-chain assets: $250K – $550K+.
Game dev is the most commonly over-quoted project type in Web3. The “custom game engine” line item is where agencies hide the biggest markup. Unless you’re building the next AAA title, you don’t need one.

Cross-chain bridges
$80K – $400K. I know that’s a big range. It’s because bridges are one of the highest-risk categories in all of crypto. The Bybit hack – $1.5 billion – went through a bridge exploit. Security here isn’t a line item. It’s the whole project.
Expect 30-40% of your total budget to go to audits and security.

DAOs
Simple governance DAO: $35K – $80K. Treasury management DAO: $75K – $140K. Full-stack DAO with sub-DAOs: $130K – $200K+.
The DAO space has a unique pricing problem – governance modules look simple but they’re not. Multi-sig treasury logic, delegation systems, and proposal execution contracts stack up fast.

Crypto wallets
Basic single-chain: $60K – $120K. Multi-chain consumer wallet: $120K – $220K. Full DeFi wallet with swaps and staking: $200K – $350K+.
The “MetaMask clone” quote is the wallet version of the OpenSea clone. If an agency quotes you under $50K for a multi-chain wallet, they’re either cutting security or delivering a reskinned white-label.

Smart contracts (standalone)
Simple token: $5K – $15K. Token with custom logic: $15K – $50K. Complex protocol contracts: $50K – $200K+.
We break down the five cost layers – code, testing, audit, deployment, and integration – in our smart contract development cost guide. The testing-to-code ratio should be at least 2:1. If your quote doesn’t show testing as a separate line item, that’s a red flag.
dApps (general)
$40K – $150K for most use cases. The dApp development cost breakdown covers the full stack – from smart contracts to frontend to infrastructure.
Tokens
Simple ERC-20: $3K – $8K. Token with vesting and governance: $15K – $50K. Full token ecosystem with staking: $40K – $100K+.
Our token development cost guide shows you where agencies pad the quote and when you don’t even need a custom token.
The hidden costs nobody quotes…
Here’s what won’t be on your initial proposal:
Post-launch maintenance runs $3K – $8K/month for monitoring, bug fixes, and infrastructure. Our post-launch cost guide has the full Year 1 breakdown. And if you want the week-by-week playbook, check the post-launch checklist.
Security reviews after major updates. Every significant contract change needs a re-audit. Budget $5K – $15K per review.
Gas optimization. On mainnet, inefficient contracts cost your users real money on every transaction. Good agencies build this into development. Bad agencies charge extra for it later.
Then there’s the in-house vs agency math. A senior Solidity developer costs $180K – $250K base – and the loaded cost is 1.7-1.9x that. Plus you still need frontend, backend, QA, and design. The hiring market is rough right now.
How to not get ripped off…
Three things. That’s all you need.
Get a fixed-price quote. Hourly billing on blockchain projects is how agencies turn a $50K build into a $120K one. Our hourly rates guide explains why – and how to use hourly rates as a benchmark even when you’re paying fixed.
Write a real RFP. Vague requirements get vague quotes. Vague quotes get expensive surprises. Here’s how to write a blockchain RFP that gets you accurate numbers.
Know the red flags. We published a whole guide on how to vet a blockchain agency – including the bait-and-switch, exit fees, and locked code tricks that cost founders $10K – $50K.

If you’ve got a project and you want real numbers – not a landing page range – get in touch. We’ll scope it in a week.
Frequently asked questions…
The 7 most expensive mistakes founders make are documented in detail here: Web3 startup mistakes that cost $50K+.
How much does blockchain development cost in 2026?
Blockchain development costs range from $5K-$30K for a simple token or smart contract, $20K-$50K for an MVP, $60K-$150K for a mid-complexity dApp, up to $200K-$550K+ for complex platforms like DeFi protocols or blockchain games. The four main cost layers are smart contracts, frontend/UX, backend infrastructure, and security audits.
What is the most expensive part of blockchain development?
For most projects, security audits and the frontend/UX layer are the biggest cost drivers. Smart contract audits alone cost $5K for a basic token up to $500K+ for complex DeFi protocols. The frontend is expensive because making Web3 feel intuitive requires significant UX engineering – wallet connections, transaction states, error handling, and gas estimation all need custom work.
How much should I budget for blockchain app maintenance after launch?
Budget $3K-$8K per month for ongoing maintenance, which covers monitoring, bug fixes, infrastructure costs, and minor updates. Every significant smart contract change also requires a security re-audit at $5K-$15K per review. A good rule of thumb is to budget 15-20% of your initial development cost annually for maintenance.
Is it cheaper to hire blockchain developers or use an agency?
For most projects under $200K, an agency is cheaper. A single senior Solidity developer costs $180K-$250K per year in base salary (loaded cost is 1.7-1.9x that), and you still need frontend, backend, QA, and design. An agency gives you the full team for a fixed project price. In-house hiring makes more sense once you have ongoing product development work that justifies 3-4 full-time engineers.
