Web3 Development Cost (2026 Guide)

How much does Web3 / dApp development cost?

A single smart contract runs $8,000–$25,000. A full dApp with contracts and a front end is $20,000–$50,000. A DeFi platform or exchange starts around $50,000 and climbs fast. A security audit is a separate $5,000–$30,000. We have shipped exchanges and token systems used by real users, here’s what Web3 actually costs in 2026.

Web3 development cost by scope

What you’re building	Typical scope	DappaSol	US/UK agency
Smart contract	Token, staking, vault	$8k–$25k	$30k–$70k
dApp + contracts	Wallet connect, front end	$9,900–$50k	$80k–$200k
Telegram Mini App	TON payments, viral loops	from $2,500	$30k–$80k
DeFi / exchange	Swaps, liquidity, DEX	$50k–$150k+	$200k–$500k+

Security audits add $5k–$30k. See our Web3 service and Telegram Mini Apps.

What moves the Web3 number

Security & audits

Web3 is adversarial, bugs cost real money. We write audit-ready code with test coverage against standards like those in the Solidity documentation and coordinate reviews with firms such as ConsenSys Diligence; a third-party audit is a separate line item you should budget for.

Chain & standards

EVM, Solana, TON, Cosmos, each has different tooling and effort. Building on TON, for instance, means working against TON’s own documentation rather than EVM tooling. Token standards, bridges and cross-chain add scope.

Front end & UX

Making wallet connect and signing feel normal to non-crypto users is real design work.

Proof: we built for ShapeShift, Komodo and Energy Web.

Web3 from $9,900, built by people who shipped it

Almost no $20–50k studio can claim ShapeShift, Komodo and Energy Web. We can. Fixed price, senior engineers, a demo every Friday, 100% code ownership.
