Web3 Development Cost (2026 Guide)
How much does Web3 / dApp development cost?
A single smart contract runs $8,000 to $25,000. A full dApp with contracts and a front end is $20,000 to $50,000. A DeFi platform or exchange starts around $50,000 and climbs fast. A security audit is a separate $5,000 to $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 to $25k | $30k to $70k |
| dApp + contracts | Wallet connect, front end | $9,900 to $50k | $80k to $200k |
| Telegram Mini App | TON payments, viral loops | from $2,500 | $30k to $80k |
| DeFi / exchange | Swaps, liquidity, DEX | $50k to $150k+ | $200k to $500k+ |
Security audits add $5k to $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: senior engineers whose work has shipped inside ShapeShift, CoinDesk and Komodo.
Web3 from $9,900, built by people who shipped it
Almost no $20 to 50k studio can put senior engineers on it whose work has shipped inside ShapeShift, CoinDesk and Komodo. We can. Fixed price, senior engineers, a demo every Friday, 100% code ownership.
