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.
| 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.
Web3 is adversarial — bugs cost real money. We write audit-ready code with test coverage; a third-party audit is a separate line item you should budget for.
EVM, Solana, TON, Cosmos — each has different tooling and effort. Token standards, bridges and cross-chain add scope.
Making wallet connect and signing feel normal to non-crypto users is real design work.
Proof: we built for ShapeShift, Komodo and Energy Web.
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.
