In Web3, a single smart contract vulnerability can drain all user funds. Any contract managing user assets requires a professional audit before mainnet deployment. Budget $5,000–$30,000 for audit depending on complexity.
Gas fees, wallet setup, and transaction confirmations are massive friction points. Use abstraction layers (account abstraction, sponsored transactions) to make your dApp feel like a normal web app.
Ethereum has the most liquidity but high gas fees. Polygon, Base, and Solana offer lower costs for consumer apps. Pick the chain your target users are already on — don't build and then hope they migrate.
Rough estimates per feature. Our fixed-price MVP bundles all of these — see the full Crypto / Web3 App cost guide.
| Feature | Typical range |
|---|---|
| Wallet connect + auth | $800 – $4,000 |
| Smart contract development | $2,000 – $15,000 |
| Smart contract audit | $5,000 – $30,000 |
| Frontend dApp | $2,000 – $10,000 |
| NFT minting interface | $1,000 – $5,000 |
| Fiat on-ramp | $500 – $2,000 |
| Multi-chain support | $1,000 – $5,000 |
| Total estimate | $12,300 – $71,000 |
We ship production-ready crypto / web3 app MVPs in 3–8 weeks at a fixed price. No hourly billing, no scope creep surprises.
A Web3 app without custom smart contracts (wallet connect, token display, existing protocol integration) costs $10,000–$25,000. Apps with custom smart contracts requiring audits cost $30,000–$100,000+.
Yes, if your contract holds user funds or has any financial logic. Skip it only if you're on testnet or building a display-only interface with no user funds at risk.
