Build a Crypto App in 21 Days
Wallet integration, token dashboards, DeFi interfaces, and on-ramp — without the 6-month Web3 agency quote.
Why Crypto & Web3 App development is hard to get right
Web3 agencies quote $50K–$200K for basic wallet-connected apps — most founders need a focused MVP, not a protocol
Wallet integration (MetaMask, WalletConnect, Coinbase Wallet) has edge cases that break UX for non-crypto-native users
On-ramp (fiat → crypto) requires licensed partners — MoonPay, Transak, or Stripe Crypto handle compliance
Smart contract audits cost $15K–$50K — for MVPs, use audited primitives (OpenZeppelin) not custom contracts

Frequently asked questions
Do you write custom smart contracts?
For MVPs, we integrate with audited existing protocols. Custom contracts require separate audit budget ($15K+). We scope this explicitly before starting.
Which chains do you support?
Ethereum, Base, Polygon, and Solana for most MVPs. We pick based on your user's chain preference and gas cost tolerance.
