Crypto App Development Services

The biggest thing driving the price is whether your app ever holds customers' coins. If it does not, and people keep their own keys, the build is smaller, cheaper and far simpler legally. If it does, you are paying for custody software such as Fireblocks, identity checks on every customer and a security review, all billed monthly rather than once.

Three to six months for the app itself. If you hold coins on customers' behalf, add time for your custody provider's security review before they release live keys, and that queue is theirs, not ours. Apps where users keep their own keys skip it entirely and launch sooner. We start on the test environment in week one.

Yes: one blockchain, one or two coins, send, receive and balances. Every extra chain is its own piece of work rather than a setting, with different fees, address formats and ways transactions fail. The one thing we will not defer is account recovery. Letting someone back in after they lose their phone has to be designed in from the beginning.

We build apps that handle keys, balances and payments that cannot be reversed, where a careless retry sends money twice. That covers connecting an existing wallet through WalletConnect, signing transactions, price feeds and screening an address before you accept funds from it. Names we pass on one to one, away from this page.

Wallet creation and recovery, balances, send and receive, transaction history and a price feed. If you hold customers' coins, add identity checks at sign-up and address screening against sanctions and known thefts, which services like Chainalysis provide. Staking, swaps and card top-ups are what everyone asks for next, and none of them belong in version one.

Because we steer you towards the cheaper, simpler design first, which usually means customers keep their own coins and you never touch them. That also keeps you clear of most of Europe's new crypto licensing regime, MiCA. We never hold keys ourselves and would refuse a build that let us. Afterwards the code, the accounts and the store listings are yours.
