Wallet development

Crypto wallet development for non-custodial and MPC wallets

We build mobile, web and browser extension wallets across EVM chains, Solana and TON, with key handling designed in writing and reviewed before launch.

What does crypto wallet development cover?

A wallet looks simple on screen, but it is a security product. Crypto wallet development covers key generation and storage, transaction building and signing, chain connections, token and NFT display, a transaction history, notifications and the app itself on iOS, Android, web or as a browser extension.

We begin by asking who your users are, which chains they need and how much key responsibility they should carry. The answers decide the architecture, and we put it in writing before building.

Which wallet model should you choose?

There are three common models, and each trades convenience against control.

  • Non-custodial with a seed phrase: the user holds the keys. It is simple and familiar, but a lost phrase means lost funds.
  • MPC wallets: the key is split into shares held by different parties, so there is no single seed phrase and recovery can be designed around the shares. It adds server components and more design work.
  • Smart contract wallets: account abstraction on EVM chains allows social recovery, spending limits and sponsored fees, with contract risk added.

A custodial wallet, where you hold user keys, is a different business with different regulation, and we will tell you plainly if that is what a design implies.

What features can the wallet include?

Typical building blocks include multi-chain accounts across EVM chains, Solana and TON, token swaps routed through DEX aggregators such as 1inch, Uniswap or Jupiter, and sign-in with a wallet. We can add hardware wallet support for Ledger and Trezor over WebUSB or Bluetooth, biometric unlock, address books, fiat on-ramp links and WalletConnect support.

Chain-specific work is covered on our EVM, Solana and TON pages. If your wallet needs custom contracts, they fall under smart contract development.

A Web3 dApp or wallet MVP, meaning a multi-chain wallet or dApp with token swap and sign-in, typically costs $8,500 to $16,000. Typical delivery is 3 to 4 weeks once the scope is agreed.

That is a typical range, not a quote. More chains, MPC infrastructure, hardware wallet support or custom interfaces move it up. You receive a written quote after a scoping call, and payment follows milestones. See pricing and packages for the full picture.

What are the limits and risks?

A non-custodial wallet cannot recover a lost key unless the design includes a recovery method, and every recovery method adds some risk. Wallet code that handles keys should be reviewed by someone other than its author, and we include a review before launch, which reduces risk without removing it.

We build software and we do not give legal or financial advice. Whether your wallet needs a licence depends on your country and on whether you ever control user funds, and that decision is yours.

How it works

  1. Tell us what you want to build

    A wallet, exchange, contract, bot or payment flow, and the chains involved.

  2. We scope and quote

    You get an architecture outline, a timeline and a written price range.

  3. We build in milestones

    Working builds are shared at each milestone, with a security review before launch.

Questions about crypto software agency in United States

What is the difference between a custodial and a non-custodial wallet?

In a non-custodial wallet the user holds the private keys and the company cannot move their funds. In a custodial wallet the company holds the keys on behalf of users. Custodial services usually face stricter licensing and security duties. We build non-custodial and MPC designs, and we discuss custody questions openly during scoping.

Can the wallet work on several blockchains?

Yes. A multi-chain wallet can support EVM chains such as Ethereum, Arbitrum, Base and BSC, plus Solana and TON. Each chain adds its own signing format, fee model and testing effort, so the number of chains affects both price and timeline.

Do you support Ledger and Trezor?

We can integrate Ledger and Trezor devices over WebUSB or Bluetooth where the platform allows it. Browser and operating system support varies, so we confirm which combinations you need during scoping and test those specific paths. Anything we cannot support on a given platform is listed in the scope before work starts.

Can I get a wallet on both iOS and Android?

Yes. Wallets can ship as native apps, a cross-platform app, a web app or a browser extension. We recommend a platform mix after we learn where your users are. App store review rules apply to wallets, and we cannot promise approval.

Who owns the wallet source code?

You do. The code, the developer accounts and the hosting you pay for are yours. We sign an NDA on request and hand over documentation with the final milestone, including build steps, environment settings and a description of how keys and recovery are handled, so another engineer can maintain it.
