About
What Is a Crypto Wallet App?
Step-by-Step
How a Crypto Wallet App Works
A wallet app generates or provisions keys, manages addresses, signs transactions, and broadcasts them to the blockchain through node connectivity. It also tracks confirmations, displays balances, and provides security and recovery workflows to keep users protected.
Wallet Creation & Key Setup
Users create a wallet or import an existing one using a secure key setup flow. We implement UX that reduces mistakes and supports safe onboarding from day one.
Confirmation Tracking & Notifications
The wallet tracks confirmations and updates balances and history in near real time. Notifications keep users informed about received funds, completed transfers, and security events.
Transaction Signing & Broadcasting
Transactions are signed locally (non-custodial) or via custody infrastructure (custodial/MPC) depending on your model. Sign transactions for swapping assets directly on a decentralized exchange (DEX).
Send/Receive & Fee Estimation
Users can send and receive assets with clear fee estimation and network selection. Fee handling supports predictable confirmations and reduces failed transactions.
Address Management & Asset Discovery
The wallet manages addresses and discovers assets across supported networks and tokens. We implement reliable balance indexing and token detection for accurate portfolio views.
Recovery, Support & Security Events
Recovery flows depend on custody model and can include seed phrases, recovery kits, or controlled procedures. Security events and support workflows are designed to reduce loss and speed up resolution.
A crypto wallet app functions through the secure generation and storage of private keys, which are used to generate a digital signature for every transaction. When a user initiates a transfer, the app constructs a transaction object, signs it with the private key within a Secure Enclave or via MPC (Multi-Party Computation), and then broadcasts it to the blockchain network via a node provider (like Infura or Alchemy). To ensure the highest level of security and performance during this cycle, we follow a rigorous technical roadmap, which we have detailed in our comprehensive guide on how to create a crypto wallet app. The app constantly monitors the blockchain's state using WebSockets or polling to reflect confirmed transactions and updated balances in the user interface.

03
Blockchain Connectivity (Nodes/RPC, Indexers)
We connect to node providers and indexing services for balances, history, and real-time updates. Connectivity includes caching and fallback strategies to reduce downtime.
04
Backend Services (If Custodial/Hybrid)
Backend services manage accounts, policies, notifications, and operational workflows when needed. This layer supports admin actions, risk controls, and compliance processes.
Security Layer (Auth, Encryption, Rate Limits). We implement authentication, encryption, and rate limiting where applicable to reduce abuse. Security controls include device checks and suspicious activity detection patterns.
Cost
Cost of Crypto Wallet App Development
The development cost for a custom crypto wallet typically ranges from $45,000 for a white-label or MVP solution to $150,000+ for a feature-rich enterprise platform. In the US market, price volatility is driven by the choice of custody model, the number of integrated blockchains, and the complexity of the security infrastructure. For a deeper financial analysis, we recommend reviewing our latest breakdown of how much it costs to develop a crypto wallet app, which accounts for current labor rates and evolving security standards.
Cost Estimates
Basic (MVP): $25,000 - $45,000
Standard (Pro): $50,000 - $85,000
Enterprise (Custom): $90,000 - $150,000
Developing a secure backend and a cross-platform mobile app (Flutter/React Native) for a basic wallet takes approximately 3 to 5 months. However, adding advanced features such as in-app swaps via DEX aggregators, fiat-to-crypto on-ramps, and multi-signature support for corporate accounts can increase both the timeline and the budget.
At Merehead, we emphasize a cost-efficiency strategy by utilizing pre-tested security modules and proprietary middleware. This approach allows us to reduce development hours by up to 30%, focusing your budget on high-impact areas like smart contract audits and penetration testing, ensuring a robust launch within a predictable financial framework.

Experience
Custody Models We Implement
Choosing the right custody model is vital for your business strategy and user trust. We implement Non-Custodial (Self-Custody) models for users who want full control over their funds, utilizing mnemonic phrases or iCloud/Google Drive encrypted backups.
For institutional clients, we offer Custodial solutions with multi-signature (Multi-Sig) logic and MPC (Multi-Party Computation), which eliminates a single point of failure by splitting the private key into several 'shards' distributed across secure servers. MPC-based custody models often used in institutional-grade exchanges provide the perfect balance between high-speed transaction signing and top-tier asset protection.

MPC-based custody models often used in institutional-grade exchanges provide the perfect balance between high-speed transaction signing and top-tier asset protection.
Non-Custodial (User-Owned Keys)
Users fully control keys and sign transactions on-device. This model maximizes self-custody but requires strong recovery UX and user education.
Custodial (Platform-Managed Keys)
The platform manages keys and executes transactions under policy controls. This model supports recovery and centralized operations but requires stronger security and compliance posture.
Hybrid Custody (Flexible Control)
Hybrid custody combines self-custody UX with platform controls for selected operations. This model works well when you want flexibility across user segments and risk levels.
