What we build
Wallet types and platforms we build
Desktop wallets
Desktop wallets for teams and power users who want keys on their own machine: encrypted local storage, hardware wallet pairing, and full transaction history without a browser in the loop.
Web wallet development
Browser-based wallets with no install step: MPC or encrypted key vaults on the backend, WalletConnect support, and session security designed around the web threat model.
Multi-currency wallets
One wallet for many assets. We implement HD key derivation (BIP32/39/44) so a single seed manages coins and tokens across chains, with unified balances and history.
DeFi wallets
Wallets that talk to DeFi protocols directly: token approvals, staking, lending, and swap routing built in, with transaction simulation so users see the outcome before they sign.
NFT wallets
Wallets for creators and collectors: ERC-721 and ERC-1155 support, media rendering, collection views, and transfer flows that guard against wrong-address mistakes.
Bitcoin wallets
Bitcoin-specific wallets with SegWit and Taproot address support, UTXO management, fee estimation, and optional multisig for treasury-grade custody.
Ethereum wallets
Ethereum wallets covering ETH, ERC-20 tokens, and smart contract interaction, including EIP-1559 fee handling and account abstraction (ERC-4337) where it fits the product.
Multichain wallet development
One interface across Ethereum, Solana, BSC, Polygon, and other networks. Per-chain signing logic sits behind a common account model, so users switch chains without switching apps.
Features
Wallet features that matter in production
Two-factor authentication and step-up security
2FA, biometric login, and device binding on every sensitive action. Withdrawals and key exports can require step-up verification, so a stolen password alone gets an attacker nothing.
Multi-device access
The same wallet on phone, laptop, and tablet with encrypted state sync. Sessions are scoped per device and can be revoked individually when hardware is lost or replaced.
Multi-currency management
Hold and move many assets from one interface: unified balances, per-asset transaction history, and consistent fee handling whether the user sends BTC, ETH, or an ERC-20 token.
QR code transactions
Scanning a QR code fills the address and amount automatically. That removes copy-paste errors, the most common way funds end up at the wrong address, and speeds up in-person payments.
Chrome extension support
A browser extension build lets your wallet inject a provider into web pages, so users sign dApp transactions straight from the toolbar, the interaction pattern the market already knows.
In-chat crypto transfers
Send and receive crypto inside a chat flow: payment requests resolve to addresses behind the scenes and both sides get confirmation in the thread. A strong fit for social and P2P products.
Why Webisoft
Why choose Webisoft for blockchain wallet development?
Blockchain engineers, not generalists
1Webisoft is a Montreal software studio that ships blockchain products end to end: wallets, smart contracts, and the infrastructure behind them. You work with engineers who understand key management, not a brochure team.
Built to your custody model
2Custodial, non-custodial, MPC, or multisig: we design the wallet around your regulatory position and user base, not around a template. Every feature is scoped to your product goals.
Security as an engineering discipline
3Threat modeling before code, encrypted key storage, reviewed and signed releases, and preparation for third-party audits. Wallet security is designed in from the start, not patched on later.
Support through launch and after
4We stay through integration, audit, launch, and maintenance. When a chain upgrade or dependency change lands, the team that built your wallet is on hand to respond.
Integration with your existing stack
5We wire the wallet into the systems you already run: exchange backends, KYC providers, accounting, and analytics. Clean APIs and webhooks so your operations team sees every transaction.
Full-cycle delivery, one team
6Webisoft runs full-cycle delivery: strategy, architecture, build, audit support, and production operations. One accountable team from the first workshop to mainnet, so nothing is lost in a handoff.
Guide
How we build a blockchain wallet, step by step
- 1
Ground the design in chain mechanics
Every wallet decision follows from how accounts, transactions, and signatures actually work on your target networks. We settle the custody model and key architecture first, because everything else depends on them.
- 2
Define project requirements
We scope the product with you: target users, supported chains and assets, custody model, compliance constraints, and the features version one actually needs. A precise spec here prevents expensive rework later.
- 3
Choose the right tools and frameworks
We pick the stack per chain and platform: wallet SDKs, node providers, signing libraries, and key management (HSM, MPC, or secure enclave). Proven, boring choices where security is on the line.
- 4
Develop and integrate core features
Key generation and recovery, transaction building and signing, balances and history, and integrations with your backend. Built in short iterations you can review, with signing logic isolated and testable.
- 5
Test, audit, and harden
Unit and integration tests on signing paths, testnet dry runs, fuzzing on transaction parsing, and preparation for external security audit. A wallet ships when the attack surface is understood, not when the UI looks done.
- 6
Deploy and maintain the wallet
We release through app stores and the web, monitor in production, and keep pace with chain upgrades, dependency patches, and new asset support. A wallet is a living system, and we maintain it like one.
Engagement
Our engagement models
(3)A dedicated wallet team
A stable Webisoft squad that works only on your wallet: engineers, a technical lead, and a product contact. The right model when the wallet is core to your business and the roadmap runs past one release.
On-demand specialists for your team
Add wallet, smart contract, or security engineers to your existing team for a defined stretch. You keep architectural control; we fill the specific skill gaps that are slowing delivery down.
Fixed-scope custom builds
A defined wallet product, specced and quoted up front, delivered end to end. The right fit when requirements are clear and you want a predictable budget and timeline.

FAQ
Frequently asked questions
(6)- Blockchain wallet development is the design and build of software that stores keys and signs transactions: custodial or non-custodial, on mobile, desktop, web, or as a browser extension. The work covers key management, chain integrations, security hardening, and ongoing maintenance after launch.
- Mobile, desktop, web, and browser-extension wallets, plus hardware wallet integrations. Within those form factors, common builds include multi-currency, multichain, DeFi, and NFT-focused wallets, with custodial or non-custodial key models chosen based on the product's requirements and regulatory position.
- Core protections include encrypted key storage backed by a secure enclave or HSM, 2FA and biometric login, explicit transaction confirmation before signing, withdrawal allowlists, and optional multisig or MPC so no single key can move funds alone. For anything holding real value, an independent security audit before launch is standard practice.
- Wallets are security-critical, so the team should treat the build as a full-cycle engineering project: custody architecture, secure key management, audit preparation, and post-launch maintenance rather than a template adaptation. Prior production wallet experience, familiarity with the target chains, and a documented security process matter more than headline feature lists. Continuity also counts, since the wallet will need maintenance as chains and standards evolve.
- Beyond standard send-and-receive, current builds include MPC and multisig custody, account abstraction features such as gasless transactions and social recovery, in-chat transfers, DeFi integrations, and multichain account models that keep several networks behind one interface. Which features make sense depends on the audience: consumer wallets prioritize recovery and simplicity, while institutional wallets prioritize policy controls and custody guarantees.
- UX should be treated as a security feature. Clear transaction previews before signing prevent costly mistakes, QR-based sends remove copy-paste errors, browser extension and multi-device sync keep access consistent, and recovery flows should be tested with real users rather than only engineers. Most losses in crypto trace back to confusing interfaces as much as to technical flaws, so clarity in the signing flow is worth real design investment.
