Why wallets are a security product first
A wallet is a key-management product with an interface attached, and key management is where projects die: keys lost, keys stolen, recovery flows that help attackers more than users. We design custody models deliberately, custodial with proper controls, non-custodial with real self-sovereignty, or MPC split where the trade-off suits, and document the threat model before building the UI.
On top of that foundation sits the product: multi-chain support, transaction clarity, and onboarding that mainstream users survive. Custody and contract work inherits the standards of our blockchain development practice.
What our crypto wallet development services cover
The full wallet stack, from key ceremonies to polished apps.
Non-custodial wallets
Self-custody wallets where users hold keys, with recovery UX that protects users without weakening security.
- ✓Seed phrase and passkey flows
- ✓Social recovery options
- ✓Encrypted backups
- ✓Clear security education
Custodial wallet infrastructure
Institutional custody with HSM or MPC key storage, policies, and audit trails regulators can inspect.
- ✓MPC/HSM key storage
- ✓Withdrawal policies
- ✓Address allowlisting
- ✓Full audit logging
Multi-chain support
Wallets operating across Ethereum, EVM chains, Solana, and Bitcoin with unified balances and activity.
- ✓Multi-chain architecture
- ✓Unified balance views
- ✓Chain-specific signing
- ✓Token standard coverage
In-app wallet sDKs
Embedded wallets inside your product, so users transact without managing a separate app or seed phrase.
- ✓Embedded wallet SDK
- ✓Session-based signing
- ✓Fiat on-ramps
- ✓Progressive security tiers
Transaction intelligence
Clear transaction previews, risk warnings, and simulation so users know what they are signing before they sign it.
- ✓Human-readable previews
- ✓Simulation before signing
- ✓Contract risk flags
- ✓Fee display done honestly
Security review and penetration focus
Review of key flows, signing paths, and recovery procedures, with remediation verified before launch.
- ✓Threat model documentation
- ✓Key flow review
- ✓Recovery path testing
- ✓Remediation verification
What every engagement includes
Every crypto wallet project ships with the following, agreed in writing before the first sprint begins.
Discovery workshop
A structured workshop maps your goals, users, and constraints into a scoped crypto wallet roadmap with a fixed written quote before any sprint starts.
Named senior team
You get named, senior engineers with CVs you can review, not a rotating bench. The people in the kickoff are the people who ship.
Sprint demos every two weeks
Working builds are demoed live each cycle with CI running on every merge, so progress is visible in software, not slideware.
100% source-code ownership
All crypto wallet source, configurations, designs, and documentation transfer to you on delivery with no licensing strings or vendor lock-in.
60 days of post-launch support
Engineering time is on standby for two months after go-live to triage defects, tune performance, and stabilise the release at no extra cost.
12 months of free updates
Compatibility updates, security patches, and platform upgrades ship free for a full year after handover.
What you can build with wallet development
Wallet products our team delivers, key management treated as the core.
Consumer Multi-chain wallet
A mobile-first self-custody wallet with clear transaction previews and recovery that ordinary users complete.
Institutional custody platform
Custody with MPC key storage, withdrawal policies, and audit trails built for compliance review.
Embedded In-app wallet
A wallet SDK inside your product so users transact without leaving, with security tiers that grow with balances.
Exchange wallet infrastructure
Deposit, withdrawal, and sweep infrastructure for exchanges, with reconciliation and anomaly detection.
White-label wallet product
A branded wallet product on proven custody architecture, customised to your market and chain targets.
How a crypto wallet Project Runs
Six stages, each with a sign-off gate before the next begins.
- 01
Discovery
We map your wallet goals, users, and constraints in a structured workshop, ending in a fixed written quote and an architecture risk list.
✓ step 01 complete - 02
Solution design
The crypto wallet architecture, integrations, and delivery plan are designed and reviewed before build work starts, so scaling later is not a rewrite.
✓ step 02 complete - 03
Foundation sprint
Repositories, CI, environments, and a walking skeleton are set up first. Something real runs on a staging URL before feature sprints begin.
✓ step 03 complete - 04
Sprint delivery
Two-week sprints with live demos every cycle. crypto wallet work is reviewed, tested, and merged continuously, so scope surprises surface early.
✓ step 04 complete - 05
Hardening and launch
Performance, security, and accessibility checks run against agreed budgets, followed by a staged wallet launch with monitoring from hour one.
✓ step 05 complete - 06
Support and handover
60 days of included support, 12 months of free updates, and documentation that lets your internal team own the system with confidence.
✓ step 06 complete
The stack behind our wallet builds
Default choices, stated with reasons.
Key management
MPC and HSM architectures for custody, hardened seed and passkey flows for self-custody, with threat models documented before code.
Chains
Ethereum, EVM L2s, Solana, and Bitcoin support through maintained chain clients, with signing isolated per chain.
Apps and sDKs
Native mobile and web front ends plus SDK packages, with biometric-backed local storage and secure enclaves used properly.
Monitoring
Transaction monitoring, anomaly detection, and alerting on withdrawal patterns, tuned to catch compromise attempts early.
How intelligence flows through the wallet
What each layer reads, and what it changes.
Transaction risk engine
Scores transactions and contracts before signing.
Reads
Transaction payloads, contract metadata
Changes
Warning states and approval prompts
Anomaly detection
Watches account activity for compromise patterns.
Reads
Transaction history, device signals
Changes
Alerts and step-up authentication
Assistant
Explains transactions and answers wallet questions plainly.
Reads
Transaction data, help content
Changes
In-app guidance and support replies
What's included, standard
The baseline on every crypto wallet engagement. Not an upsell tier, just the floor.
Fixed written quote
The price agreed at discovery is the price you pay, with change handled through explicit scope changes rather than silent drift.
Solution architecture document
System design, data flows, and technology decisions written down so your team can audit and own the result.
Dedicated project manager
One accountable point of contact with real authority over the delivery, not a message relay between time zones.
QA on every build
Automated and manual testing on each crypto wallet release candidate, with defects triaged before anything reaches production.
Security review
A checklist-based security pass covering authentication, data handling, and dependency vulnerabilities before launch.
CI/CD and environments
Pipelines, staging, and preview environments configured from week one, so releases are routine rather than dramatic.
Analytics and monitoring
Instrumentation wired before launch so you can see real user behaviour and system health from day one.
Documentation and handover
Code comments, runbooks, and architecture notes written for your next developer rather than for our convenience.
Threat model documentation
A documented threat model covering key flows, recovery, and attack surfaces, reviewed with your team.

Why teams pick us for wallet work
The differences live in engineering habits, not pitch decks.
Threat models before uIs
We document the attack surface and custody trade-offs first, because a wallet designed interface-first is a liability with good typography.
Recovery treated seriously
Recovery flows are designed and tested as rigorously as signing itself, since lost access is the most common user catastrophe.
Honest transaction UX
Simulation, human-readable previews, and clear fees, so users know what they sign instead of clicking through warnings.
Institutional patterns available
MPC, HSM, policies, and audit trails for custody products that must survive compliance scrutiny, not just app store review.
Track record since 2010
9,000+ projects and 3,900+ apps across 25+ countries, held to the same delivery bar as everything else.
