Build a secure, scalable crypto wallet without guesswork
The development partner founders pick when they want it built right the first time. Multi-chain, MPC and account abstraction, custodial or non-custodial, shipped in 6 to 10 weeks.
Still deciding on a key-management model or scope? We will walk you through it on a short call.
Book a 30-min architecture review →The frustrating truth about building a crypto wallet
When you are building a wallet, four things are true at once, and they pull against each other.
→ You can't risk security. One key leak and it is over.
→ You can't compromise on speed. A laggy wallet loses users in a day.
→ You can't depend on freelancers. They build fast, ship broken, and vanish.
→ You can't just hope it won't break. Hope is not an architecture.
You are excited, and you are also a little overwhelmed. Too many chains. Too many security layers. Too many people telling you different things. And somewhere in the middle, the project stops moving. It does not have to be this complicated.
First, who holds the keys?
Every wallet starts with one choice, and most vendors skip the conversation.
| Model | Who controls keys | Best for | Tradeoff |
|---|---|---|---|
| Non-custodial | The user | Web3-native apps, self-sovereignty | User loses keys, funds are gone; recovery design matters |
| Custodial | You (the operator) | Fintech apps, exchanges, regulated flows | You hold liability and need custody-grade security |
| MPC | Split across parties | Best of both, no single point of failure | More complex to build and integrate |
| Account abstraction (ERC-4337) | Programmable (smart accounts) | Gasless UX, social recovery, session keys | Newer standard, needs careful implementation |
We help you pick during the architecture review, based on your users, your regulatory position, and your risk tolerance. Most modern wallets we build land on MPC or account abstraction, often together.
Security at every layer, not just the headline
→ Key management
MPC or smart-account architecture, hardware-backed where it fits, with a real recovery design (not just a seed phrase and a prayer).
→ Contracts
Wallet and account-abstraction contracts audited before launch (see our smart contract audits →).
→ Application
Encrypted storage, secure enclaves on mobile, biometric and device binding.
→ Infrastructure
Hardened nodes, rate limiting, anomaly detection, and alerting.
Wallet types we build

Why teams choose us
→ Senior blockchain engineers
Shipping on Ethereum, Solana, and Hyperledger since 2014, not learning on your budget.
→ End-to-end product thinking
We care about retention and UX, not just whether the contract compiles.
→ Security at every layer
Audited contracts, hardened infrastructure, real recovery design.
→ Straight communication
Regular updates, clear timelines, and honest feedback when a feature is a bad idea.
We don't just build apps, we build confidence.
Frequently asked questions
It depends on your users and regulatory position. Fintech and regulated flows often go custodial or MPC; Web3-native apps lean non-custodial or account abstraction. We decide together in the architecture review.
Most builds ship in 6 to 10 weeks. White-label is faster; custom key management and multi-chain support add time.
The contracts are, before launch, using our five-layer audit process.
Ethereum, Base, Arbitrum, Optimism, Polygon, Solana, and others on request.
You do, from day one. NDA on request.
Yes. We build ERC-4337 smart accounts with session keys, social recovery, and sponsored gas.
