Anyone can promise secure. Security you can measure.
Enterprise crypto wallet development the evaluation-led way: key management, policy engines, and AI-assisted risk controls, with the security posture graded before we build and re-graded before anything ships.

The short answer
Updated July 2026
Houtos Labs builds enterprise crypto wallets and custody systems the measured way. Multi-chain architecture — Ethereum, Base, Solana, Bitcoin rails, Stellar, XRPL — behind one key-management and policy layer, with AI-assisted risk controls that inform signers but never sign, and a security posture that's graded before we build and re-graded before launch.
The same evaluation-led discipline as the rest of the studio: a published rubric, plain-language findings, and estimates never dressed as measurements. Work is labeled by its real status in the Registry. Adjacent practices: web3 commerce and business agents.
The security posture, simulated
Custody security isn't a feeling — it's a stack of controls that either exist or don't. Flip the controls and watch the posture respond. This is the reading we run on real wallet projects, in miniature.
Build the vault
Six controls, all defaulted off — the posture of a hot wallet with good intentions. Turn them on and earn the grade.
Hardened. Keys split, policies enforced, watch running — the state we ship custody in.

What our wallet development covers
From a customer-facing wallet to an internal treasury desk — designed, engineered, and graded in-house.
View the architecture sketch — keys, policy gate, chains, monitoring
Multi-chain wallet architecture
One key-management and policy layer across EVM chains, Solana, Bitcoin rails, Stellar, and XRPL — so adding a chain never means rebuilding your security model. Chain choice follows your users, not fashion.
AI-assisted risk controls
Anomaly flags, address-risk screening, human-readable transaction explanations, routing suggestions. AI informs; deterministic policy decides; humans sign. Probabilistic outputs are labeled as such — the same honesty rule as our reports.
Enterprise controls & custody UX
Approval flows, spending limits, role separation, audit trails — and interfaces that make the safe action the easy action, for treasurers and customers alike.
Hardening & the audit pass
Already running a wallet or DeFi surface? We grade the posture, hand you a prioritized plain-English fix list, do the work if you want it done, and re-grade. For formal contract audits we work alongside specialist auditors — honest scope is part of the security.
The vault holds because the math does.
Keys split · policies enforced · posture measured — before a single asset moves
Proof, honestly
The standing rule holds here too: chain coverage above is an architecture claim, not a deployment claim — shipped work sits in the Registry labeled by its real status, and an estimate is never dressed as a measurement. In custody, that honesty isn't branding. It's the security model.
Work, labeled as it is

Fair questions
What does enterprise crypto wallet development include?
Key management architecture (MPC, multisig, or hardware-backed signing), policy engines (limits, allowlists, approval flows), chain integrations, transaction construction and simulation, monitoring and alerting, and the interfaces your team and customers actually use. At Houtos Labs it also includes what most vendors skip: a measured security-posture baseline before we build and a re-grade before anything ships.
Which blockchains can a multi-chain wallet support?
We architect for EVM chains (Ethereum, Base and other L2s), Solana, Bitcoin rails, Stellar, and the XRP Ledger — behind one policy and key-management layer, so adding a chain doesn't mean rebuilding your security model. Which chains make sense depends on where your users and assets actually are; that's a scoping conversation, not a checkbox.
How does AI make a crypto wallet safer?
Applied narrowly and honestly: anomaly flags on unusual transaction patterns, address-risk screening before signing, human-readable transaction explanation so signers know what they're approving, and routing suggestions. AI assists the controls — it never replaces deterministic policy rules, and it never signs. Anything probabilistic is labeled as such, the same way our reports label estimates.
Do you audit or harden existing wallets and DeFi platforms?
Yes. Hardening starts with a reading: we map the key paths, permissions, dependencies, and operational practices, grade the posture, and hand you a prioritized fix list in plain English. Then, if you want, we do the work and re-grade it. For formal smart-contract audits we work alongside specialist auditors rather than pretending to replace them — honest scope is part of the security.
Custody you can hold to a number.
