Crypto wallets

Custody is a product decision—not an implementation detail

Wallet projects fail when nobody agreed who holds keys, how recovery works, or what happens if a user loses their device. NASBIX builds wallet experiences—standalone apps or embedded in your Web3 product—with architecture legal and security can review before users deposit real funds.

We deliver on iOS and Android via Flutter or native stacks, plus web and in-app embedded wallets (email, passkey, or social onboarding) when friction must drop. Chain support, indexing, and contract interaction pair with our blockchain team; we do not treat wallets as thin wrappers over a single RPC endpoint.

Custodial, non-custodial, and MPC trade-offs documented for stakeholders upfront
Transaction previews: recipient, asset, fee, and contract call clarity before sign
Secure enclave, keystore, and seed phrase flows with backup verification steps
Multi-chain balances and history via indexers—not N+1 RPC from the client

Who we help

Built for products where keys are the brand promise

Wallet apps, embedded onboarding, and exchange-adjacent custody—scoped to your regulatory posture.

Standalone wallet apps

Consumer wallets with portfolio, send/receive, and optional swap—store-review-ready security narratives.

Embedded & smart wallets

Enterprise & custodial

Role-based treasury, approval flows, and audit logs when ops—not end users—control policy.

What you get

Wallet capabilities that matter

Scoped to chains, custody, and compliance—not a cloned open-source repo without hardening.

Custody architecture

Key generation, storage, rotation, and HSM/MPC integration paths matched to your model.

Onboarding & recovery

Seed backup, social recovery, passkeys, and account export policies users can follow.

Transaction UX

Send, receive, QR, address books, fee selection, and human-readable contract interactions.

Multi-chain portfolio

Asset aggregation, NFT views, and chain switching with consistent address display rules.

Swaps & dApp browser

Integrations with DEX aggregators or in-wallet dApp surfaces—allowlisted and previewed.

Backend & ops

Notification services, KYC hooks where required, admin tools, and incident response playbooks.

Security-first wallets

Depth that assumes attackers will target your users

Wallets are high-value targets—we threat-model phishing, clipboard hijack, jailbreak/root, and supply-chain risk before feature velocity wins.

Secure coding for mobile keystore, biometrics, and anti-screenshot policies where needed
Certificate pinning, jailbreak detection, and obfuscation scoped to threat level
Transaction simulation and domain binding for in-app dApp and WalletConnect sessions
Penetration testing coordination with NASBIX security practice
Compliance touchpoints: travel rule, KYC/AML integrations when custodial
Alignment with secure SDLC and key ceremony documentation
