Do you integrate with Vietnamese e-wallets and QR payment rails?

Yes, we integrate leading Vietnamese e-wallet and QR payment methods alongside card and bank transfer rails within a unified orchestration layer.

What's the difference between custodial and non-custodial wallets?

Custodial wallets hold private keys on your behalf with easier recovery; non-custodial wallets give users full control of their private keys.

Which blockchains can the wallet support?

Bitcoin, Ethereum and EVM-compatible chains, Solana, Tron and others based on your product's needs.

Can the wallet include staking or in-app swaps?

Yes, staking, swap and on/off-ramp features are common additions we build directly into the wallet.

How long does it take to build an MVP wallet?

A focused MVP wallet typically launches in 8–12 weeks; a full-featured multi-chain wallet with swap and staking takes longer.

Cryptocurrency Wallet Development in Vietnam

Generic wallet apps rarely fit a specific product's compliance model or user experience needs. Hurain Technologies builds custodial, non-custodial, hybrid and smart-contract (ERC-4337) crypto wallets tailored to exchanges, Web3 platforms, gaming ecosystems and remittance products — with multi-chain support, in-app swap/staking, and full white-label branding. In Vietnam, that means building to the technical expectations of Asia-Pacific: Payment intermediary services, including e-wallets, require a license from the State Bank of Vietnam (SBV) under its intermediary payment services framework.

Vietnam Regulatory Landscape

What wallet development buyers in Vietnam need to know

Payment intermediary services, including e-wallets, require a license from the State Bank of Vietnam (SBV) under its intermediary payment services framework.
Vietnam does not currently recognize cryptocurrency as a legal means of payment, and its broader digital asset legal framework remains under active development.
Foreign exchange and cross-border payment activity intersects with SBV foreign exchange management regulations.
We build to current SBV payment licensing expectations and treat digital-asset features conservatively given the evolving legal landscape, alongside Vietnamese regulatory counsel.

The Challenge

Problems we see teams struggling with

Limited wallet options for your product

Off-the-shelf wallets don't match your compliance model, supported assets, or UX requirements.

Custody security and key management

Keys must be secured on-device or on your infrastructure without exposing users to loss.

Multi-chain complexity

Supporting multiple blockchains from one wallet interface multiplies engineering effort.

User recovery and support friction

Seed phrase recovery is user-hostile; social recovery and secure enclave options solve this.

Poor UX driving support ticket volume

Confusing transaction confirmations, unclear gas fee estimates, and cryptic error messages generate a disproportionate share of support load for consumer wallet products.

App store and platform compliance friction

iOS and Android have specific, evolving policies around crypto wallet apps that can delay or block a launch if not planned for early.

Our Approach

How we deliver wallet development in Vietnam

Custodial wallets

You hold keys on secure infrastructure; users get login-based ease of use.

Non-custodial wallets

Users hold their own keys with seed phrase, social recovery, or secure enclave-backed biometrics.

Smart-contract wallets (ERC-4337)

Account abstraction enables gasless transactions, spending limits, and social recovery without sacrificing security.

FAQ

Wallet Development in Vietnam — FAQ

Vietnam does not yet have a comprehensive legal framework recognizing crypto as a payment instrument, so we recommend confirming scope with Vietnamese legal counsel first; most of our Vietnam work focuses on SBV-licensed payment and API infrastructure instead.
