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.

Will our contracts be ready for a third-party security audit?

We build with an audit-first mindset — static analysis, fuzz testing, and manual review happen before code goes to an independent auditor, and we remediate every finding before mainnet.

Can you connect our token or exchange platform to banking rails?

Yes, we integrate crypto on/off-ramp providers and traditional payment rails behind a single checkout or wallet experience.

How do you secure custody funds?

Multi-layer hot/warm/cold wallet architecture, multi-sig approval, and HSM-backed key management, the same approach we use for licensed exchange clients processing nine-figure monthly volume.

Which chains and standards do you build on?

Ethereum, Polygon, BNB Chain, Solana, Tron, Avalanche, and permissioned frameworks, using ERC-20/721/1155, BEP-20, and SPL standards depending on your target market.

Crypto & Web3 Software Development in Vietnam

Exchanges, token issuers, and Web3 platforms need production-grade blockchain engineering — not prototype code — to survive audits, scale to real transaction volume, and integrate cleanly with fiat rails. In Vietnam, that means building to the 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 crypto & web3 businesses 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

What crypto & web3 operators struggle with

Contracts that won't survive an audit

Prototype-stage smart contracts with no formal testing routinely fail third-party security review, blocking funding, listings, or mainnet launch.

No bridge to fiat rails

Token and exchange platforms that can't cleanly connect to banking and card rails lose users at the on/off-ramp step.

Custody risk at scale

Manual or under-engineered key management is the single largest cause of exchange and wallet fund losses.

Gas costs and throughput ceilings

Poorly optimized contracts and undersized infrastructure make transactions expensive and slow as adoption grows.

Our Approach

How we support crypto & web3 in Vietnam

Production-grade token & smart contract development

ERC-20/721/1155, BEP-20, and SPL contracts built with checks-effects-interactions patterns, reentrancy guards, and formal test coverage before any audit.

Independent audit coordination

We prepare documentation and test coverage and remediate findings alongside leading third-party audit firms before mainnet deployment.

Exchange, wallet & custody infrastructure

Low-latency matching engines and hot/warm/cold custody architecture with multi-sig and HSM-backed key management.

Fiat-to-crypto rail integration

Crypto on/off-ramp providers wired into existing checkout and wallet flows alongside traditional payment rails.

Gas optimization & Layer-2 architecture

Storage packing, batch operations, and rollup/sidechain selection engineered around your actual throughput and cost targets.

FAQ

Crypto & Web3 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.
