What is Smart Contract, and why do companies build with it?
Smart contracts are programs deployed to a blockchain that execute automatically and cannot be altered once live. That immutability is the point and the risk: a logic error cannot be patched the way a web service can, so smart contract engineering is closer to safety-critical software than to typical application development.
What is Smart Contract used for?
These are the product categories where Smart Contract is the deliberate choice rather than a default. If your project sits outside them we will say so during the first call.
DeFi protocols
Lending, staking, swaps and yield mechanisms.
Token systems
Issuance, vesting and governance logic.
NFT and digital assets
Ownership, royalties and marketplace rules.
Supply chain and provenance
Verifiable records shared between parties.
Security review
Auditing and hardening existing contracts.

How do you evaluate a Smart Contract developer?
Ask a smart contract developer to name attack classes they defend against — reentrancy, oracle manipulation, access control errors, integer issues — and how they test for them. Ask what invariants they write and whether they have been through an external audit. Fluency in Solidity is common; security discipline is the differentiator.
We apply exactly these checks before a candidate reaches your shortlist, which is why our acceptance rate sits at roughly 3%. You still run your own interview — the screen is there to make that interview short.
How deep is the Smart Contract talent pool in Vietnam?
Vietnam produces a large annual cohort of computer-science and engineering graduates, and Smart Contract sits inside the mainstream of what local teams build commercially — which matters, because a stack that is only used in hobby projects produces candidates with no production scars. Depth is strongest at mid level (three to five years); genuine senior and lead-level people exist in smaller numbers and are almost always employed, which is why we approach them directly rather than waiting for applications.
Practically, that shapes two things for you. First, timing: mid-level roles are usually filled from our existing pool within 48 hours, while a rare senior specialisation can take two to three weeks of targeted search. Second, price: seniority moves the rate far more than the technology does, which is why our ladder is built on experience bands rather than on a per-language price list. If your requirement is genuinely scarce locally, we will say so at the first call instead of sending profiles that do not meet the bar.
What to prepare before your Smart Contract developer starts
The difference between an engineer who contributes in week one and one who is still waiting in week three is almost never the engineer. It is access. Before the start date, have repository and environment access approved, a named person who can answer domain questions, and one small but real ticket ready — not a sandbox exercise, an actual piece of work that goes through your normal review and release process.
- Accounts, repository and environment access approved in advance
- A named technical contact for the first two weeks
- Architecture notes or a walkthrough recording, however rough
- One small, real ticket ready for the first week
- Your definition of done and review expectations written down
We run this checklist with you before the start date as part of onboarding, and we hold a 30-day review covering delivery, communication and fit — with a free replacement if any of the three is wrong.
How much does it cost?
Rates are all-in: sourcing, five-step vetting, employment contracts, payroll, personal income tax, statutory insurance, workspace and delivery management are already included. There is no separate recruitment fee and no hidden employer-cost surprise at the end of the month.
What moves the number is seniority, how scarce the skill set is locally, and engagement length — longer commitments and multi-role teams price better than a single short contract. You receive a written quote against your specific role profile before committing to anything.
How do you get started?
- Day 0 — send the briefRole, seniority, stack and timeline. A 20-minute call is usually enough.
- 48 hours — shortlistProfiles with real project context and confirmed availability, not keyword-matched CVs.
- ~7 days — startYou interview and select; we handle contracts, payroll, compliance and onboarding.
Smart Contract: in-house, freelancer or TechHub?
| Criteria | In-house hiring | Freelancer | TechHub |
|---|---|---|---|
| Vetting | You run it | Self-declared | Top 3%, five-step screen |
| Time to start | 2–3 months | Days, quality varies | ~7 days, vetted |
| If it goes wrong | Costly to unwind | You start again | Free replacement in trial |
| Payroll & compliance | Your overhead | Your risk | Handled in Vietnam |
| IP assignment | Yours | Often unclear | Contractual, yours |
| Continuity | Depends on retention | None | Managed, with backfill |
What the engagement feels like day to day
Your engineer joins your standups, works in your repository and follows your definition of done. A named account lead handles anything commercial so your technical leads never have to negotiate — they just get an engineer who shows up, communicates in English and closes tickets.
- In your tools, your process, your ceremonies
- Written daily updates where teams are distributed
- Monthly delivery and retention review
- Scale up, scale down or replace on agreed notice
