Short answer
Choose a Web3 development partner on evidence: shipped projects on the chains you need, independently audited smart contracts, a product and design process beyond code, experience with KYC and compliance where your market requires it, and a clear plan for support after launch. Ask for a case study for each.
What to look for in a Web3 development partner
Choose a Web3 development partner on evidence, not on a polished website. Look for shipped projects on the chains you need, independently audited smart contracts, a team that thinks about product and compliance as well as code, and a clear plan for support after launch. Ask for proof of each, then check it yourself. The checklist below shows what to ask for and what a weak answer looks like.
The stakes are real. Smart contracts are hard to change once deployed, and mistakes cost money. Immunefi counts about $11.9B lost to 425 hacks over five years, as reported by The Block. A good partner helps you stay off that list.
The checklist
| Check | Ask for | Warning sign |
|---|---|---|
| Shipped work | Live projects you can open, with on-chain activity you can verify | Only screenshots and mock-ups |
| Chain fit | Reasons for choosing a chain based on your cost, speed and users | One favourite chain for every project |
| Contract security | Internal review plus an independent audit, with the report shared | "We test it ourselves" and nothing else |
| Audit readiness | Tests, documentation and a frozen version before audit | No tests, or code that changes during the audit |
| Compliance | Experience with KYC, AML and the licences your market needs | "Compliance is your lawyer's job" |
| Product thinking | Help with scope, user flows and token design, not only code | Builds exactly what is asked, with no questions |
| Communication | Weekly demos, shared repositories and a named lead | Updates only when you chase |
| Ownership | You own the code, keys and accounts from day one | Code or admin keys held by the vendor |
| After launch | A support window, monitoring and an incident plan | The engagement ends at deployment |
Technical checks
Multi-chain experience
The right chain depends on your use case. Ethereum mainnet suits high-value settlement. Solana suits high throughput. Layer 2s such as Arbitrum and Optimism suit low fees on Ethereum. A good partner explains the trade-offs for your product and does not push one answer.
Smart contract quality and audits
Your partner should write in the language your chain uses (Solidity, Rust or Move), follow established practice such as OpenZeppelin's contract library and ConsenSys's best practices, and keep contracts small and modular. Ask how they prepare for an independent review. Our guide to smart contract audit cost explains what an audit covers and what moves the price.
Compliance built in
If you handle customer funds or onboard retail users, compliance shapes the design. Ask about identity checks (providers such as Sumsub or Veriff), transaction monitoring (such as Chainalysis), fiat on and off ramps, and the licensing in your markets, for example VARA in Dubai. Our post on crypto and Web3 business ideas for 2026 summarises the rules in five markets.
Product and delivery checks
- Speed to a first version. A good partner can reach a testnet version in weeks, with clear sprints and scope control. Our guide to how to build an MVP covers the steps.
- Token and incentive design. If your product has a token, ask who designs the supply, vesting and utility. Our guide to tokenomics explains the basics.
- Transparency. Weekly demos, access to the repository and deployment scripts, and a fast channel for questions.
- Proof of work. Mainnet projects, live dashboards, audited contracts on GitHub and references you can call.
Questions to ask in the first call
- Which of your projects are live on mainnet, and can I speak to the client?
- Who audited your contracts, and can I read the report?
- How do you choose a chain for a new project?
- What happens if a critical bug is found after launch?
- Who owns the code, the keys and the cloud accounts?
- How do you handle KYC and compliance for the markets I serve?
At Avinya Labs we answer these with delivered work: a centralized crypto exchange with 99.9% uptime since launch, and a smart contract audit and deployment with zero critical findings. You can see the full Web3 development service and book a call to test us against this list.

Frequently asked questions
What should you look for in a Web3 development partner?
Shipped projects you can verify, independently audited contracts, experience with the chains and compliance rules you need, a product-led approach and clear communication and ownership terms.
Which blockchains should a Web3 development partner support?
At minimum Ethereum and its main Layer 2s, plus a high-throughput chain such as Solana or BNB Smart Chain. The right choice depends on your volume, cost sensitivity and users.
How much does Web3 development cost?
It depends on scope. A contract-only MVP costs far less than a full product with compliance tooling and several chains. A smart contract audit with us starts from about USD 1,000 and rises with scope and complexity.
What is the difference between an MVP and a full blockchain product?
An MVP proves the core mechanism with minimal infrastructure. A full product adds compliance, monitoring, more chains and the polish a wider audience expects.
Should I own the smart contract code and keys?
Yes. Agree in writing that you own the code, deployment keys and accounts from day one, and that the partner holds no admin access you cannot revoke.
