Blockchain Development for the US, Europe & India

A shared ledger is useful only when the product needs its particular ownership or verification model. MynTech Software scopes smart contracts, wallet connections and supporting web applications around the transaction you need to support. We first compare that approach with a conventional database and API, including operational cost and the handling of errors.

The demo runs on a test network so your team can inspect permissions, transaction behaviour and wallet interactions without treating it as a production launch. Contract review, deployment ownership, network fees and any independent security audit are planned as separate parts of the delivery scope.

See Your Software Working — Before You Pay

We agree what the demo will cover, then build it for your team to test before the first payment. Use the review to confirm the product direction and acceptance criteria. The written proposal sets out what is included in the demo, the production work that follows, and the payment milestones.

What We Build

📜

Smart Contracts

Solidity contracts for payments, escrow, vesting and business logic, with testing and a security-review plan agreed in the scope.

🌐

dApp Development

Full decentralized applications with wallet connection, on-chain logic, and polished web frontends.

🪙

Tokenization

Token and ownership workflows with explicit permission, upgrade and security requirements; legal requirements need separate review.

🔗

Web3 Integration

Add wallet login, crypto payments, or on-chain verification to your existing web or mobile product.

📦

Supply Chain & Records

Immutable audit trails for provenance, certification, and document verification.

🛡️

Audit & Rescue

Security review of existing contracts and takeover of stalled Web3 projects.

Frequently Asked Questions

How much does blockchain development cost?

A blockchain estimate depends on contract complexity, wallet support, frontend and backend work, security review and deployment requirements. Network fees and independent audits may be separate costs. We define the test-network demo and the work needed for production before issuing a project quote.

Do we actually need blockchain for our use case?

Maybe not — and we will tell you honestly. In your free discovery call we assess whether a conventional database serves you better. Clients trust us because we recommend against blockchain when it adds cost without value.

How do you handle smart contract security?

The scope defines contract tests, dependency review, static analysis and test-network acceptance checks. Where an independent audit is needed, its provider, cost and remediation process are agreed before production deployment. A tested dependency does not make a new contract automatically audited.

Can you add crypto payments to our existing app?

Yes. We integrate wallet-based payments, stablecoin checkout, and on-chain verification into existing web and mobile products without disrupting your current users.
