Enterprise Blockchain & Secure Assets

Premium engineering for modern decentralized ecosystems, bringing transparency and security to your digital architecture.

Fixed-scope · quoted upfront
$400 – $1,500
2–3 weeks
dApp Development

Connect your existing business frontend to secure, on-chain logic. This allows for verifiable, tamper-proof user interactions and secure digital wallet connections without compromising the modern user experience.

$500 – $10k+
Scoped per contract
Smart Contract Development

Deploy secure, programmable agreements that execute automatically when conditions are met. Ideal for establishing tokenized loyalty programs, transparent voting systems, and automated royalty or asset distributions.

Who this is for

  • 01

    Web3 founders needing a production dApp connected to real user wallets without shipping a broken UX.

  • 02

    Established businesses launching tokenized loyalty, on-chain voting, or verifiable ownership features.

  • 03

    Existing crypto projects with a working contract but a frontend that does not match the ambition.

What you get

  • Audited, deployed smart contracts on your target chain (EVM: Base, Ethereum, Polygon, etc.)
  • Full-stack dApp with wallet connect, transaction states, and error handling that does not feel like 2018
  • Verified contract source on the block explorer
  • Test suite with coverage report and gas usage documentation
  • Deployment scripts + runbook so your team can redeploy or upgrade later

How it works

01
Architecture

Threat model, upgrade strategy, and gas-cost estimate agreed before any Solidity is written.

02
Contract build

Contracts written with tests first, reviewed against known attack vectors, deployed to testnet.

03
Frontend integration

React dApp built against the testnet contract with proper transaction UX and wallet state handling.

04
Mainnet + verification

Coordinated deployment, source verification, and a signed-off runbook.

What changes

  • → Result 01

    A dApp your users can actually navigate — no unexplained loading spinners or failed transactions

  • → Result 02

    Contracts documented and tested well enough for a third-party audit to move fast

  • → Result 03

    On-chain features that reinforce your existing product instead of replacing it

FAQ

Which chains do you support?+
Primarily EVM-compatible: Base, Ethereum L1, Polygon, Arbitrum, Optimism. Non-EVM chains available on request after scoping.
Do you handle the audit?+
I write audit-ready code with tests and documentation. I coordinate the third-party audit but the audit itself is a separate contract with the auditor of your choice.
Can you integrate with an existing contract?+
Yes — a common engagement is 'the contract is fine, the frontend is not'. I build the dApp on top of what you already deployed.
What about upgradability?+
Discussed in the architecture step. I ship upgradeable proxies when it fits and immutable contracts when it does not — with the trade-offs documented in writing.
Is $500–$10k+ really the smart-contract range?+
Yes. A single utility token is closer to $500. A staking + governance + treasury system is closer to the top of the range. Scoped upfront before any commitment.
