Smart contracts and the apps around them

LinkIT builds Web3 systems — smart contracts, token-gated products, wallet flows, indexers, and dashboards — with security and monitoring planned before launch.

What we do

Smart contracts and connected applications

LinkIT builds smart contracts, wallet flows, token-gated products, indexers and on-chain dashboards. Access controls, adversarial tests, monitoring and a tested upgrade or migration path are planned before launch.

From a wallet action to a usable product
  1. 01

    Define the rules

    Set permissions, state changes and failure cases before implementation.

  2. 02

    Connect the application

    Show approvals, signature requests and transaction states in the interface.

  3. 03

    Prepare for production

    Test adversarial cases and prepare monitoring and external audit review.

Audit readiness supports an external review; it is not a claim of an independent security audit.

Explore the studio’s work

LinkIT builds smart contracts and the applications that use them, including wallet interactions, indexing, dashboards, and operational monitoring.

What we build

The scope can include smart contracts, token-gated products, wallet flows, indexers, and on-chain dashboards. We define how the application interacts with the contracts and handles failures.

Security and audit preparation

We plan permissions, monitoring, and any upgrade or migration path before deployment. Tests cover adversarial inputs, edge cases, and dependency failures as well as expected behavior.

Wallet interactions

We review connection, chain selection, approvals, signatures, rejected requests, and transaction feedback from the user’s perspective.

Before we build

Good questions.
Clear answers.

A little more about the work, the scope, and what to expect.

Do you write and test smart contracts?

Yes — primarily in Solidity. We write adversarial tests for reentrancy, edge cases, and dependency failures, and prepare the implementation and documentation for independent audit.

Can you build the app around the contract too?

Yes. The scope can include wallet interactions, indexers, dashboards, and the web app alongside the contract.

How do you handle security?

We plan access control, monitoring, testing, and any upgrade or migration path before launch. Independent audit remains a separate review step.
