Blockchain
& Smart Contracts
Build smart contracts and connect them to wallets, applications, and data services. Define the rules, test the important properties, and prepare the system for operation.
The work
Connect contract rules to a working product.
Contracts and business rules
Implement agreed contract rules for allocations, vesting, escrow, permissions, and upgrades.
Wallets and product integration
Connect signing, transaction status, indexing, and backend services to your application.
Contract testing and operation
Test important properties and prepare release controls, monitoring, and technical handover.
Experience and delivery scope
Agree the business rules, users, chain, assets, and acceptance checks before development. A first engagement can review an existing contract or build one bounded workflow with its application integration.
The founder’s résumé records Pact contracts, wallet and node work at Hypercent, and a Solidity application at TailPath. These are roles held by the founder. The illustrative workflow below describes a proposed engagement; it makes no claim of an independently audited protocol.
Blockchain engineering scope
Contracts and business rules
Design and implement token distribution, vesting, escrow, permissions, and agreed upgrade behavior. Scope the work to the selected language and chain, including Solidity/EVM or Pact when suitable.
Wallets and product integration
Connect signing, transaction status, chain data, APIs, and backend jobs to the product. Define confirmation requirements, failed transactions, reorganizations, and recovery. Record which party controls each key.
Contract testing and operation
Test permissions, state transitions, failure paths, and agreed contract properties. Prepare versioned deployment instructions, administrative controls, monitoring, and handover. A separate security review can assess the agreed revision before release.
Illustrative workflow
Token distribution & vesting
- 01
Specify the allocation
Record recipients, amounts, dates, and administrative powers.
- 02
Implement and test
Test release schedules, permission checks, and failed claims.
- 03
Connect the product
Show wallet transactions, confirmations, and available balances.
- 04
Review and hand over
Record the reviewed revision, release procedure, and remaining risks.
Illustrative engagement. Chain, custody, security review, and release authority are agreed for each project. This example does not claim an audited deployment.

Before we start
Which chains and languages can be included?
We scope the work to the selected platform. Relevant founder experience includes Solidity and Pact. Chain support, integrations, and review methods are agreed before work begins.
Can you review existing smart contracts?
Yes. Start with a defined revision, intended behavior, dependencies, and threat model. Security findings and remediation retesting are scoped through Security Testing & Investigations.
Does every project need a blockchain?
We first assess shared control, verification, and operating requirements. The recommendation can be a conventional database or signed record system when it meets the goal more simply.
