01 — What this covers

Scoped per contractWeb3 & Blockchain

The on-chain logic itself: tokenized programmes, voting, royalty splits, verified ownership. Written test-first, reviewed against known attack patterns, and deployed with the source verified so anyone can check it.

  • Threat model, upgrade strategy and cost estimate agreed before any code
  • Test suite with coverage report and documented transaction costs
  • Deployed and source-verified on the public explorer
  • Deployment scripts and runbook so your team can redeploy or upgrade later

02 — How it works

Threat model and scope
01

Threat model and scope

Before any code, we agree what must never happen: funds stuck, the wrong person minting, rules changed silently. Whether the rules can be upgraded and who is allowed to do it gets written down, along with the cost estimate.

Write and test
02

Write and test

The contract is written test-first and reviewed against known attack patterns. You get a coverage report, documented transaction costs, and a run on a test network before anything touches real money.

Deploy and verify
03

Deploy and verify

Deployed on your target chain with the source verified on the public explorer so anyone can check it, plus deployment scripts and a runbook so your team can redeploy or upgrade later.

04 — FAQ

We want loyalty points, memberships, or proof of ownership. Where does that live?+
In the contract. It records who owns what and enforces the rules automatically, points, tiers, voting, royalty splits, so nobody has to be trusted to keep a private spreadsheet honest.
How do you keep it safe?+
Before writing anything, we agree what must never happen: funds stuck, wrong person minting, rules changed silently. Every rule gets an automated test, we run it on a test network first, and the code is published so anyone can verify it.
Do I need a separate audit?+
For anything holding real money, yes. I write the code and documentation so an external auditor can move quickly, and I coordinate with them, but the audit itself is a separate engagement with the auditor you choose.
Can the rules be changed later?+
That is decided upfront, not discovered later. Whether the contract can be upgraded, and who is allowed to do it, is written down with the trade-offs before any code exists.
How long does it take?+
Scoped per contract, because a points system and a royalty split are not the same job. You get the timeline, the threat model and the cost estimate in writing before work starts.
