Blockchain & Web3

The on-chain layer is the part you cannot patch later. We design and build the contracts, the interfaces, and the plumbing that makes a blockchain product usable by someone who has never heard the word ABI.

/ service · 01 — what we ship

What this covers

Most blockchain projects fail in one of two places. The contracts are correct and nobody can use them, or the interface works and the contract has holes in it. We work both sides in the same engagement, with the same people, because a contract that nobody can safely call is not finished.

Smart contract development

Solidity, and Rust/Anchor where the ecosystem demands it

Tokenisation platforms

asset-backed tokens, on-chain registries, transfer and compliance logic

dApps and wallet interfaces

front ends wired to real contract state, not mocked state

On-chain / off-chain integration

step 01

Contract design before frontend.

We sketch the state machine and enumerate the failure modes on paper before a line of Solidity exists. Anything ambiguous at this stage stays ambiguous forever.

step 02

Test coverage as a floor, not a target.

Unit, fuzz, and invariant tests run in CI from the first commit. We do not call a contract done when the happy path passes and someone is watching.

step 03

Deployment as a rehearsed step.

Testnet, then a migration rehearsal against a mainnet fork, then mainnet. The upgrade path gets tested before it carries value.

step 04

Observability from day one.

Event indexing, alerting on state transitions, and a dashboard that shows what the contract is actually doing rather than what we hoped it would do.

step 05

Handover with the keys.

You get contracts, ABIs, deployment scripts, and a runbook. We do not hold the only copy of anything.

/ service · 03 — what you get

What you get on delivery

Audited or audit-ready contracts, with the Foundry/Hardhat suite included
Full test suite and a coverage report you can show a funder
Deployment scripts and a verified upgrade path
ABI and integration docs written for a developer who did not build it
Event indexer configuration and monitoring dashboards
A runbook covering the failure modes you will actually hit

/ service · 04 — the honest part

What we will tell you honestly

If your project does not need smart contracts, we will say so before you spend money proving it. A well-built backend and a good interface will beat a clever contract in almost every case where the contract is not the product. We would rather lose the scope than win the wrong engagement.
