Blockchain & Web3
On-chain work is ordinary engineering with an unusual failure mode: a deployed contract cannot be patched, and a lost key cannot be reset.
Wallet integration, token and NFT contracts, on-chain data indexing, and bridging chain state into ordinary business systems.
What we do
Blockchain & Web3
We handle wallet integration, token and NFT contracts, and the indexing layer that turns chain events into data an ordinary application can query without hitting a node on every page load.
Contracts are written to be reviewable: scoped, documented, tested against the failure cases, and deployed to a testnet with the exact same script that will run on mainnet. Upgrade and ownership decisions are agreed with you before deployment, not assumed.
The part most projects underestimate is the bridge back to normal systems: reconciling on-chain state with your own database, and handling the window where a transaction is submitted but not yet final. We build that explicitly.
Blockchain & Web3
What you get
Wallet connection and signing flows with clear states for pending and failed
Token or NFT contracts, tested and deployed through a repeatable script
An event indexer so your application queries a database, not a node
Reconciliation between on-chain state and your own records
Key custody and upgrade decisions documented and agreed before deployment
Our Expertise

How we work
How a project starts, and how it is priced
Tell Us The Problem
Reach us by email or WhatsApp and describe what is broken or what you want built. We reply with our reading of the problem and the options.
Get Scope And Price
You receive a written scope, a timeline and a fixed price, including what is explicitly not included. No surprise line items later.
We Build And Hand Over
We deliver on the agreed timeline, with documentation and a working deployment. You can keep us on for support, or take it in-house.
How pricing works
The price follows the scope. Once we understand the problem, you receive a written quotation that states what is included, what is explicitly not included, the timeline and the price.
If something outside that scope turns up during the work, we write it down and tell you before anything changes. Extra work is quoted separately and only starts once you agree to it.
You can also stop after the quotation. Reading our scope does not commit you to building with us.
FAQ
Questions buyers ask us
How is a blockchain project priced?
From the scope: the contracts, the wallet flows, the indexer and the reconciliation with your own records. Testing against failure cases and a testnet deployment with the same script as mainnet are written into that scope. You receive it in writing with a fixed price before work starts.
How long does it take?
The timeline is written into the quotation. Contracts go to a testnet first with the exact script that will run on mainnet, and that testing window is planned in, because a deployed contract cannot be patched afterwards.
Who owns the contracts and the keys?
Key custody, contract ownership and upgrade rights are documented and agreed with you before deployment, not assumed. Ownership of the off-chain source code is agreed in the quotation before work starts.
What happens after the contracts are live?
The contracts themselves do not change unless an upgrade path was agreed. The indexer, the application and the reconciliation keep running, and managed service covers monitoring, incidents and small changes to them. Or your team takes them over with the documentation.
Can a deployed smart contract be fixed?
Not by patching it. That is why contracts are scoped, documented and tested against their failure cases before mainnet, and why any upgrade mechanism is decided with you before deployment rather than wished for afterwards.
