Blockchain and Web3

What this category is

Blockchain work covers everything that has to run on a public chain and everything that has to talk to one — Solidity contracts for tokens, escrow, staking and vesting; independent security review before mainnet; token launches; NFT collections and the mint sites that sell them; multi-contract applications and DeFi protocols; crypto checkout inside an existing store or SaaS; and automated trading systems.

Who buys it is more varied than the category's reputation suggests. Web3 startups and protocol teams commissioning the product itself. Crypto founders preparing a launch. Creators and brands issuing membership passes, tickets or loyalty items that live in a holder's wallet rather than in a database. E-commerce and SaaS businesses adding stablecoin payment because their customers are in markets where cards work badly, or because chargebacks are costing them. Traders and funds who want their own method executed consistently instead of by hand at three in the morning.

What separates this category from everything else we do is that mistakes here are permanent. A bug in a website is a bad evening. A bug in a deployed contract holding other people's money cannot be patched, the funds do not come back, and the incident stays attached to the project's name. That single fact shapes how the work runs — written specifications down to the function, tests longer than the code they test, testnet rehearsals you drive yourself, independent review before real value arrives, and ownership handed to your multisig on deployment day.

    Price and date

    A fixed scope, a number and a delivery date, agreed before anyone starts.

    Same week

  3. 03

    Final day

See where the site stands before you brief anyone.

Before scoping Blockchain & Web3 work, it helps to know what the site is doing today. The audit reports what it checked, what it found, and — the part most tools leave out — what it could not check, and why.

Questions people ask before they commit.

Do we actually need a blockchain for this?
Frequently not, and we would rather establish that in the first conversation than six months in. A chain write executes on every node in the network and is kept permanently, which is exactly why it is slower and costs more per write than an ordinary database. What you are buying with that cost is the removal of a trusted owner. If your system already has an authority everyone accepts, signed records with a public verification page usually deliver the same assurance faster, privately and for less. We will price both routes and tell you which one we would choose.
Can a contract be fixed after it goes live?
Not by editing it. A deployed contract is immutable, so a fix means deploying a new one at a new address and migrating state and users across, which is a project in itself. This is why upgradeability, pause design and admin powers are all settled in writing during specification, and why we treat testnet acceptance as a milestone you sign off rather than a formality.
Will you hold our keys, our tokens or our customers' funds?
No, on all three. Ownership of anything we deploy transfers to a multisig you control, exchange API keys are created by you with withdrawal permission disabled, and crypto checkout runs through a hosted processor that takes custody. Your project funds never pass through our wallets, and we do not accept payment in a project's own token.
Who pays the network gas fees?
You do, from your own wallet, and it is written into every scope. Fees are set by network congestion rather than by us, so we give estimates and never a fixed figure — the same deployment costs whatever the network is charging when it runs, which is not the same on a busy mainnet as on a quiet one or on an L2.
How do payments work on a project like this?
In milestones tied to visible progress rather than a deposit and a final invoice — typically scope approval, a working system demonstrated on testnet, security findings resolved, and mainnet deployment with handover. Launch-day support is always a separate line item with defined hours, and everything before mainnet deployment is settled before that deployment happens.
Which chain will you build on?
Whichever one the decision actually points to, argued in writing during scoping. It turns on where your users already are, what a transaction needs to cost them, how much security the value at stake justifies, and which tooling and marketplaces you need to work with. It is one of the few decisions here that is genuinely difficult to reverse later, so it does not get made casually.

Work that usually comes with it.
