Deciding whether you need a chain at all
The honest test is whether you need users to trust an outcome without trusting you. Ownership that must survive your company shutting down, settlement between parties with no reason to trust each other, or assets people expect to trade elsewhere are real cases.
If the answer is that a database would do, we will say so. A lot of projects carry the cost and risk of a chain for a feature nobody asked for, and it makes the product slower and harder to use.
How we write contracts that will not be drained
Most losses come from a short list of known mistakes: reentrancy, unchecked external calls, bad access control, integer assumptions, and upgrade keys held by a single wallet. We write against that list, keep contracts small, and prefer boring, audited building blocks over clever original code.
We test the failure cases as hard as the happy path, including what happens when a call fails halfway, when someone calls functions out of order, and when the caller is a contract rather than a person. We also tell you plainly when a project warrants a third party audit before mainnet, because our own testing is not a substitute for one.
The product around the contract
The contract is usually the smaller half. The rest is wallet connection that does not confuse people, gas costs explained before someone signs, transactions that survive a page refresh, indexing chain events so your app can search and display them quickly, and a fallback for when a node provider goes down.
Onboarding matters most. Most people who abandon a web3 product do so at the wallet step, so we design for someone who has never used one.
Chains, fees, and not painting yourself in
Chain choice comes down to fees, where your users already are, and what liquidity or marketplaces you need to plug into. Layer twos make small transactions viable in a way that mainnet does not for consumer products.
We keep the app layer chain-aware rather than chain-married, so moving or adding a network later is a contained job. Deployment scripts, addresses, and verified sources are all handed over to you.
