Leave clear onchain instructions so the people you trust can reach your crypto if you cannot.
Tradespeople log each repair with photos and a customer signature, sealed onchain as a warranty.
Try it live, freeYour USDC is locked in a smart contract, not sent to us. We can only collect it by delivering before 27 Oct 2026. If we miss it, you take it back yourself from My apps, no permission needed. We can also refund you any time. View the contract on BaseScan.
Promised delivery: 27 Oct 2026 (counted from payment).
Add-ons are not part of this payment. Once your app is delivered you can request them from My apps, and you only pay if you say yes to the quote.
Joy fixes a boiler and her customer taps to sign on her phone. A year later when the part fails, both of them can pull up the sealed job record without arguing about dates.
Job log with photo hashes, customer signature via email or wallet, warranty page, worker profile.
Reshape it entirely: new features, your flows, your brand end to end, integrations you need. We scope it with you.
Blockchain-anchored job photos exist; a tradesperson repair warranty flow is less common.
Kura and Record360 anchor inspection photos to blockchains, and WarrentChain stores warranties onchain, but none combine repair logs with customer signatures for tradespeople.
Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.
Real-world payments and apps; existing projects OK.

The complete Fix Proof app: tradespeople photograph each repair, get the customer's signature on any phone and seal the job with its warranty, so a year later it is a fact both sides can check.
Every buyer gets the same finished app. Basic branding and copy changes come through a quick form.
Your admin side: revenue, paywall editor, users, rules and the agent log.
Referral and growth mechanics, switched on when you are ready to grow.
Traders start free and upgrade per month in USDC. Firms pay for Crew, and trade associations pay for a branded edition for their members. Customers never pay to see their own job.
Association editions from $250 a month. Gas (under 1 cent per seal) and SMS (a few pence per job) can be sponsored by the owner.
Prices are yours to set. Illustrative, not a promise of income.

Custom work from $1,100: your own trades and job templates, integrations with job management or accounting tools, extra languages, or an association branded deployment. Scoped on a call.
The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.
Small tradespeople lose time and money when customers dispute what was done and when. Paper job sheets get lost, and platform reviews belong to the platform, not the worker.
Close neighbours exist: Kura and Record360 anchor inspection photos to blockchains, and WarrentChain stores warranties onchain. What is less common is one simple flow built for a solo tradesperson: photos, a customer signature that works on any phone, warranty terms, and a public work history the worker owns. The pieces are not new, the combination for this user is.

Every honest repair becomes a fact both people can check, and every tradesperson owns the proof of their craft.
The argument that never happens When a part fails, both sides open the same sealed record. Dates and terms stop being a matter of memory.
A profile that is yours Hundreds of signed jobs form a work history no lead site can delist or charge to show.
Friday record A weekly summary of jobs sealed, a streak, and warranties ending soon, which doubles as a list of people to call for a service.

Cost per use: unlocked when your app is paid in full.
Every sealed job sends the customer a copy with the worker's name and a link. Customers forward it to neighbours and family, profile links get shared in local groups, and service reminders bring the same customer back each year.

Nine routes from one vessel. Tap a port to open its chart.
Fix Proof lets a tradesperson seal each repair with photos and a customer signature, so a warranty claim a year later is a lookup, not an argument. Owning it means the trades firms that rely on it pay you, and every sealed job carries your brand into homes in your area. It is a quiet, trusted record nobody can edit, and you are the one who runs it.
You don't need to. The app ships deployed to your wallet with a setup guide. Your work is standing next to one tradesperson for a morning and helping their first customers sign.
Many do. Keep it to one tap after the job, and pitch it as fewer warranty arguments, not as crypto. Some will never switch, so start with the ones who already photograph their work.
It is evidence of what was done and when, not a legal contract by itself. Firms should keep their normal written terms and use Fix Proof as the proof behind them.
Yes. The contracts deploy from your wallet, and the brand, domain and customer list are yours. DEPLOYR takes no cut of what you charge after purchase.
Records live onchain on contracts deployed from your wallet, so a page outage does not erase anything. Setup issues are covered by the get-it-shipped promise.
Trades firms pay a monthly plan per van or technician, and trade associations pay for a branded version for members. Reaching $1M a year is a target to plan toward, not a promise. Most growth comes from associations and suppliers, not single traders.
Illustrative stages, not a forecast. Results depend on you and the market; nothing here is guaranteed.

A hackathon cockpit that plans your scope, tracks bounties, and drafts a judge-ready submission.

Tenants and landlords seal move-in photos and rent receipts so deposit disputes end fast.
Airdrop hunters prove they are one real person with one main wallet and get ranked fairly.
