Small purchases make sense.
Low network fees make everyday commerce a practical design target—not just high-value transfers.
SOLANA COMMERCE, WITH A HUMAN SIDE
Crypto checkout.
Human
confidence.
Pay with crypto. Hold value in stablecoins.
Release to the seller when the order earns it.
The buyer-protection layer connecting onchain payments to the part that matters: what happens after you click pay.

01 / THE TRUST GAPBEYOND “TRANSACTION CONFIRMED”
You bought the drop.
Not the plot twist.
Crypto can confirm a payment. It can’t tell you if the sneakers in the box are the sneakers you ordered. That last mile of trust is still missing.
LIMITED DROP / EVERYDAY TRUST
Payment confirmed.But is the pair authentic?
THE MOMENT AFTER PAYThe chain says “success.”
The chain says “success.”
Your order says “we’ll see.”
A limited-edition pair. A seller you’ve never met. An irreversible transfer. The excitement is real. So is the leap of faith.
Let the order earn the payout.
Keep the value protected while delivery, inspection and a clear dispute process do their job.

STEP 01
A checkout, with a safety net.
Start with 120 USDC on Solana. This walkthrough illustrates the product flow; it does not connect a wallet or move funds.
Direct USDC is the reference flow. Other assets require a supported conversion route.
Illustrative flow, not a live transaction. The dispute window runs for 15 days / 360 hours after verified delivery. Returns and refunds follow evidence review.
For buyers
Time to inspect. A path to resolution.
For merchants
Clear rules. Evidence-based outcomes.
For everyone
One visible record from checkout to close.
03 / WHY SOLANA BUILT AROUND REAL COMMERCE
Fast money.
Thoughtful settlement.
Solana handles the movement of value. EnsureBack connects that movement to delivery, protection and a final outcome people can understand.
Rules follow the funds.
A program-controlled token vault binds protected value to an order, its participants and permitted settlement.
Commerce brings repeat use.
Our thesis: a purchase that goes well becomes another purchase. Buyer confidence can turn wallets into customers.

04 / TRUST THAT TRAVELSCHECKOUT REVIEWS
New storefront.
Same good name.
Your gaming profile follows you.
A seller’s reviews should, too.
EnsureBack collects reviews from buyers after their purchases and brings them into the seller’s virtual POS. Wherever that seller integrates EnsureBack, shoppers see their review history right at checkout.
01
Collect after the purchase.Buyers review their shopping experience. The review belongs to the seller’s history.
02
Carry it with the POS.The same seller integrates EnsureBack on another website. Their reviews travel with them.
03
Show it before the next payment.The next buyer sees the seller’s collected reviews inside checkout, before deciding to pay.

A strong story deserves inspectable work. Here is what exists in source, what this page demonstrates, and what still needs real-world validation.

THE FOUNDER THESIS
The payment is only the beginning of the transaction. Trust is everything that happens after.
Mikail Gürbüz · Founder, EnsureBack · Computer engineering academicTHE QUESTIONS THAT MATTERClear answers.
Clear answers.
No magic tricks.
Is this an insurance product or a chargeback?+
This showcase describes a programmable hold and dispute-resolution workflow. It does not promise insurance coverage or reversal of an already-final blockchain transfer. Release and refund depend on held funds, evidence and the applicable policy.
Does every token automatically become USDC?+
No. Direct USDC on Solana is the reference flow shown here. Other supported assets would need a separately validated conversion route before entering a stablecoin hold. Availability, pricing and execution must be established per route.
Who decides whether the seller gets paid?+
The offchain policy engine uses delivery evidence and protection deadlines. If a buyer opens a dispute, an administrator reviews evidence; a defect decision may require a return. The seller has a 72-hour review window after return delivery in the target policy. The onchain program requires authorized settlement; it does not inspect physical goods.
When does the 15-day dispute window start?+
The dispute window starts after verified delivery and runs for 15 days, or 360 hours. An open dispute keeps the order on hold while evidence is reviewed. A return-related 72-hour seller review is a separate period; it does not replace the buyer’s 15-day window.
What are Checkout Reviews?+
EnsureBack collects buyer reviews after purchases and displays the seller’s review history inside the seller’s EnsureBack POS. When the same seller integrates that POS on another website, the reviews remain visible to buyers during checkout. The reviews follow the seller; they are not a score assigned to the buyer.
What is live, and what is a demonstration?+
EnsureBack has an existing Stripe-oriented product foundation. The Solana program and EnsureConnect workstreams have inspectable source modules and tests. This page’s payment flow and Checkout Reviews demo are illustrative; they do not execute payments. Production Solana readiness, audit status and live marketplace payouts are not asserted.
