How Buying Works

From browsing to fish-in-tank, here's exactly what happens at every stage.

1
Browse & Discover
Explore the marketplace without an account. Filter by species, price, pedigree, or shipping availability. Every listing shows the breeder's verified identity and care parameters.
2
Place Your Order
Found something you want? Open the app, connect your wallet (social login works too), and hit Purchase. Your payment is sent to the escrow smart contract — not to the seller.
Note: Sellers cannot access your funds until you confirm receipt. They're locked on-chain.
3
Seller Ships or Arranges Pickup
The breeder is notified and prepares your specimen. For shipped orders, they pack using insulated boxes with heat/cold packs and overnight delivery. Local orders are arranged for in-person handoff.
4
Receive & Inspect (72-Hour Window)
When your fish arrives, you have 72 hours to acclimate and inspect. If everything looks healthy, confirm receipt in the app and funds release to the seller.
If there's a problem: Open a dispute within the 72-hour window. Provide photos/video and our resolution process kicks in automatically.
5
Funds Release & Review
Once confirmed, the seller receives payment minus the 4% platform fee (a portion of which goes to aquatic conservation). You can leave a review that's permanently attached to their breeder profile. The specimen is minted to your logbook.

How Escrow Protects You

Your money never goes directly to a stranger on the internet. It sits in a transparent smart contract that both parties can verify.

Smart Contract
Holds funds securely
🐟
Breeder (Seller)
Receives after confirmation
What happens if the fish arrives dead? Full refund, automatically. The escrow releases funds back to you. No arguing with a seller. No PayPal disputes. The contract handles it.
What if I don't confirm within 72 hours? After the window expires, funds auto-release to the seller. This prevents buyers from holding funds hostage. Make sure to inspect promptly.
Can the seller take my money and not ship? No. They can't touch escrow funds until you confirm. If they never ship, you open a dispute and get refunded. The contract is publicly auditable on Base Sepolia.

Fees & Costs

We believe in transparent pricing. Buyers pay nothing extra. Sellers pay a small platform fee that funds escrow infrastructure, breeder verification, and aquatic conservation efforts.

🐟
For Sellers
4% per sale
A flat 4% platform fee is deducted when escrow releases. A portion goes directly to aquatic conservation programs — every sale helps protect the species we love.
Only charged on successful sales. No listing fees, no monthly subscription. Part of your fee funds real conservation.
🚚
Shipping
Set by Seller
Each breeder sets their own shipping rate (usually $15–$45 depending on distance and weather). Local pickup orders have no shipping cost.
Shipping fee is clearly shown before checkout.

🌊 Conservation Built In

🌿
Every Sale Funds Conservation
A percentage of every platform fee is directed to aquatic habitat preservation and species conservation programs. When you buy or sell on Aquacellum, you're directly funding the protection of freshwater ecosystems.

Frequently Asked Questions

Quick answers to the things most people ask before their first purchase.

Do I need a crypto wallet to buy? +

You can sign in with Google, Apple, or email — a wallet is created for you behind the scenes. You never need to manage seed phrases or buy crypto directly. Payments are processed in USD and converted automatically.

How do I pay? Do I need cryptocurrency? +

You can pay with a credit card via Stripe. The system handles the on-chain escrow deposit for you. If you prefer, you can also pay directly with ETH on Base. Either way, the escrow protection is identical.

What if my fish arrives stressed but alive? +

Shipping stress is normal — most fish recover within 24-48 hours after proper acclimation. The 72-hour window gives you time to assess. If the fish dies within that window, the live arrival guarantee still applies. Document everything with photos.

Can I buy from any state? Are there restrictions? +

Most freshwater species ship nationwide with no restrictions. Some states have regulations on certain species (e.g., snakeheads, certain crayfish). Breeders are responsible for knowing shipping restrictions. If a species can't ship to your state, the listing will indicate it.

What happens during extreme weather? +

Sellers can place a weather hold on your order if temperatures at origin or destination are below 20°F or above 100°F. You'll be notified and shipping resumes when conditions improve. Your escrow remains locked and protected throughout the delay.

How do I become a seller? +

Open the app, switch to Breeder mode, and complete identity verification. Once approved, you can list specimens from your logbook directly onto the marketplace. There's no listing fee — you only pay the 4% platform fee when a sale completes, and part of that goes to conservation.

Is local pickup available? +

Yes. Many breeders offer local pickup with no shipping fee. Filter the marketplace by "Local Pickup" to find breeders near you. The escrow still applies — funds release after you inspect the fish in person and confirm in the app.

What blockchain is this on? Do I need to care? +

Aquacellum runs on Base (an Ethereum L2). But you don't need to think about this at all. Gas fees are covered by us, wallet creation is automatic, and the escrow works in the background. The blockchain is the infrastructure — not the user experience.
