Coin or piece: why the address matters

A chain’s own coin and a piece from a contract can sit side by side in a wallet, but they come from different places. That difference is why copycat collections exist, and knowing it is the simplest protection there is.

Coins come with the chain

A native coin is part of a chain, created by the chain’s own rules. ETH on Base is that kind of coin. You cannot deploy a fake ETH on Base, because the coin is part of how Base works.

Pieces and many coins come from contracts

A smart contract can issue what a wallet holds. The contract keeps a list of who holds what and the rules for moving it. USDC is issued by a contract. So is every NFT, including every piece on KURV.

Because anyone can deploy a contract, anyone can make a coin, or a whole NFT collection, with any name and any images. Two collections can share the same title, the same art and the same description. The only thing that cannot be copied is the contract address.

What a contract address is

On Base, addresses start with 0x followed by 40 letters and numbers. Every collection launched on KURV has its own contract, at its own address. A copy launched somewhere else has a different address, even if everything else looks identical.

Interchangeable coins and unique pieces

• Interchangeable coins are the same unit for unit: one USDC is the same as another. On Base these usually follow a standard called ERC-20.
• Pieces (NFTs) are unique: each one has its own ID. These usually follow ERC-721 or ERC-1155.

Standards are why wallets and marketplaces can display assets they have never seen before.

How copycat collections work

1. A collection gets attention.
2. Someone downloads its images and metadata.
3. They deploy a new contract with the same name, often somewhere other than the original platform.
4. They post links in replies and DMs, often with a lower price or a “free claim”.
5. Buyers end up with pieces from the copy’s contract, which have nothing to do with the original.

Checking you are on the real collection, step by step

1. Start from testnet.kurv.fun, typed in yourself or from a bookmark. The public site at kurv.fun is the landing page. The app, where you mint, is testnet.kurv.fun.
2. Find the collection through Explore or the creator’s own link.
3. Check the creator shown on the collection page.
4. If someone sends a link, compare it with what you found yourself rather than trusting it.
5. For brought-over collections, check the contract address against what the creator publishes.

A concrete example

A cat collection launches on KURV and does well. A day later, a post appears: “Grumpy Whisker Club free claim, today only”, linking to a different site. The images are the same. The page asks you to sign. The contract address does not match the one on the collection’s KURV page. It is a copy, and possibly a drainer.

Coins, pieces and KURV

• KURV collections are priced in one coin per collection. On Base that is USDC by default, or another coin on Base. On Solana it is SOL, or another Solana coin.
• KURV itself has no coin of its own. If you see a “KURV coin” anywhere, it is not from KURV.

Brought-over collections

KURV also lets creators bring a collection that is already on Base. Those collections keep their own contract (and trade at their own royalty, with no Vault). For them, the contract address is especially important: the creator publishes it, and the KURV page should show the same one. If they do not match, stop.

Why names are cheap and addresses are not

A name is a label a creator types into a contract. Typing “Grumpy Whisker Club” costs nothing and proves nothing. An address is generated when the contract is deployed and cannot be chosen freely, so two contracts cannot share one. That is why every safety guide comes back to addresses: they are the only part of a collection a copycat cannot fake.

A habit worth building

Keep a short list (a note on your phone is fine) of the collections you care about and the official links to them, taken from the creators’ own pages. When something new pops up claiming to be one of them, compare it with your list.

Common mistakes

• Searching by name and minting the first result.
• Trusting links in replies or DMs.
• Assuming the same art means the same collection.
• Thinking every app has its own coin. KURV does not.
• Checking only the first and last characters of an address. Scammers generate lookalikes.

FAQ

Is USDC a chain’s own coin? No. It is issued by a contract. On KURV we still call it a coin, because it is what you pay with.

Are KURV pieces NFTs? Yes. Each one has its own ID, issued by the collection’s contract.

Why can copies not be stopped? Anyone can deploy a contract. What you can control is where you mint.

Does KURV have a coin of its own? No.
