Are royalties guaranteed?

Not everywhere. ERC-2981 publishes royalty information, but each marketplace decides whether to pay it. Your own marketplace can enforce it; others may not.

Where is the artwork stored?

Usually on IPFS or Arweave, referenced from the token, so the item does not depend on one company's server staying online.

Can buyers pay by card?

Yes, through an NFT checkout provider, with the item delivered to a smart wallet created for the buyer.

Which chain should we use?

Low-fee networks such as Ethereum layer-2s suit most marketplaces, because minting and trading many items on Ethereum mainnet is expensive.

Web3 · Service NFT marketplace development

NFT marketplaces and minting platforms: ERC-721 and ERC-1155 contracts, listings and auctions, royalties, metadata storage and fiat checkout.

In short

An NFT marketplace lets people create, buy, sell and transfer non-fungible tokens — unique digital items such as art, tickets, memberships, in-game items or certificates. Under the surface it is a set of token contracts, a trading contract for listings and auctions, storage for the item data, and an indexer so the interface knows who owns what.

When you need it

Signs this is the right service

You are launching collectibles, tickets, memberships or in-game items.
Your community or brand needs its own marketplace instead of a general one.
Buyers should be able to pay by card and sign in without a crypto wallet.
An existing marketplace needs new sale formats, chains or better performance.

What's included

What you get

Token contracts

ERC-721 for unique items and ERC-1155 for editions, with lazy minting so creators pay nothing until a sale.

Trading

Fixed-price listings, offers and auctions, with signed off-chain orders settled on-chain.

Royalties

ERC-2981 royalty information on every token — noting that not every marketplace enforces it.

Metadata and media

Images and metadata stored on IPFS or Arweave so items do not disappear with a server.

Mainstream checkout

Card payments, email or passkey sign-in and sponsored gas, so buyers do not need crypto first.
