– NFT Marketplace for Bitcoin Secured Stacks NFTs

This comprehensive Review will completely guide you through how NFT marketplace works, its features, etc:

What is

Non-fungible tokens, which are unique digital assets on the blockchain, which aren’t interchangeable with one another, have been very popular on Ethereum and second and third-generation blockchains.

Ethereum alone carries 76% of all NFTs with over 7,000 daily mints because it supports smart contracts. It originates from the NFT token standard ERC-721, and has the highest number of decentralized apps, in addition to its popularity after Bitcoin.

However, Bitcoin still commands nearly 50% of the entire crypto market share, is the most traded and held crypto, and remains the most popular cryptocurrency. Despite this, NFTs on Bitcoin have been nonexistent. It is this gap that the NFT marketplace seeks to fill. Gamma is based on Stacks, a programming layer that introduced smart contracts on the Bitcoin blockchain. Review NFT Marketplace Review allows creators, builders, and artists to create, list, and display NFTs and related smart contracts on the Bitcoin blockchain; collectors to collect, store, and list their NFTs on the Bitcoin blockchain; buyers and sellers to list and sell their Bitcoin NFTs; and investors to invest in Bitcoin NFTs.

These Bitcoin NFTs and smart contracts built or based on can be transferred to and from other NFT marketplaces and blockchains. marketplace currently supports more smart contracts than any other dApp on the Bitcoin network. It currently hosts over a thousand NFT collections, 80% of which have been created using the No-code creator tools.

How NFT Marketplace Works

Gamma makes Ordinal inscriptions on the Bitcoin network as easy as ABC.

makes inscriptions

In February 2023, released the No-code Creator platform for Ordinals, Bitcoin native NFTs. Ordinals were made possible through the Bitcoin Taproot upgrade, allowing users to inscribe individual satoshis with arbitrary content to create unique artifacts, which can be stored in Bitcoin wallets and transferred using Bitcoin transactions.

The process of creating these inscriptions is ordinarily complex and technical. removes the complexity with its creator platform. You make the inscriptions by simply creating a text or uploading files and specifying other things such as the address and making the required payment in BTC.

With, you can choose to create NFTs and/or collections and then trade them on the same platform or promote them on third-party NFT marketplaces.

  • To mint, trade, and store NFTs, you need to connect an Ethereum or Stack wallet. You obviously need to keep the wallet’s private keys and seed phrases somewhere safe and never share them with anyone. You then send Bitcoin or STX tokens to the wallet. These will be spent as transaction fees when minting, buying, and selling NFTs.

Features of the Marketplace

#1) Native Bitcoin Payments: allows users to trade Ordinals using Bitcoin as a primary method of payment for sellers and buyers. Users can trade, buy and sell native Bitcoin NFTs using native Bitcoin transactions.

Gamma started to support the minting and secondary selling of Stacks NFTs using Bitcoin (via the Bitcoin Lightning network) as the native currency on the blockchain through a partnership with

#2) Stacks Token (STX): Stacks has a native token that serves as a gas token for smart contract interactions. It is also spent when minting and used as a payment method for the secondary trading of smart contracts.

#3) Creator Portal: creator portal has a host of creative tools that allow users to create NFTs from scratch and deploy smart contracts on Stacks mainnet, no-code needed.

First, the creator launchpad allows anyone to create an NFT from scratch and in minutes, without any coding knowledge or skill. You only need to define and describe your NFT and optionally upload files (CSV format files) containing custom metadata for the NFT. Data must thus be inputted or entered into the file in the correct format to be readable.

Metadata, though optional, can help set apart your NFTs, improve their accessibility, determine rarity, allow filtering and sorting, and add descriptions that are not accessible on images such as sounds, etc.

New features on the Creator Self Service Portal allow users to launch smart contracts for custom NFT collections. They can thus host their websites, minting page, or marketplace. Users can request a minting page at A community that has a self-service collection can mint and trade their NFTs from the platform. also partners with The Mintery NFT Collective to provide creators with funding and support for creating NFTs. This is recommended for those who want to create highly specialized NFTs or those who need hands-on mentor assistance and/or technical resources.

#4) Individual NFTs and/or Collections: Gamma supports three types of collections, and each collection has to be approved before it goes live. The marketplace charges 10% from the initial sale for using No-code tooling, and 2% on secondary sales on the marketplace.


Creators and artists can create different types of NFT collections. These include Continuous, Public mint, and Editions. A continuous type allows you to add more NFTs (say of the same theme, concept, and technique) to the collection, at a later date.

Each NFT will need to be listed individually for sale in the marketplace. For this type, the NFTs are minted directly to the creator’s address, collectors view the NFTs before they are listed for sale, and auctions are first requested and approved.

Public Mint, a traditional collection type, involves creators creating all NFTs at once and buyers minting them into existence.

The buyer will mint from a public page without seeing what NFT they will receive, collection size cannot be increased after deployment (but can be permanently reduced), and the media is revealed when the buyer receives the NFT on their wallet or after the reveal is initiated by the creator.

The third type of collection — Editions is mostly used for projects such as tickets to events, proof of attendance NFTs, software licenses, access to a platform, etc.

Like the public mint, the minting phase also allows creators to use a mint pass or airdrop feature. The media for all NFTs in an Editions collection is identical, and the size of the collection cannot be increased after deployment.

#5) Ability to connect to an external NFT wallet: Like many other NFT marketplaces, does not have a hosted or custodial wallet.

The Gamma NFT marketplace allows users to store their NFTs on a linked external Stacks wallet which provides access to Stacks apps.

There are two Stacks compatible wallets — the Hiro wallet, which works as a Chrome browser extension wallet, and the Xverse wallet, which is a Bitcoin blockchain-based mobile (iOS and Android) browser and Chrome extension. The NFT marketplace also supports connecting Ethereum wallets.

Both the Hiro and Xverse wallets are used to store, send, receive, and manage STX and other (NFT and non-NFT) tokens.

Some of the Ethereum wallets that you can connect to and use to view and manage your NFTs on include, Coinbase, WalletConnect, and Rainbow.

#6) Customizable user profiles: Create a profile, see other people’s profiles and blockchain activity, and follow them.

customisable user profiles

An account profile is created after connecting a wallet, and you can add other details such as a bio, your website, and Twitter handle, as well as link multiple accounts (for example, link your Ethereum wallet to your Stacks wallet in order to see all your NFTs in one place).

#7) Auctions: launched with buy-it-now NFTs or fixed-sale NFTs. However, the platform later introduced an auction feature allowing people to auction and bid on NFTs. This is helpful for those sellers who do not know the exact value of their NFTs and those buyers that want to bid on rare NFTs.

Related features that are planned for launch in the NFT marketplace include private sales and a bundle of items.

#8) Sort-and-filter Menu: allows users to search for NFTs from the marketplace using varied search criteria. Such criteria include NFT pricing, rarity, and other attributes. The all-in-one search bar also allows users to search NFTs with specific collections and user profiles.

#9) On-chain Data: This data avails users with transaction histories which are recorded at the individual NFT level. Using such metrics, NFT traders, collectors, investors, and creators can make informed decisions relating to creating, buying, selling, collecting, and investing in NFTs.

#10) API: The marketplace API allows users to connect it to third-party apps.

#11) Bitcoin Naming System Domain names: marketplace for NFTs allows users to send, receive, buy, and sell BNS names.

BNS names are listed for sale at

BNS for sale - Review

A BNS name is a .btc URL name associated with an alphanumeric wallet address that can be used (when sending/receiving NFTs/crypto, or for identity as a profile, collection website/page, or as the homepage on the internet, promotional purposes on social media) instead of the long and hard-to-remember alphanumeric wallet address.

It’s easier to remember a handle than an ordinary wallet address.

A custom BNS name can be registered on the at the cost of 2 STX for 5 years after which it is to expire and needs to be renewed. Users can also buy them from the Gamma marketplace by searching the BNS Names collection on the marketplace search bar and filtering through the categories to arrive at the name they need to buy.

They can also send a BNS Name to a different wallet address after buying it. Users can also sell BNS Names associated with their wallet addresses by listing them on the marketplace.

Only one BNS Name is associated with one wallet address at a time. The NFT must be held on a smart contract while listed for sale.

#12) Social Platform: The social platform brings together creators, artists, and investors in NFTs. The platform does not require users to set up accounts or profiles. They can, instead, follow each other and engage using web 3 identities. For instance, they can follow each other based on their public blockchain data, whether they have used Gamma or not.

How to Create/Author NFTs on NFT Marketplace allows users to mint a single NFT or a collection. It allows users to create them on the Bitcoin blockchain, all with complete control and ownership (the user retains private keys to their NFTs).

The marketplace keeps 10% on the first sale only in the case the creator used the no-code tool — no ongoing fees or restrictions afterward. A user can launch an NFT in less than 5 minutes for under $1. Creators define their royalties on the secondary market.

Here you configure your website with custom minting pages, seek listings on other marketplaces, or request Gamma minting page for the collection (which can be automatic).

Step #5: Promote the collection. It is advisable to have a community behind your NFT collection although there are many other ways of promoting the collection.

How to Buy and Sell NFTs on the Marketplace

Gamma supports the initial sale or mint of collections and secondary marketplace sales. Both incur the NFT’s author royalties (as defined by the author) and a marketplace commission. Both are shown when you list an NFT for sale.
