What is Gamma?
Gamma is an open marketplace and creation portal for digital collectibles secured by the Bitcoin blockchain. The platform allows users to explore, trade, and mint Bitcoin Ordinals inscriptions alongside NFTs built on Stacks, a Bitcoin smart contract layer.
Team and background
Gamma was founded in 2021 by Jamil Dhanani, a former Apple engineer and Stanford graduate student, along with co-founder Nick Sainato. Originally launched under the name STXNFT in September 2021, the venture rebranded to Gamma in April 2022 to broaden its scope across the Bitcoin ecosystem. The company is headquartered in the United States with a team size of 11 to 50 employees.
Marketplace mechanics and tooling
The platform operates non-custodially, meaning users connect supported Web3 wallets to trade inscriptions and tokens directly without surrendering private keys. Gamma provides a no-code launchpad that lets creators deploy collections and mint smart contracts without writing code. In addition to marketplace listings, Gamma provides API infrastructure that powers third-party wallets and decentralized applications across the Bitcoin ecosystem.
Trading, creator fees, and royalties
Gamma supports opt-in creator royalties on Bitcoin Ordinals, giving artists the ability to receive secondary sale revenue when supported by wallet configurations. Transactions settle on Bitcoin L1 or the Stacks layer, requiring users to pay corresponding network miner fees as applicable.
Track record and platform risks
By April 2022, creators had used Gamma's no-code portal to deploy nearly 500 collections. By January 2023, the platform supported over 1,000 Stacks NFT collections, with nearly 80% deployed through Gamma's no-code launchpad. Gamma subsequently integrated Bitcoin Ordinals following the protocol's release in January 2023. Users face risks common to Bitcoin-native assets, including volatile network transaction fees, illiquid secondary markets for niche collections, and the risk of counterfeit listings or unverified collection replicas.

Our review
3.7/5
Good
Gamma is a dedicated portal for minting and trading Bitcoin Ordinals and Stacks NFTs, but its focus leaves out collectors trading on major EVM or Solana networks.
Gamma started in September 2021 as STXNFT before rebranding to Gamma.io in April 2022. Founded by former Apple engineer Jamil Dhanani and Nick Sainato, the platform targets Bitcoin-native digital artifacts. It operates as both a secondary trading marketplace and an inscription deployment suite, supporting raw Bitcoin Ordinals along with collections on the Stacks layer.
Gamma's creator infrastructure includes a no-code launchpad. Gamma's no-code launchpad allows artists to deploy NFT smart contracts and inscription collections without writing technical scripts. By January 2023, Gamma hosted over 1,000 Stacks NFT collections, with nearly 80% deployed through its native portal. For Bitcoin inscriptions, creator royalties function on an opt-in basis, giving buyers and sellers discretion over royalty payments at checkout.
Unlike multi-chain aggregators, trading is tied directly to network-level settlements, which exposes users to fluctuating Bitcoin L1 transaction fees and slower block confirmation times during periods of network congestion.
Gamma suits creators and collectors dedicated to Bitcoin Ordinals and Stacks who want code-free minting tools and native wallet connectivity.
