Unframed

Unframed is an NFT marketplace on Starknet, built by a small team spun out of Argent with the aim of matching mainnet trading experience on an Ethereum layer 2. Starknet's account abstraction allows multi-step actions to be signed in one bundle, which Unframed uses for one-click checkout: a single confirmation completes a purchase without a separate signature and fee setup for each transaction, something mainnet marketplaces cannot offer.

It is written in Cairo 1, with market and account contracts cooperating under the same abstraction, and listings, bids and royalty settlement all happen on-chain. Collection pages place floor price, rarity and holder distribution side by side to judge whether pricing has drifted. It worked with bridge projects to bring Ethereum collections to Starknet and used first-time drops to bootstrap activity, while opening collection verification to keep impersonators out. After launch it became one of the most used marketplaces in the Starknet ecosystem, carrying most of the network's profile-picture and art volume and serving as the default venue for new collection launches.
