A new NFT marketplace that allows users to bid on NFTs anonymously has landed on zkSync Era, Polygon PoS, and Ethereum.
Blockframe is designing an NFT platform that innovates proprietary features and wants to make sure creators get priority. It was launched on Thursday.
In an interview with Blockworks, Mohamed El Yahawy, the president and CEO of Blockframe, said that the existing barriers to entry into crypto are insurmountable.
“It is very difficult for people to figure out how to get a MetaMask wallet, and once you have a MetaMask wallet, what are all these currencies and how can I do swaps,” said El Yahawy.
To solve this, El Yahawy explains that Blockframe, supported by Matter Labs, will simplify this process for its users.
“At Blockframe, we implemented single sign-on, which means users can log in with Google, Discord and Twitter, and we automatically create a wallet for them,” he said.
Once a wallet is created, users can use the same interface to launch, send and exchange cryptocurrencies. Users’ private keys are not stored or accessed by Blockframe, notes El Yahawy.
Fair price discovery
To ensure that NFT prices on Blockframe remain reliable, the team is introducing sealed bid auctions.
Instead of relying on oracles to determine NFT prices, multiple bidders can anonymously place collateralized bids to determine the value of a particular digital collectible. It is powered by Zero Knowledge (ZK) technology.
Using zkTrees, designed by Polymer Labs, the team has created “Bulk Semaphore,” a protocol designed to form market consensus on the price of an NFT through mass unidentified membership and signaling.
4/ Despite their advantages, the implementation of a sealed bid auction on the #blockchain has been impossible due to prohibitive gas costs – until now using ZK technology.

Using this protocol, an unlimited number of participants can bid on auctions at a consistent cost. El Yahawy said the tool could also be used for anonymous voting in DAOs.
“Our partnership with Matter Labs was very strategic because of their scaling and contributions to creating the Block Semaphore protocol,” said El Yahawy.
Simplifying NFTs for makers
Creators who want to launch their own NFT collections can do so directly through the Blockframe user interface (UI).
That process relies on an image editor and combiner, which can be accessed directly from the Blockframe frontend. Creators can also create editable ERC-6551 NFTs – or a smart wallet NFT that can interact with various dapps on Ethereum. These NFTs can be bulk minted to save gas.
Blockframe is also introducing a royalty protocol, which allows creators to manage royalty revenue directly.
“The idea is that creators can come here and claim royalties for their collection, thereby giving symbolic value to the collection,” said El Yahawy.
Creators can create royalty contracts for their own NFT collections, which will later represent all future cash flows. Once a royalty token is created, they can set parameters for royalty income.

At launch, NFTs with no claimed royalties will have a 0% royalty rate. The exception: the top 200 collections, which impose automatic royalty contracts.
Once prices for NFTs are standardized, Blockframe plans to ensure that royalties are applied to new collections across multiple marketplaces — an issue that has yet to be resolved.
