Zecrey aims to lower the entry barriers of blockchain by making it available for business and consumer use, while increasing privacy and security.

What is Zecrey Protocol?

Zecrey is a zk-Rollup based Layer 2 protocol featuring privacy and scalability. From the perspective of products, Zecrey provides a user-friendly wallet containing L1s and Zecrey native L2s. There are two different types of Layer 2 systems embedded into our wallet, namely, Zecrey Zero and Zecrey Legend. The first mainly focuses on privacy features and the second mainly focuses on NFT issuance and NFT marketplace.


Asset-Oriented Solution

Zecrey Protocol is a zkrollup-based solution for vertical use cases, oriented towards asset and ownership. It focuses on a fundamental need for trading that is associated with two types of assets: fungible assets like ERC20 and non-fungible assets like ERC721/ERC1155. The basic demand we will meet includes multiple scenarios derived from fungible and non-fungible assets such as:
  1. 1.
    The transfer of tokens
  2. 2.
    The swap of tokens and
  3. 3.
    The issuance and trading of NFT and so forth.
As part of our core functionality, we have ensured that Zecrey enables privacy features for fungible asset transactions, security level same as the underlying mainchain and faster transactions than any other platform. Apart from that, our solution based on zkRollup technology benefits users with:
  1. 1.
    Complete ownership of their assets.
  2. 2.
    Ultra-fast transaction confirmation speed, and
  3. 3.
    Ultra-low transaction fees.

Primitives to Applications

From the perspective of protocol layering and at the core of the architecture, Zecrey offers all the basic primitives required on the asset layer. These primitives will be used as the encapsulation provided by the bottom layer to the upper layer.
The basic primitives built with zkRollup technology will help us provide users with the ability to transfer, swap, and perform basic functions such as NFT minting, buying, and selling.
Based on the above, we will provide feature-rich and easy-to-call SDKs to the public. Speaking of SDKs, I’d like to mention that our SDKs will be unique. It will include private payment, private versions of DEX similar to Uniswap V2, and a platform for NFT issuance and transactions. For example, the SDK of NFT Issuance is based on the primitives of minting NFTs, and Zecrey L2 DEX is based on the primitives of swap.

Customized Bottom-up Architecture

Zecrey provides complete customized architecture from the bottom up. The bottom layer of this Architecture will be the infrastructure layer based on zkRollup. And the upper layer will have SDK/API to provide relevant development components. The top layer will consist of various applications including payment and NFT market products. And the outermost layer will provide products for C-end users and a multi-chain wallet with a plugin and mobile version. The customization we have implemented in this architecture gives us the capacity to design more complex interactions and customized transaction support for both fungible and non-fungible assets.


From the perspective of products, Zecrey provides a user-friendly wallet supporting L1s and Zecrey native L2s. There are two different types of Layer 2 systems embedded into our wallet, namely, Zecrey Zero and Zecrey Legend. The first mainly focuses on privacy features and the second mainly focuses on NFT issuance and NFT marketplace.
For Layer 1 functions, it mainly serves as an entry to manage assets. Now we have released the main network wallet for Layer 1s. We initially support 7 chains, mostly EVM compatible chains as well as a non-EVM chain, Near native chain.

Zecrey Zero

Zecrey Zero is a lightweight, privacy-driven, and portable payment solution, and it provides users with a simple and intuitive interface that allows users to be able to conduct private transfers and swap transactions with ease of access.
For Zecrey Zero, we enable privacy features where users can conduct private transfer and private swap transactions. The privacy feature here we mention is mainly related to transaction amount, which means the transaction amount will be concealed by protocol, and no one but yourself knows.

Zecrey Legend

Zecrey Legend is the first zkRollup L2 scaling solution on the BNB chain and NFT engine of Web3 games. It offers instant trading, massive scalability, and low gas fees for minting and trading NFTs without compromising security.
For Zecrey Legend, it could be viewed as an NFT marketplace on Layer 2, the first zkRollup based Layer 2 solution on BNB chain. As the strategic partner of Binance Labs and BNB chain, Zecrey Team created the NFT market with a consistent high-quality design and solid cryptographic scheme.
Zecrey Legend supports Mint/Transfer/Auction/Withdraw NFTs for NFT buyers and artists.
Users can operate NFTs in low gas (even zero gas) in the layer 2 network and withdraw the layer 2 NFT to the underlying layer 1 network. NFT transactions on Zecrey NFT Market are advantageous with faster speed, low even no gas fee and sound security shared with BNB chain. And royalty can be set by NFT artists to incentivize creative genius.
Zecrey Legend mainly provides the following powerful SDK components for Web3 games:
  1. 1.
    Account Management: including integration with layer 1 and layer 2 user information
  2. 2.
    Asset Management: FT-related primitive support, such as Dex, payment, etc.
  3. 3.
    NFT Operation: Including NFT query, issuance, order creation, purchase, transfer, etc. In the NFT query part, Legend is supported by a separate marketplace like Opensea, so games can gain easy access to the NFT market on the layer 2 network, and enjoy customized functions without reinventing the wheel.
  4. 4.
    Resource Storage: storage of in-game resources, including media resources, etc. Players can enjoy convenient in-game experiences including: NFT mint with 0 gas fee Millisecond level transaction confirmation Fast marketplace integration


September 2022 has been a great month for us. Zecrey celebrated its first monumental milestone. Together with BNB Chain, we open-sourced the ZKBNB Layer 2 network based on Zecrey’s underlying technology, allowing anyone and any team to build their own Layer 2 network platform in a short span. And Zecrey-Legend will also be the first end-to-end zkRollup solution on the BNB chain.
After completing the open source work of zkBNB, our next milestone will be to release the Zecrey Legend on testnet and mainnet in Q4. We are also planning to release a more complete web3 game SDK integration solution and cases for more developer teams who are interested in the game track.
