Zecrey Protocol

A turn-key, Layer 2 privacy solution for cross-chain transactions and asset management based on Zero-knowledge (zk) Roll-Ups. With Zecrey’s L2 protocol you can easily manage, swap and bridge assets across multiple chains, all while knowing your transactions are private and protected from malicious arbitrageurs.

Zecrey is a general and scalable cross-chain privacy protocol based on zk-rollup. Zecrey protocol is based on account model, and it adopts Sigma protocol as privacy algorithm to generate privacy proofs, which shows high efficiency.

By connecting to various blockchains and layer 2 protocols through Zecrey wallet, it solves two major problems of privacy and isolation in multi-chain ecosystem pattern. Zecrey private cross-chain solution has two core functionalities: private cross-chain bridge and private cross-chain swap.

You have at your finger tips the ability to view, manage and aggregate all your digital assets across various blockchains with Zecrey's wallet. Gone are the days where you need to go through different websites and wallets to see all of your digital assets.

• • •

Not just a wallet. With Zecrey you can transfer, swap, stake, and much more across different blockchains with a high level of privacy and transaction speed thanks to a layer-2 architecture based on zk-rollup.

Supporting both Layer 1 & 2 Networks, users taking advantage of Zecrey's robust ecosystem will have all of their bases covered. Managing & aggregating multi-chain assets, NFTs, Blockchain games, DEX/OTC services, and Payment solutions are just a few clicks away.

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

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.

Privacy Enabled with One Simple Click

Transaction details are significant information for all traders and are not supposed to be exposed.

It only needs one click to conduct transactions with privacy preserved and get stable protection.

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. The transfer of tokens



2. The swap of tokens and



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 underlying mainchain and faster transactions than any other platform. Apart from that, our solution based on zkRollup technology benefits users with:

Fast and Stable Cross-Chain Transactions

Zecrey bridges various blockchain networks to enable multi-chain assets management and

transactions under privacy protection with high speed and stability.

One giant leap is cross-chain swap. Traders can make swaps simply in Zecrey L2.

1. Complete ownership of their assets.



2. Ultra-fast transaction confirmation speed, and



3. Ultra-low transaction fees.




Build a Real Private Crypto World

Most privacy protocols that support private transactions have inadequacy in programmability.

It is difficult and expensive for developers to achieve privacy protection for digital asset.

Zecrey team aims to provide a novel solution to guarantee privacy security.

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.

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.
