# X Protocol Whitepaper

X Protocol is built with intent-based, zero-knowledge technology and Ethereum Acceleration Engine, aiming to reduce the cost of cross-chain transfers, improve cross-chain efficiency, and achieve decentralization and security guarantees.

In this article, there are two main challenges in cross-chain protocols and applications in the market: cross-chain assets and cross-chain protocols.

The problem with cross-chain assets includes the distortion of supply-demand market due to fixed fee structure and the impact of prolonged staked assets locked within the protocol. The aftermath of the problem has led to high data transmission costs incurred during cross-chain, obvious hacking opportunities of MEV attacks and the security issues with current protocols in the market.

To address these issues, we introduce an intent-centric approach. Firstly, we establish a free market pricing ecosystem by having Solvers provide optimal rates on the target chain, enabling users and cross-chain market makers to participate flexibly in the circulation of cross-chain assets. Secondly, by bringing intent-based on-chain and having Solvers provide specific Calldata, we effectively reduce the cost of cross-chain transactions and improve protocol efficiency. Additionally, the design of intent-based cross-chain protocols avoids MEV attacks and underlying protocol security verification issues, enhancing user transaction privacy and security.

By introducing the restaking mechanism, we also address the security verification issues of underlying protocols, reducing the presence of trust issues. This comprehensive solution lays the solid foundation for a more efficient, secure, and user-friendly cross-chain ecosystem.
