The demand for multi-chain or cross-chain technology in the market has become evident. According to Dune Analytics, the Total Value Locked (TVL) of cross-chain bridges has increased by 48.8% compared to the previous month, reaching a staggering $22.48 billion and continuing to grow. This trend is unstoppable, and the DeFi market is officially embracing the concept of "multi-chain coexistence."

As the market presents new opportunities and investors seek diverse choices, it is no longer feasible to confine interactions to a single public chain or a few specific decentralized DApps as was done in the past. Users now desire the ability to transact their assets across different blockchains without relying on third parties. In this new era of DeFi, a cross-chain solution with high efficiency and security, such as the Sisu network, may emerge as the answer.

Sisu network is an ambitious blockchain project focused on solving cross-chain communication challenges. Sisu is actively building critical interoperability infrastructure for a cross-chain future, which includes distributed key signing, support for private transactions, and the development of an API Hub.

Distributed key signing holds the key to a decentralized network. Many cross-chain communication solutions rely on a single owner of the gateway smart contract. However, this approach has its disadvantages due to the presence of a single point of failure. If the key is compromised or the key holder acts maliciously, all the assets locked in various chains could be at risk. This is precisely why Sisu network implements distributed key signing, providing enhanced security and decentralized solutions.

Addressing the issue of private cross-chain transactions is another focus for Sisu. Currently, crypto transactions, including token swaps, lack privacy. However, Sisu network supports private cross-chain transactions and even works with chains that have public data, such as BTC and ETH.

In order to enhance the experiences of both users and developers, Sisu is developing an API Hub that allows developers to interact with cross-chain contracts without the need to learn a new language. This includes the ability to send messages and integrate smart contracts across different chains. By building an API Hub, Sisu empowers developers to save time by eliminating the need to learn multiple blockchain languages, enabling them to focus on their core product. Furthermore, contracts deployed on one chain can now be utilized by users on different chains, expanding the user base and potential reach.

Designing a universal API hub is no easy task, given the different APIs and languages used by various chains. However, this is the goal that the Sisu team is diligently striving to achieve, as it would unlock new possibilities and strategies when deploying smart contracts. The team has a planned roadmap with different milestones and goals, and any future changes will be updated on the Sisu website.

The roadmap for Sisu encompasses several stages:

1. Cross Chain Token Swap: This stage involves testing the swapping of non-native tokens across different chains, including common tokens like ERC20 and NFT. The Sisu development team will collaborate with other crypto teams interested in building decentralized exchanges (DEX) to release the testnet version.

2. Native Coin Swapping: This stage allows users to perform native coin/token swapping instead of relying on wrapped tokens. Liquidity providers can stake their contributions on the testnet and receive Sisu's tokens as rewards.

3. API Hub for Cross Chain Contracts: Sisu deploys a contract gateway on different chains, enabling developers to interact with remote contracts through the gateway using familiar programming languages, rather than having to learn multiple blockchain languages. At this stage, the source code and testnet are also made available to the public.

4. Private Transaction: Recognizing the importance of transaction privacy to many users, Sisu offers the option to shield transactions through the Fang deployment, albeit with a minor additional cost.

5. Mainnet
