### TON Blockchain & Multi-Chain Ecosystem Deployment

In 2023, we chose TON as our platform due to its exclusive strategic partnership with Telegram, which boasts 900 million monthly active users. This partnership provided multiple straightforward integration entry points, including vertical wallets, facilitating seamless interaction between the two platforms. Our decision to build on TON was driven by the platform's scalability and rapid community expansion, aligning perfectly with our vision of onboarding a substantial number of Web2 users into Web3.

We are dedicated to enhancing the TON ecosystem by bridging the gap between Web2 and Web3 users. Recognizing that the TON ecosystem lacked sufficient Web3 project development teams and attention from Web3 native users, we saw an opportunity to leverage Catizen’s strong community cohesion and user-friendly approach. Catizen is not only poised to attract more Web2 users to the TON ecosystem but also to act as a conduit connecting other Web3 ecosystems to TON. This commitment led us to partner with Mantle Network for a multi-chain deployment strategy, further solidifying our role in the growth and improvement of the TON ecosystem. Catizen is also considering to apply the success of operation on to other blockchains ecosystem.&#x20;
