Chromia has officially teamed up with TAC, a purpose-built Layer-1 network aimed at resolving Ethereum Virtual Machine (EVM) compatibility with The Open Network (TON). This partnership will establish an infrastructure for Telegram Mini Apps (TMAs) to enhance their blockchain capabilities using TAC bridging technology and Chromia’s data decentralization layers.
📢We are excited to announce a NEW integration and partnership with @TacBuild! 🥳
TAC is a purpose-built Layer-1 network designed to bridge the gap between EVM and The Open Network.

This collaboration will enable developers utilizing TAC to implement EVM Johnson-based smart contracts in Telegram’s ecosystem. These contracts operate within the TON architecture, avoiding the limitations often faced by EVM-based dApps on Telegram. Chromia goes a step further by enabling applications to store their logic, user activity, and metadata on Chromia subchains, facilitating decentralization and verification of their app backends.
Enhanced Functionality for Telegram Mini Apps
Telegram Mini Apps have the potential to offer Web3 experiences to users. However, the lack of support for Ethereum-based applications on Telegram has been a hindrance. TAC acts as a translation layer, enabling compatibility between Ethereum-based protocols and the TON ecosystem.
Chromia partners with TAC to enhance Mini Apps, allowing for storage and execution of logic. Many TMAs currently rely on centralized cloud solutions, compromising transparency and trust. Chromia enables developers to transition these elements to a decentralized context, providing users with a secure and transparent experience.
Real-World Use Case: XOOB Launches with TAC and Chromia
XOOB is the first Telegram Mini App leveraging the ChromiaTAC stack. The app offers a gamified PvP and play-to-earn service, with interactions facilitated through $USDT deposits on the TON network. These deposits flow through TAC to DeFi protocols like Morpho and Euler, generating yield shared by players and developers.
Chromia subchains store all gameplay data and financial flows, offering full visibility into transactions and user interactions. This case demonstrates how decentralized systems can seamlessly integrate with platforms like Telegram. XOOB showcases the scalability and user-friendliness achievable through this collaboration, paving the way for trustless Web3 applications.
