A New Chapter for TON DeFi: TAC Mainnet is Officially Live!

TAC mainnet enables direct access to EVM based DeFi protocols through Telegram, launching with pre-committed liquidity, bluechip DeFi primitives and production-ready infrastructure.
‍

TAC mainnet is now operational. As of July 15th, over one billion Telegram users can access their favourite DeFi protocols through simple interactions in their messaging app. No new wallets to download and configure, no technical knowledge required.

Major DeFi protocols including Curve Finance, Zerolend, Euler, and Morpho are live on the network, backed by pre-committed liquidity from the Summoning Campaign that topped at over $800 million ranging across multiple asset classes (BTC, ETH and stable based). This represents the first production infrastructure enabling sophisticated finance through mainstream messaging platforms.

Finance as Simple as Texting

The same sophisticated protocols that institutional traders use to generate billions in returns are now accessible through simple taps in Telegram:
‍

• Instant swaps: Trade tokens faster than sending a photo
• Quick loans: Access credit without paperwork or banks
• Automated strategies: Let proven protocols grow your wealth

The same institutional-grade tools that generate billions in returns are now available to a teacher in Lagos, a student in Mumbai, or a small business owner in São Paulo. For the first time in history, your ZIP code or bank account size doesn't determine your access to advanced finance, all you need is Telegram. 

Technical Architecture and Cross-Chain Innovation

TAC operates as a complete Layer 1 blockchain built on CosmosEVM vanilla, compatible to Cancun EVM fork and secured by dPoS ($TAC token). The network launches day 1 with a decentralized validation infrastructure from established operators including P2P, ChorusOne, Kiln, Kintsughi, ValidationCloud, Nodestake and Polkachu. Additional security will be provided through Babylon Bitcoin staking integration (BSN), leveraging Bitcoin's economic security for consensus validation, once the service is live.

The core innovation lies in the TON Adapter system; a novel cross-chain framework that seamlessly connects TON and TAC. 

Unlike traditional bridge architectures that rely on liquidity pools or networks of related optimization assumptions, TAC's approach uses an authoritative distributed sequencer consensus with a lock&mint mechanism that is typical of the canonical bridges for Ethereum L2s. This eliminates the high bridging fees present with intent-based bridges and the slippage introduced by liquidity bridges, enabling the extremely cheap movement of an uncapped amount of tokens between TAC and TON while maintaining the performance characteristics required for mainstream adoption.

‍Production DeFi Infrastructure

TAC brings together battle-tested protocols across key DeFi categories. Curve Finance serves as the primary DEX and liquidity layer for trading across all major pairs. The lending ecosystem features Morpho for lending optimization, Euler for permissionless lending markets, and ZeroLend for lending markets and carry trades enabling yield leveraging. Vault technologies including Veda, Lagoon, Cian, and IPOR Fusion provide automated yield strategies for users seeking simplified access to DeFi returns.

The ecosystem launches with significant liquidity backing from bluechip assets bridged during the Summoning Campaign, including partnerships with Lombard, BitFi, and Kelp.

TAC provides comprehensive developer tooling including Safe for multi-signature wallets, Tenderly for smart contract debugging, RedStone, eOracle, and Stork for price feeds, cross-chain bridge infrastructure like LayerZero, Dune Analytics for on-chain data, Goldsky for blockchain indexing and a lot more.

The network operates with institutional-grade security through comprehensive audits by Halborn covering the EVM layer and Trail of Bits reviewing the TON Adapter system, plus Quantstamp audits for proxy applications. Real-time protection comes from 24/7 monitoring by Hypernative, supported by a dedicated SOC team. Additional security includes extensive testnet validation and planned integration with Babylon Bitcoin staking.

Breaking Down Financial Barriers

The same institutional-grade protocols that generate billions in returns are now accessible to anyone who can send a message.

This addresses a fundamental limitation in decentralized finance: while the technology has become incredibly sophisticated, it remains accessible only to crypto experts. TAC changes this by integrating proven protocols with platforms people already understand and trust.

Celebrating Our Community

This breakthrough reflects the work of developers who believed sophisticated finance should serve everyone, DeFi protocols that trusted TAC with their ecosystems, and validators securing the network. The achievement belongs to everyone who envisioned financial tools that actually work for mainstream users.

Developer Ecosystem and Immediate Access

For Users: Live DeFi protocols provide immediate access to sophisticated financial strategies through Telegram. Start earning yield on Curve Finance, participate in Bancor's automated trading, or access Euler's lending markets directly through your messaging app.

For Developers: Comprehensive SDKs and documentation at docs.tac.build enable existing Ethereum applications to deploy unchanged while gaining Telegram integration. An upcoming hackathon featuring over $50,000 in prizes will showcase next-generation applications built on TAC's infrastructure.

For Protocols: TAC enables mainstream market access while preserving existing security models and operational frameworks. Integration maintains proven functionality while dramatically expanding addressable markets.

Expanding Access to Advanced Finance

TAC addresses the gap between DeFi's technical sophistication and mainstream accessibility. By enabling direct interaction with proven protocols through familiar platforms, the network expands the market for sophisticated financial services to users who were previously excluded by technical barriers.

The technical foundation supports complex financial applications while maintaining the security and functionality that institutional users require. This creates sustainable growth opportunities for protocols seeking broader adoption and users seeking access to advanced financial tools.

What’s next for TAC

TAC is working to onboard and port DeFi primitives (such as Swap, Yield, and Borrow primitives) directly inside apps available on Telegram, effectively making it seamless for users to access Defi from their smartphones. 

The TAC team is already working with leading Telegram games, consumer apps, and content platforms to scope and integrate DeFi use cases. This enables app developers to bring proven, battle-tested DeFi primitives directly to Telegram users and builders.

The Telegram MiniApp ecosystem is expanding rapidly, with games, user-generated content platforms, and shopping apps seeing growing global adoption. At the same time, crypto-native MiniApps like Market.win, launched on Day 1 of TAC Mainnet, are redefining how prediction markets are distributed and powered by DeFi under the hood.

A strong DeFi backbone is essential to power the dApps and primitives that will be distributed through consumer apps. With Mainnet, TAC is launching a long-term incentives program, providing substantial rewards to whitelisted Day 1 dApps: Curve, CarbonDeFi, Morpho, Euler (and EulerSwap), Zerolend, and more.

In parallel, vault providers are migrating liquidity from Ethereum Mainnet to TAC Mainnet. This capital will be deployed to strengthen DeFi primitives and ensure a robust foundation for launch.

While TAC’s core value proposition is bringing robust DeFi to TON, enabling EVM capabilities directly within Telegram unlocks even greater potential for both developers and users. By tapping into the EVM developer ecosystem, TON can leapfrog forward and bring a decade of Ethereum innovation into the Telegram-native world.

While DeFi is the foundational focus, there is a massive opportunity for developers, companies, and everyday users to bring new use cases to Telegram, starting with identity. Innovations in verifiable credentials, attestations, social graphs, and decentralized reputation systems can now be integrated into consumer apps, unlocking a wave of possibilities. Expanding into primitives like identity will enable new functionality for a wide range of users, including DAOs, which can operate more efficiently directly within Telegram.

The infrastructure is operational. The protocols are proven. The billion-user platform is ready. The journey is about to start.
