Telegram has expanded its blockchain ecosystem with the mainnet launch of Tac, a new layer-1 network designed to connect Ethereum-based decentralized apps (DApps) to The Open Network (TON). The launch opens a direct path for Ethereum Virtual Machine (EVM) applications to integrate with TON and Telegram environments.
Tac enables Telegram users to access Ethereum DeFi protocols such as Curve, Morpho, and Euler directly through the messenger app. The announcement came on July 16, as Tac confirmed its mainnet is now live.
No Code Rewrite Required
Tac serves as an EVM-compatible blockchain built on TON. It offers developers a way to deploy existing EVM DApps on TON without rewriting code for the TON Virtual Machine (TVM). This direct compatibility simplifies integration with Telegram’s Mini App ecosystem, which exclusively supports TON-based applications as of early 2025.
According to Tac co-founder Pavel Altukhov, the platform unlocks exposure to Telegram’s massive user base by bridging previously isolated DeFi protocols to TON.
Tac Runs Independently of TON and Telegram
Although Tac connects EVM DApps to TON and Telegram, it is operated by a separate team. A Tac spokesperson confirmed that the project works independently from both Telegram and the TON Foundation.
Tac was first announced in July 2024. It features its own jetton token—a TON-based crypto asset similar to Ethereum’s ERC-20 tokens—and collaborates with other TON ecosystem projects to support network value.
Tac co-founder Marco Monaco said the design helps “accrue value to TON” while expanding Ethereum’s footprint into Telegram’s ecosystem.
$11.5M Raised Ahead of Mainnet
Tac raised $11.5 million across two funding rounds. The $6.5 million seed round in November 2024 was followed by a $5 million strategic round in early 2025 led by Web3 investment firm Hack VC.
The launch arrives amid Telegram’s decision to restrict Mini App support to the TON blockchain only. This move forced many developers to find new ways to adapt EVM apps for TVM. Tac now offers a direct route for Ethereum projects to stay connected with Telegram without rebuilding apps.
Telegram’s TON-only policy sparked debate among developers and users. Critics said it undermined decentralization. However, TON Foundation board member Steve Yun defended the decision, citing scalability and security as key reasons for limiting support to TON.
With Tac’s mainnet now live, EVM developers have a new gateway to bring their applications to Telegram and the broader TON ecosystem without friction.
Toncoin Risks Breakdown After Descending Triangle Formation
Toncoin TON/USDT has formed a descending triangle pattern on the daily chart between April 1 and July 17, 2025. A descending triangle is a bearish continuation pattern that develops when the price creates lower highs while holding horizontal support. This structure often signals a breakdown once the support line gives way.
In this case, the triangle formed below the 50-day exponential moving average (EMA), now at $2.99. As of July 17, Toncoin trades at $3.17 on OKX, but the pattern shows strong resistance from the upper trendline and a flat base near $2.60. If the pattern confirms a breakdown below this level, the projected drop could reach nearly 75 percent from the current price, targeting $1.80.
The large green arrow on the chart reinforces this bearish scenario, pointing directly to the $1.80 support zone. Volume data shows no clear uptick to support a breakout. Instead, the current movement remains inside the triangle. Until Toncoin invalidates the triangle by closing above the upper resistance, the threat of a breakdown remains active.
Toncoin Approaches Overbought Zone as RSI Surges
Toncoin’s Relative Strength Index (RSI) on the daily chart reached 64.56 on July 17, 2025, nearing the overbought threshold of 70. The RSI is a momentum indicator that measures the speed and change of price movements, with values above 70 indicating overbought conditions and below 30 suggesting oversold levels.
The current RSI reading reflects rising buying pressure after Toncoin climbed above its 50-day exponential moving average at $2.99. The yellow signal line, a moving average of the RSI, stands at 51.42 and trails the RSI curve, confirming recent upward momentum.
However, the steep ascent in RSI shows the market may be nearing exhaustion. If the RSI crosses 70, it may trigger selling pressure, especially as Toncoin remains inside a descending triangle structure. While the RSI does not yet confirm an overbought reversal, its fast rise adds weight to the possibility of a price rejection if resistance holds.
Toncoin MACD Turns Positive as Bullish Momentum Builds
Toncoin’s Moving Average Convergence Divergence (MACD) indicator turned bullish on July 17, 2025. The MACD line crossed above the signal line at 0.046, while the histogram flipped green, confirming positive momentum. The MACD measures trend direction and momentum by tracking the relationship between two exponential moving averages—commonly the 12-day and 26-day.
The crossover suggests a potential short-term uptrend. The histogram’s steady rise above zero also shows strengthening bullish pressure after weeks of sideways movement. Although the crossover is mild, the signal marks the clearest upside momentum since early June.
However, this MACD setup comes as Toncoin trades inside a descending triangle pattern. While the MACD supports bullish continuation, the pattern’s upper trendline still acts as major resistance. Until Toncoin breaks above that resistance with strong volume, this momentum may remain limited.
