Telegram is opening up to decentralized finance (DeFi) on Ethereum with the mainnet launch of Tac, a third-party blockchain bridging apps on the Ethereum Virtual Machine (EVM) to The Open Network (TON).
Tac mainnet has launched with a mission to bring EVM decentralized apps (DApps) to TON and Telegram ecosystems, the team behind the network announced on Tuesday.
The network allows Telegram users to interact with EVM DApps directly within the messenger, offering access to a range of DeFi protocols such as Curve, Morpho, Euler and more, Tac co-founder Pavel Altukhov told Cointelegraph.
For developers, Tac provides EVM a frictionless way to deploy on TON without rewriting code from scratch, unlocking exposure to Telegram’s billion-strong user base.
What is Tac and why does Telegram need it?
First publicly announced in July 2024, Tac is designed to act as a full EVM-compatible layer-1 blockchain connecting Ethereum DApps to the TON and Telegram ecosystems.
According to Tac co-founder Marco Monaco, Tac is a project built on TON that features its own jetton TON token and works with other projects within the TON ecosystem to “accrue value to TON.”
The network raised a total of $11.5 million across its seed and strategic rounds last year and early 2025, with the latest $5 million strategic round being led by the Web3 venture capital firm Hack VC.
“Until recently, EVM-based applications had to be adapted for TON Virtual Machine (TVM) compatibility to reach Telegram’s 1B+ users,” Tac wrote in a post in March 2025.
“But now, Tac allows EVM developers to integrate their applications with Telegram and TON effortlessly,” it added.
This is a developing story, and further information will be added as it becomes available.
