Cosmos x TAC: Onboarding 1 billion Telegram users to crypto

Built for Scale: TAC Runs on Cosmos + EVM Telegram as a Distribution Layer for Web3 Wrap-up: Devs, Meet a Billion New Users

The next wave of web3 won’t be about niche tools or even the tech itself. It’ll be about distribution.

Most projects build big, expensive tech first, pray to find product-market fit, and then often struggle to attract users. The Open Network (TON) blockchain is flipping the script by bringing web3 infrastructure directly to Telegram, which has more than 1 billion users worldwide.

And we’re amped that TAC has chosen Cosmos as its home to build its EVM-compatible app layer.

TAC has decided to build its new EVM-compatible L1 chain on the Cosmos SDK, which can serve up EVM apps and on-chain experiences right inside Telegram via its unique TON-Adapter technology. No rewriting code, learning new frameworks, or dealing with messy frontends. TAC’s unique approach to Hybrid dApps means you can build an app in Solidity, and have Telegram users access it via their Telegram wallets and the embedded mini-app suite.

Whether you’re a Solidity developer or just someone curious about where blockchain is heading, this is one of the clearest signs that mass adoption is closer than we think and a blueprint for hacking the distribution dilemma.

Here’s a quick look at how Cosmos brings it all together.

Built for Scale: TAC Runs on Cosmos + EVM

TAC is a fully sovereign Layer-1 chain, but it didn’t have to reinvent the wheel. It’s built using the Cosmos SDK, the same modular framework powering some of the most performant chains in the space.

As TAC co-founder Marco Monaco shared, TAC explored building an L2, or even an Ethereum fork — but found that Cosmos is the only stack where a sovereign EVM L1 could be built, with full technical liberty to achieve their vision. No limitation in token/gas configuration, full control over the software written, and no dependency with other networks.

“Cosmos is the best way to build a Sovereign L1. There’s an incredible ecosystem of partners to use, and it’s the most battletested stack. If you look at any successful L1, usually Cosmos is underneath.”

TAC’s implementation of Cosmos EVM gives Ethereum developers:

Native Solidity support
Ability to deploy EVM apps on TAC as Hybrid dApps, that Telegram users can access
High throughput, fast finality, and lower fees than L1 Ethereum

For developers, this means you can deploy dApps on TAC using the same stack you already know with no rewrites or new tooling. You get Ethereum compatibility, Cosmos compatibility, and with better UX and distribution baked in.

For users, this means more apps at your fingertips, without the need to leave Telegram or to create new wallets. Plus, in addition to the hundreds of apps available on TAC/TON, you now get access to a massive ecosystem of 120+ connected by IBC and an opportunity to take advantage of the best Cosmos and Ethereum products and services from a single place.

Build once in Solidity, distribute instantly to Telegram. That’s the unlock.

Telegram as a Distribution Layer for Web3

Telegram isn’t just another messenger. With more than 1 billion users, built-in crypto wallets, and a growing MiniApp ecosystem, it’s becoming a Web3-native super app.

TAC integrates directly with Telegram and TON, enabling EVM-based dApps to:

Launch inside Telegram with zero downloads
Settle in TON or TAC-native tokens
Reach users instantly with no wallet friction

This is business model gold. Developers get in-app usage, Telegram users get native access to DeFi, games, and tools, and chains like TAC avoid the “build it and hope they come” problem.

How TON Adapter Connected TAC EVM layer and Telegram

Wrap-up: Devs, Meet a Billion New Users

TAC’s arrival to Cosmos means native interoperability with 120+ chains powered by IBC and Eureka, while Cosmos EVM and TON Adapter enable Ethereum and Telegram to work in lockstep for both developers and users.

This creates a rare moment where incentives align across tech, capital, and audience. TAC is the first mover, and Cosmos delivers the framework to make it work.

For developers: deploy with the tools you already know and reach the world’s most active crypto user base — Telegram.

For everyone else: With Cosmos and TAC, Ethereum apps are becoming accessible to a billion users inside an app that everyone already has on their phone.
