Confio

(2020–2025)
We built software in the web3 space and brought the smart contract framework CosmWasm into existence.

It was a great ride but it came to an end. That is unfortunate, but it's okay. The OSS we built remains publicly available and we hope it is a strong foundation for whatever comes next.

Cheers, Simon (Co-founder and liquidator of Confio GmbH)

As of July 1st 2025 Confio GmbH is in liquidation. The company is expecting a clean wind down with all outstanding invoices settled mid 2026. This is most likely the last post on this account.

We had great fun building cool tech since 2020 with a stellar team and the best users.

Thank you to all of our supporters and supporters of the technology we built. You motivated us to keep going during difficult times over the years.

🎂CosmWasm just turned 6 — that’s like… 42 in #blockchain years.

From "hello world" contracts to powering real interchain apps, we’ve come a long way.

Still #Wasm. Still spicy. Still cooking.

Happy Birthday to the smart contract king of @cosmos.👑
