@mykhail that’s fantastic! I’ll DM you and we can talk more.
We don’t plan to support 256-bit integers because it’s kind of narrow – we don’t think a lot of people would use it. Moreover, you can use decimal(38,0) to get up to around 38 digits of precision. So it’s a great use case for Wasm. Do you have more details you can add? Like, did you use open source code in your Wasm function and if so, can you share the git repo?
