question: how to set fee for upload of wasm file proportional to wasm file size?

[dzmitry-lahoda]

I am trying to add spam protection against contract files uploads.

I spent hour searching here or in Osmosis how to set fee for upload (on top of usual gas TX), but failed.

How can I ensure to set custom fee for upload?

There is not message-specific fee setting. The gas parameters you can change are:

1. Transaction size limits in CometBFT
2. Wasm size limits (MaxWasmSize)
3. The compile cost per by (CompileCosts in GasRegister). This is charged for every upload where the contract is compiled once from Wasm to a module.

The last one is probably the closest to what you are looking for.
