your approach is correct! however this PR is incomplete, please request for review at least after passing the CI or it would be inefficient for requesting changes to fix the CI, on the other hand, feel free to request for review if you want to identify if you are in the right direction ( the answer is yes for the current PR! )

1. CI is not passed
2. need to merge the transient storage with storage in the token parser in codegen ( add a new field to Storage for identify if the passed struct is transient or not )
3. missing handlers in the host function registry https://github.com/zink-lang/zink/blob/main/codegen/src/wasm/host.rs

Sorry for the late! Everything looks good now! Please fix the CI 🙏

In case you don't know how to process tests locally

# test all tests
cargo tt 

# build all examples
cargo be

# test all examples
cargo te

# run clippy to all packages
cargo cc

@clearloop i'm missing something with the exports

[clearloop]

we don't need HostFunc::TransientOp since it is actually HostFunc::Evm now ^ ^

yeah true but the inability of the example to not find the transient macro is suprising

@clearloop i think i need help here

[clearloop]

Just import-export issues ))

   | help: a trait with a similar name exists: `TransientStorage`

   = note: this error originates in the attribute macro `zink::transient_storage` (in Nightly builds, run with -Z macro-backtrace for more info)

this is not pointing to the proc-macro but the path zink::transient_storage::TransientStorage in your quote haha

@clearloop transient storage is not present yet in revm cachedb

Oh I saw it, because it is temp storage, in this case, we just need a set_get call to verify our implementation

[clearloop]

You mapped the wrong opcodes for transient storage, please don't trust AI's outputs for the opcodes, comparing them with evm.codes please

[malik672]

@clearloop done
