@StackOverflowExcept1on thanks, can you detail a little bit more the problem here?

@grandizzy alloy::consensus::SidecarBuilder::build() return BlobTransactionSidecar (https://docs.rs/alloy/latest/alloy/consensus/struct.SidecarBuilder.html#method.build) https://github.com/foundry-rs/foundry/blob/63010f4bd0a9a97cbba515bde44619196f4b2dfd/crates/cheatcodes/src/script.rs#L231

We should probably make it possible to specify which EIP to use after merge of https://github.com/alloy-rs/alloy/pull/3067.

it will continue to work for a bit, because will force convert this after osaka,

but def something we can switch once osaka is active
