There was a problem hiding this comment.
we need to add expected function call (resolveTimeout) to digest. This will help block signature reuse on other functions if they have similar params.

The structure of digests is not enforced. i.e. there is no mechanism to make sure each digest has address, evmxSlug and nonce. lets enforce this somehow.
