Substrace is a tool for linting substrate projects for specific gotchas and other errors.

Installing

Install through cargo install substrace. Run using cargo substrace.

Currently the following lints are used:

missing_security_doc: checks for the presence Security headers on storage maps using suspicious hashing functions, such as Twox64Concat.
panics: ensures that clippy has been properly configured to avoid panics in code.
missing_transactional: ensures that extrinsics are marked with the #[transactional] label
extrinsics_must_be_tagged: ensures that extrinsics are marked with the #[pallet::call_index(...)] label

More lints will be added in the future, initially targetting checks that ensure storage consistencies. Currently in the works:

storage_iter_insert: checks that storage isn't simultaniously being mutated whilst iteration is active.
enable_singlepass_benchmarks: checks that benchmarks are run when calling cargo test
xcm_config_check: checks that the xcm config does not make the same mistake as the Karura bug
