[dependencies]
merlin = { version = "3.0.0", default-features = false, features = ["std", "nightly", "debug-transcript"] }
default = std

The std feature is set by default whenever merlin is added without default-features = false somewhere in the dependency tree.

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
