I'm really unsure why this failed.

The tests passed in 30a77d8 and failed in 25c02c1.

The only Cargo.lock changes bumped ed25519-dalek, zeroize, and rustls in db49a63 (none should have impact here).

crypto and coins were not further edited. common only had serai-db edited.

That appears to be far too many zeroes to be valid, if that is the calldata. That'd suggest a bug re: zeroization, yet ethereum-serai doesn't pull in zeroize (at least, not directly).

The tests pass locally. I'll rerun them on the CI now.
