sapling-crypto

This repository contains an implementation of Zcash's "Sapling" cryptography.

no_std compatibility

Downstream users of this crate must enable the spin_no_std feature of the lazy_static crate in order to take advantage of no_std builds; this is due to the fact that --no-default-features builds of lazy_static still rely on std.

Nomenclature

All types in the sapling-crypto crate, unless otherwise specified, are Sapling-specific types. For example, PaymentAddress is documented as being a shielded payment address; we implicitly mean it is an Sapling payment address (as opposed to e.g. an Orchard payment address, which is also shielded).
