The project provides reference implementations of the ERC-7573 and ERC-8087 Decryption Oracles. For details see the corresponding module sites below.

ERC-7573 (DvP) Decryption Oracle

For details see finmath decryption oracle for encrypted hashed keys (ERC-7573)

The interface to the decryption oracle proxy contract and the decryption oracle callback is published as @finmath.net/dvp@0.8.0. The vendored interfaces and the 4.0.1 key-oracle release implement that exact package version.
