It is does not provide the FROST functionality as a standalone library to be used in development of other services. - A Substrate based project that implements Threshold ECDSA Distributed Key Generation Protocol (https://github.com/webb-tools/dkg-substrate). Besides using another signature scheme (ECDSA), it is not a library that can be easily used by other projects. -Outside the Substrate / Polkadot / Kusama ecosystem ZCash Foundation has recently announced the first stable release of a FROST implementation (https://zfnd.org/frost-reference-implementation-v1-0-0-stable-release/), but has yet to integrate it in its ecosystem. There have been attempts in the past to implement off-chain threshold signing schemes, specifically by Zengo (https://zengo.com) and more recently in Solana (https://zengo.com/introducing-solanas-first-open-source-threshold-signature-library/). However, their implementation is based on an older protocol that is less efficient than the FROST protocol (https://github.com/ZenGo-X/multi-party-eddsa). +Outside the Substrate / Polkadot / Kusama ecosystem, we have found the following: +- ZCash Foundation has recently announced the first stable release of a FROST implementation (https://zfnd.org/frost-reference-implementation-v1-0-0-stable-release/), but has yet to integrate it in its ecosystem. +- There have been attempts in the past to implement off-chain threshold signing schemes to blockchain related projects, specifically by Zengo (https://github.com/ZenGo-X/multi-party-eddsa).
