Transact is a transaction execution platform designed to be used as a library or component when implementing distributed ledgers, including blockchains.
Hyperledger Transact is a platform-agnostic library for executing transactions with smart contracts. It is now maintained as part of the Splinter Community, where it has been moved to ARCHIVED status. The project includes a core Transact Rust library, examples and reference implementations in the transact-contrib repository, and RFCs for proposed and approved changes in the transact-rfcs repository.
