S𝛑PETs (Sustainable Practically Indistinguishable Privacy-Enhanced Transactions) is universal covert private transactions scheme. A generalization of Bitcoin’s CoinSwap for any public blockchain that supports ECDSA or Schnorr.

It uses two-party computation (2PC) with adaptor signatures to achive fully scriptless transactions and verifiable timed commitments (VTC) for failed swap resolution.

A Rust libp2p transport for {t,n}-threshold signature schemes based on GG20, a full multi-party computation (MPC) algorithm for threshold ECDSA with support for identifying malicious parties.

Structured around the virtual “room” abstraction and the “Single Proposer; Multiple Joiners” model with echo broadcast as a reliable broadcast scheme.
