MPC protocols for threshold ECDSA

PoC implementation of Gallois Field, Paillier, DSA, ECDSA, and curve secp256k1 with an adapted scheme of "Two-party generation of DSA signatures" by MacKenzie and Reiter

Threshold MPC wallet for AI Agents

MPC-TSS is a project to demonstrate the working of our threshold signature scheme leveraging the security of X1 hardware wallet

CyChain is a non-collusive & massively decentralized access control network. This repository contains the working proof of concept to demonstrate it's scalability.

Rust implementation of DKLs23 threshold ECDSA protocol for secure multi-party computation signing with BIP32 support

Implementation of the Fast Secure Two-Party ECDSA Signing scheme alongside its Adaptor Signature variant

Browser-based GG20 threshold ECDSA demo — Paillier encryption, distributed key generation, and joint signing without any party holding the full private key. The protocol behind Fireblocks and Coinbase MPC.

Implementation of the Fast Secure Two-Party ECDSA Signing scheme

Browser-based Paillier cryptosystem demo — Pascal Paillier's 1999 additive homomorphic encryption. Encrypt, decrypt, homomorphic addition without decrypting. Private 10-voter election simulation and 5-hospital patient aggregation. The primitive underlying GG20 threshold ECDSA, Helios voting, and ElectionGuard. No backends. No simulated math.

🔐 Implement a secure, Rust-based multiparty threshold ECDSA signing service using the DKLs23 protocol for distributed key management without key reconstruction.
