A Go library implementing multi-party threshold signature schemes (TSS) for ECDSA and EdDSA, based on the Gennaro-Goldfeder CCS 2018 protocol. It provides keygen, signing, and resharing protocols so multiple parties can jointly create signatures without any single party holding the full private key.

Use cases

• implement threshold ECDSA wallets where multiple parties co-sign transactions
• split a private key into shares so no single server holds the full key
• build MPC-based custody for crypto exchanges
• reshare signing keys when participants join or leave a group
• sign blockchain transactions without revealing which parties participated
• replace on-chain multisig with privacy-preserving threshold signatures

When to choose

• you need t-of-n threshold signing for secp256k1 or Ed25519-style curves in Go
• you want a well-known, MIT-licensed TSS implementation with keygen, signing, and resharing
• you're building non-custodial wallets or custody infrastructure on chains like Bitcoin, Ethereum, or Cardano

When to avoid

• you need a ready-made CLI or service rather than a developer library
• your signatures don't need threshold or multi-party properties
• you can't follow the library's security implementation notes - misuse can break security guarantees
