Threshold signatures (TSS) for multi-chain vaults distribute key generation and signing across participants without exposing a full private key. This guide details ECDSA, EdDSA, and ML-DSA workflows across Bitcoin, Ethereum, Solana, and Cosmos networks.

The keygen and keysign flow in blockchain architecture defines how distributed parties jointly generate cryptographic keys and authorize transactions. This documentation outlines endpoint organization and vault key management concepts for these TSS workflows.

Yes, this threshold signature guide covers UTXO and Cosmos ecosystems, along with Solana. It details chain-type mappings and the BlockChainService coordination layer for managing vault keys across these supported networks.

To configure per-chain derivation paths for MPC vaults, you map each blockchain network to its specific derivation path standard. This guide provides architecture documentation for managing these paths and endpoint patterns across supported chains.

You should use ML-DSA workflows instead of ECDSA when your vault key management requires post-quantum cryptographic signatures. This guide documents both approaches alongside EdDSA to help security engineers audit multi-chain vault implementations.
