Our multisig implementation on Zcash is designed to support both shielded and transparent transaction flows, taking into account the unique cryptographic architecture of the Zcash protocol.

Transparent Multisig

Transparent Zcash addresses follow the standard Bitcoin-style UTXO scripting model, enabling familiar M-of-N multisig via P2SH and legacy scripts. This provides full compatibility with existing wallets and infrastructure.

Shielded Multisig (Coming soon)

Shielded pools (Sapling and Orchard) do not support on-chain scripts or native M-of-N spending logic. To enable multisig, we use FROST, Zcash’s threshold Schnorr signature scheme.

FROST allows multiple key holders to collaboratively produce a single valid shielded spend signature without reconstructing the spend key or revealing that multisig was used. The resulting signature is indistinguishable from a normal shielded spend, preserving privacy and protocol compatibility.
