# Technical Specifications

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.
