Privacy protocols let users transact on Monad without publicly exposing balances, token holdings, amounts, or counterparties, typically using zero-knowledge proofs, sometimes combined with multiparty computation (MPC).

TACEO Merces

TACEO Merces is a privacy layer that wraps existing ERC-20 tokens into private balances. Balances and identifiers are secret-shared across the TACEO Network, a set of independent MPC nodes, so no single node sees a readable balance. Each state change is verified onchain with a collaborative zero-knowledge proof (coSNARK) before it takes effect. Users keep their existing wallets, and the token itself is unchanged. On Monad mainnet, Merces supports private USDC with limited users and volume caps. Registration, deposits, and withdrawals require a compliance attestation. See TACEO’s deployments and status page for current contract addresses and feature availability. You integrate Merces with the TypeScript client @taceo/merces-client, which also ships a taceo-merces-client CLI with a --chain monad preset.
