Merces: Private Onchain Finance
Public blockchains expose everything by default: balances, counterparties, amounts, transaction flows. That's a dealbreaker for real financial operations.
TACEO's finance solution, Merces, let developers, institutions, and AI agents move value on the chains they already use without putting their business on a public ledger.
Wallet balances, token transfers, DeFi positions, and much more are no longer publicly accessible information. Merces encrypts these values and securely manages them as secret-shares across the TACEO Network. Any state transitions are verified onchain via ZK Proofs (coSNARKs), and no single party — including TACEO — sees the underyling data. Compliance primitives are built into the protocol, not bolted on top.
Merces is an integrable privacy layer for the chain you already use. Two things set it apart:
- We come to you. Merces deploys on the chain you already use. No migration, no new asset.
- Solutions, not primitives. A ready-made solution you can plug into a stablecoin or fintech product, not raw cryptographic building blocks you have to assemble.
- Integration made simple. Our SDKs and APIs let you integrate Merces in your existing wallets, apps and interfaces.

Features
Private virtual account
An encrypted balance on the chain the user is already on, standalone or alongside their public one. Deposit, transfer, withdraw, and read your own history — without publishing any of it.
Best fit:
- Payroll, treasury, and B2B settlement that can't be public
- Stablecoin issuers and fintechs offering confidential accounts
- White-labeled privacy rails inside an existing product
Private DeFi
Put a private balance to work without exposing positions, counterparties, or strategy. Yield today, with swaps and further composability in development.
Best fit:
- Treasuries earning on balances they can't disclose
- Traders and LPs who would otherwise broadcast strategy
- Regulated deployments that need privacy and audit together
Compliance
Sanctions and AML screening before a transfer settles, and scoped disclosure of past activity to authorised parties afterwards — through MPC, not surveillance infrastructure.
Best fit:
- VASPs and regulated entities on private payment rails
- Fintechs integrating Merces who need compliance in the flow
- Auditors and compliance teams needing scoped reveal
Private RWAs
Tokenize funds, credit, or securities without publishing the cap table. Holdings are encrypted commitments, secondary transfers hide holder, counterparty and size, and the asset stays on the chain it already lives on.
Best fit:
- Issuers whose investor register can't be public
- Funds and credit vehicles blocked on tokenization by disclosure
- Regulated assets needing scoped audit rather than full exposure
Merces also underpins Confidential x402, drop-in privacy for agent-to-agent payments over the HTTP 402 standard. See Agent Solutions.
