Welcome to TACEO

TACEO provides a privacy layer for applications that need to compute on sensitive data without exposing inputs. Our finance solutions sit on top of integrable privacy services, all powered by the TACEO Network, a production MPC network already running at global scale.

We're best known for our identity work: TACEO Network is a privacy backbone for global-scale identity systems, with services used by World and zkPassport. We're now bringing the same stack to onchain finance through Merces.

Build private payments on the chain you already use​

Finance Solutions​

Private payments on the EVM chains you already use, built on Merces. Merces wraps ERC-20s like USDC into private balances, with compliance primitives at the protocol layer.

Live on Arc, Base, and Plasma testnets. ~5M demo transactions, ~300 TPS, sub-cent gas on L2. Mainnet deployment in progress. The MPC protocol underneath is the same one TACEO co-architected for World's iris-code system, in production at global scale.

Looking for design partners. Stablecoin issuers, fintechs, and payment infrastructure teams shipping private rails to production. Talk to us.

Other paths​

Privacy Services​

OPRF, Proof, OMap

Production-ready privacy primitives you can call directly: privacy-preserving nullifiers (TACEO:OPRF), private proof delegation (TACEO:Proof), and confidential shared state (TACEO:OMap).

Use this if you are: an application developer adding a single privacy feature without taking on a full payment system.

TACEO Network​

The MPC network underneath

Understand how the network enables verifiable collaboration over encrypted data, the security model, and governance. The same MPC foundation TACEO co-architected for World's iris-code system runs in production at global scale.

Use this if you are: a partner, technical stakeholder, or potential node operator evaluating the foundation everything else builds on.

Collaborative SNARKs​

coCircom, coNoir

Experiment with collaborative zero-knowledge workflows in an MPC setting. Run custom circuits and coSNARK-based systems locally. Distinct from TACEO's managed services.

Use this if you are: a crypto developer, researcher, or privacy-tech experimenter.

Where TACEO is today​

  • Finance Solutions. Merces is live on Arc, Base, and Plasma testnets with ~5M demo transactions, ~300 TPS, and single-digit-cents gas on L2. Mainnet deployment in progress.
  • Privacy Services. TACEO:OPRF and TACEO:Proof are in production for partners including World and zkPassport.
  • TACEO Network. The MPC infrastructure underpinning all of the above is built on the same foundation TACEO co-architected for World's iris-code system, in production at global scale.
