Funds & Assets

Asset lifecycle: issuance, transfers, registry linkages, portfolio moves. - Hide amounts/positions; preserve DvP finality; bridge legal records via attestations. - Derivatives: daily deltas/margins hidden; regulator replayable audit. - Pick cheapest viable privacy that meets audit needs; measure costs under 4844.

Building blocks for funds & assets privacy

Shielding

Enable confidential transfers by shielding balances, sender, and receiver, while still allowing regulators and auditors to verify via selective disclosure (viewing keys, proofs). The logic generalizes beyond ERC-20 to any transferable asset.

Crypto-register bridge (eWpG) with EAS mirroring

Operate with a licensed crypto-register today while mirroring key legal facts (issuance, transfers, liens) as on-chain attestations. The registrar remains the legal source of truth; the on-chain anchor provides tamper evidence and paves the way for later automation once regulation allows.

CR: None OS: Partial P: Full S: Medium

ICMA Bond Data Taxonomy (canonical terms/events)

Use the ICMA Bond Data Taxonomy as the canonical schema for bond terms and lifecycle events. A shared data model avoids fragmentation across issuance platforms, registrars, and regulators, and provides a stable foundation for attestations and zero-knowledge proofs over bond data.

CR: None OS: Yes P: Full S: High

Selective disclosure (viewing keys + zero-knowledge proofs)

Provide on-demand, scoped visibility into confidential trades and positions via threshold-controlled viewing keys or zero-knowledge predicate proofs that answer specific regulator questions. The institution keeps plaintext private by default and releases only the minimum information required to satisfy a specific, logged mandate.

Who builds funds & assets privacy tooling

Paladin

Open-source (Apache-2.0) privacy layer under the [Linux Foundation Decentralized Trust](https://github.com/LFDT-Paladin/paladin). Paladin provides the common wallet/vault functions that are needed to interact with all forms of privacy preserving smart contracts. It also provides a model for atomic programmability across these privacy preserving smart contracts, harnessing the power of the underlying EVM shared ledger.

Aztec Rollup

Aztec is a privacy focused rollup (or zk-zk-rollup) on Ethereum that enables private transactions and programmable privacy. It is a fully programmable network where applications can access both private and public state.
