Browse by domain
Start from your area of work to see relevant case studies, patterns, and vendors. Jurisdictions and compliance frameworks overlay on every domain.
Custody
Wallet ops/KMS/HSM, freeze/blacklist controls, segregation, recovery, post-trade hooks. - Governed regulator access (view keys / proofs) and evidence logging.
Data & Oracles
Price feeds, ISO/SWIFT messages, disclosure anchors, and oracle trust models. - Bind settlement to signed facts; anchor commitments/roots for audit.
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.
Identity & Compliance
KYC/AML credentials, allow/deny, accreditation, attestations, revocation. - Public verification without publishing PII; scoped disclosure for regulators.
Payments
Institutional cash movement: payouts, PvP, DvP cash legs, workflow/memo privacy. - Stakeholder-only visibility with selective disclosure; ISO/SWIFT linkage when needed. - Measure latency/finality/costs on target L2/app-chain; avoid HTLC brittleness.
Post-Quantum Threats
A Cryptographically Relevant Quantum Computer (CRQC) breaks ECDSA, BLS, ECDH, Groth16, PLONK/KZG — Ethereum consensus, execution, and application privacy layers all affected. - Harvest Now, Decrypt Later (HNDL) means confidentiality-critical applications face urgency now, even though CRQC is years away. - Hash-based and lattice-based primitives provide migration paths; STARKs are already PQ-safe.
Trading
Execution privacy: RFQ intent/size/price, pre-trade leakage control. - Cross-domain atomicity (DvP/PvP) without HTLCs; optional zk-SPV for strong atomicity.
