Built for Regulated
Financial Institutions.
A permissioned EVM-compatible ZK chain running on your private infrastructure, anchoring state transitions to Ethereum via validity proofs. Your data stays private. Your operations are mathematically verifiable. No trust required.
Run private trading venues, tokenized funds and settlement on the same chain. Private to the market, provable to the regulator.
Use Cases
Intraday Repo & Settlement
Real-time 24/7 repo settlement with atomic DvP. Proof-backed audit trails verifiable by any external auditor or regulator, without exposing counterparty details.
Tokenized Money Market Funds
Private ERC-20 funds with automated yield distribution, settlement in minutes, and ZK proof of reserves. Full regulatory compliance without public balance sheet exposure.
Cross-Border & FX Settlement
Atomic cross-border payments with no correspondent banks and no SWIFT delays. Travel Rule compliance via ZK proof. Settlement under 5 seconds, 24/7.
Dark Pools & Block Trading
A private order book that runs on the operator's own infrastructure. Orders, positions and liquidation levels stay hidden until they match, so large trades do not move the market or get front run. A ZK proof attests every match settled by the venue's own rules and anchors that proof to Ethereum, so a regulator can verify fair execution without seeing a single order.
Private Trade Finance
Multi-party trade finance workflows where each participant proves their step was executed correctly, without disclosing commercial terms to other parties.
Regulatory Reporting
Prove aggregate risk positions, capital adequacy, and AML screening outcomes to regulators. Mathematically verifiable, no raw transaction data disclosed.
Dark Pools & Block Trading
Every order on a public blockchain is exposed before it settles. Bots front run large trades, and with positions and liquidation levels visible to anyone, institutional size gets hunted in the open. A dark pool keeps orders hidden until they match, but on a public chain that privacy has always cost the auditability regulators require. Cocoon removes the trade-off: private to the market, provable to the regulator.
Who it is for
Perpetual DEXes
Run a private book next to your public one. Big traders get hidden positions and liquidation levels, so they stop routing size to centralized desks, and the fees stay with the protocol.
Regulated institutions
Trade in size without moving the market against you. Reporting comes out as proven totals, exposure and volume, so the regulator sees the numbers, not the trades behind them.
How Cocoon Works
Cocoon stores all sensitive data off-chain in operator-controlled infrastructure.
Only commitments and proofs go to Ethereum.
Authenticate
User authenticates via SSO, LDAP, or SIWE. Identity verified against enterprise IAM systems.
Permissioned Request
Transaction routed through Proxy RPC. Permissions validated at contract, function, and argument level.
Private Execution
Transaction executes on the private sequencer. All data stays in institution-controlled database.
Ethereum Anchoring
ZK proof + state root posted to Ethereum L1 via the anchoring gateway.

Frequently Asked Questions
What is Cocoon?
Cocoon is a permissioned, EVM-compatible ZK chain for regulated financial institutions. It runs on the institution's private infrastructure and anchors state transitions to Ethereum via zero-knowledge validity proofs.
Who is Cocoon designed for?
Cocoon is built for banks, asset managers, insurers, and other regulated financial institutions that need private execution with public verification.
What use cases does Cocoon support?
Cocoon's published use cases include intraday repo and settlement, tokenized money market funds, cross-border and FX settlement, claims processing, private trade finance, and regulatory reporting.
How does Cocoon keep institutional data private?
Cocoon runs as a permissioned chain on the institution’s own infrastructure and exposes only zero-knowledge proofs to external verifiers — counterparty details and raw transaction data are not disclosed publicly.
Is Cocoon compatible with the Ethereum ecosystem?
Yes. Cocoon is EVM-compatible and anchors verification to Ethereum via validity proofs.
Can Cocoon run a dark pool?
Yes. A dark pool is a trading venue where orders stay hidden until they match. On Cocoon the venue runs on the operator's own infrastructure, so orders never touch a public mempool, and access is limited to KYC'd participants through OnchainID. A validity proof shows each batch followed the venue's rules and is anchored to Ethereum, which lets a regulator confirm fair execution without seeing the underlying orders.
