Sentry is the institutional settlement layer for tokenized equities, treasuries, and private securities — a protocol-native replacement for the DTCC, NSCC, and ATS stack, engineered from first principles for clearing, issuance, and transfer at internet speed.
Sentry is a protocol-native replacement for the central infrastructure underneath U.S. capital markets — re-implemented in software that runs on a permissionless base, with the capabilities institutions actually need.
The Depository Trust & Clearing Corporation is the central nervous system of U.S. equity markets. It clears every trade. It holds every share. It processes every dividend, corporate action, and brokerage transfer. It moves $2.15 quadrillion a year on $103 billion of participant deposits. And the system that does it was designed in 1973.
Sentry rebuilds that system — the clearing, the depository, the transfer agency, the netting — as one protocol. Same job. Different century.
Permissionless transactions clear atomically. Qualified participants opt into epoch-based settlement with multilateral netting and bilateral credit, replicating the capital efficiency of a central clearinghouse on a permissionless base.
Issuers tokenize equity and debt directly on the protocol, with qualified-participant gating, transfer-agent semantics, and lifecycle rules expressed in code. The six-day brokerage transfer becomes a single state transition.
Each venue runs inside its own validator subnet, encrypting order flow from competitors and preserving execution privacy. A global coordinator orders commitments and verifies ZK proofs — assets and balances remain composable across the whole protocol.
Programmable token issuance, qualified-participant gating, and instant transfer-agent semantics. Replaces manual cap tables and the six-day ACATS transfer.
ATS-grade order-flow privacy via per-application validator subnets. Composable with shared state — token balances, collateral, and settlement coordinate across the protocol.
Qualified-participant infrastructure with epoch-based settlement, multilateral netting, and bilateral credit. The capital efficiency of a clearinghouse without the central intermediary.
