# Security & Trust

> Trust assumptions, ledger integrity, and the auditable lineage between off-chain assets and on-chain representations.

Strata is honest about what it enforces mechanically and what requires trust.
This page lays out the trust assumptions and the integrity guarantees that
underpin the system.

## Trust assumptions

<AccordionGroup>
  <Accordion title="Off-chain legal enforceability" icon="scale-balanced">
    Ownership of a real-world asset is ultimately a legal claim, anchored in real
    entities and governing documents. The on-chain representation is only as sound
    as the off-chain legal structure behind it — which is why Strata uses
    institutional-grade SPVs and an SEC-registered transfer agent.
  </Accordion>

  <Accordion title="Oracle and valuation inputs" icon="gauge">
    Collateral valuation depends on oracle adapters and approved valuation
    methodologies. The Risk Committee governs oracle sources, haircuts, and
    methodology; oracle override is an explicit emergency power.
  </Accordion>

  <Accordion title="Custody of reserves" icon="vault">
    srUSD and srSILVER are backed by reserves held in SPVs. Holders trust that
    those reserves are custodied and accounted for as described.
  </Accordion>

  <Accordion title="Agent and policy bounds" icon="robot">
    Autonomous agents operate within policy ceilings. The integrity of those
    bounds depends on the policy layer and the Risk Committee's parameters.
  </Accordion>
</AccordionGroup>

## Ledger integrity & ownership lineage

Strata maintains an **auditable lineage** between the off-chain record of truth
and the on-chain representation. Ownership changes are coordinated as
deterministic state transitions, so every position can be traced back through
the deal lifecycle to its originating asset and legal vehicle.

<Info>
  Strata does not claim a token *is* the asset. It maintains a verifiable chain of
  custody and ownership across the [on-chain / off-chain boundary](/concepts/onchain-offchain-boundary),
  reconciled by a canonical data model and state machine.

## Risk management as a live function

Collateral ratios, issuance caps, redemption-pool capacity, and concentration
limits are not set-and-forget. They are governed parameters, actively managed by
the Risk Committee, with emergency powers (pause, quarantine, oracle override)
held in reserve for stress events.
