# Jack Henry

> Core integration between the Cosmos Tokenization Suite and Jack Henry platforms, including tokenization of securities held on the general ledger.

The Cosmos Tokenization Suite (CTS) runs a digital
ledger alongside the Jack Henry core. Ledger sync is the mechanism that keeps
the two ledgers reconciled, following the same pattern as every other core
integration.

## Supported platforms

CTS currently supports SilverLake.

For other Jack Henry platforms, contact our team at [sales@cosmoslabs.io](mailto:sales@cosmoslabs.io) to
discuss an integration.

See [Integration Architecture](/banking-core-integrations/architecture) for the
applicable connection patterns and failure handling.

## Tokenizing securities held on the general ledger

The Jack Henry integration is not limited to deposits. Securities held on the
general ledger can also be tokenized through the same ledger sync mechanism:
the position remains on the core, and CTS mirrors it to the digital
ledger.

Securities and tokenized deposits therefore share the same digital ledger. This
makes settlement between them possible without moving either asset off the
bank's own books.

See [Securities](/use-cases/securities) for the use case and
[Delivery vs Payment](/settlement/delivery-vs-payment) for settlement of a
securities leg against a cash leg.

<Note>
  This page is a placeholder for the platform detail. SilverLake version
  requirements, the connection method, the setup steps, and the security types in
  scope still need to be documented.
