Setl

LedgerSwarm from Setl is a distributed ledger orchestration layer for financial institutions that delivers real-time settlement across ledgers using the RLN concept. It treats the settlement of a financial transaction as a set of ledger updates that the system orchestrates, requiring every party to digitally sign the settlement proposal before it is finalised, which produces an atomic transaction across all ledgers involved.

The project states that the product works with existing core banking and custody systems, giving institutions tokenization capabilities without reengineering their underlying ledgers, while maintaining an immutable global transaction order. Listed use cases cover internal settlement, cross-border and cross-currency settlement, and connectivity to external ledgers, with entries for pilots, developer documentation and demo requests.
