Today the settlement chain runs bilaterally and in sequence: an asset manager allocates a trade, the allocation is matched with the broker and passed to custodians and clearing participants, each of whom checks and enriches the data before instructing the next. Synapse replaces that with one shared view of the settlement-instruction workflow. It enriches trades with standing settlement instructions from DTCC's central matching service CTM, then sends settlement instructions to everyone in the chain at the same time so the parties can process in parallel. Participants connect over API or SWIFT using ISO 20022.
HKEX announced Synapse in November 2020 and named Digital Asset as the vendor building it, on Daml smart contracts, with DTCC linking it to DTCC's Institutional Trade Processing services. The problem it targets is timing: Mainland China settles T+0, which leaves overseas investors in other time zones very little room to complete post-trade steps.
