24/7 Tokenized Collateral Mobility

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

W-D. Tokenized-collateral eligibility (505) -> 24/7 cross-network collateral mobilization (513) -> haircut/valuation (508). Frames the DTCC tokenized-collateral wedge: moving eligible collateral across networks on a 24/7 basis. Educational estimator, not a settlement instruction.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this whole workflow on the server and check one field that answers a real question.

Question: A sharp mark-to-market move hits the book and the margin call balloons. Can the collateral we already hold still cover it?
Run the AINumbers MCP tool `run_chain` with {"chain":"wholesale-settlement-collateral-mobility"} and read `513-margin-call-collateral-mobilizer.shortfall`.
Re-run with `inputs` for `513-margin-call-collateral-mobilizer`, reusing the values that result echoed, with `portfolio_mtm` set to -5000000. Compare the same field.
Verify: call `verify_execution_hash` (https://mcp.ainumbers.co/mcp) with `claimed_hash` set to `composite_execution_hash` and the full `composite_artifact`.
Ledger, for a human re-check: https://ledger.ainumbers.co/
PII rule: send synthetic or anonymised inputs only. The MCP server runs these kernels and logs no payloads.
