Canton MMF Collateral Eligibility Chain

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.

Question: Can this tokenized money market fund be pledged as collateral, or do its liquidity and NAV terms make it ineligible? Run the AINumbers MCP tool `run_chain` with {"chain":"canton-mmf-collateral"} and read `514-tokenized-fund-collateral-validator.eligibility`. Re-run with `inputs` for `514-tokenized-fund-collateral-validator`, reusing the values that result echoed, with `fund_type` changed so fund_type is sec_inst_prime_mmf with nav still 1. 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.
