Canton Securities Lending 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.

Assess collateral swap eligibility and HQLA classification for Canton securities lending. Swap direction assessment → HQLA tier and haircut verdict.

Export Artifacts

Download the §4 chain definition artifact (hash-anchored composite JSON) or the §13.11 W3C Verifiable Credentials view. Both derive from the chain definition — no new hash is minted. Available after hash computation.

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: Does this collateral swap, an IG bond leg against a UST leg, clear the eligibility validator for booking?
Run the AINumbers MCP tool `run_chain` with {"chain":"canton-securities-lending"} and read `515-collateral-swap-eligibility-validator.eligibility`.
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.
