Canton Securities Issuance 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.
Reading mode (READINESS-BUILD): These checks can be gathered in any order; the sequence below is for convenience. Regulatory classification and Daml lifecycle validation each check a separate fact about the security and are combined into one readiness answer, not an executed issuance.

Live Execution

This page is the chain definition (plan). To run the chain step by step in your browser, with each step's kernel executing in-page and a composite hash over the outputs, open the live runner:

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 tokenized note issued on Canton carries an ISIN and a Daml lifecycle. Does the lifecycle validator clear it as compliant?
Run the AINumbers MCP tool `run_chain` with {"chain":"canton-securities-issuance"} and read `512-tokenized-security-lifecycle-validator.verdict`.
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.
