The four functions
| Function | What it does |
|---|---|
| Liquid · trading venue | Runs a continuous limit order book per listed security, inside guardrails the issuer sets at listing. |
| Heimdall · execution | Runs every order through pre-trade checks and executes matches as riskless principal, both sides at one on-screen price. |
| Mimir · ownership record | Keeps the book-entry register. Fills write to it directly, so settlement is a record update, not a paperwork workflow. |
| Custody | Holds positions as direct beneficial ownership between holder and issuer, no pooled vehicle in between. |
