Blocks, negotiated directly.
Tell the desk the denomination, size, and terms you need. Every block settles with the same exact conservation as a one-unit trade.
Institutional
Compute at desk scale.
OTC and institutional access to compute, settled on the same rail everyone else uses.
Size without slippage.
Large blocks move over the counter, negotiated directly and settled line for line on the FK1 rail. Same conservation, same receipts, same grades as the public book.
Receipts you can audit.
Every line carries a grade and a receipt you can verify yourself. Nothing about institutional access lowers the evidence bar.
Talk to the desk.
Write through the waitlist marked INSTITUTIONAL with the denominations and size you are working with.
