Tools as reported by the server

• list_rwa_updates
  Free cursor-based Treasury change notices. Instrument scope retains version 1; market and access scopes use version 2 and independent cursors. Source dates and digests remain distinct from retrieval times. Up to 90-day retention subject to source permissions. No paid market values or reconstruction

  Free arithmetic comparison of a saved measured USD instrument response and caller-supplied US Treasury total-return index levels with identical dates. Simple actual/365; 28-32 days. Input provenance is not verified. Spot rates, unmatched windows, quoted yields and other currencies are not comparable

  Free comparison of two supplied 402rates Treasury snapshots: yield, issuer divergence, source identifiers, calculation windows and data availability. Reports numeric threshold crossings without assigning economic significance. No new data access, authentication of snapshots, historical reconstructio

  Returns free normalized observations for one tracked instrument, one reconstructible recorder source and one inclusive date window.

• cheapest_settlement_chain
  Returns only the single cheapest chain for a USDC transfer right now, its total transaction fee in USD, the scope of that figure and how long it stays valid. Free and deliberately minimal: no per-chain table, no runner-up, no fee components and no source provenance. The paid tool compare_settlement_
• compare_settlement_costs
  Measured USDC transfer costs on Base, Polygon, Arbitrum, Ethereum and XDC: simulated gas, current token prices, fresh chain heads and applicable rollup L1 fees. Inputs and block references accompany each figure. Cheapest first; unmeasurable chains are excluded, not estimated. Business/professional u

  Realised 30-day yields for 13 tokenized treasury funds under the Open Treasury Yield Basis. Measured rows use NAV, price or verified passive-holder balances, with observations, sources and dates.
