## Tools (as reported by the server, not verified)

- `read\_rwa\_access\_evidence`: Free source-backed documentation of Treasury distribution and asset-settlement protocols. Distinguishes an announced access path from an identified fund and a protocol from a deployed fund integration. Unknown fund identity, investor access and liquidity remain explicit. No live quote, execution or
- `estimate\_payment\_costs`: Free exact-decimal calculation from caller-supplied prices, fees and setup costs for a planned number of calls. Separates locked capital and batches; unknown costs stay unknown. Compares complete profiles only within the same currency. No exchange-rate conversion, external fee measurement, payment o
- `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
- `compare\_rwa\_benchmark`: 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
- `compare\_rwa\_snapshots`: 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

Every point carries value, date, source id, revision and source-time versus read-time dating. Omit source\_id to list the instrument's audited sources. The five current-
- `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
- `get\_rwa\_yields`: Realised 30-day yields for 13 tokenized treasury funds under the Open Treasury Yield Basis.
