• list_rwa_yields read-only

  Lists tokenized real-world asset deployments (tokenized US treasuries, credit, funds) with current APY and TVL, from public DefiLlama data. Filter by chain or kind. Information only, not advice.

  Parameters:

  • kind — string — "treasury" = tokenized US government debt / money-market style
  • chain — string — Blockchain name, e.g. "Ethereum", "Solana", "Base"
  • limit — integer — Max rows (default 20)
  • sortBy — string — Sort key (default tvlUsd)
  • minTvlUsd — number — Minimum total value locked in USD (default 1,000,000)

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_rwa_asset read-only

  Returns every deployment of one tokenized asset symbol (e.g. BUIDL, USDY, OUSG) across chains, with total TVL and curated description.

  Parameters:

  • symbol (required) — string — Token symbol, e.g. "BUIDL"

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• rwa_market_summary read-only

  Totals for the tokenized treasury market: distinct tokens, total TVL, median APY, top tokens by TVL, plus totals for other tokenized real-world assets.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• compare_yield_to_tokenized_treasuries read-only

  Given an APY the user currently earns (e.g. a bank savings rate), computes the simple-interest difference versus the highest-yielding liquid tokenized treasury over a horizon. Returns arithmetic and assumptions only; it does not recommend.

  Parameters:

  • currentApyPercent (required) — number — APY the user earns today, in percent, e.g. 0.5

• list_stablecoin_yields read-only

  Where USDC, USDT, DAI, USDe and other stablecoins earn yield right now: single-asset pools on lending markets and vaults (credit and basis venues on Pro) (DefiLlama data, excludes tokenized treasuries, which have their own tools). Each row carries its protocol category group (lending, vault, credit, basis), base vs reward APY, 30-day mean APY and TVL. Default: pools with at least $10M TVL, highest APY first. Information only, not advice.

  Parameters:

  • chain — string — Blockchain name, e.g. "Base"
  • group — string — Risk/category group
  • limit — integer — Max rows (default 20)
  • sortBy — string — Default apy
  • symbol — string — Stablecoin symbol, e.g. "USDC"
  • majorOnly — boolean — Only major stablecoins (USDC, USDT, DAI, USDS, USDe, PYUSD, ...)
  • minTvlUsd — number — Minimum pool TVL in USD (default 10,000,000)

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• stablecoin_yield_summary read-only

  Per stablecoin: venues, total TVL, median APY, best venue overall and best collateralized-lending venue; totals by category group; and the median tokenized treasury APY for comparison. Pools with at least $10M TVL by default.

  Parameters:

  • minTvlUsd — number — Pool TVL floor (default 10,000,000)

  Hints: read-only yes · destructive no · idempotent yes · open-world no

  Parameters:

  • kind — string

  • issuer — string — Issuer name or part of it, e.g. "xStocks", "Ondo", "Robinhood"
