A vault's observed share price, day by day

Balances are ledger entries against a sandbox provider.",        "CONVERSION_RATES_ARE_MARKET_QUOTED_OR_REFUSED: A conversion is priced only by an external venue that quotes independently of TCB.

The client holds no keys and moves those tokens only through this API; each sub-account's shares and tcbUSD are book entries against what that wallet holds.",        "INTEGRATION_AGREEMENT_ONLY: Fees as published on the rate card; no yield share, no return commitment."      ],      "summary": "This is a pilot integration on a testnet.
