Review a market
Before using an asset, check its listing on XOXNO:
An asset can be collateral on one spoke and borrow-only on another. Listing an
asset in the pool does not make it usable by every account.
Listing and price availability
A usable listing needs a pool market and the relevant spoke configuration. Actions that value an account also need valid oracle prices.
A missing or rejected price is an unknown value, not a zero price. Do not use
it to estimate borrowing capacity. A price failure does not erase a market or
its balances. Repayment and some
other actions do not require prices; the oracle guide
explains the exceptions.
