Available liquidity
Available liquidity describes funds currently available in the displayed market context. The Hub overview uses supplied value minus borrowed value as a simple estimate. It is not ur personal withdrawal or borrowing allowance.
When checking an action, distinguish three questions: does the market have funds, does it have room under its limits, and does ur position permit the action?
Utilization
Utilization describes the share of supplied liquidity being borrowed. In the simple example above, 600 divided by 1,000 is 60%. A changing percentage reflects changing market use, not the percentage of ur wallet invested.
A Hub’s utilization and a Spoke’s credit-line usage have different denominators. Do not compare them as though they measure the same limit.
Supply and borrowing capacity
Market caps restrict how much activity is allowed. A cap can limit new supply or borrowing even when a wallet has tokens or the market has liquidity.
The expanded Spoke row displays supply and borrow capacity reported by the protocol. These are market-level figures, not a promise that your full wallet balance can be supplied or that your position can borrow that much. Your transaction preview checks the specific request.
Cap headroom describes remaining room against a displayed cap. Other settings can still stop the action. If a button is unavailable, read its reason instead of relying on one capacity number.
Spoke credit lines
A Hub can limit the amount a Spoke draws for an asset. A credit line describes that market-level authorization, not credit granted to ur personal wallet.
This explorer’s Spoke credit-line total combines its connected Hubs. The selected Hub context changes the asset routes u are browsing; it does not make that aggregate total a single-Hub figure.
