A lending account holds supplied assets and debt together. One account can hold several assets, and one wallet can own several accounts. Risk checks evaluate collateral and debt within the same account. Collateral held in another lending account or in your wallet does not back this account’s debt.

​
Ownership

Opening an account mints a position NFT to its owner. Supply and debt balances are recorded on the account; there are no separate transferable supply or debt tokens.
Transferring the position NFT transfers control of the entire lending account, including its collateral and debt. An NFT transfer approval lets the approved address move that ownership token.
The account’s spoke is fixed when the account is created. Moving the NFT to another wallet does not change the spoke or remove the account’s debt.

​
Who can act on an account

A delegate must be a position manager approved and active under governance, and must also have permission from the account owner. NFT transfer approvals and account delegation are separate permissions. Grants made by a different owner do not authorize an account after its ownership changes. A stored grant can become active again if the NFT returns to the granting owner. This can happen when an intervening owner has neither replaced nor cleared the stored grants. Revoke unwanted delegates explicitly; transferring the NFT does not delete those grants.

​
Balances and limits

Supplied balances and debt reflect accrued interest. Repaying debt reduces what the account owes; withdrawing reduces its supplied collateral. The configured position limits restrict how many distinct markets an account can supply or borrow. Each limit is at most five. Adding to an existing supply position does not consume another slot. Existing positions remain usable after governance lowers a position limit, subject to the other action checks. A market is identified by its hub and token; the same token in another hub counts as another position. Assets with fewer than three decimals must be the account’s only supplied market. Borrowing and withdrawals with debt must pass the borrowing limits and health factor checks. Repayment does not require those collateral checks. A missing price or risk value does not mean the account has no debt.

​
Close an account

Repay all debt, then withdraw all supplied assets. The protocol closes an empty account and burns its position NFT. Supplying into a new account creates a different account and ownership token. Account and NFT interfaces are in the account integration guide and position NFT reference.
