XOXNO Lending is a collateralized lending protocol on Stellar Soroban. Suppliers provide assets to lending markets and earn interest. Borrowers use accepted collateral to borrow within the account's limits.
An account groups collateral and debt under one set of risk rules. Interest and price changes affect its health. If the account becomes unhealthy, liquidation can repay debt by seizing collateral; unrecoverable debt can reduce supplier balances.
Follow these pages in order to understand the main concepts and actions:
- Architecture Overview — markets, shared liquidity, spokes, and accounts.
- Health Factor and Collateral — borrowing capacity and the liquidation boundary.
- Interest Rates — how supplied balances and debt accrue interest.
- Managing Positions — supply, borrow, repay, withdraw, and account authority.
- Risk and Liquidations — liquidation, repayment incentives, and supplier losses.
Oracle System explains the prices used in risk decisions. Governance and Timelock explains administrative powers and restrictions. Security covers trust assumptions, evidence limits, and private vulnerability reporting.

- Flash Loans — borrow liquidity and repay principal plus fee before the transaction ends.
