Connect a wallet, choose an asset, and sign the action you want to take. The contracts record your deposits, debt, and position ownership on-chain. ## Choose a task | Task | What happens | Guide | | ------------------------------- | ---------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------- | | Borrow USDHN | Deposit collateral into a Trove and mint USDHN to your wallet. | [Borrowing and liquidation](/protocol/borrowing-and-liquidation.md) | | Supply or borrow a market asset | Supply an asset to a lending market, or borrow available liquidity against your account's collateral. | [Lending markets](/protocol/lending.md) | | Deposit USDHN into Earn | Deposit into a branch's Stability Pool. The pool receives interest and collateral from liquidations. | [USDHN and Earn](/protocol/usdhn-and-earn.md) | | Stake KAIA | Deposit KAIA and receive bKAIA shares. Unstaking creates withdrawal tickets, followed by a separate claim. | [bKAIA and HNKAIA](/protocol/bkaia-and-hnkaia.md) | | Mint or redeem HNKAIA | Exchange supported Kaia LSTs for a share of a multi-asset vault, or redeem shares for vault assets. | [bKAIA and HNKAIA](/protocol/bkaia-and-hnkaia.md) | | Swap or provide liquidity | Exchange assets in StableSwap, or deposit pool assets and receive LP tokens. | [StableSwap DEX](/protocol/stableswap-dex.md) | | Build a leveraged position | A Zapper combines borrowing and asset conversion to increase collateral exposure and debt. | [Leverage and loops](/protocol/loops.md) | | Transfer across chains | Select a bridge route, source network, destination network, and recipient in Convert. | [Swaps and bridges](/protocol/stableswap-dex.md) | ## How USDHN connects the product A borrower opens a **Trove**, deposits collateral, and receives newly minted USDHN. Each Trove has its own collateral, debt, interest rate, and NFT identifier. USDHN then has three main uses: * Deposit it into Earn to receive the selected Stability Pool's interest and liquidation proceeds. * Exchange it for other assets, or pair it with another token to provide liquidity. * Redeem it through the protocol for collateral, paying the redemption fee. Repaying USDHN reduces the borrower's debt. Closing a Trove repays its outstanding debt and releases the remaining collateral. A redemption by another USDHN holder also reduces a Trove's debt and collateral according to the redemption order. ## Lending and CDP borrowing **Borrow** creates USDHN debt in a Trove. Its liquidation condition uses the Trove's collateral ratio and the selected branch's rules. **Market** supplies and borrows existing assets through lending pools. Collateral and debt across the lending account determine its health factor. A health factor below 1 places the account in the liquidation range. The two systems maintain separate positions and debt. Depositing into one does not repay a loan in the other. ## Staking assets **bKAIA** represents a share of staked KAIA in the bKAIA vault. The amount of KAIA represented by a share follows the vault's accounting. Receiving KAIA back requires an unstaking request, a waiting period, and a claim. **HNKAIA** represents a share of a KAIA-denominated vault holding supported LSTs such as stKAIA, wGCKAIA, and bKAIA. Its mint and redemption amounts depend on the vault's assets and conversion rates. USDHN and HNKAIA also include OFT cross-chain transfer contracts. A bridge transfer has a source-chain transaction and a separate destination-chain delivery. ## Approvals and execution Token approval gives a specified contract permission to spend an amount of a token. The deposit, swap, or borrowing transaction then performs the selected action. Zappers combine several protocol operations into one transaction after the required approvals. Transaction previews show the amounts, costs, and resulting position before signing. [Account and common questions](/overview/general.md) explains account navigation and points. [Risk disclosure](/security/risk-disclosure.md) describes the conditions that change or reduce a position's value. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.hann.finance/overview/about-hann-finance.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
