Vanna is a credit layer on Stellar (Soroban). You can lend into Vanna’s pools, or open one margin account, borrow up to 10x against it, and use the loan in Stellar DeFi: swaps on Soroswap and Aquarius, and supply on Blend. One health factor covers the whole account. Live app: test.vanna.finance (choose Stellar in the chain switcher at the top right; the first visit asks for an access code)
This guide describes Stellar testnet at test.vanna.finance. Get test tokens from Deposit → Test funds in the app header, pick the exact USDC variant (BLUSDC, AqUSDC or SoUSDC) the pool or venue needs, and keep some XLM for fees and reserves.

​
Three steps to start

1

Install a wallet and switch it to Testnet

Install Freighter (OneKey also works) and set its network to Testnet. See Connect Your Wallet.
2

Connect

Open test.vanna.finance, enter your access code if asked, choose Stellar in the chain switcher, then click the connect button at the top right and approve the connection in your wallet.
3

Mint test tokens

Click Deposit in the header. Under Test funds, press Mint all, or Mint one token at a time: XLM (Friendbot), BLUSDC (Blend faucet), AqUSDC (Aquarius faucet) and SoUSDC (Soroswap faucet).
Portfolio account modal with Deposit and Transfer tabs, Test funds tiles for 10,000 XLM, BLUSDC, 1,000 AqUSDC and SoUSDC each with a Mint button, a Mint all button, and a Receive panel with the Freighter address and QR code

The Portfolio account modal: one-click test funds on the left, your receive address and QR code on the right. Click the image to zoom.

​
The app at a glance

The header groups the pages the way money flows: The Deposit button and your wallet name sit at the top right. A small Assist tab on the right edge of every page opens a guide that explains what you’re looking at and can hand you over to Copilot.

​
Supported assets

The three USDC tokens are different contracts, each priced at about $1. Blend uses BLUSDC, Aquarius uses AqUSDC and Soroswap uses SoUSDC. Borrowing one does not give you another.
Blend supply receipts and Soroswap / Aquarius LP positions held in your margin account also count as collateral.
A wallet signature is not the final result. Wait for the confirmation and refreshed balances before the next step that depends on it.
