Fund escrow

Paid reads use your app identity’s Data Portability escrow balance. You only fund it — the SDK resolves the escrow contract for the network you select, so there’s no contract address to configure in your app. Escrow is funded from the Fund escrow section of the same signed-in Developers page you used to create the app identity.
1

Open and sign in to Vana Account developers

Open account-dev.vana.org/developers and sign in.
2

Confirm the network

Set the Protocol network toggle to Testnet (Moksha). Mainnet deployment is being finalized — build on testnet for now.
3

Enter the app identity address in Fund escrow

In the Fund escrow section, the Funding source is your connected External wallet. Set App identity address to the grantee app address you created or registered — this is the address that pays for Personal Server reads.
4

Enter the amount and fund

Enter the Amount of native VANA to deposit, click Fund escrow, and submit the wallet transaction.
5

Wait for the balance to update

Wait until the app’s available balance updates.
For Moksha, get testnet VANA from faucet.vana.com/moksha; the faucet dispenses 10 VANA per address per 24 hours. Data request creation and user approval can succeed before escrow is funded, but data reads fail with Insufficient finalized balance until the app address has finalized escrow balance.
Once mainnet deployment is finalized, mainnet fees will use USDC; confirm the current funding path and fee asset with the Vana team before going live.

Check current fees

Creating an access request does not spend escrow. Payment happens when your backend reads approved data from the user’s Personal Server. A paid read can include:
FeeWhen it applies
grant_registrationone-time fee for registering the user grant, when enabled
data_accessfee for a successful data read, when enabled
You don’t set or pay fees yourself. When a read needs payment, the Personal Server returns a 402 challenge with the exact amount owed; the SDK pays it from your escrow and retries. Fee amounts and assets are set by Vana onchain in FeeRegistry and can change, so treat any number below as an example, not a fixed price.
FeeRegistry: On testnet, fees currently use native VANA. In testing, the first paid read for a grant requires about 0.01 VANA from escrow because it includes grant registration plus data access. Treat that as an example, not a fixed price. On mainnet, fees use USDC. Fee assets and prices can differ by environment, so check Vana Account and FeeRegistry before funding escrow for a paid-read test.
