At this time you will need to get an Arweave token (AR) and wallet to upload data onto ArDrive.
The ArDrive team is working to introduce payment by credit card in currencies like the US Dollar in 2021.
And remember, ArDrive only requires a one time fee. There are no ongoing subscription fees for storage, and never will be.
Arweave is currently offering new users 0.1 AR (enough to upload around 50 MB of data) and a digital wallet for free. Simply visit arweave.org/wallet and they’ll set you up with a pre-loaded wallet.
