FAQ

#Do I need an account?

No. Anyone can upload anonymously and get a share link with no signup. Connecting a Solana wallet is optional and unlocks a private drive, larger files, provenance signing, and earnings. See the Quickstart.

#Does it cost gas?

No. Logging in and signing files only sign messages — that is free and off-chain. udrive never asks you to send a transaction to use it.

#How large can files be?

• Anonymous uploads: up to 100 MB per file.
• Wallet-connected uploads: up to 2 GBper file, within a 2 GB account quota.

#Can the team read my files?

It depends on the encryption mode. Public and unlisted files are stored unencrypted (but only served via presigned URLs). Private files default to server-side encryption. Choose e2e and the file is encrypted in your browser with a wallet-derived key — udrive stores only ciphertext and cannot read it. See encryption modes.

#How do I delete a file?

Owners can delete from the drive or via DELETE /api/files/:id; the record is soft-deleted and the object is removed from storage. You can also set an expiresAt so a file self-destructs on a schedule.

#Which wallets work?

Any standard Solana wallet that can sign a message. Standard wallets are auto-detected by the connect modal — no special configuration needed.

#How do earnings & payouts work?

Opt a file into the training marketplace and set a price; earnings accrue as agents use it, visible in your dashboard. See Data sharing & earnings.

#Are files stored on-chain?

No. File bytes live in object storage (Cloudflare R2), indexed in a database. Solana is used for identity and signatures — proving who you are and vouching for provenance — not for storing the files themselves.
