Using Walrus Storage
A walkthrough of the Walrus Storage app. You'll need a Sui wallet with a little SUI.
Upload a blob
- Connect your wallet (header).
- Go to the Upload tab and choose a file.
- Pick a storage duration (in epochs). The app estimates the cost — longer durations cost more up front.
- If you hold an Access Gate pass for the gated relay, the app detects it and uses the gated relay (a capped tip applies); otherwise it uses the public relay.
- Confirm the transaction(s) in your wallet. Uploading registers the blob on Sui and stores the bytes on Walrus.
- When it finishes you get a blob ID — copy it. That's how you (or anyone) reads the content back.
Interrupted upload?
The gated flow is designed so an interrupted or retried upload doesn't waste a single-use pass — the app remembers the in-progress redemption and resumes it rather than consuming another use.
View your blobs
Open My Blobs. The app lists the Walrus blobs your address owns, with their IDs and remaining lifetime. This reads on-chain ownership directly — no extra login.
Extend a blob's lifetime
Because blobs expire, My Blobs lets you extend one before it lapses:
- Find the blob in My Blobs.
- Choose Extend and pick how many additional epochs.
- Confirm the transaction. The blob's stored-until point moves out accordingly.
Do this before expiry — once a blob has lapsed and been removed, it can't be extended, only re-uploaded.
Read a blob
A blob ID resolves through a Walrus aggregator over plain HTTP. Anyone with the ID can fetch the bytes (blobs are public unless you encrypted them first with Sealed Storage).
Common questions
Is my file private? No — Walrus blobs are public. If you need privacy, use Sealed Storage, which encrypts before storing.
Why did I sign more than once? Registering and storing can involve more than one step; the app guides you through each wallet prompt.
What does the tip do? On the gated relay, the tip covers the relay's operating cost. The app requests the minimum and caps it so you can't overpay.
