Glossary
The terms you will meet in the tools, in alphabetical order. Where a tool uses a different word for the same thing, both are given.
| Term | Meaning |
|---|---|
| Access gate (gate) | An on-chain object with a price and rules that sells passes. See Access Gate. |
| Access pass (pass, access NFT) | The NFT you get when you buy from a gate. Holding a valid pass is the proof that you may use whatever the gate protects. |
| Admin capability (AdminCap) | The object that lets its holder manage one gate: its price, recipient, pausing, airdrops and freezing. Whoever holds it controls the gate. |
| Aggregator | A Walrus service that serves a stored blob to anyone over plain web requests. |
| Airdrop | A gate owner giving passes away for free. The gate owner pays the commission a sale would have paid. |
| Auto-burn | A gate setting: a single-use pass that reaches zero uses is deleted instead of being kept as a spent receipt. |
| Basis point (bps) | One hundredth of a percent. 100 bps is 1%; the default commission of 20 bps is 0.2%. |
| Blob | A file stored on Walrus. |
| Blob ID | The permanent name of a blob on Walrus. Anyone who has it can read the blob. |
| Burn | To destroy an object for good, such as a pass or a capability. |
| Certify (certified) | The last step of a Walrus upload, in which the storage nodes confirm they hold the file. An uploaded but uncertified blob is not fully stored. |
| Checkpoint (block) | A numbered batch of finished Sui transactions. A higher number is more recent. |
| Coin type | The unique name of a Sui coin, in the form package::module::STRUCT. |
| Commission | The share of a pass's price that goes to the platform treasury when a pass is sold. See Fees. |
| Credit (use) | One spend of a single-use pass. The gate console calls them credits; the contracts call them uses. |
| Decimals | How many decimal places a coin has. With 9, one coin is 1,000,000,000 of its smallest unit. |
| Deletable blob | A Walrus blob its owner can remove early to reclaim unused storage. The opposite of a permanent blob. |
| Encrypt, decrypt | To scramble a file so it can be read only with a key, and to turn it back. In Sealed Storage both happen in your browser. |
| Epoch | Walrus's unit of time. Storage is paid for in epochs. On mainnet an epoch is about two weeks. |
| Explorer | A website, such as Suiscan, that lets you look up addresses, objects and transactions on Sui. |
| Faucet | A service that gives out free test SUI on a test network. |
| Free gate | A gate with price 0. It pays a one-off platform fee. |
| Freeze (frozen, immutable) | To make a gate or a coin's settings permanently unchangeable. It cannot be undone. |
| Gas | The network fee, paid in SUI, for every transaction on Sui. It goes to the network's validators, not to Meddleware. |
| Gate owner | The person who creates a gate and holds its admin capability. |
| Key server | One of the independent services that hold pieces of the keys for Sealed Storage and release them only when the on-chain policy approves. |
| Localnet | A Sui network run on a developer's own computer. Not for general use. |
| Mainnet | The real Sui network, where SUI has value. See Getting started for whether the tools are live there. |
| Manifest | The small file Sealed Storage gives you after sealing a file. It points to the encrypted file and is needed to open it. It holds no secret. |
| MetadataCap | The capability to change a coin's description and icon. Frozen metadata deletes it. |
| Mintable | A coin whose holder of the TreasuryCap can create more. The opposite of fixed supply. |
| MIST | The smallest unit of SUI. 1 SUI is 1,000,000,000 MIST. |
| NFT | A unique object in your wallet. A pass is an NFT. |
| Object ID | The unique address of an object on Sui. Passes, gates and blobs each have one. |
| Package | A published piece of on-chain code. Each coin has its own package. |
| Pause | To stop a gate selling new passes for a while. Reversible. |
| Permanent blob | A Walrus blob that nobody, including you, can delete before it expires. |
| Platform | Meddleware as the owner of the shared contracts and the party that receives platform fees. |
| Policy | In Sealed Storage, the on-chain rule that decides who may open a file: pass holders of a gate, or anyone after a time. |
| Recipient | The address that receives something: a gate's sale proceeds, or a new coin's capabilities and supply. |
| Relay (upload relay) | A service that takes a file from your browser and writes it to Walrus on your behalf, since a browser cannot do it directly. |
| Relay fee (tip) | A small SUI payment to whoever runs the upload relay (Meddleware, for its own relay) with each upload. |
| Seal | The threshold-encryption system Sealed Storage is built on. See Sealed Storage. |
| Session key | A short-lived key created when you sign one wallet message to open a file, so you are not asked again straight away. |
| Single-use pass | A pass with a number of uses, each spent by the holder. |
| Soulbound | A pass that cannot be transferred to another wallet. |
| SUI | Sui's coin, used for gas and for payments in these tools. |
| Testnet | A free practice Sui network whose SUI has no value. |
| Threshold | How many key servers must agree to release a key. For example 2 of 3. |
| Time lock | A Sealed Storage policy: the file opens for anyone after an unlock time. |
| Treasury | The platform address that receives commission and fees. See Treasury. |
| TreasuryCap | The capability to mint and burn a coin. A fixed supply never has one. |
| Unlimited pass | A pass that is never used up; it works as a membership. |
| UpgradeCap | The capability to replace a package's code. An immutable package has none. |
| Wallet | The browser extension that holds your keys and signs what you approve. |
| WAL | Walrus's token, used to pay for storage. Separate from SUI. |
| Walrus | The decentralised storage network the storage tools use. |
