Fees
This page lists every fee you can pay when you use the Meddleware tools, who receives it, and the current default amount.
Current defaults, may change
The amounts below are the current defaults. Meddleware reviews them regularly and can change them: the platform's commission terms are held in a shared on-chain setting, and the other fees are set in the apps. The app always shows the exact amount before you approve, and your wallet shows it again when you sign. Check the figure in front of you, not this page, before you pay. These figures describe testnet; Getting started says which networks are live.
SUI amounts are written in SUI. For reference, 1 SUI is 1,000,000,000 MIST, the smallest unit.
Fees paid to Meddleware
Meddleware receives these at the platform treasury, whose address and balance anyone can see in the Treasury.
| What | Current default | When you pay it |
|---|---|---|
| Commission on an access pass sale | 0.2% of the price, but never less than 0.0005 SUI and never more than 10% (a limit enforced by the contract) | Each time a pass is bought from a gate. It comes out of the price, so the buyer pays no extra |
| Minimum price of a paid pass | 0.005 SUI | Not a fee: the lowest price a gate owner can set (ten times the minimum commission) |
| Free-gate fee | 1 SUI, once per gate | When a gate owner creates a free gate (price 0), or makes a gate free for the first time |
| Airdrop commission | the commission a sale at the gate's price would pay | When a gate owner gives passes away from a paid gate |
| Token issuance fee | 2 SUI, once per coin | In the transaction that publishes a new coin with Token Issuance |
| Upload relay fee | 0.0001 SUI plus 1 MIST (0.000000001 SUI) per KiB of the encoded file, which Walrus makes several times the file size plus a fixed overhead. In practice about 0.00016 SUI for a small file, 0.00021 SUI for 10 MiB and 0.0006 SUI for 100 MiB. The app will not pay more than 0.005 SUI | With each upload through Meddleware's Walrus relay |
| Upload pass for Meddleware's relay | 0.005 SUI for 10 uploads (0.0005 SUI an upload), soulbound | When you buy a pass in Walrus Storage |
The pass price goes to Meddleware in full: the relay's pass is sold by the platform, so both the gate owner's share and the platform's commission are Meddleware's. On a gate that someone else owns, only the commission goes to Meddleware and the rest goes to that gate's payment recipient.
Meddleware sizes the small per-use fees (relay fee, the pass share per upload, the commission floor) to stay a small share of what the action costs you on the network anyway, and the one-off fees (free gate, coin issuance) well below comparable services.
Fees paid to others
| What | Paid in | Paid to | Amount |
|---|---|---|---|
| Walrus storage | WAL | the Walrus network (its storage nodes) | Depends on the file size and the number of epochs. At mainnet prices on 2026-10-19, a small file costs about 0.010 WAL for one epoch, and about 0.2 WAL for 53 epochs; a 10 MiB file about 0.017 WAL for one epoch |
| Network gas | SUI | Sui validators | A small, variable amount for every transaction. Approximate figures below |
| Seal key servers | not charged by this app | n/a | Sealed Storage adds no fee for key servers |
Approximate network gas per action on mainnet, estimated from testnet measurements (your wallet shows the exact figure; testnet gas can differ):
| Action | About |
|---|---|
| Buy an access pass | 0.0044 SUI (mostly the storage of the pass, returned if the pass is later burned) |
| Spend one use of a pass | 0.0001 SUI |
| Create a gate | 0.0053 SUI |
| Register a Walrus blob (storage start) | 0.0031 SUI |
| Certify a Walrus blob | 0.0001 SUI |
| Publish a coin with Token Issuance | 0.019 SUI |
Making a coin needs your wallet to allow up to 0.5 SUI of gas as a budget. That is a ceiling, not a charge: you pay only what is used.
Things with no fee
- Reading anything: the Treasury, the dashboard, status and these docs.
- Sealing and opening files in Sealed Storage: no Meddleware fee, and signing the message is free. Only publishing a discovery pointer costs gas.
- Creating a paid gate (apart from gas).
- Transfers of a coin made with Token Issuance: your coin never charges fees on its own transfers.
- Signing a message to prove you hold a pass.
