Fees
Summary
| Fee | Paid in | Who sets it | Goes to |
|---|---|---|---|
| Gas (L2 execution + L1 data) | ETH | ArbOS pricing; governance sets the minimum base fee | Network fee accounts, then split by AEP (below) |
| DEX swap fee | The input token | Governance, per pair: default 0.30%, at most 1% | Liquidity providers; one sixth of it to the protocol when a fee recipient is set |
| Offering | — | — | No contract-level fee |
| Dividends and redemptions | — | — | No contract-level fee |
| AssetHub bond | Bond token (e.g. USDC) | Governance sets the minimum | A deposit, not a fee; refundable except for slashed amounts, which go to the slash sink |
| Issuer fees | Off-chain | The issuer | Disclosed in the asset's documents |
Gas
Each transaction pays for the L2 compute it uses and for the Ethereum data needed to post it. Blob data keeps the L1 part small; in AnyTrust mode it is smaller still. The ERC-4337 paymaster, when deployed, can sponsor gas for common holder actions (claiming dividends, subscribing and claiming units).
Arbitrum Expansion Program (AEP)
Primcast settles to Ethereum, so it takes part in the Arbitrum Expansion Program. Gas revenue, net of L1 data cost, is routed through reward distributors: 90% to the Primcast treasury and 10% to the Arbitrum Foundation. The split applies only to gas revenue, not to application fees.
What Primcast does not charge
The application contracts take no cut of subscriptions, dividends, redemptions or transfers. Any platform fee an issuer charges is set out in that asset's documents and collected off-chain or through the issuer's own flows.
