One transaction may have fees going to several entities, such as the market where the asset was published, or the Ocean Community. Here are all of them:
* Publish Market: the market where the asset was published.
* Consume Market: the market where the asset was consumed.
* Provider: the entity facilitating asset consumption. May serve up data, run compute, etc.
* Ocean Community: Ocean Community Wallet.
### Publish fee
When you publish an asset on the Ocean marketplace, there are currently no charges for publishing fees :tada:
However, if you're building a custom marketplace, you have the flexibility to include a publishing fee by adding an extra transaction in the publish flow. Depending on your marketplace's unique use case, you, as the marketplace owner, can decide whether or not to implement this fee. We believe in giving you the freedom to tailor your marketplace to your specific needs and preferences.
Swap fees are incurred as a transaction cost whenever someone exchanges one type of token for another within a [fixed rate exchange](pricing-schemas.md#fixed-pricing). These exchanges can involve swapping a datatoken for a basetoken, like OCEAN or H2O, or vice versa, where basetoken is exchanged for datatoken. The specific value of the swap fee depends on the type of token being used in the exchange.
When a user exchanges a [datatoken](datatokens.md) for the privilege of downloading an asset or initiating a compute job that utilizes the asset, consume fees come into play. These fees are associated with accessing an asset and include:
* Defined during the ERC20 [creation](https://github.com/oceanprotocol/contracts/blob/b937a12b50dc4bdb7a6901c33e5c8fa136697df7/contracts/templates/ERC721Template.sol#L334).
* Defined as Address, Token, Amount. The amount is an absolute value(not a percentage).
* Ocean's smart contracts collect **Ocean Community fees** during order operations. These fees are reinvested in community projects and distributed to the veOCEAN holders through Data Farming.
* This fee is set at the [smart contract](https://github.com/oceanprotocol/contracts/blob/main/contracts/communityFee/OPFCommunityFeeCollector.sol) level.
* It can be updated by Ocean Protocol Foundation. See details in the [smart contracts](https://github.com/oceanprotocol/contracts/blob/main/contracts/pools/FactoryRouter.sol#L391-L407).
The Ocean Protocol Foundation can [change](https://github.com/oceanprotocol/contracts/blob/main/contracts/pools/FactoryRouter.sol#L391-L407) the Ocean community fees.

[Providers](../old-infrastructure/provider/) facilitate data consumption, initiate compute jobs, encrypt and decrypt DDOs, and verify user access to specific data assets or services.
Provider fees serve as [compensation](../community-monetization.md#3.-running-your-own-provider) to the individuals or organizations operating their own provider instances when users request assets.
* Provider fees can be utilized to charge for [computing](../compute-to-data/) resources. Consumers can select the desired payment amount based on the compute resources required to execute an algorithm within the [Compute-to-Data](../compute-to-data/) environment, aligning with their specific needs.
* Eg: A provider can charge a fixed fee of 10 USDT per consume, irrespective of the pricing schema used (e.g., fixed rate with ETH, BTC, dispenser).
* Eg: A provider may impose a fixed fee of 15 DAI to reserve compute resources for 1 hour, enabling the initiation of compute jobs.
These fees play a crucial role in incentivizing individuals and organizations to operate provider instances and charge consumers based on their resource usage. By doing so, they contribute to the growth and sustainability of the Ocean Protocol ecosystem.
