Background
On December 9th, 2025, the Pyth DAO, via the OP-PIP-87 and The Pyth Token Phase 2 discussion, mandated the Pythian Council to (1) design a pricing matrix, and (2) apply pricing changes on-chain via OP-PIPs on a quarterly basis for all Pyth Products (excluding Pyth Pro).
This post will solely focus on Pyth Entropy fees. Onchain fees for other products like Core or Express Relay have their dedicated posts.
Until this OP-PIP vote and decision, there had been little to no work to implement DAO-owned fees for the Entropy protocol.
Entropy has been designed to charge fees on a per-request basis. The total fee is the sum of:
-
the provider fee, which is determined by the individual provider on a per-blockchain basis
-
the protocol fee, which is subject to Pyth governance decisions also on a per-chain basis
You can review the current fees charged in the documentation here. The protocol fee being at the minimum value possible (1 wei), the fees you currently see in the documentation are solely the provider fee.
As of today, Entropy has been deployed on 19 blockchains, all listed here.
Implementation Strategy
Fee Structure Considerations
Fees will be based on three core principles:
-
Per-request model: Fees apply to each individual randomness fulfilled
-
Proportionality: Fees should stay reasonable relative to overall blockchain transaction costs
-
Balance: Fees paid by the end users are the sum of 2 parties (provider and protocol fee), therefore it is paramount to balance the fee charged by both parties
It is paramount to understand that the provider fee is dynamic. Indeed, in Entropy design a provider must respond (via a transaction) to the requester which means that the provider will include the current gas cost experienced onchain. We will use the current Average Provider Fee to determine the protocol (i.e. DAO) fee.
Proposed Fee Structure
The table below is a recap of all suggested change (or not) for all chains supported by Pyth Entropy.
