Q1 2026 — Pyth Entropy Onchain Fees

[KemarTiti]

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.

Next Steps

This proposal focuses exclusively on fee implementation strategy.

We welcome input from all stakeholders:

• Service Provider

• Entropy Users

• Committed Pythians

Your insights will be valuable in refining this proposal and guiding the DAO’s decision-making process.

Below charts mostly use data collected internally until of mid of December, 2025. A public Dune Dashboard exists here, but may have errors due to more recent contract upgrades.

Shown below are the monthly averages of randomness request fulfilled per chains and average cost associated. You can find the table here.

Abstract → 0.000003 ETH

The service provider fee has been very stable and has been charging less than $0.06 (0.000019 ETH) throughout the year. Charging an additional 0.000003 ETH ($0.01) at the protocol level seems reasonable and should not impact willingness to use Entropy on Abstract.

Apechain → 0.02 APE

The service provider fee has been very stable and has been charging about $0.004 (0.02 APE) throughout the year. Charging an additional 0.02 APE at the protocol level seems reasonable as it keep the cost to use Entropy on Apechain below $0.01 (at current prices).

Arbitrum → 0.000003 ETH

There is barely no usage of Entropy on Arbitrum but I do not think this comes from a pricing/cost issue as the competition (VRF provider) on Arbitrum also charge not only the underlying gas cost to send tx but also a handful of cents extra. I would suggest charging about $0.01 (0.0.000003 ETH) at the protocol level, in line with Abstract.

B3 → 0.000003 ETH

Similar to Arbitrum, there is no usage for Entropy on B3 and the price charged by the service provider is insanely low. I’d suggest just applying the same protocol fee as for Arbitrum and Abstract of 0.000003 ETH.

Base → 0.000003 ETH

Entropy usage on Base has nicely grown in the second part of the year. Given the competitor landscape and pricing (multiple cents on top of the gas cost), I would suggest applying the same protocol fee as other mainstream L2s: 0.000003 ETH, which is sub $0.01 at current prices.

Berachain → 0.01 BERA

While the service provider fee has substantially increased throughout 2025, the nominal cost is still insignificant (about $0.001) per request. I would suggest applying a 0.01 BERA ($0.005) fee at the protocol level.

Blast → 0.000003 ETH

Entropy usage on Blast was primarily stemming from Infinex (Craterun, Bullrun) which demonstrated well the scalability of Entropy.

I would recommend the same fee value of 0.000003 ETH for the protocol on Blast — matching Abstract, Arbitrum et al.

Etherlink → 0.025 XTZ

Entropy usage never really took on Etherlink, therefore I would suggest applying the standard pricing of around $0.01 (0.025 XTZ) to still be attractive cost wise to builders.

HyperEVM → 0.0004 HYPE

Entropy on HyperEVM is now seeing a sustained usage, despite rather ‘significant’ service provider fee ($0.2) primarily led by a very fluctuating gas costs. I’d suggest charging 0.0005 HYPE (about $0.015 at current prices) as this user base seems rather not fazed by cost.

Kaia → 0.2 KAIA

The recent usage on Kaia is pretty much a single daily randomness request per day from one user. The service provider cost has remained in between 0.15 and 0.25 KAIA (about $0.01). I would suggest charging 0.2 KAIA at the protocol level given the low onchain usage.

Monad → 0.2 MON

While the base service provider fee is set at 0.4 MON (and now capped at 10 MON), the average service fee has been approx. 0.42 MON (sub $0.01). This is caused by a rather volatile, and at times significant, gas demand on Monad.

With a significant traction for Entropy on Monad (current December data indicates much more usage than in November), and being a relatively new ecosystem, pricing should be conservative. Therefore I’d suggest applying a 0.2 MON protocol fee.

Optimism → 0.000003 ETH

There’s barely no Entropy usage on Optimism, therefore pricing increase will not impact much today’s user base. Service provider fees have trended down and are currently cheap. I would suggest using the same baseline as for other major L2s above, and apply a 0.000003 ETH protocol fee.

Sanko → 0.002 DMT

Usage of Entropy on Sanko has slowly been trending to zero. Therefore, any increase in cost/fees will not have any direct impact. I would suggest applying 0.002 (DMT) as protocol fees (about $0.01).

Sei EVM → 0.1 SEI

The service provider fee has been relatively stable and cheap (sub $0.01) throughout the year. I would suggest applying a 0.1 SEI fee at the protocol level.

Soneium → 0.000003 ETH

Entropy usage on Soneium has been rather sticky throughout the year. The service provider fee has also remained very stable throughout the year (about $0.01). As for the other L2s mentioned here, I would recommend applying the 0.000003 ETH baseline fee.

Sonic → 0.1 S

Entropy usage on Sonic is quite sporadic but seems to have, for now, settled on the low end. Despite rising service provider fee, the overall cost is still very cheap as total cost been approx. $0.0035 til now.

I would suggest applying a 0.1 S fee (sub $0.01) at the protocol level.

Story → 0.01 IP

Usage, while low, has been growing on Story — the service provider fee is significantly cheap too (1/3 of a penny). I would suggest applying a 0.01 IP baseline fee at the protocol level.

Unichain → 0.000003 ETH

There’s been no usage of Entropy on Unichain. As for other L2s, I would just suggest establishing the protocol fees at 0.000003 ETH, which still makes Pyth Entropy cheaper than the competition.

Zetachain → 0.2 ZETA

Entropy usage on Zetachain has been sporadic but when it was used, it was in bursts. The service provider fee is still pretty cheap, therefore I’d suggest applying a 0.2 ZETA fee at the protocol level. Such should not impact much the future downstream usage.

[Dbxcel]

Looks like you gave it some thought.

What might be helpful is seeing a tabled comparison of current price, recommended price, and competitor price.

[KemarTiti]

Hey @Dbxcel

The table in the 1st post does expose the current total cost and the new (recommended) one

Regarding the competition cost, here are some benchmark comparison:

• Chainlink

If I’m following correctly, Chainlink VRF is actually super expensive where costs can be close to 30$ – referenced here: VRF Billing | Chainlink Documentation

• Gelato VRF

Gelato charges a dynamic amount too and it’s determined as a % premium on top of the tx cost - Pricing & Rate Limits - Gelato

Guesstimating, Gelato costs do seem rather in line (on some chains) as the one suggested above ; close or below than $0.01.

There are other oracles / protocols offering RNG or VRF but IMO the above are the ones I hear about, not others.

[lowkeigh]

As usual, very well put together @KemarTiti .

I think all of the proposed changes are completely reasonable and fully support this proposal.
