Priority Fee Distribution: PIP-65 / PIP-85

This page explains observed PIP-65 priority-fee distributions and the PIP-85 specification for Polygon Chain, also known technically as Polygon PoS. For general fee mechanics, start with Polygon Chain Fees. For how POLTRACK measures batches and validator income, see Methodology & Data Sources.

PIP-85 status — September 10, 2026: staker fee sharing is inactive in POLTRACK. It is not modeled, displayed, or included in staking APR, charts, or scenario allocations. The specification and former model remain documented for reference; they do not operate in the current product. Observed PIP-65 payments remain tracked.

What PIP-65 Changed

PIP-65 changed how Polygon PoS priority fees are redistributed after block production. Instead of treating all transaction fees as a single economic bucket, priority fees are routed into distribution pools.

Under the PIP-65 model tracked by POLTRACK:

PoolShareRecipient logic
Block producer pool26%Directed to the elected block producer
Validator pool74%Distributed across validators by performance-weighted stake

These distributions happen in batches, not as smooth daily wallet payments. POLTRACK treats observed payments as realized distribution facts and keeps them separate from modeled daily fee generation.

What PIP-85 Specifies

PIP-85 specifies a change to the downstream economics of the PIP-65 validator pool: a staker/delegator share and an adjusted remaining validator-pool formula.

The PIP-85 formula specifies:

Block producer pool = 26% of total priority fees
Staker / delegator pool = 50% of the 74% validator pool = 37% of total priority fees
Remaining validator pool = 37% of total priority fees

The specification weights the remaining validator pool by equality and performance rather than only the earlier stake-weighted approach. These documented percentages are reference parameters, not an active staker fee model or evidence of payouts in POLTRACK.

POLTRACK currently displays emission-funded network staking APR only. It does not calculate or add a PIP-85 fee component in the frontend.

Why It Matters

Priority fees connect network usage to validator and staker economics. When transaction activity rises, the fee pool can become a more important part of staking economics. When activity falls, emission can dominate the yield picture.

PIP-65 and PIP-85 are important for:

  • validator income comparisons;
  • understanding the proposed staker fee path, currently inactive in POLTRACK;
  • fee distribution transparency;
  • analysis of how Polygon PoS activity flows back to network participants.

How POLTRACK Tracks PIP-65

POLTRACK reads PIP-65 distribution transactions from the Polygon PoS multisig and maps payments to validator records. The validator analytics product shows batch history, total received, pool share, and recent trend.

Validator fee share = validator PIP-65 amount / total validator pool

Realized PIP-65 validator payments, the retained but inactive PIP-85 reference model, and future claimable/claimed PIP-85 artifacts are separate data concepts. Legacy stored data and API compatibility fields are retained; the frontend does not use them to model or display staker fee income.

For the live product, see Polygon Validators. For the product guide, see the Polygon Validators guide.

Data Limitations

PIP-65 batches can lag the underlying fee collection period. A payment observed on one date may represent fees collected earlier. POLTRACK therefore treats batch payment date, fee collection period, and validator state as related but not identical facts.

PIP-85 activation and distribution mechanics should be read from the canonical PIP text and public implementation evidence. The official fee calculator includes PIP-85 allocation logic, but an aggregate calculated staker pool is not evidence of an individual claim or payout. POLTRACK keeps staker fee modeling disabled until activation is verified and it is explicitly enabled in the product.

Common Questions

What is PIP-65?

PIP-65 is the Polygon PoS fee redistribution model that routes priority fee income to a validator pool and a block producer pool.

What is PIP-85?

PIP-85 specifies 50% of the PIP-65 validator pool for stakers/delegators, equivalent to 37% of total priority fees. This staker fee model is currently inactive in POLTRACK and does not contribute to displayed yield or simulations.

Does PIP-65 income go directly to delegators?

PIP-65 tracks validator-side fee distribution. Delegator economics depend on validator commission, staking mechanics, and later fee-sharing policy such as PIP-85. Under PIP-85, delegator/staker fee sharing is a separate distribution path rather than the same thing as historical PIP-65 validator payments.

Why are payments batched?

The redistribution flow is settled periodically. That creates observable batch payments rather than a smooth daily payout stream.

How should I compare validators using PIP-65 data?

Compare total received, number of batches, pool share, and recent trend. Do not compare one batch in isolation.
