This PIP proposes aligning the initial POL Validator Rewards with the original MATIC Validator Rewards Schedule, introduced during the launch of MATIC in 2020, and ending in June 2025. The proposal is to continue, i.e. adhere to the current MATIC reward schedule, and, once it ends (in June 2025), switch to the proposed Polygon 2.0 reward schedule. This would honor the social contract, i.e. public commitment, with regards to Polygon validator rewards, and enable smooth transition to Polygon 2.0.


PIP-17, which initiates the POL upgrade, introduces a 1% annual POL emission for validator rewards. The authors propose to complete the original commitments of the genesis MATIC Validator Rewards Schedule, before commencing the aforementioned Polygon 2.0 validator reward schedule.

The original and proposed outline for emissions can be seen in the table below.

Proposed Emissions Schedule With Comparison:

Year Dates Original Reward Pool Original POL Proposed Reward Pool New Proposed Reward Pool
First June 2020 - June 2021 312,917,639 - -
Second June 2021 - June 2022 275,625,675 - -
Third June 2022 - June 2023 246,933,140 - -
Fourth June 2023 - June 2024 204,303,976 *134,700,000 *201,400,000
Fifth June 2024 - June 2025 160,219,840 101,000,000 150,300,000
Sixth June 2025 - June 2026 0 102,100,000 103,530,000

*estimated using 4 months of original schedule, 8 months of newly proposed schedule.


Adjust the implementation of DefaultEmissionManager.sol to follow the current MATIC validator reward schedule, gradually reducing the reward emission via subsequent PIPs until June 2025. In July 2025, commence the Polygon 2.0 schedule of 1% annual POL emission for validator rewards.

Great initiative!

It makes sense for the new POL emissions to follow the previously defined schedule!


We agree. This looks like a good plan to us.
