OIS Rewards Update: Y = 0 (OP-PIP-103 Implemented)

Following the passage of OP-PIP-103: Pausing OIS Rewards, the OIS reward rate parameter (Y) has been set to 0 as of April 2026.

This post clarifies what this means for stakers, publishers, and the broader Pyth ecosystem.

What Changed

The OIS reward pool depleted on April 22, 2026. Rather than allow phantom reward calculations to accumulate (which would create on-chain accounting mismatches), the Pythian Council set Y = 0 per the governance proposal.

Before: Y = 1924 → ~1.93M PYTH distributed weekly After: Y = 0 → No rewards distributed

What Remains Active

This change does not disable OIS. The staking and slashing mechanisms remain fully operational:

  • Publishers retain their staked positions and remain accountable for data quality

  • Delegators can maintain or withdraw their stake at any time

  • Slashing is still enforced for data quality violations — stake remains at risk

  • Governance staking is unaffected

The enforcement mechanism never required rewards to function — it requires stake at risk. That remains intact.

For Existing Stakers

  • Stakers can withdraw their staked tokens at any time — no lockup changes

  • Staked tokens still secure Pyth price feeds via slashing risk

  • Governance staking remains available for DAO participation

Documentation

The OIS documentation has been updated to reflect these changes. The mathematical representation now notes that Y = 0, and reward-focused examples have been archived.
