Summary
This proposal introduces a refinement to the Buyback & Distribute (BBD) mechanism to make it more sustainable and market-adaptive.
The change would cap staking rewards at 10% APR, leaving any excess GMX on Fee Handler contract as Overhead.
Accumulated Overhead can later be released when protocol fees are low or token price is high — making GMX distribution counter-cyclical and self-balancing over time.
Motivation
The BBD program has now operated for a full year, with approximately 1,625,000 GMX tokens bought back from protocol fees (amounting ~ $28M).
However, data shows that:
-
The total staked GMX has barely increased,
-
The free float remains unchanged, and
-
Most distributed GMX is sold shortly after receipt.
As a result, BBD has not achieved its intended goal of supporting or stabilizing the GMX price. Currently, the mechanism behaves like an ongoing emission source — creating sell pressure instead of building long-term buy support.
Problem Overview
-
Emission pressure is continuous, regardless of market conditions, fee environment or token price.
-
GMX distributed as rewards tends to re-enter the market shortly after distribution.
-
No feedback loop exists to throttle emissions in strong protocol performance periods or boost yield support when activity slows.
-
Funding fee farmers exploit high-APR periods by temporarily buying and staking GMX while simultaneously shorting to collect funding fees. After high-APR phases end, they unstake and sell both the principal and accumulated rewards, effectively extracting value from long-term stakers and adding sell pressure during market normalization.
Proposal Specification
1. Introduce a 10% APR cap for GMX staking rewards.
-
When APR exceeds 10%, reward emissions are limited and excess GMX is accumulated as Overhead.
-
When APR falls below 10% (fee revenue declines), the Fee Handler should gradually release stored GMX to maintain a smoother yield curve.
2. Accumulate Overhead inside the Fee Handler contract.
-
Overhead balance represents undistributed buyback GMX held by the protocol.
-
These tokens remain out of circulation until distributed later.
3. Keep the buyback process unchanged.
-
Only the distribution logic would be updated.
-
Buybacks continue to convert protocol fees into GMX, preserving existing economic flow.
Expected Outcomes
-
Counter-cyclical stability — the system accumulates GMX when token price is low or fees high, and releases it when price rises or fees slow. -
Reduced immediate sell pressure — more GMX remains locked inside Fee Handler during high-APR phases. -
Smoother yields — staking rewards become more predictable week-to-week. -
Self-balancing tokenomics — aligning emission pressure with real protocol performance.
Empirical Data
Below is the dataset showing the real buyback history and the modeled outcome under the proposed 10 % APR cap.
Benefits
-
Market stability: Converts BBD from constant emission into an adaptive buffer.
-
Sustainability: Prevents excessive short-term emissions while maintaining healthy yield levels.
-
Flexibility: Overhead buffer can be used strategically — released manually or via automated conditions for example random airdrops to stakers.
-
Simplicity: Minor parameters adjustment without protocol redesign, contract changes, audits or 3rd party integrations breaking.
Drawbacks / Considerations
-
Slight reward delay for stakers during high-fee periods (shouldn’t be problem for long term holders).
-
Transparency of accumulated Overhead should be ensured via public view function or dashboard integration.
-
Main concern for stakers: accumulated GMX may never be fully distributed. Therefore, a strict disclaimer must apply:
All accumulated GMX (Overhead) may only be used for future staking rewards (in GMX or esGMX form) and cannot be redirected, repurposed, or burned for any other use.
Governance Disclaimers
-
The modified BBD mechanism should operate for at least one full year to realize it’s full potential before any new tokenomics or distribution changes are introduced.
-
During this period, no overlapping proposals affecting emissions or staking rewards should be enacted.
-
After one year, data should be reviewed to evaluate success and determine next steps.
Next Steps
-
Gather community feedback on proposal and APR cap level (default 10 %, adjustable).
-
Submit final on-chain governance vote for proposal implementation.
