This proposal has been reviewed internally with team efforts. I’m sharing it here to invite feedback and improve it together with the community.
TL;DR
This proposal suggests the next advancement of Astar’s tokenomics, developed after careful consideration based on community and investor feedbacks:
- Transition from dynamic inflation to a fixed maximum supply model.
- Introduce gradual emission reduction while preserving dynamic staking incentives.
- Establish Protocol-Owned Liquidity (POL) managed by the Astar Finance Committee (AFC) to independently secure Polkadot coretime slots.
- Sustain dApp staking rewards, projecting a stable 11-14% maximum APR with bonus reward at 50% staking ratio within the upcoming 2 years.
- Strengthen ASTR’s long-term economic value, resilience and independence.
Background
In August 2023, Astar introduced a dynamic tokenomics model, aligning emissions with real network participation while enhancing builder incentives and burn mechanisms to strengthen long-term sustainability.
Last month, Astar executed another update to its dynamic tokenomics parameters, further enhancing the network’s economic design by better aligning staking rewards with real network activity, stabilizing APRs, reducing unnecessary emissions, and lowering overall ASTR inflation.
Now, as the web3 landscape continues to evolve, Astar is proactively positioning itself to meet new strategic priorities and maintain its competitive edge, while supporting our broader initiatives to drive real-world Web3 adoption via Soneium and Japan:
- Growing institutional interest favors networks with fixed-supply economic models offering long-term value stability.
- Polkadot’s Agile Coretime shift requires parachains to self-finance coretime purchases through sustainable liquidity, enhancing the need for autonomous security mechanisms.
- Builder incentives must remain attractive and predictable to drive continuous ecosystem expansion without overreliance on inflationary incentives.
It’s time for Astar to take the next bold step.
Introducing Astar’s New Tokenomics Design
This proposal outlines a strategic evolution of Astar’s tokenomics to build resilience, independence, and sustainable growth for the years ahead.
1. Fixed Supply: A Stronger Foundation
- Total Supply: maximum supply at ~10.5 billion ASTR for 50% ideal staking ratio.
- No future minting: Inflationary emissions will be phased out over time.
2. Emission Structure: Dynamic Participation, Gradual Decay
Emissions will continue to adjust dynamically based on staking participation, targeting a 50% network staking rate — but with a new decay function applied.
- Emission Decay Formula: $ E(n) = E_0 \times (1 - r)^n $
Where:
-
R = 0.000008%, which is emission decay factor per block
-
E0= 136.67, which is current baseline emission at 50% ideal staking ratio
-
Emissions decrease exponentially at a rate of 0.000008% per block.
-
After 1 year: ASTR dynamic emission per block will be ~81% of today’s dynamic emission at 50% ideal staking ratio.
- $E(2,628,000) = E_0 \times (1 - 8 \times 10^{-8})^{2,628,000} \approx 0.810389$
- $E(2,628,000) = E_0 \times (1 - 8 \times 10^{-8})^{2,628,000} \approx 0.810389$
-
After 2 years: ASTR dynamic emission per block will be ~65% of today’s dynamic emission at 50% ideal staking ratio.
- $E(5,256,000) = E_0 \times (1 - 6 \times 10^{-8})^{5,256,000} \approx 0.656731$
- $E(5,256,000) = E_0 \times (1 - 6 \times 10^{-8})^{5,256,000} \approx 0.656731$
-
In the long term, total amount of ASTR emission after applying decay factor will converge to ~1.71B ASTR:
-
$C(n) = \frac{E_0}{r} (1 - e^{-rn})$
-
$\lim_{n \to \infty} C(n) = \frac{E_0}{r} = \frac{136.67}{6 \times 10^{-8}} \approx 1.708 \times 10^9\ \text{ASTR}$
-
Assuming deployment of new tokenomics happens in September 2026, with current ASTR supply of 8.4B and 39.37M emission from now to September 2026 considered, the maximum supply at 50% ideal staking ratio will be ~10.5B ASTR.
-
This smooth, exponential decay ensures rewards stay healthy for builders and validators, while naturally reducing emissions over time — balancing growth and sustainability.
3. dApp Staking Yield Projection
Builder rewards will continue, sourced from strategic reserves, ensuring stability during the transition.
Projected dApp staking APR (stakers):
- Currently dApp staking rewards for stakers is around ~17% APR with bonus reward considered when staking ratio is around 50%.
- Decreases gradually to ~13.8% APR in 1 year, to ~11% APR over 2 years.
This provides a predictable, attractive yield for builders — strengthening Astar’s ecosystem without over-dependence on inflation.
Protocol-Owned Liquidity (POL) by Astar Finance Committee (AFC)
Objective
- Secure Polkadot coretime slots without relying on crowdloans and adapt into Polkadot new tokenomics.
- Increase Astar’s financial independence and autonomous security.
Execution
- Managed by: Astar Finance Committee (AFC).
- Funding Sources:
- 20% of network fees redirected to AFC for POL operations.
- Expired/unclaimed staking rewards redirected.
- Strategic use of reserve ASTR if needed.
- Action Plan:
- Acquire DOT using treasury or fee revenues.
- Pair ASTR-DOT liquidity on selected platforms.
- Self-stake DOT to secure coretime slots.
- Reinvest POL yields back into ecosystem growth.
- Transparency:
- Monthly POL performance reports from AFC.
- Public dashboard for liquidity and coretime metrics.
Additional Measures
Network Fees and Burn Mechanism
- 50% of transaction fees burned permanently— reducing circulating supply over time.
- 30% of fees allocated to collators.
- 20% directed to ecosystem treasury for grants, POL funding and builder support.
Validator and Builder Incentives
- Validators (collators) continue receiving dynamic emissions.
- Builders are rewarded through sustainable dApp staking funded from reserves.

Together, we can future-proof Astar’s economy and ecosystem.
