Staking
Overview
Delegate $ASTER to Aster Chain validators and earn rewards.
When staking, users make two key choices:
Select a validator
Choose a lock period
These two choices determine how rewards are generated and distributed.
The basic staking flow can be summarized as:
Select a validator → Stake $ASTER → Choose a lock period → Earn epoch rewards
What is a Validator?
A validator is responsible for processing transactions and producing blocks on Aster Chain.
When users stake $ASTER, they delegate their tokens to a validator. Each validator contributes differently to the network, and this performance determines the validator's total rewards.
Once the rewards are received, they are shared proportionally among delegators after deducting the validator's commission.
This design ensures validators compete based on real network contribution rather than simply attracting large amounts of stake.
What is the Lock Period?
The lock period is the duration where the staked $ASTER cannot be withdrawn without penalty. It determines your Loyalty Rewards weight, and a longer lock period means greater reward weight.
The current maximum lock duration is 208 weeks (approximately 4 years).
Dual Reward Structure
Aster Chain staking distributes rewards through two distinct layers.
Reward Layer
Determined By
Weekly Reward Pool
Base APY
Validator transaction share and your delegation size
150,000 $ASTER
Loyalty Rewards
Lock duration and trading activity
300,000 $ASTER+ Fee Buyback rewards (variable)
Separating these two reward streams serves two goals:
Encouraging healthy competition between validators
Incentivizing long-term staking commitment
New as of June 17, 2026: Loyalty Rewards now include a variable component on top of the 300,000 $ASTER base. Each epoch, all $ASTER bought back from platform fees is added to the Loyalty Rewards pool and distributed to veASTER holders by lock weight. Permissionless Spot listing fees fund a further buyback into staking rewards on a separate schedule. See Protocol Fee Rewards below for details.
Protocol Fee Rewards
As part of Aster's tokenomics upgrade, 99% of daily platform fees are automatically used to buy back $ASTER via TWAP. All bought-back $ASTER is distributed to veASTER stakers — on top of the 300,000 $ASTER base Loyalty Rewards each epoch.
This means your staking rewards scale directly with Aster's trading activity.
How it works:
99% of daily platform fees flow into the buyback wallet (0xa0edBaBcb48034e368de286b49F9603C7AfA1b60)
Buybacks execute via TWAP across each day and settle on-chain
Each epoch, the total buyback amount is added to the Loyalty Rewards pool and distributed to veASTER holders by lock weight
For every $ASTER bought back, an equal amount is burned from reserve — burns execute bi-weekly and continue until total supply reaches 3,000,000,000
Spot Listing Fees:
Each permissionless Spot listing incurs a 50,000 USDT fee, which is also used to buy back $ASTER as additional staking rewards. Listing fees are collected weekly and enter the buyback the following week, with staking rewards from this portion taking effect two weeks after listing.
