How Aster Chain staking works

The 30-second version

You lock ASTER for 26 weeks to 4 years. Longer locks earn more rewards. Two reward streams: a flat base APY from your chosen validator (~3.8%) plus a loyalty bonus from a shared 300,000 ASTER weekly pool, scaled by how long you locked and how much you trade on AsterDEX. Total APY ranges roughly 5% (26w / no boost) to ~16% (4y / 1.25× boost).

The five lock periods

Aster Chain supports exactly five lock durations. Each maps to a fixed time-weight used in the rewards formula:

* Loyalty APY at the no-boost tier (1.00×), as of epoch #6. Recompute live in the rewards calculator.

veASTER — your "voting power"

When you lock, the protocol mints you veASTER tokens (you don't see them in your wallet — they're a virtual accounting unit). veASTER is what determines your share of the loyalty reward pool.

veASTER = LockedAmount × (LockWeeks / 208)
Power   = veASTER × BoostTier

Example: lock 10,000 ASTER for 2 years (104 weeks).
→ veASTER = 10,000 × (104 / 208) = 5,000 veASTER.

The two reward streams

1. Base APY (from your validator)

You delegate to one validator. They produce blocks, the chain pays out a flat reward, you earn your stake's share minus the validator's commission. Currently every active validator runs at 0% commission and the network-average base APY hovers around 3.8%.

2. Loyalty APY (from the weekly pool)

Each week the protocol pays out 300,000 ASTER from a separate loyalty pool. Your share is proportional to your power against the network total:

YourReward = LoyaltyPool × (YourPower / TotalNetworkPower)
LoyaltyAPY = LoyaltyPool × 52 × TimeWeight × BoostTier
              ───────────────────────────────────────────
                         TotalNetworkPower

The denominator (Total Boosted veASTER) is currently around 169.5M. It's a settled snapshot from the previous epoch — that's how the AsterDEX UI computes the forward-looking APY shown on every lock period button.

Boost tiers (volume-based)

If you trade on AsterDEX, your loyalty rewards get multiplied. Volume is measured per epoch (1 week):

Early-exit penalty

You can break a lock early, but it costs you. The penalty is proportional to time remaining:

Penalty = max(2%, min(60%, WeeksRemaining / 208))

Halfway through a 4-year lock = 50% gone. Halfway through a 26-week lock = 6.25% gone. The penalty is a hard floor of 2% (so even unlocking 1 day early costs something) and a hard ceiling of 60% (so 4-year lockers can never lose more than 60% by early-exiting on day 1).

Worked example

You lock 10,000 ASTER for 2 years (104w), delegated to a validator earning 3.86% base APY, no trading boost (1.00×).

• veASTER: 10,000 × 0.50 = 5,000
• Base reward: 10,000 × 0.0386 / 52 = 7.42 ASTER/epoch
• Loyalty reward: 300,000 × (5,000 / 169,565,217) = 8.85 ASTER/epoch
• Total: ~16.3 ASTER/epoch = 847 ASTER/year = ~8.5% total APY

Plug your own numbers into the staking rewards calculator. It uses the live formula and matches the official AsterDEX UI to ±0.1pp.

Where to actually stake

AsterScan is a read-only explorer. To stake, go to asterdex.com/staking, connect your wallet, deposit ASTER, pick a validator + lock period, confirm.

Common gotchas

• Lock = lock. There is no "soft" unlock. If you change your mind in week 3 of a 4-year lock, you eat the ~58% penalty.
• Pick your validator carefully. Commission is currently 0% across the set, but a validator going offline costs you uptime credits. Use the validator profiles page to compare uptime + first-observed dates.
• Boost is per-epoch volume, not 30-day cumulative. If you cross 500K USDT in a single week you're Tier 1 that week. The next week you start over.
