ICE tokens
Lock AQUA to receive ICE — non-transferable tokens that carry voting power and boost liquidity rewards.
ICE is locked AQUA. Locking converts AQUA into non-transferable ICE tokens that carry liquidity-voting power, governance-voting power, and a reward boost for liquidity providers. ICE cannot be sent, traded, or deposited anywhere.
How much ICE you get
The amount of ICE depends on how long you lock. The lock multiplier grows linearly with the time until unlock and caps at 10x at 1,095 days (3 years):
3 years or more
10x
100,000 ICE
2 years
7x
70,000 ICE
1 year
4x
40,000 ICE
6 months
2.5x
25,000 ICE
The lock multiplier is not the reward boost: locking determines how much ICE you hold, and the up-to-x2.5 reward boost is what that ICE earns you as a liquidity provider.
How ICE melts
Your ICE balance is not fixed. The protocol recomputes the expected amount daily from the formula above, and as the unlock date approaches, days until unlock shrinks — so ICE decays linearly toward 1x the locked AQUA at the unlock date. Excess ICE is reclaimed from your wallet and from your votes in batches throughout the day.
For example: 10,000 AQUA locked for 2 years starts at 70,000 ICE, melts to 40,000 ICE with one year remaining, and reaches 10,000 ICE on the unlock date — when the AQUA itself becomes reclaimable.
To maintain voting power, extend your lock or lock additional AQUA before melting erodes your balance.
Locking AQUA
Locking happens at aqua.network/locker and is executed entirely on the Stellar blockchain: the locker creates a claimable balance that only your wallet can reclaim once the selected lock period expires. Until then, the locked AQUA cannot be retrieved. For the interface walkthrough, see Locking AQUA into ICE.
The ICE token family
Locking mints three non-transferable tokens to your wallet:
ICE
Tracks how much AQUA you have locked and determines the distribution of upvoteICE and governICE. No direct operational use.
upvoteICE
Votes for markets at aqua.network/vote — eligibility thresholds are covered in Aquarius voting.
governICE
Votes on governance proposals.
A fourth token, downvoteICE, was used for downvoting markets. It was deprecated in June 2026 and can still appear in older wallets.
Delegation mints two more tokens — dICE and gdICE — covered in ICE delegation.
Why lock
Vote. Liquidity voting and governance both run on ICE — locking is how AQUA holders get a say. upvoteICE votes can be withdrawn at any time, and governICE is retrievable as soon as a proposal concludes.
Vote everywhere at once. The separate tokens let you participate in liquidity voting and governance simultaneously.
Earn more. Holding ICE boosts your AQUA rewards as a liquidity provider, up to x2.5.
