Claimable balances matter because they are how Aquarius holds locked AQUA: its documentation lists a claimable balance for the AQUA locker among the reserves an account pays. For what the token is for, see what is the AQUA token.

How to choose

• You already hold XLM in a Stellar wallet: swap on Aquarius directly, or in LOBSTR if you prefer a phone app and accept its fee.
• You want a specific price: place a limit order on the Stellar DEX through a wallet or interface that supports offers.
• You are starting from a bank account: buy XLM on any exchange you already use, withdraw it to your Stellar wallet, then swap on-chain. That usually beats buying AQUA on a thin exchange market.
• You want to use the AQUA straight away for staking or ICE: buy into the same wallet you will use for that, so you do not pay to move it twice.

Before you buy: wallet, XLM and the trustline

You need a Stellar wallet holding XLM, enough XLM to cover reserves, and a trustline to the real AQUA issuer. A new account must hold 1 XLM, each trustline adds 0.5 XLM, and fees start at 0.00001 XLM per operation. Budget about 1.5 XLM plus whatever you plan to swap.

Stellar's documentation puts the base reserve at 0.5 XLM: an account must hold two of them (1 XLM), and every trustline, offer or extra signer adds another. Aquarius's own guide repeats those numbers and adds the ones its features use, such as 1 XLM per voting or governance claimable balance and 0.5 XLM for the AQUA locker. Reserves are not spent; they stay locked while the entry exists.

The trustline is where scams happen. Stellar lets anyone issue an asset with any code, so search results in wallets can show several "AQUA" tokens. The genuine one is issued by GBNZILSTVQZ4R7IKQDGHYGY2QXL5QOFJYQMXPKWRRM5PAV7Y4M67AQUA, and its stellar.toml is published at aqua.network. If a wallet shows a different issuer, it is a different token. Wallet choice is covered in the best Stellar wallets.

Buying on the Aquarius AMM

Aquarius is where most AQUA trades. Its swap page routes your order through its own pools, up to four hops in one transaction, and lets you set slippage from 0.1% to 10%. You pay the pool's fee, which the pool creator chose from fixed tiers, plus whatever price impact the trade causes.

The steps are short: connect a wallet, pick XLM (or USDC) to sell and AQUA to buy, check the quote, and sign. The docs set default slippage at 1% and note that "tighter values suit stable pairs; wider values help swaps go through in volatile or thin markets." Volatile pools charge 0.1%, 0.3% or 1%; stable pools 0.01% to 1%. Part of each fee goes to the protocol, set on-chain.

Depth decides most of the cost. On 8 October the largest AQUA pool reported by CoinGecko traded about $434K in a day, and the XLM/AQUA pool about $175K. A swap of a few hundred dollars barely moves those pools; a five-figure order deserves a look at the quoted price impact, or splitting into pieces. How the pools work: the Aquarius AMM explained.

Buying on the Stellar DEX

The Stellar DEX is the order book built into the network. You can buy AQUA with a market order that crosses the book or post a limit order and wait. On 8 October the best bids and asks sat about 578–580 AQUA per XLM, with several million AQUA bid near the top.

The order book charges no trading fee of its own; you pay the network fee and the spread. A resting limit order reserves 0.5 XLM while it is open. For mechanics such as path payments, which let a single transaction swap through intermediate assets, see the Stellar DEX explained. The SDEX is also what many "swap" buttons use underneath.

Buying in the LOBSTR app

LOBSTR's swap screen compares two routes, a classic Stellar swap through the DEX and AMMs, and an Aquarius AMM swap, and picks the better rate. It charges its own fee on top: 0.5% for featured assets including XLM, 0.6% for curated ones, 0.8% for known ones and 1% for unknown ones.

LOBSTR's support centre adds two details worth knowing. Classic swaps can buy an asset without an existing trustline, but "for swaps made via Aquarius AMM, you must manually add a trustline for the asset you want to buy beforehand." And the default slippage stops a swap if the final amount moves more than 1% after submission. The app fee is the price of convenience; on a large order, swapping on Aquarius directly saves it. LOBSTR also lists fee reductions for AQUA and ICE holders through its loyalty tiers.

Buying on a centralised exchange

Only two exchange markets showed up in CoinGecko and Coinpaprika data on 8 October: DigiFinex's AQUA/USDT, with about $13K of daily volume, and XT's AQUA/USDC, with about $260. Both are thin compared with on-chain venues, and withdrawing to a Stellar wallet adds a fee and a delay.

If you use one, confirm that the exchange supports AQUA withdrawals on the Stellar network to your own address, add the trustline in your wallet first, and include any memo the exchange asks for. A withdrawal to an account without the trustline will fail or be returned. For most buyers, moving XLM to a wallet and swapping on-chain is cheaper and gives a better price.

What it costs: a worked example

For a $500 purchase from XLM the network fee is negligible, the reserve is refundable, and the meaningful costs are the pool fee and slippage on Aquarius, or the app fee plus routing costs in LOBSTR. Roughly: $0.50–$1.50 of pool fee on Aquarius, or about $2.50 of LOBSTR fee on top of routing.

Using the published tiers: a 0.1% pool costs $0.50 on $500, a 0.3% pool $1.50. LOBSTR's 0.5% fee for featured assets is $2.50, before the route's own pool or spread cost. A network fee of 0.00001 XLM per operation is a tiny fraction of a cent at an XLM price of about $0.19. The 0.5 XLM trustline reserve (about $0.10) comes back if you later remove the trustline. Fee basics: Stellar transaction fees.

After you buy: stake, lock or provide liquidity

AQUA does three jobs on Aquarius: it can be locked for ICE, the non-transferable voting and boost token; it can be paired in liquidity pools; and it can be staked through third-party protocols. Each choice trades flexibility for yield, and locking is the least reversible.

Locking is the native route. Aquarius's formula is ICE = AQUA locked × (1 + 9 × min(days until unlock / 1,095, 1)), so a three-year lock gives up to ten times the AQUA amount in ICE. ICE votes on which markets receive AQUA emissions and boosts your own liquidity rewards by up to 2.5×. The docs are explicit that "ICE cannot be sent, traded, or deposited anywhere", and the AQUA only becomes reclaimable when the lock expires. Voting mechanics: ICE voting and bribes.

Staking through a protocol is the liquid alternative. WhaleHub, the publisher of this article, takes AQUA, issues BLUB as a staking receipt whose market price floats, and has paid staking rewards in AQUA since 14 September 2026; the step-by-step is in how to stake AQUA. Providing liquidity earns fees and possibly AQUA rewards but adds impermanent loss.

How these routes fit together

The venues are not separate markets so much as layers over the same liquidity. LOBSTR routes into the Stellar DEX and Aquarius pools; aggregators such as Soroswap's can route into Aquarius too; arbitrage keeps the order book and the pools close in price. Centralised exchanges sit outside that loop and, for AQUA, are too thin to set the price.

The takeaway

Buy AQUA on-chain. Fund a Stellar wallet with XLM, check the issuer, add the trustline, and swap on Aquarius or the Stellar DEX; use LOBSTR if the app's convenience is worth its fee to you. Decide what the AQUA is for before you buy, because locking it for ICE is a commitment of up to three years.
