How Does Aquarius Stellar Work?

DEX|Risk B-|6 mechanisms|4 interactions

Aquarius is the primary liquidity layer for the Stellar blockchain, operating since 2021. It incentivizes market makers and liquidity providers on Stellar's native DEX and its own AMM pools by distributing AQUA token rewards. The protocol is transitioning to Soroban smart contracts (Stellar's new smart contract platform) for fully decentralized AMM functionality with stable and volatile pools. AQUA holders govern how rewards are distributed across different liquidity pools through a voting system similar to Curve's gauge system. With 100 billion AQUA tokens and no additional inflation, the fixed supply aims to create long-term scarcity.

Core Mechanisms

4.1.1

Soroban-based AMM with stable and volatile pools, multihop swaps, and concentrated liquidity on Stellar DEX

Standard AMM design ported to Stellar via Soroban smart contracts. Stable pools use Curve-style invariant, volatile pools use constant product.

7.1.2

AQUA rewards distributed to LP providers based on community governance votes (gauge-like system with voting and bribing)

Curve-style gauge system where AQUA holders vote on reward distribution across pools. Bribery market creates governance extractable value dynamics.

5.1.1

AQUA token governance for voting on liquidity reward allocation across Stellar DEX and AMM pools

Standard token-weighted governance. 100B total supply with no inflation. Governance primarily controls reward direction.

2.2.4

Trading fees from AMM pools split between LPs and protocol, with additional AQUA emission rewards

Standard LP fee model with emission incentive overlay. Fee income alone may not sustain LP interest.

7.4.1

AQUA locking for boosted governance voting power and reward multipliers

Standard vote-lock mechanism for increased influence. Creates governance centralization risk among early/large lockers.

8.2.1

Native to Stellar blockchain, operating across Stellar Classic DEX and Soroban AMM pools

Single-chain protocol (Stellar only). Benefits from Stellar network effects but limited by Stellar ecosystem size.

How the Pieces Interact

Soroban smart contract migration↔Previously battle-tested simple architectureHigh

The transition from a JavaScript-based rewards engine to Soroban smart contracts introduces new attack vectors. Soroban is Stellar's relatively new smart contract platform with a smaller security auditor ecosystem than Ethereum/Solidity.

AQUA emission rewards↔LP mercenary capitalMedium

Heavy AQUA emission incentives attract LPs who immediately sell rewards, creating persistent sell pressure on the governance token. As AQUA price falls, more emissions are needed to maintain the same dollar-denominated APY, creating an inflationary spiral.

Gauge voting and bribing↔Governance concentrationMedium

Large AQUA holders can direct emission rewards to their preferred pools through voting and bribing, extracting governance value at the expense of smaller participants and protocol-level liquidity optimization.

Stellar ecosystem dependency↔DeFi adoption trajectoryMedium

Aquarius success is capped by Stellar DeFi adoption. If Stellar fails to attract meaningful DeFi activity, AQUA liquidity incentives subsidize a small market, making the token economics unsustainable.

What Could Go Wrong

  1. Aquarius is transitioning from a JavaScript-based rewards engine to Soroban smart contracts on Stellar. This migration introduces smart contract risk to a protocol that previously relied on simpler, more battle-tested infrastructure.
  2. The AQUA token serves dual roles as governance and liquidity rewards. Heavy emission-based incentives to attract LPs create sell pressure on AQUA, potentially undermining its governance value as stakers dump rewards.
  3. Stellar ecosystem concentration risk: Aquarius is heavily dependent on Stellar network adoption. If Stellar fails to grow its DeFi ecosystem, AQUA liquidity incentives subsidize a shrinking market.

Soroban Smart Contract Exploit During Migration

Moderate

Trigger: Critical vulnerability discovered in new Soroban AMM contracts during or shortly after migration from legacy system

  1. 1.Bug discovered in Soroban AMM or rewards distribution smart contracts — Attacker drains LP funds from affected pools or mints unauthorized rewards
  2. 2.Protocol pauses affected contracts to prevent further loss — LPs cannot withdraw funds during pause, creating uncertainty
  3. 3.Confidence in Soroban contract security drops among LPs — Mass withdrawal after pause is lifted, TVL drops 50%+
  4. 4.AQUA token price crashes as protocol viability is questioned — Remaining emission incentives worth less, creating a negative feedback loop for LP retention
