Liquidswap

Liquidswap is Aptos’s first major AMM DEX, developed by Pontem Network, offering constant-product (xyk) and stable-swap pool types for Aptos Move assets — serving as the foundational liquidity layer for the Aptos ecosystem since mainnet launch in 2022 and maintaining deep liquidity for core trading pairs including APT, USDC, USDT, and major Aptos ecosystem tokens.

Overview

Liquidswap launched simultaneously with the Aptos mainnet in October 2022, making it the first significant DeFi protocol in the Aptos ecosystem. Pontem Network’s team had spent 2021–2022 building Move development tooling (Pontem IDE, Move Playground) and identified Aptos’s launch as the opportunity to bootstrap the critical DEX primitive. Being first on Aptos gave Liquidswap early liquidity network effects for key pairs, maintaining meaningful TVL even as competitors (Thalaswap, Cellana) arrived with more features. Liquidswap’s simplicity — traditional AMM with v2 Uniswap-style pools — was a feature during early ecosystem growth.

Pool Architecture

The protocol is built around the following components.

Uncorrelated Pools (xyk Constant Product)

Standard Uniswap V2-style pools:

  • Constant product formula: x × y = k
  • Suitable for volatile asset pairs (APT/USDC, APT/BTC, etc.)
  • Price determines along the invariant curve
  • LP earns 0.3% fee on all swaps

Correlated Pools (Stable Swap)

Curve-style pools for correlated assets:

  • Lower slippage near 1:1 price ratio
  • Suitable for stablecoin pairs (USDC/USDT) and LST pairs
  • StableSwap invariant with configurable amplification factor (A)
  • Lower fee rate (0.04%) reflecting reduced risk vs uncorrelated pools

Move Language Advantages

Liquidswap was among the first production deployments of Move language DeFi:

  • Move’s resource model — LP tokens are Move resources (owned by accounts, not approved via allowance)
  • Formal verification — Move’s type system enables stronger safety proofs of LP logic
  • Composability — Move functions can call Liquidswap pools atomically from other contracts
  • No reentrancy vulnerabilities (Move’s borrow checker prevents re-entrant calls)

Concentrated Liquidity Module

Liquidswap V2 introduced CLMM (concentrated liquidity):

  • LPs specify price range for liquidity (similar to Uniswap V3)
  • Higher capital efficiency within active range vs full-range xyk pools
  • Fee tiers: 0.01%, 0.05%, 0.3%, 1.0% (similar to Uniswap V3 fee tiers)
  • NFT-based position management (LP positions are Move resource objects)

Integration and Ecosystem Role

As Aptos’s first DEX, Liquidswap plays a foundational aggregation role:

  • Panora aggregator routes through Liquidswap pools alongside Thalaswap and other AMMs
  • Protocol-owned liquidity — several Aptos protocols bootstrapped their token liquidity on Liquidswap
  • Oracle source — Liquidswap pool prices used as secondary TWAP oracle data source for some Aptos protocols
