How Does SaucerSwap V2 Work?
SaucerSwap V2 is the leading decentralized exchange on the Hedera network, offering concentrated liquidity trading (similar to Uniswap V3) with near-zero transaction fees thanks to Hedera's low-cost infrastructure. Users can swap tokens, provide concentrated liquidity to earn trading fees, stake SAUCE tokens for HBAR rewards, and farm additional SAUCE emissions. With over $5B in all-time volume and 15M+ trades, it is the dominant trading venue for the Hedera ecosystem. The protocol has been audited by Omniscia and Hacken, though the underlying Hedera network experienced a security incident in March 2023.

Core Mechanisms
4.1.2
Concentrated liquidity AMM ported from Uniswap V3 to Hedera Token Service
Uniswap V3 concentrated liquidity adapted for Hedera's unique smart contract model with Hedera Token Service integration.
2.1.2
Percentage-based swap fees from 0.05% to 0.30% depending on pair volatility
Standard tiered fee model matching Uniswap V3 fee tiers.
7.1.1
SAUCE token emissions to liquidity providers at ~127 SAUCE per minute
Standard liquidity mining with 60% reduction from original emission rate. Six-year emission runway from genesis.
3.1.1
Single-sided SAUCE staking with HBAR reward distribution
Pro-rata staking rewards funded by protocol fee revenue.
5.1.1
SAUCE token governance for protocol parameters and treasury
Standard token-weighted governance. 24% of supply allocated to core development team.
1.2.1
NovelTeam and development SAUCE allocation with vesting schedules
24% core development + 2% marketing + 2% operations vested to team. Community received 14% via PEC NFT distribution — novel NFT-gated airdrop approach.
How the Pieces Interact
The port from Solidity to Hedera's smart contract model requires non-trivial modifications. Subtle differences in how Hedera Token Service handles token operations could introduce edge cases not present in the original Uniswap V3.
Liquidity mining rewards attract capital to concentrated positions, but much of the incentivized liquidity may sit outside the active range, meaning the protocol pays for non-productive capital.
Staking rewards encourage holding SAUCE while emissions continuously dilute holders. If staking yield falls below emission dilution, rational actors sell rather than stake, creating downward price pressure.
The March 2023 Hedera network exploit demonstrated that network-level vulnerabilities can directly impact SaucerSwap liquidity pools, even without SaucerSwap-specific bugs.
What Could Go Wrong
- SaucerSwap V2 is a port of Uniswap V3 concentrated liquidity onto Hedera's non-EVM environment — adaptations to Hedera Token Service introduce implementation risk beyond the original Uniswap V3 code.
- The March 2023 Hedera network-level exploit affected DEX liquidity pools, demonstrating that Hedera's smart contract service has a shorter battle-testing history than Ethereum.
- SAUCE token has a $16M FDV with ongoing emissions of ~127 SAUCE/minute, creating significant dilution pressure against a protocol with $27M TVL.
Hedera Network-Level Exploit Repeat
ModerateTrigger: A new vulnerability in Hedera's smart contract service or token service is discovered and exploited
- 1.Attacker exploits Hedera network-level vulnerability — Liquidity pool tokens are stolen or manipulated across all DEXs on Hedera
- 2.SaucerSwap V2 pools are drained or disrupted — LPs suffer direct losses, token prices crash on Hedera ecosystem
- 3.Trust in Hedera DeFi ecosystem collapses — Capital flight from SaucerSwap and all Hedera DeFi protocols
