Why this matters: For large trades like $10,000, SithSwap's dual-mode AMM reduces slippage by 50%+ compared to traditional DEXs. You get better execution at near-zero cost.

What is SithSwap?

SithSwap is a decentralized exchange built on StarkNet, a Layer 2 scaling solution for Ethereum that uses zero-knowledge rollups to process transactions faster and cheaper. Unlike traditional exchanges, SithSwap doesn’t use order books. Instead, it uses an automated market maker (AMM) that lets users swap tokens directly from their wallets. It was launched in July 2023 and has quickly become the most used DEX on StarkNet, handling nearly 4 out of every 10 trades on the network.

SithSwap’s biggest advantage? It handles both stablecoins and volatile assets with unusually low slippage. If you’ve ever swapped USDC for USDT on Uniswap and ended up getting less than expected because prices moved during your trade, you know how annoying that is. SithSwap fixes that. For stablecoin pairs, slippage averages just 0.01% to 0.05%. For volatile tokens like STRK or STARK, it’s still under 0.3% - far better than the 0.5% to 0.8% you’d see on older DEXs.

How SithSwap Works: Dual-Mode AMM

SithSwap doesn’t use one trading formula. It uses two - and switches between them automatically. When you trade two stablecoins like USDC and USDT, it activates a Curve-style algorithm that keeps prices steady even with large trades. When you swap ETH for a new memecoin, it switches to a Uniswap V2-style constant product model (x*y=k) that handles price swings better.

This hybrid design is what sets SithSwap apart. Most DEXs have to choose: either low slippage for stablecoins or flexibility for volatile assets. SithSwap gives you both. It does this using StarkNet’s zk-Rollup tech, which batches thousands of transactions off-chain and posts one proof to Ethereum. That’s why fees are near zero - often just $0.002 per swap - and settlement happens in about 8 seconds.

Performance Compared to Competitors

On StarkNet, SithSwap leads the pack. As of September 2025, it handles 38.7% of all DEX volume on the network - more than JediSwap, mySwap, and 10K Swap combined. In head-to-head tests, SithSwap outperformed others in three key areas:

Slippage: 0.023% average on $10,000 USDC/USDT trades vs. 0.068% on Uniswap V2
Success rate: 98.7% of swaps under $50,000 complete without errors
Speed: 8.2 seconds median execution time vs. 14.7 seconds on JediSwap

But it’s not perfect. SithSwap only supports 87 token pairs as of late 2025. JediSwap offers over 140. If you’re trying to trade a newer StarkNet token that hasn’t been listed yet, you’ll need to use another exchange. That’s the trade-off for its precision.

Fees and Rewards

SithSwap charges a dynamic fee between 0.05% and 0.3%, depending on the asset pair. Stablecoin swaps cost 0.05%. Volatile trades cost 0.3%. Of that fee:

75% goes to liquidity providers
15% goes to the SithSwap treasury
10% goes to SITH token stakers

Compare that to JediSwap’s flat 0.3% fee or mySwap’s 0.25%. SithSwap rewards liquidity providers more fairly when trading low-volatility pairs. That’s why over $1.1 billion is locked in its pools - the highest on StarkNet.

The SITH Token and Governance

SITH is SithSwap’s native governance token with a fixed supply of 1 billion. You can’t buy it on major exchanges. Instead, you earn it by providing liquidity. The protocol distributes 45% of the total supply over four years as rewards.

But here’s the catch: to vote on proposals or boost your rewards, you need to lock your SITH into veSITH. This means you’re committing your tokens for at least 14 days. The longer you lock them, the more voting power and rewards you get. It’s similar to Curve’s veCRV model, but with less transparency. Some users complain the system is hard to understand without spending hours reading documentation.

Experts like Dr. Rebecca Shaw warn this model could backfire. If liquidity providers focus only on short-term rewards instead of long-term protocol growth, SithSwap might struggle to sustain its dominance. So far, it’s working - but it’s a risk.

Who Should Use SithSwap?

SithSwap is ideal for:

Stablecoin traders: If you’re constantly swapping USDC, USDT, DAI, or FRAX, this is the fastest, cheapest place to do it.
StarkNet users: If you’re already active on StarkNet, SithSwap integrates seamlessly with Argent X and Braavos wallets.
High-volume traders: With near-zero fees and 98.7% success rate, it’s perfect for executing dozens of trades a day.

It’s not ideal for:

Newcomers: The veSITH system and lack of educational content make it intimidating for beginners.
Niche token traders: If your token isn’t listed (and many aren’t), you’ll be stuck.
Those who want customer support: Response times average over two hours for non-premium users.

Security and Reliability

SithSwap inherits Ethereum’s security through StarkNet’s data availability layer. Every transaction is batched and verified on Ethereum mainnet every 10 minutes. That means even if StarkNet goes down, your funds are still safe.

Security audits from OpenZeppelin confirmed the core contracts are solid. But they also warned: the dual-mode system adds complexity. More code = more potential bugs. So far, no exploits have occurred, but liquidity providers should monitor pool health closely.

What’s Next for SithSwap?

The team is preparing for SithSwap v3.0, launching November 15, 2025. This update will add cross-chain swaps via Symbiosis Finance, letting users trade from Ethereum, Arbitrum, or Base directly into StarkNet assets - no bridges needed.

They’re also rolling out veSITH 2.0 in early 2026, which will reward liquidity providers who concentrate their funds in specific price ranges - a feature similar to Uniswap V3. And they’re exploring a protocol-owned liquidity model, which could reduce reliance on external providers and make the system more sustainable.

Analysts at Galaxy Digital and Delphi Digital expect SithSwap to hold 35-40% market share on StarkNet through 2026. But competition is heating up. Uniswap is planning its own StarkNet deployment, and if it brings its massive user base, SithSwap’s lead could shrink.

Final Verdict

SithSwap isn’t the easiest DEX to use, but it’s the most efficient on StarkNet. If you trade stablecoins often, need speed, and care about low fees, it’s the best choice available. Its hybrid AMM design solves real problems that older protocols ignore.

But if you’re new to crypto, trade obscure tokens, or want hand-holding support, look elsewhere. SithSwap is built for serious traders who value performance over simplicity.

For those willing to learn its system - especially veSITH and liquidity strategies - SithSwap delivers unmatched execution quality. It’s not just a swap tool. It’s a precision instrument for StarkNet’s growing DeFi economy.

Is SithSwap safe to use?

Yes, SithSwap is considered safe for experienced users. It runs on StarkNet, which batches and verifies all transactions on Ethereum mainnet, inheriting its security. Core contracts have been audited by OpenZeppelin with no critical vulnerabilities found. However, the complexity of its dual-mode system increases potential attack surfaces, so liquidity providers should monitor pools regularly and avoid large, unsupported token pairs.

How do I start using SithSwap?

First, install a StarkNet-compatible wallet like Argent X (version 2.4.1+) or Braavos (1.8.3+). Fund it with ETH or STRK. Then go to sithswap.com, connect your wallet, and select the tokens you want to swap. The interface is nearly identical to Uniswap, so if you’ve used a DEX before, you’ll feel right at home. First-time swaps take under 5 minutes.

What wallets work with SithSwap?

Only StarkNet wallets are supported. The two most reliable are Argent X and Braavos Wallet. You need version 2.4.1 or later for Argent X, and 1.8.3 or later for Braavos. These wallets support WebAssembly 2.0 and are optimized for StarkNet’s zk-Rollup tech. Avoid MetaMask or other Ethereum-only wallets - they won’t connect.

Does SithSwap have a mobile app?

No, SithSwap doesn’t have a dedicated mobile app. However, you can access it through the web browser on your phone using Argent X or Braavos Wallet’s built-in DEX browser. The interface is fully responsive and works well on iOS and Android. For best performance, use Chrome 115+, Firefox 110+, or Brave 1.55+.

How do I earn SITH tokens?

You earn SITH by providing liquidity to SithSwap pools. When you add ETH and a token (like USDC or STRK) to a liquidity pool, you receive LP tokens. These earn SITH rewards over time. The more liquidity you provide and the longer you lock your SITH into veSITH, the higher your rewards. Rewards are distributed weekly and are proportional to your share of the pool.

Why is SithSwap’s token selection so limited?

SithSwap prioritizes quality over quantity. Listing a new token requires a governance vote and liquidity assurance to ensure stable trading conditions. The team avoids low-liquidity or high-risk tokens that could cause slippage spikes or rug pulls. This keeps the platform reliable but means newer or obscure tokens aren’t available. If you need a token not listed, check JediSwap or 10K Swap.

What’s the minimum trade size on SithSwap?

There’s no official minimum trade size - you can swap as little as $1. However, liquidity pools require a minimum of $1,000 in total value to be active. If a pool falls below that, trading may be paused or become unreliable. For users, this means even small trades are safe, but you won’t find pools for very new or low-market-cap tokens.

Can I use SithSwap from the EU?

Yes, you can use SithSwap from the EU. However, the European Securities and Markets Authority (ESMA) has included StarkNet-based DEXs like SithSwap in its July 2025 guidance on decentralized exchange compliance. While no restrictions are in place yet, future regulations could impact access or require KYC for certain users. Always check local laws before trading.
