Uniswap v2 (Avalanche) Fee Calculator
How Fees Work on Uniswap v2 (Avalanche)
Uniswap v2 (Avalanche) offers four fee tiers that determine how much you pay for each trade. The fee is calculated as a percentage of your trade amount and goes to liquidity providers.
If you’ve ever wondered whether a decentralized exchange can feel as snappy as a centralized app while still keeping fees low, the answer lives on Avalanche’s C‑Chain. Uniswap v2 on Avalanche offers exactly that mix - sub‑second finality, sub‑0.3% fees for most pairs, and the familiar Uniswap interface you already trust.
Uniswap v2 (Avalanche) is the Avalanche deployment of the popular automated market maker (AMM) protocol originally built on Ethereum. It lets anyone swap ERC‑20‑compatible tokens without an order book, using smart contracts that calculate prices from the relative sizes of liquidity pools. The platform automatically detects your wallet, shows token balances, and executes swaps with a single click.
How the AMM Model Works on Avalanche
At the heart of Uniswap v2 is the constant‑product formula x·y = k. When you trade, the contract adjusts the ratio of two assets in a pool, keeping the product constant. The result is a price that moves smoothly with trade size, eliminating the need for matching orders.
Because Avalanche’s consensus is built on a Directed Acyclic Graph (DAG) and its Contract Chain (C‑Chain) runs an EVM, transaction finality averages 0.5seconds and gas costs are a fraction of Ethereum’s. That speed translates directly into less slippage for traders and cheaper fee payouts for liquidity providers.
Key Fees and What They Mean for You
Uniswap v2 lets liquidity providers set the fee tier when they create a pool. On Avalanche you’ll typically see three tiers:
- 0.01% for very stable pairs (e.g., AVAX/USDC‑stable versions).
- 0.05% for stablecoin‑to‑stablecoin swaps.
- 0.30% for most standard pairs.
- 1% for exotic or newly‑created pairs with low liquidity.
These fees are deducted from each trade and sent to the pool’s liquidity providers. Unlike centralized exchanges, the fee isn’t hidden - you can see the exact percentage before confirming the swap.
Setting Up - Connecting a Wallet
To start swapping, you need a Web3‑compatible wallet. The most common choice is MetaMask. After installing the extension, switch the network to “Avalanche C‑Chain” (or add it manually with RPC URLhttps://api.avax.network/ext/bc/C/rpc). When you land on the Uniswap v2 (Avalanche) site, the interface automatically reads your AVAX and token balances.
Once connected, you’ll see a clean two‑column layout: the token you’re selling on the left, the token you want to buy on the right. A slippage tolerance box lets you protect against rapid price swings - a handy feature when the market is volatile.
Liquidity Provision - Earning While You Hold
If you want to earn fees, you can become a liquidity provider (LP). Pick a pool, such as AVAX / USDC, and deposit equal USD values of both assets. The smart contract mints LP tokens that represent your share of the pool. Every time a swap occurs, a portion of the fee is sent to the pool, increasing the value of your LP tokens.
Uniswap v2 does not yet have the “concentrated liquidity” feature that v3 introduced, so your capital is spread across the entire price curve. This makes it simpler for new LPs but can lead to lower returns compared to v3’s range‑specific deposits.
Feature Spotlight: Flash Swaps and Range Orders
Even on v2, Uniswap offers advanced tricks. A Flash Swap lets you borrow assets from a pool, use them elsewhere (e.g., arbitrage), and repay within the same transaction. If the repayment fails, the whole swap reverts, meaning there’s no risk of losing funds.
Range orders, a workaround built on top of flash swaps, let you set a target price. The protocol automatically executes when the market hits that range, giving you a kind of limit order without a centralized order book.
How Uniswap v2 Stacks Up Against Other Avalanche DEXs
| Exchange | TVL (2025) | Typical Fee Tier | Token Count | Avg. Tx Speed |
|---|---|---|---|---|
| Uniswap v2 (Avalanche) | $1.2B | 0.30% | ≈85 | ≈0.5s |
| PancakeSwap (Avalanche) | $0.9B | 0.25% | ≈70 | ≈0.7s |
| Curve (Avalanche) | $0.8B | 0.04% | ≈30 (stablecoins) | ≈0.5s |
Uniswap still leads in total value locked and token variety, while PancakeSwap offers a slightly lower fee on many pairs. Curve dominates stablecoin swaps thanks to its ultra‑low 0.04% fee, but it doesn’t support the broader token range that traders often need.
User Experience - What Real Traders Say
First‑person reviews on sites like Milk Road describe the swap flow as “painless and intuitive.” Users love the instant wallet connection, the clear display of TVL, price charts, and the warning pop‑ups when a token has limited liquidity on Avalanche. A common complaint is the occasional lag in fiat‑price loading during high‑volume moments, which can make the USD value flash before it settles.
Another pain point: because Avalanche’s block time is so short, price impact can change in a few seconds. Traders who wait too long after hitting “Confirm” sometimes see a noticeably different output. The solution is to set a tighter slippage tolerance (e.g., 0.3%) and be ready to click quickly.
Security and Audits
Uniswap’s core contracts have been audited multiple times on Ethereum, and the same codebase was deployed to Avalanche with only network‑specific adjustments. The contracts are open‑source on GitHub, and the community can inspect every line. While no system is 100% hack‑proof, the track record of zero‑loss incidents on the Avalanche deployment (as of Oct2025) gives confidence.
Governance - The Role of UNI
The UNI token is Uniswap’s governance token. UNI holders vote on proposals that can affect fee structures, new feature rollouts, or even upgrades to the Avalanche version. As of this writing, UNI trades around $7.88, and the community treasury holds a modest share of AVAX to fund future Avalanche‑specific improvements.
Future Outlook - What’s Next for Uniswap on Avalanche?
Upcoming roadmap items include adding v3‑style concentrated liquidity to the Avalanche deployment, which would let LPs focus capital around tighter price ranges and improve fee earnings. There’s also a plan to integrate native Avalanche bridging solutions, reducing the need for third‑party bridges and cutting cross‑chain latency.
Technical analysis from October2025 shows a short‑term bearish bias for UNI, but the fundamental strength of Uniswap’s AMM model and Avalanche’s fast, low‑cost environment suggest the platform will stay a go‑to DEX for traders who value speed and a wide token selection.

Frequently Asked Questions
Is Uniswap v2 on Avalanche safe to use?
Yes. The same audited smart‑contract code that runs on Ethereum is deployed on Avalanche’s C‑Chain. Transactions settle in under a second, and the open‑source code lets anyone verify the logic.
How do fees on Uniswap v2 (Avalanche) compare to other DEXs?
Typical pools charge 0.30%, which is similar to Ethereum’s Uniswap v2 but lower than many centralized exchanges. PancakeSwap on Avalanche often lists 0.25%, while Curve’s stablecoin pools can be as low as 0.04%.
Can I trade directly from a hardware wallet?
Yes. Ledger and Trezor can be connected via MetaMask, which then interacts with Uniswap v2 (Avalanche) just like a software wallet.
What is a flash swap and should I use it?
A flash swap lets you borrow assets from a pool, use them in a single‑transaction operation (e.g., arbitrage), and repay instantly. It’s risk‑free if you can repay within the same transaction, but it requires smart‑contract knowledge.
Will Uniswap v2 on Avalanche support v3 features soon?
The roadmap indicates that concentrated liquidity (v3 style) will land on Avalanche by late 2025, giving LPs more control over capital efficiency.

May 31, 2025 AT 22:33Anyone who doubts that Avalanche can outpace Ethereum simply hasn't compared the block finality numbers. The sub‑second settlement on C‑Chain makes arbitrage bots breathe easier, and the fee structure-especially the 0.01% tier for stable pairs-shatters the myth that DEXes are always expensive. Moreover, the familiar Uniswap UI lowers the learning curve for anyone coming from the Ethereum version, so you don’t need to relearn everything. From a patriotic standpoint, it feels good to see US‑based developers leveraging a non‑EVM‑centric chain to push DeFi forward. In short, the speed and cost advantages are hard to ignore, and the ecosystem around AVAX is only getting richer.

June 3, 2025 AT 04:43Uniswap on Avalanche maintains the same trustless guarantees as on Ethereum, yet the lower gas price means you can afford to provide liquidity without eroding returns. The constant‑product formula stays unchanged, so the math remains transparent for anyone comfortable with basic AMM concepts.
Ikenna Okonkwo
June 5, 2025 AT 08:06Kudos for pointing out the fundamentals. The philosophy behind AMMs is to let markets self‑balance, which the Avalanche network accelerates due to its DAG‑based consensus. However, one should also watch for slippage spikes during high‑volume bursts, as the rapid block times can amplify price impact. Balancing fee tiers against expected volatility remains key for sustainable LP strategies.

June 7, 2025 AT 15:40To get started you need MetaMask and AVAX for gas. Add the Avalanche C‑Chain RPC manually if it’s not in your list. Verify the URL ends with ‘uniswap.org’ to avoid phishing sites. Connect your wallet and you’ll see your balances instantly. Set slippage tolerance around 0.3‑0.5 percent for stable swaps.

June 9, 2025 AT 23:13From a protocol perspective the flash swap mechanic leverages the atomicity guarantees of the EVM, allowing you to execute arbitrage loops in a single transaction. You essentially borrow liquidity, perform cross‑chain arbitrage via a bridge, and settle within the same block, which mitigates exposure. On Avalanche the reduced gas fee lowers the breakeven point for such strategies, making them economically viable at lower volumes.

June 12, 2025 AT 06:46Looks like another copy‑paste copy of the Ethereum UI with no real innovation.
Shikhar Shukla
June 14, 2025 AT 14:20While the presented features are commendable, it is incumbent upon potential users to conduct due diligence regarding contract audit reports and the provenance of the deployed bytecode on the Avalanche C‑Chain. Furthermore, the comparative analysis with competing DEXs should incorporate liquidity depth metrics beyond TVL to assess slippage resilience under stress conditions.

June 16, 2025 AT 21:53The sheer speed of transactions on Avalanche is a game‑changer for DeFi enthusiasts looking to execute time‑sensitive strategies. When you connect your wallet and fire off a swap, the confirmation usually lands within half a second, which is practically instantaneous compared to Ethereum's congested blocks. This low latency not only enhances user experience but also reduces implicit slippage that can erode profit margins in fast markets. Moreover, the fee structure on Uniswap v2 Avalanche is tiered to accommodate both stablecoin pairs and more volatile assets, offering a 0.01 % rate for ultra‑stable pairs. Such granular fee options empower liquidity providers to fine‑tune their exposure and maximize yield across different market conditions. From a liquidity provision standpoint, the absence of concentrated liquidity in v2 simplifies entry for newcomers, eliminating the need to calculate optimal price ranges. While this simplicity may result in modest returns relative to v3, it provides a safer sandbox for novices to learn the ropes without over‑allocating capital. The flash swap feature adds another layer of sophistication, enabling arbitrageurs to borrow assets and settle within the same transaction without collateral. On Avalanche, the reduced gas costs make these micro‑arbitrage loops financially viable even at lower trade volumes. Additionally, the protocol’s open‑source nature invites community audits, fostering transparency and trust in the underlying smart contracts. Security‑wise, the track record of zero‑loss incidents on the Avalanche deployment as of October 2025 speaks volumes about the robustness of the codebase. Governance through the UNI token also ensures that stakeholders can propose fee adjustments or feature rollouts, keeping the platform adaptable. Looking ahead, the upcoming integration of v3‑style concentrated liquidity on Avalanche promises to bridge the gap between ease of use and higher capital efficiency. Coupled with native bridge solutions, future updates aim to cut cross‑chain latency further, solidifying Uniswap’s position as a top DEX on the network. In summary, the combination of rapid finality, low fees, and a familiar interface makes Uniswap v2 on Avalanche a compelling choice for both traders and liquidity providers alike.
