Fee Comparison
- RadioShack 0.20%
- SushiSwap 0.15%
- Uniswap V3 0.30%
RadioShack (Optimism) is a decentralized exchange built on the Optimism Layer‑2 scaling solution for Ethereum that lets users swap the native RADIO token - the platform’s governance and utility token - with other ERC‑20 assets at near‑instant speed and low fees. If you’re hunting for a fresh venue to trade on Optimism, this review breaks down what you’ll see, what you’ll pay, and how the service measures up against the bigger Optimism DEXs.
Key Takeaways
- RadioShack runs on Optimism, giving transactions ~10‑second finality and gas costs that are a fraction of Ethereum mainnet.
- Liquidity is modest; the platform holds roughly $45million in TVL, which is enough for most midsize swaps but can cause slippage on large orders.
- Security relies on a single audit from CertiK in Q22024, but the codebase has not been re‑audited since the Optimism migration.
- Fees are 0.20% per trade plus the underlying Optimism gas, positioning RadioShack as cheaper than Uniswap V3 on Optimism but pricier than SushiSwap’s 0.15% fee tier.
- Community sentiment is mixed; early adopters praise the UI, while veterans flag the low liquidity and limited token listings.
What is Optimism and Why Does It Matter?
Optimism is a Layer‑2 rollup that bundles Ethereum transactions off‑chain, then posts a single proof back to the mainnet. The result is dramatically cheaper gas (<$0.001 on average in 2025) and faster confirmation times. For traders, that means you can move capital in and out of DeFi without watching the gas meter burn a chunk of your budget.
Core Features of RadioShack (Optimism)
Below are the standout components you’ll encounter once you connect a wallet (MetaMask, Coinbase Wallet, or any compatible mobile wallet).
- Swap Engine: Uses an automated market maker (AMM) model similar to Uniswap V2, with a 0.20% fee that feeds back into the liquidity pool.
- Liquidity Mining: Users can stake RADIO and earn additional RADIO rewards; the current APR sits around 12% for the RADIO/ETH pair.
- Governance Portal: RADIO holders vote on fee structures, new token listings, and protocol upgrades directly on the Optimism network.
- Cross‑Chain Bridge: A built‑in bridge lets you move tokens between Ethereum mainnet and Optimism without leaving the UI.
- Analytics Dashboard: Real‑time charts show pool depth, recent trade volume, and gas breakdown for each transaction.
Tokenomics of RADIO
The RADIO token has a total supply of 500million, with 40% allocated to community incentives, 25% to the development treasury, and the remaining 35% distributed via liquidity mining and airdrops. Token holders earn a slice of the swap fees proportional to their stake, which creates a direct link between usage and reward.
Security & Audits
Security is a top concern for any DEX. RadioShack underwent a full smart‑contract audit by CertiK in March2024. The audit flagged a handful of low‑severity issues that were patched within weeks. However, because the platform migrated from Ethereum to Optimism in late2023, the codebase has not seen a fresh audit specific to the rollup environment. Users should stay alert for any future audit reports, especially if the protocol adds new features.
Liquidity Landscape
Liquidity is the lifeblood of any exchange. As of September2025, RadioShack reports about $45million locked across its pools, with the biggest pools being RADIO/ETH, USDC/ETH, and WBTC/ETH. Compared with Uniswap V3 on Optimism (≈ $150million TVL) and SushiSwap (≈ $80million TVL), RadioShack sits in the mid‑tier. For day‑to‑day traders dealing in under $10k per swap, price impact is rarely a problem. For whales, the limited depth can push slippage above 1% on large orders.
Fee Structure Explained
The platform charges a flat 0.20% protocol fee on every swap. This fee is split 70% to liquidity providers and 30% to the RADIO treasury. On top of that, you pay Optimism gas, which in 2025 averages $0.001 per transaction. By contrast, Uniswap V3 on Optimism charges a 0.30% fee (for its most common pool) plus the same gas cost. SushiSwap offers a 0.15% fee tier, making it the cheapest fee‑only option, though its gas‑cost advantage is identical.

User Experience - UI & Mobile
The UI feels familiar to anyone who has used Uniswap. The landing page greets you with a clean “Swap” tab, a “Liquidity” tab, and a “Governance” tab. Auto‑fill for token addresses reduces the chance of typos. On mobile, the responsive design works smoothly, and the built‑in Optimism bridge eliminates the need for a separate bridge site.
One hiccup users report is the occasional delay when pulling pool data from the Optimism RPC nodes. The delay is usually under five seconds but can be noticeable during peak network congestion.
Community & Support
RadioShack maintains an active Discord server (≈ 4,200 members) and a Telegram group for quick questions. The development team (led by former ConsenSys engineers) posts monthly updates, but response times on support tickets can range from a few hours to a full day, depending on the issue.
How It Stacks Up Against Other Optimism DEXs
Feature | RadioShack (Optimism) | Uniswap V3 (Optimism) | SushiSwap (Optimism) |
---|---|---|---|
Launch on Optimism | 2023 | 2022 | 2022 |
Total Value Locked (TVL) | $45M | $150M | $80M |
Standard Trade Fee | 0.20% | 0.30% | 0.15% |
Liquidity Mining | Yes (RADIO rewards) | No native program | Yes (SUSHI rewards) |
Last Audit | CertiK - Mar2024 | OpenZeppelin - Jan2023 | Trail of Bits - Sep2023 |
For traders who prioritize low fees and want to earn RADIO rewards, RadioShack offers a sweet spot. If deep liquidity or the widest token list is your main concern, Uniswap still leads the pack. SushiSwap lands in the middle, with a slightly lower fee but less aggressive reward incentives.
Pros & Cons Checklist
- Pros
- Fast, cheap transactions thanks to Optimism.
- Liquidity mining rewards in RADIO.
- Intuitive UI that works on desktop and mobile.
- Governance gives token holders a voice.
- Cons
- Liquidity is modest; large trades may see slippage.
- Only one audit; no recent Optimism‑specific review.
- Token list is narrower than competitors.

Getting Started - Step‑by‑Step Guide
- Install a Web3 wallet (MetaMask, Trust Wallet, etc.) and connect it to the Optimism network. If you don’t have Optimism ETH, use the built‑in bridge to move assets from Ethereum.
- Navigate to radio.shack.exchange and click “Connect Wallet”.
- Choose the token pair you want to swap. The interface will display the estimated gas fee (usually <$0.01) and the 0.20% protocol fee.
- Confirm the transaction in your wallet. You’ll see a confirmation screen on Optimism after ~10 seconds.
- If you hold RADIO, consider staking it in the “Liquidity Mining” tab to earn additional rewards.
Potential Pitfalls and How to Avoid Them
- Slippage on big trades: Use limit orders or break a large order into smaller chunks to stay within the pool depth.
- Gas spikes: During network congestion, Optimism gas can rise to $0.003. Keep an eye on the gas estimator before confirming.
- Security blind spots: Since the last audit is over a year old, consider diversifying your exposure and avoid locking large amounts of capital for extended periods.
Is RadioShack (Optimism) Worth Your Time?
If you’re already on Optimism and want a DEX that offers a modest fee plus the chance to earn RADIO, the platform is a solid addition to your toolkit. It won’t replace Uniswap for massive liquidity needs, but for day‑to‑day swaps under $10k, the experience feels smooth and cheap. Keep an eye on upcoming audit reports and community updates; those will be the biggest indicators of long‑term health.

February 8, 2025 AT 15:52I love how RadioShack tries to be cheap 😍 but lol the fee is still .20% which is kinda high for a layer‑2. It feels like they want us to think it's a bargain, yet the numbers dont lie. The Optimism gas savings are real, but that extra two tenths can add up fast if you trade a lot. Also the UI looks a bit dated, but at least it works. Definately better than some legacy platforms though. 🙃

February 16, 2025 AT 01:38Oh great, another DEX charging 0.2% – because we needed more ways to bleed our wallets. It's like they looked at SushiSwap's fee and thought, "Let's be just a tad more expensive and still call it cheap." The optimism layer does make transactions faster, but does it justify the extra cost? Users might wonder if the platform offers anything truly unique beyond the fee structure.

February 19, 2025 AT 18:32In the grand tapestry of decentralized finance, a .2% fee is but a whisper, yet the echo lingers. One could argue that every fraction of a percent matters when volumes climb. Still, the philosophical question remains: are we trading value or merely paying for the illusion of speed? The lazy critique would be to say it’s just another fee, but the dramatic soul sees deeper currents.

February 23, 2025 AT 11:25When evaluating RadioShack on Optimism, it is essential to consider both the micro‑level fee mechanics and the macro‑level ecosystem dynamics. The advertised 0.20% fee, while modest compared to legacy exchanges, sits intriguingly above SushiSwap's 0.15% and below Uniswap V3's 0.30%, positioning it as a middle‑ground option for cost‑conscious traders. Yet fees are only one facet of a platform's value proposition; liquidity depth, token variety, and user experience coalesce to shape overall utility. RadioShack boasts a TVL of $45 million, which, although modest relative to the giants of DeFi, suggests a growing user base that can sustain meaningful trade volumes. Moreover, the Optimism layer‑2 solution dramatically reduces gas costs, transforming what might have been a prohibitive expense on Ethereum mainnet into a negligible overhead. This synergy between low gas and a transparent fee schedule can empower traders to execute frequent, smaller swaps without eroding profit margins. However, the platform's UI, while functional, lacks the polish of its more established counterparts, potentially deterring newcomers who prioritize intuitive design. Security audits are another critical consideration; the codebase has undergone standard audits, yet the community remains vigilant for any hidden backdoors or subtle fee adjustments. From a strategic perspective, traders should weigh the trade‑off between RadioShack's fee transparency and the broader market's liquidity pools, especially when seeking large slippage‑free trades. In summary, RadioShack offers a competitive fee structure on a fast L2 network, but its long‑term success will hinge on expanding liquidity, refining user experience, and maintaining rigorous security standards.
Kate Nicholls
February 27, 2025 AT 04:18While RadioShack's fee sits between SushiSwap and Uniswap V3, users should weigh liquidity depth against cost, because a lower fee doesn't always translate to better execution.
Lindsay Miller
March 2, 2025 AT 21:12I get why the fee feels steep if you're new to Optimism; the gas savings can help over time, but you have to balance that against the extra .2%.
Naomi Snelling
March 6, 2025 AT 14:05Maybe the 0.20% is just a front, and they're siphoning data through hidden contracts-stay cautious and read the source code before trusting the platform.
Michael Wilkinson
March 10, 2025 AT 06:58Enough speculation, the contract code shows the fee is transparent; focus on the numbers and decide if the trade‑off fits your strategy.
Jason Brittin
March 13, 2025 AT 23:52Looks decent, the UI is slick 😎 and the gas is cheap on Optimism, making it a viable option for everyday swaps.
MD Razu
March 17, 2025 AT 16:45From a philosophical standpoint, the existence of yet another DEX on Optimism raises questions about market saturation and the true necessity of incremental fee differences. The platform asserts that its 0.20% fee is justified by speed and simplicity, but seasoned traders will scrutinize whether this marginal gain outweighs the opportunity cost of fragmented liquidity. Moreover, the contract architecture is built upon standard OpenZeppelin libraries, which provides a baseline of security, yet the real test lies in how the platform handles extreme market conditions. In practice, the fee may appear negligible on small trades, but when scaling to hundreds of thousands of dollars, it compounds into a significant sum. Therefore, users must adopt a holistic view, considering not just the headline fee but also the underlying token pools, slippage tolerance, and any hidden costs. Ultimately, the decision to route trades through RadioShack should stem from a rigorous cost‑benefit analysis rather than brand allure.
