If you ever make swaps via any DEX, this is for you. Some tips to maximize return in DEX swaps: 1️⃣ Use a DEX Aggregator. 1inch is very good, but using swap.defillama (aggregator of aggregators) is better 2️⃣ After identifying the best one via DefiLlama, compare directly with their front ends. Sometimes final values differ. 3️⃣ MEV: protect against it. There are different alternatives to do this: • Using Cowswap. • Using 1inch Fusion instead of a regular trade. • Using Flashbots Protect RPC (docs.flashbots.net/flashbots…) They all work in a similar way: your transaction is not broadcasted to the mempool directly, and thus it's protected against front-runs. Sometimes you find the best rate in a DEX that does not offer MEV protection (for example Paraswap or Odos) and Flashbots RPC protects you in those cases. It also allows you to save gas fees on failed transactions: if you set slippage too low (which you should in most cases) then if the transaction fails it does NOT get broadcasted if using Flashbots. Win-win-win. 4️⃣ Find where the best pools are, with the most liquidity. Get the token smart contract from CoinGecko and then paste it on @GeckoTerminal or @Dexscreener to see where the token is being LPed and trading in all of DeFi. There are some rare cases where this might help discover a pool in a protocol that's not yet integrated with the aggregators. Also, pay attention if the token was deployed in different chains - sometimes the token contracts are different, and they have fragmented liquidity amongst different chains. 5️⃣ Same DEX, different fees: a trade in Curve is usually expensive compared to a similar one in Uniswap. This is because of how Curve's smart contracts work. > If you trade on Curve via 1inch, it's cheaper (gas-wise). 6️⃣ Try Gashawk (gashawk.io) to save fees on Ethereum transactions that are not time-sensitive. Like Flashbots, it's basically another RPC you add to your wallet. After you confirm the transaction in your browser, it is not directly broadcasted to the chain, but placed on hold. They have a dashboard where you can monitor all pending transactions (and cancel/speed them up). The idea of having this setup is that GH automatically broadcasts the transaction on their own once gwei is cheaper, allowing you to save money on fees. How does it work? After you sign the transaction locally, the signed hash (valid and ready to be broadcasted) is stored on their servers. They only delay sending it to the chain until gwei is lower. Same as Flashbots, they don't access any keys or can tamper with the transaction. 7️⃣ Limit orders: modern DEX aggregators like Matcha, 1inch, and Cowswap let you place "limit orders" in DeFi. How do they work? Similar to GasHawk - you sign the transaction on their front end, and they only broadcast it when/if the price you set is met. If not, they expire. You can also cancel them manually. 8️⃣ Which of these doesn't have a token? 🪂 DEX Aggregator airdrops are the easiest to qualify. Remember 1inch and Cowswap? More trades+More volume=Bigger airdrop. There are a few ones that do not have a token yet: • Matcha (though they are affiliated to 0x Protocol which already has a token, and they explicitly said "no token") • Odos (supports multiple chains, like Polygon) • Bebop (backed by Wintermute) • DeFillama (although it's important to mention that there is no DefiLlama smart contract interaction here. If they wanted to take a snapshot, they couldn't do it since you interact directly with the other protocols. Something could change in the future) ⚡️
