Understanding Transaction Fees on Decentralized Exchanges

After connecting a wallet to decentralized exchanges or other DApps and approving transactions, a user’s balance changes, which has nothing to do with the amount sent or staked somewhere in a DApp. Where did that money go to? An explanation of transaction fees is provided in this article. 

Understanding Transaction Fees on Decentralized Exchanges

Transactions in DeFi

DeFi transactions involve the exchange of tokens (swapping), staking of assets, minting, and deploying smart contracts, mostly executed through the calling of specific functions. Users only see a few of these as they perform their daily transactions since the aspect of the applications they interact with is the user interface. Fees are taken, anyway, and they are not just random.

Decentralized networks employ transaction fees to prevent spam by reducing the number of tokens owned by some percentage on every transaction. Some networks and DeFi projects use fees to incentivize specific activities that ensure the continuity of the network.

The most commonly incentivized activities are liquidity provision and block mining. Block mining or validation is a security mechanism that ensures that only valid transactions continue to exist on the blockchain.

Transaction Fees on Decentralized Exchange Platforms

Following the DeFi summer of 2020, and the popularity of Uniswap, many decentralized exchanges created on other blockchains followed a similar model. Users exchange one token for another and pay transaction fees. A portion of the fees goes to the liquidity providers in the automated pools whose funds ensure the continuity of the platform’s operation.

Aside from the fees charged by the exchange, there are also fees required by the native blockchain. Ethereum, for example, is the native blockchain and home to platforms like Uniswap and 1inch. Therefore, each platform transaction costs additional fees, which may be passed on to the users.

Transaction fees on a DApp are determined by the competition for the block space on the native blockchain, which is why the cost of transactions could increase significantly according to the level of demand at any given time. The only constraint is the gas limit which states the maximum amount that can be charged for the execution of a smart contract considering the computation being processed.

Increasing the gas price for a transaction makes it a higher priority transaction that will be included faster by miners on the blockchain. On some blockchains, users can decide to pay a higher fee for a transaction to incentivize miners to add it quickly to the blockchain.

DEX Fee Comparison on BNB Chain

Trading fees on the decentralized exchange on BNB Chain range from 0.2% to 0.5%. Some of these fees go to liquidity providers on the DeFi exchange platform, while some go to the platform’s treasury. The fee charged is the same for all transactions, and users mostly decide on which exchange to use based on their experience on the platform and other benefits.

High DEX crypto fees on an exchange can result from the developers’ decision, which is often justified in the project document or whitepaper. Some fees often go into programs and products that reward platform users. Since BNB Chain is already a haven for lovers of cheap fees and faster transaction time, millions of transactions are often executed on the blockchain at any given time.

Considering Rewards on DeFi Exchange Platforms Like Pandora

Pandora, an exchange on the BNB Chain charges a 0.3% fee for transactions on its platform. 0.03% of the charged fees go towards the operating fund, and 0.06% is sent to the jackpot. 0.21% then goes to the Pandora revenue pool or treasury. 

Pandora is important because the platform is built from the ground up to reward its users. Each transaction and activity on the exchange is recorded and awarded a point which can be converted into valuable rewards at some point during the user’s journey.

Regarding DEX fee comparisons, Pandora stands out for its transparent fees and commitment to rewarding its users with a portion of what is earned from its exchange activities. From DroidBot staking to yield farming, launchpad, and the first stable investment securities on the blockchain, Pandora, the platform’s reward structure is overwhelming. Every dime paid as fees on Pandora is more like an additional reward for the platform user.

Transaction fees are an important mechanism to guard and ensure the continuity of decentralized networks. While blockchains charge network fees for smart contracts and transaction execution, most DeFi exchange platforms also charge a fee unique to their platform.

These fees are used in the platform operation, while others, like Pandora, reward users directly from the fees paid as they use the exchange. BNB Chain is the most preferred blockchain for its speed and defaults low fees, which makes using DeFi exchange platforms even more user-friendly. Unlike other blockchains like Ethereum, where transaction fees can get pretty high, BNB Chain enables a seamless and cost-efficient DeFi experience for users.
