With the rapid development of blockchain technology, especially the widespread application of EVM-compatible chains, the decentralized finance (DeFi) ecosystem is flourishing. However, accompanying this are a series of challenges, one of which is the unfair competition brought by MEV (maximum extractable value) bots during token launches. Traditional token launch processes are often exposed to the risk of 'front-running', while bundled transactions as an innovative solution are bringing new fairness and efficiency guarantees to project teams and investors on EVM chains. This article will focus on the BNB Smart Chain (BSC) to explore the mechanism of bundled transactions and their implementation on the Slerf.tools platform, while also introducing their expansion applications on BSC, Ethereum, and Base chains.

Pain points of traditional token launches

In traditional token launch models, project developers typically follow these steps: first adding liquidity on decentralized exchanges (DEX) like PancakeSwap, and then users buy new tokens through trading. However, this process has significant vulnerabilities. Since blockchain transactions are temporarily stored in the memory pool (mempool) before being submitted to the chain, MEV bots can listen to the mempool and preemptively submit buy transactions the moment liquidity addition transactions are confirmed. This 'front-running' behavior allows bots to buy tokens at very low prices and then rapidly sell for profit when the price rises due to market enthusiasm.

For project teams, this situation can lead to early manipulation of token prices, harming the fairness of the launch; for ordinary investors, the slippage caused by front-running and high transaction costs reduce the return on participation. This opaque and unfair phenomenon is particularly prominent on high-throughput, low-cost chains (such as BSC), where the fast transaction speed and low costs attract a large number of MEV bot activities.

The innovative mechanism of bundled transactions

Bundled transactions fundamentally solve the aforementioned problems by integrating multiple operations into a single atomic transaction submitted to the blockchain. Taking BSC as an example, the bundled transaction feature provided by Slerf.tools binds the two operations of 'creating liquidity' and 'buying tokens' together as a single transaction on-chain. This design has the following key advantages:

  1. Atomicity ensures fairness
    Since bundled transactions are atomic, they either succeed or fail entirely, preventing MEV bots from inserting their trades between liquidity additions and purchases. This mechanism effectively eliminates front-running phenomena, ensuring that the interests of project teams and early investors are protected.

  2. Reducing slippage and costs
    In traditional models, the brief time window after liquidity addition often accompanies severe price fluctuations, leading to high slippage for buyers. Bundled transactions complete liquidity creation and purchases simultaneously, compressing the price fluctuation window to almost zero, allowing investors to purchase tokens at preset initial prices and significantly reduce trading costs.

  3. Improving launch efficiency
    By simplifying multiple-step operations into a single submission, bundled transactions not only improve operational efficiency but also reduce uncertainties caused by network congestion or transaction failures. This is particularly important for high-performance chains like BSC, which can fully leverage their low fees and high throughput.

Slerf.tools' practice of bundled transactions

Slerf.tools, as a platform focused on blockchain tool development, has deeply integrated the bundled transaction feature into its services, starting from BSC and gradually expanding to other EVM-compatible chains. Taking the applications on BSC as an example, Slerf.tools provides a user-friendly solution with specific functions including:

  • One-click creation of liquidity and purchase
    Users can simply visit https://bsc.slerf.tools/zh-cn/liquidity-create-and-buy-token/bnb to complete bundled transactions through simple operations. Developers can set liquidity parameters and execute purchases in one go, without worrying about being targeted by MEV bots.

  • Support for multi-address simultaneous purchases
    Slerf.tools has further optimized the bundling process, supporting simultaneous purchases of tokens from over 100 addresses. This feature not only enhances the efficiency of token distribution but also increases the dispersion of early participants, helping to build a healthier community ecosystem.

  • Security and transparency
    The operations of bundled transactions are completed entirely on-chain, with all steps being public and transparent. Users can verify transaction details through blockchain explorers like BscScan, ensuring fund security and process reliability.

From BSC to multi-chain expansion

While BSC has become an ideal testing ground for bundled transactions due to its low costs and high performance, Slerf.tools has not stopped there. Currently, its bundling function has expanded to other EVM-compatible chains such as Ethereum and Base, demonstrating strong cross-chain adaptability:

  1. Ethereum: Optimization of the high-value ecosystem
    As the birthplace of DeFi, Ethereum has the most mature ecosystem, but its high Gas fees and network congestion issues make MEV bot activities more rampant. Slerf.tools' bundled transactions provide a safety net for token launches on Ethereum, and although the transaction costs are higher, the fairness and efficiency improvements still hold significant value.

  2. Base: Exploring the potential of emerging chains
    Base, as a Layer 2 solution supported by Coinbase, combines the advantages of low cost and high scalability. Slerf.tools deploys bundled transactions on this chain, further promoting its application in the emerging EVM ecosystem and providing developers with more options.

  3. Cross-chain consistency
    Slerf.tools ensures that its bundled transaction tools have consistent operational logic across different EVM chains, so users do not need to relearn the process for each chain. This uniformity lowers the usage threshold and promotes the wider adoption of bundled transactions.

Future outlook for bundled transactions

The emergence of bundled transactions is not only a technical countermeasure against MEV bots but also an important step towards fairness and efficiency in the blockchain ecosystem. With Slerf.tools continuously iterating its toolkit, we can foresee the following development trends:

  • Wider chain support
    In the future, Slerf.tools may expand bundled transactions to more EVM-compatible chains (such as Polygon, Arbitrum, etc.) and even explore adaptation solutions for non-EVM chains, further expanding its influence.

  • Diversified functionality
    In addition to creating liquidity and purchasing, bundled transactions may integrate more operations (such as token burning, permission management, etc.) to provide a one-stop launch tool for project teams.

  • Community-driven optimization
    By collecting user feedback, Slerf.tools is expected to launch more customized features to meet the needs of different projects and investors.

Conclusion

In the rapid development of EVM chains, bundled transactions, as an innovative mechanism, are reshaping the rules of token launches. Starting from BSC, Slerf.tools, through its powerful tool support, not only enhances the efficiency and security for project teams but also creates a fairer participation environment for investors. From BSC to Ethereum to Base, the cross-chain expansion of bundled transactions demonstrates its limitless potential.
