Infrastructure

1. Alchemy is building Rundler

Rundler is designed from the ground up for performance and leverages years of experience at Alchemy running scalable web3 infra

Rundler is modular and loosely coupled, so you can:

• Scale components independently
• Run without RPC servers for the searcher use case
• Run without bundlers for the client use case
• Run without P2P for the private mempool use case

Rundler 是从头开始设计的，旨在提高性能，并利用 Alchemy 多年运行可扩展 web3 基础设施的经验。

Rundler 是模块化和松散耦合的，因此您可以：

• 独立扩展组件
• 在搜索器使用情况下无需 RPC 服务器运行
• 在客户端使用情况下无需打包程序运行
• 在私有内存池使用情况下无需 P2P 运行

2. Etherspot TransactionKit

Solution:

• Removes the complexity of blockchain development & reduces barriers to entry.
• Lets Web2 devs, without blockchain knowledge, build advanced Web3 apps.
• Gives frontend developers full creative control on how their components look
• Helpful code and error messages. If errors occur, TransactioKit will guide the developer through the steps required to fix them.

Etherspot TransactionKit 的解决方案：

• 简化了区块链开发的复杂性，降低了门槛。
• 允许没有区块链知识的 Web2 开发人员构建高级 Web3 应用程序。
• 让前端开发人员完全掌握他们的组件的外观。
• 提供有用的代码和错误信息。如果发生错误，TransactioKit 将引导开发人员完成必要的修复步骤。
