+### A deep dive into ERC-4337 smart contracts & how to spin up smart wallets for your app's users:深入研究 ERC-4337 智能合约以及如何为应用程序的用户启动智能钱包：
+
+By design, EOA wallets are limited in both features & flexibility. They can only perform 2 actions:
+从设计上来说，EOA 钱包的功能和灵活性都受到限制。他们只能执行 2 个操作：
+
+1. Transfer tokens to other EOAs
+2. Initiate transactions that trigger another smart contract transaction
+
+1. 将代币转移到其他EOA
+2. 发起交易触发另一笔智能合约交易
+
+These limitations present many challenges for users & developers:
+
+这些限制给用户和开发人员带来了许多挑战：
+
+### EOA disadvantages: EOA的缺点：
+
+1. Security: Dependent on one seed phrase. No spend limits, social recovery options, 2FA 
+2. Customization: Transactions from EOAs can't be customized/automated & must be manually signed
+3. Gas: Must own ETH to pay for gas at all times, can't use other tokens
+
+1. 安全性：依赖于一个助记词。无支出限制、社交恢复选项、2FA 
+2. 定制：来自 EOA 的交易无法定制/自动化，必须手动签名 
+3. Gas：必须始终拥有 ETH 来支付 Gas，不能使用其他代币
+
+### So why smart wallets? 那么为什么是智能钱包呢？ 
+
+As an individual, you may want to use a wallet with account recovery & multisig capability.
+
+作为个人，您可能希望使用具有帐户恢复和多重签名功能的钱包。 
+
+As a developer, you may want to issue wallets to your app's users with better UX: 'invisible wallets', gasless, batch txs... 
+
+作为开发人员，您可能希望以更好的用户体验向应用程序的用户发行钱包：“隐形钱包”、无gas、批量交易...... 
+
+But how do you put this into practice?
+
+但如何将其付诸实践呢？
