Trust Wallet显示BUSD交易失败但实际成功，Metamask正常求助

问题出在这几个地方 #

• 重复引入不同版本的Web3库，导致和Trust Wallet的Provider兼容出问题
• wallet_addEthereumChain的参数不全，Trust Wallet对链配置的必填字段要求比MetaMask严格
• 交易处理里多余的await tx打乱了Promise逻辑，可能误触发错误捕获
• 未指定交易的gas参数，Trust Wallet自动估算时容易出现异常

核心改动点 #

1. 移除重复Web3引入：只保留最新版Web3，版本冲突是钱包兼容问题的常见诱因
2. 补全链配置字段：Trust Wallet要求rpcUrls、nativeCurrency、blockExplorerUrls等必填项，缺失会触发未预期的错误
3. 统一用async/await处理异步逻辑：避免Promise嵌套导致的逻辑混乱，确保每个异步步骤的错误都能被精准捕获
4. 手动指定gas参数：ERC20转账固定设置200000 gas足够，用链上实时gas价格，避免自动估算异常
5. 细分错误提示：区分用户主动取消交易和真实交易失败的场景，不再出现交易成功却弹失败的乌龙
6. 页面加载后执行初始化：确保钱包Provider已完全就绪，避免提前执行导致的初始化失败
