Ethereum Payment 二维码生成器：常见错误与修复方法

使用方法

1. 先检查输入编码——多余的字节顺序标记或非 UTF-8 粘贴会在工具运行之前就破坏结果。
2. 留意静默截断：如果输出长度是可疑的整数，说明有内容被切掉了。
3. 确认你改动的选项正是任务所需；残留的默认值是"结果看似合理却错误"的最常见原因。
4. 先用你能手工验证的最小输入重跑，再把真实数据加回去。

示例

EIP-681 ethereum: URI; the address must be 0x plus exactly 40 hex characters.

输入

0x742d35Cc6634C0532925a3b844Bc454e4438f44e
