feat(token): add Green Points (绿积分) ERC-20 token support
Add support for the dUSDT token "绿积分" (Green Points) on both Android and Electron applications: Android changes: - Add TokenType enum and GreenPointsToken config in Models.kt - Implement ERC-20 balance fetching and transfer encoding in TssRepository - Update TransactionUtils with ERC-20 transfer support - Add dual balance display (KAVA + 绿积分) in WalletsScreen - Add token type selector in TransferScreen Electron changes: - Add TokenType and GREEN_POINTS_TOKEN config in transaction.ts - Implement fetchGreenPointsBalance and ERC-20 transfer encoding - Update Home.tsx with dual balance display and token selector - Add token selector styles in Home.module.css Token contract: 0xA9F3A35dBa8699c8C681D8db03F0c1A8CEB9D7c3 (Kava mainnet) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

## 合约特性
|
||||
|
||||
### 固定供应量 - 无增发机制
|
||||
|
||||
该合约的核心特性是**完全禁止增发**：
|
||||
|
||||
1. **无 mint 函数**: 合约代码中不存在任何铸造新代币的函数
|
||||
2. **无 owner/admin 权限**: 合约没有特权角色，无人能修改供应量
|
||||
3. **供应量在构造函数中固定**: 所有代币在部署时一次性创建
|
||||
4. **totalSupply 是 constant**: 总供应量声明为常量，无法修改
|
||||
|
||||
### 支持的 ERC-20 标准函数
|
||||
|
||||
| 函数 | 描述 |
|
||||
|------|------|
|
||||
| `name()` | 返回代币名称 "Durian USDT" |
|
||||
| `symbol()` | 返回代币符号 "dUSDT" |
|
||||
| `decimals()` | 返回精度 6 |
|
||||
| `totalSupply()` | 返回总供应量 |
|
||||

## 在 MetaMask 中添加网络
|
||||
|
||||
### 主网
|
||||
|
||||
1. 打开 MetaMask
|
||||
2. 点击网络选择器 > 添加网络
|
||||
3. 填写以下信息:
|
||||
- 网络名称: `Kava EVM`
|
||||
- RPC URL: `https://evm.kava.io`
|
||||
- Chain ID: `2222`
|
||||
- 货币符号: `KAVA`
|
||||
- 区块浏览器: `https://kavascan.com`
|
||||
|
||||
### 测试网
|
||||
|
||||
1. 打开 MetaMask
|
||||
2. 点击网络选择器 > 添加网络
|
||||
3. 填写以下信息:
|
||||
- 网络名称: `Kava EVM Testnet`
|
||||
- RPC URL: `https://evm.testnet.kava.io`
|
||||
- Chain ID: `2221`
|
||||
- 货币符号: `KAVA`
|
||||
- 区块浏览器: `https://testnet.kavascan.com`
|
||||
|
||||
## Kava 双地址系统
|
||||
|
||||
Kava 网络支持两种地址格式:
|
||||
|
||||
| 类型 | 格式 | 示例 |
|
||||
|------|------|------|
|
||||
| Cosmos 地址 | kava1... | `kava1...abc` |
|
||||
| EVM 地址 | 0x... | `0x4F7E78d6B7C5FC502Ec7039848690f08c8970F1E` |
|
||||
|
||||
同一个私钥可以派生出两种地址，它们共享相同的余额。
|
||||
|
||||
## EVM 兼容性
|
||||
|
||||
Kava EVM 兼容以太坊 EVM，支持:
|
||||
|
||||
- Solidity 智能合约
|
||||
- ERC-20/ERC-721/ERC-1155 代币标准
|
||||
- Web3.js / ethers.js
|
||||
- MetaMask 等以太坊钱包
|
||||
|
||||
### 注意事项
|
||||
|
||||
- Kava EVM **不支持 PUSH0 操作码** (Shanghai 升级的特性)
|
||||
- 编译合约时需要使用 `evmVersion: "paris"` 或更早版本
|
||||
- 推荐使用 Solidity 0.8.19 或更早版本
|
||||
|
||||
## 常用合约地址
|
||||
|

|
||||
### Android/Kotlin
|
||||
|
||||
```kotlin
|
||||
// 使用 Web3j 或其他库
|
||||
val privateKey = "886ea4cffe76c386fecf3ff321ac9ae913737c46c17bc6ce2413752144668a2a"
|
||||
val credentials = Credentials.create(privateKey)
|
||||
println("Address: ${credentials.address}")
|
||||
// Output: 0x4F7E78d6B7C5FC502Ec7039848690f08c8970F1E
|
||||
```
|
||||
|
||||
## 地址派生
|
||||
|
||||
该地址是通过以下步骤从私钥派生的:
|
||||
|
||||
1. 私钥 (32 bytes): `886ea4cffe76c386fecf3ff321ac9ae913737c46c17bc6ce2413752144668a2a`
|
||||
2. 公钥 (65 bytes, uncompressed): `047e0b2f84204a2f859f51be78e09af3c504e9525f49d8ab1c537ab9c2a4deb28c3b16870449f50b9b79e959649a78144a5329958a95f6697534be0156b421588b`
|
||||
3. Keccak-256(公钥[1:65])
|
||||
4. 取后 20 bytes: `4f7e78d6b7c5fc502ec7039848690f08c8970f1e`
|
||||
5. 添加 0x 前缀: `0x4F7E78d6B7C5FC502Ec7039848690f08c8970F1E` (含校验和)
|
||||
|
||||
## 安全建议
|
||||
|
||||
1. **备份私钥**: 将私钥安全存储在离线环境中
|
||||
2. **不要分享**: 永远不要将私钥分享给任何人
|
||||
3. **不要提交**: 确保 .gitignore 包含此文件
|
||||
4. **硬件钱包**: 考虑将大额资产转移到硬件钱包
|
||||
5. **多签**: 对于生产环境，考虑使用多签钱包
