+### 合约开发
+新建 cpp 和 hpp 文件，并导入 common.h 头文件，其中 common.h 中声明了 chain33 中的回调函数，是合约调用 chain33 系统方法的接口。   
+
+合约中的导出方法的所有参数都只能是数字类型，且必须有一个数字类型的返回值，其中非负值表示执行成功，负值表示执行失败。
+
+### 合约编译
+
+#### Emscripten 环境安装
+```bash
+git clone https://github.com/juj/emsdk.git
+cd emsdk
+./emsdk install latest
+./emsdk activate latest
+
+# 安装完之后需要配置临时环境变量，新建终端时需要重新执行以下命令
+
+# on Linux or Mac OS X
+source ./emsdk_env.sh
+
+# on Windows
+emsdk_env.bat
+```
+
+#### 使用 Emscripten 编译合约
+
+```bash
+em++ -o dice.wasm dice.cpp -s WASM=1 -O3 -s EXPORTED_FUNCTIONS="[_startgame, _deposit, _play, _draw, _stopgame]" -s ERROR_ON_UNDEFINED_SYMBOLS=0
+```
+
+- em++ 是 wasm 编译器，用来编译 c++ 代码，编译c代码可以用 emcc  
+- -o 指定输出合约文件名，格式为 .wasm   
+- dice.cpp 是源文件   
+- -s WASM=1 指定生成 wasm 文件   
+- -O3 优化等级，可以优化生成的 wasm 文件大小，可指定为 1～3   
+- -s EXPORTED_FUNCTIONS 指定导出方法列表，以逗号分隔，合约外部只可以调用导出方法，不能调用非导出方法，导出方法的函数名需要额外加一个 "_"
+- -s ERROR_ON_UNDEFINED_SYMBOLS=0 忽略未定义错误，因为 common.h 中声明的方法没有具体的 c/c++ 实现，而是在 chain33 中用 go 实现，因此需要忽略该错误，否则将编译失败
+
+参考文档：https://developer.mozilla.org/en-US/docs/WebAssembly
+
+#### 安装 wabt（the WebAssembly Binary Toolkit）
+
+```bash
+git clone --recursive https://github.com/WebAssembly/wabt
+cd wabt
+mkdir build
+cd build
+cmake ..
+cmake --build .
+```
+
+```bash
+# 通过 wasm 文件生成接口abi，abi中可以通过import关键字找到外部导入方法，以及export关键字找到编译时指定的导出方法。
+wabt/bin/wasm2wat dice.wasm
+```
+
+### 发布合约
+```bash
+./chain33-cli send wasm create -n 指定合约名 -p wasm合约路径 -k 用户私钥
+```
+
+### 调用合约
+```bash
+#其中参数为用逗号分隔的数字
+./chain33-cli send wasm call -n 发布合约时指定的合约 -m 调用合约方法名 -p 参数 -k 用户私钥  
+```
+
+### 转账及提款
+```bash
+#部分合约调用可能需要在合约中有余额，需要先转账到 wasm 合约
+./chain33-cli send coins send_exec -e wasm -a 数量 -k 用户私钥
+
+#提款
+./chain33-cli send coins withdraw -e wasm -a 数量 -k 用户私钥
+```
+### RPC接口调用
+```bash
+#构造调用合约的交易
