实现Token项目

  1. 创建一个token项目

  2. token 项目依赖：

    [dependencies]
borsh = "1.5.7"
solana-program = "2.3.0"
spl-associated-token-account = { version = "7.0.0", features = [
    "no-entrypoint",
] }
spl-token = { version = "8.0.0", features = ["no-entrypoint"] }

[lib]
crate-type = ["cdylib", "lib"]

  3. 编写合约,具体代码见: https://github.com/SoniaChan33/token

  4. 起本地环境：➜ ~ solana-test-validator

  5. 打开log

    ➜  ~ solana logs

  6. 编译合约：

    ➜  token git:(master) ✗ cargo build-sbf

  7. 部署合约, 获取programID

    ➜  token git:(master) ✗ solana program deploy target/deploy/token.so
Program Id: 5DPHC1PjRftRHJLKD4WSSXt83h1AChJy2pHXUqGdKD9X

核心文件

具体实现文档见仓库readme文档：https://github.com/SoniaChan33/token?tab=readme-ov-file#spl-token合约项目实现文档

processor.rs：核心业务逻辑，处理指令

state.rs：定义账户的状态和扩展字段

instruction.rs：定义各种代币操作的指令

oerror.rs：定义了程序可能抛出的错误

olib.rs：程序入口点，汇总各个模块。

实现调用方Cli

  1. 创建项目

  2. 编写：具体代码见：https://github.com/SoniaChan33/solana-cli

  3. 测试结果：

    running 1 test
test test_fn ... ok

successes:

---- test_fn stdout ----
