前言

最近在学习Polkadot底层的substrate框架及moonbeam兼容以太坊的智能合约平台,为了更好的学习熟练Rust的语法编程，整理个Rust以太坊转账的代码。

准备

1、使用自己的节点或者使用第三方的公共节点提供RPC地址
2、以太坊地址

使用Cargo创建项目

cargo new ethers-transfercd ethers-transfer

请自行选用文本编辑器打开 Cargo.toml 文件。需要安装ethers.rs库等。

[package]name = "ethers-transfer"version = "0.1.0"edition = "2021"# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html[dependencies]ethers = "1.0.2"ethers-solc = "1.0.2"tokio = { version = "1", features = ["full"] }serde_json = "1.0.89"serde = "1.0.149"

构建并运行 Cargo 项目

使用 cargo run 一步构建并运行项目。

cargo run

控制台输出内容
