Rust 部署调用solidity智能合约

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以太坊部署调用solidity智能合约的代码。当然正常项目开发还是使用Truffle、Hardhat等框架部署调用测试方便，偶尔使用Java写的单元测试对一些常见的标准合约调用也比rust方便😂

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
3、这里使用BSC币安智能链测试网：https://bsc-testnet.public.blastapi.io

使用Cargo创建项目

cargo new deploy-contract

cd deploy-contract

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 = "deploy-contract"
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"
