@acala-network/bodhi 中文文档教程
@acala-network/bodhi.js
bodhi.js SDK 实现了一个 web3 提供程序，以允许现有的以太坊 dApp 能够与 Acala EVM。
如果您使用的是 mandala tc6，那么您应该使用@acala-network/bodhi@0.2.x、@acala-network/api@0.7.1、@polkadot/api@4.2.1。
Getting Started
- Install dependencies
yarn
Documentation
大多数bodhi.js 的 api 与 ethers.js 兼容。 如果你不熟悉 ethers.js，你可以先看看它的文档
Provider
Provider 提供了一些 api用于与节点交互，是 ethers.js 抽象提供者。
Creating Instances
new Provider( apiOptions )
apiOptions 的参数与为 polkadot.js 创建 apiPromise 实例时相同
import { options } from "@acala-network/api";
import { Provider } from "@acala-network/bodhi";
import { WsProvider } from "@polkadot/api";
const evmprovider = new Provider(
options({
provider: new WsProvider("ws://localhost:9944")
})
);
Wallet
Wallet 类继承了 Signer，可以使用私钥对交易和消息进行签名。
Creating Instances
new Wallet( privateKey , provider? , keyringPair? )
“privateKey”是evm账户的私钥。 "provider" 是 Provider 的一个实例。 “keyringPair”是polkadot 的密钥对。 如果“keyringPair”为空，将生成一个密钥对 “私钥”。
import { Wallet } from "@acala-network/bodhi";
const wallet = new Wallet("0xaa397267eaee48b2262a973fdcab384a758f39a3ad8708025cfb675bb9effc20", provider)
Wallet.claimEvmAccounts()
使用“keyringpair”绑定一个由“privateKey”生成的evm账号。
wallet.claimEvmAccounts()
Examples
deploy a contract
import { deployContract } from "ethereum-waffle";
import ERC20Abi from "../build/ERC20Abi.json";
import { TestAccountSigningKey, Provider, Signer } from "@acala-network/bodhi";
import { WsProvider } from "@polkadot/api";
import { createTestPairs } from "@polkadot/keyring/testingPairs";
const provider = new Provider({
provider: new WsProvider("ws://127.0.0.1:9944"),
});
const testPairs = createTestPairs();
const signingKey = new TestAccountSigningKey(provider.api.registry);
signingKey.addKeyringPair(Object.values(testPairs));
const wallet = new Signer(provider, testPairs.alice.address, signingKey)
const tokenInstance = await deployContract(master, ERC20Abi, [1000]);
@acala-network/bodhi.js
bodhi.js SDK implements a web3 provider to allow existing Ethereum dApp to be able to interact with Acala EVM.
If you are using mandala tc6, then you should use @acala-network/bodhi@0.2.x, @acala-network/api@0.7.1, @polkadot/api@4.2.1.
Getting Started
- Install dependencies
yarn
Documentation
Most of the api of bodhi.js is compatible with ethers.js. If you are not familiar with ethers.js, you can start by looking at its documentation
Provider
The Provider provides some api for interacting with nodes and is an instance of ethers.js AbstractProvider.
Creating Instances
new Provider( apiOptions )
apiOptions has the same parameters as when creating an instance of apiPromise for polkadot.js
import { options } from "@acala-network/api";
import { Provider } from "@acala-network/bodhi";
import { WsProvider } from "@polkadot/api";
const evmprovider = new Provider(
options({
provider: new WsProvider("ws://localhost:9944")
})
);
Wallet
The Wallet class inherits Signer and can sign transactions and messages using a private key.
Creating Instances
new Wallet( privateKey , provider? , keyringPair? )
"privateKey" is the private key of evm's account. "provider" is an instance of Provider. "keyringPair" is a key pair for polkadot. If the "keyringPair" is empty, a key pair will be generated from the "privateKey".
import { Wallet } from "@acala-network/bodhi";
const wallet = new Wallet("0xaa397267eaee48b2262a973fdcab384a758f39a3ad8708025cfb675bb9effc20", provider)
Wallet.claimEvmAccounts()
Use "keyringpair" to bind an evm account generated by "privateKey".
wallet.claimEvmAccounts()
Examples
deploy a contract
import { deployContract } from "ethereum-waffle";
import ERC20Abi from "../build/ERC20Abi.json";
import { TestAccountSigningKey, Provider, Signer } from "@acala-network/bodhi";
import { WsProvider } from "@polkadot/api";
import { createTestPairs } from "@polkadot/keyring/testingPairs";
const provider = new Provider({
provider: new WsProvider("ws://127.0.0.1:9944"),
});
const testPairs = createTestPairs();
const signingKey = new TestAccountSigningKey(provider.api.registry);
signingKey.addKeyringPair(Object.values(testPairs));
const wallet = new Signer(provider, testPairs.alice.address, signingKey)
const tokenInstance = await deployContract(master, ERC20Abi, [1000]);
