ethers
(我这里是间接引入JS
文件)<!-- 会导出一个全局的变量: ethers --> <script src="https://cdn.ethers.io/scripts/ethers-v4.min.js" charset="utf-8" type="text/javascript"> </script>
编写逻辑
// 1. 这里依照官网提供的代码引入 SDK import {MetaMaskSDK} from '@metamask/sdk' // 实例化 const MMSDK = new MetaMaskSDK(options); const ethereum = MMSDK.getProvider(); // 获取钱包地址, 没有装置钱包会提醒装置 MetaMask 钱包插件 const accounts = await ethereum.request({method: 'eth_requestAccounts'}) console.log(accounts, 'accounts') // 2. 获取签名和公钥 const provider = new window.ethers.providers.Web3Provider(ethereum) const signer = provider.getSigner() const signature = await signer.signMessage(`${Number(new Date())}`) console.log('签名后果:', signature) const publicKey = await signer.getAddress() console.log('公钥(以太坊地址):', publicKey)
连贯 UniSat
这里是我是应用 UniSat
钱包连贯
Docs
编写逻辑(UniSat
文档很不错,我就不做过多解释了)
import {getAddress, signTransaction, signMessage} from 'sats-connect'
// 判断是否装置了 UniSat 钱包
const iUniSat = () => {if (typeof window.unisat === 'undefined') {
// Element-ui Message 组件
Message({
type: 'error',
dangerouslyUseHTMLString: true,
duration: '20000',
message: `
Please install UniSat!
<a style="text-decoration: underline; font-weight: bold" target="_blank" href='https://chrome.google.com/webstore/detail/unisat-wallet/ppbibelpcjmhbdihakflkdcoccbgbkpo'>Download</a>
`
})
return false
}
return true
}
// 链接 UniSat 钱包
const connectUniSat = async () => {if (iUniSat()) {
try {const accounts = await window.unisat.requestAccounts()
console.log('链接胜利', accounts)
const r = await window.unisat.getAccounts()
console.log('钱包', r)
const publicKey = await window.unisat.getPublicKey()
console.log('公钥', publicKey)
const sign = await window.unisat.signMessage(`${Number(new Date())}`)
console.log('签名', sign)
} catch (err) {if (err.message) {Message.error(err.message)
}
console.log(err, 'err')
}
}
}
连贯 Xverse
钱包
Docs 连贯钱包局部能够参照文档,然而生成 PSBT
文档写的很烂,有些变量都不晓得哪里来的
筹备工作
-
装置 获取地址以及签名等 依赖包
yarn add sats-connect // or npm install sats-connect
-
装置生成
Psbt 依赖包
(也能够用npm
)yarn add @scure/base @scure/btc-signer
编写逻辑
try {let addresses = []
// 获取地址
await getAddress({
payload: {
// 这两都要
purposes: ['ordinals', 'payment'],
message: 'Address for receiving Ordinals',
network: {type: 'Testnet'}
},
onFinish: (response) => {
addresses = response.addresses
console.log('地址', addresses)
},
onCancel: () => {console.log('勾销')
}
})
} catch (err) {console.log(err)
// 没有装置钱包提醒去装置钱包
if (err.message === 'No Bitcoin Wallet installed') {
Message({
type: 'error',
dangerouslyUseHTMLString: true,
duration: '20000',
message: `
No Bitcoin Wallet installed!
<a style="text-decoration: underline; font-weight: bold" target="_blank" href='https://chrome.google.com/webstore/detail/xverse-wallet/idnnbdplmphpflfnlkomgpfbpcgelopg'>Download</a>
`
})
}
}
须要留神的是钱包中也要抉择为测试网
拿到地址数据后再获取地址代码前面增加生成签名代码
// await getAddress({
//...
// })
// 获取签名写在获取地址上面
await signTransaction({
payload: {
network: {
// 测试网 Testnet,主网 Mainnet。先用测试网测试
type: 'Testnet'
},
message: 'Sign Transaction',
// 调用生成 Psbt 函数
psbtBase64: createPsbt(addresses),
broadcast: false,
inputsToSign: [
{
// 这里为 payment address. payment address 在获取的值的时候拿到
address: addresses[1].address,
signingIndexes: [0]
}
]
},
onFinish: (response) => {
data.signatureBase64 = response.psbtBase64
console.log('签名', response)
},
onCancel: () => {console.log('sign cancel')
}
})
生成 Psbt
。先把 Docs 文档地址代码 copy
过去。而后更改相应变量值
残缺代码如下:
const createPsbt = (addresses) => {
// 文档上没有申明 tx 这里找了良久 tx 是什么
const tx = new btc.Transaction()
const bitcoinTestnet = {
bech32: 'tb',
pubKeyHash: 0x6f,
scriptHash: 0xc4,
wif: 0xef
}
const output = {
tx_hash: 'f39d37ec885de70c598648a2f80f103e1cdf34f7021ddfcb22216b7076169226',
block_height: 780179,
tx_input_n: -1,
tx_output_n: 1,
value: 300000,
ref_balance: 22681,
spent: false,
confirmations: 123,
confirmed: '2023-03-10T10:02:21Z',
double_spend: false
}
// addresses[1].publicKey 就是 payment publicKey,在获取地址时拿到
const publicKey = hex.decode(addresses[1].publicKey)
const p2wpkh = btc.p2wpkh(publicKey, bitcoinTestnet)
const p2sh = btc.p2sh(p2wpkh, bitcoinTestnet)
tx.addInput({
txid: output.tx_hash,
index: output.tx_output_n,
witnessUtxo: {
script: p2sh.script,
amount: BigInt(output.value)
},
redeemScript: p2sh.redeemScript
})
const recipient = addresses[0].address
const changeAddress = addresses[1].address
tx.addOutputAddress(recipient, BigInt(200000), bitcoinTestnet)
tx.addOutputAddress(changeAddress, BigInt(80000), bitcoinTestnet)
const psbt = tx.toPSBT(0)
const psbtB64 = base64.encode(psbt)
return psbtB64
}
如果要改成 Mainnet
状况下,须要将获取地址 getAddress,signTransaction
中的 network
对象下 type
属性的值都改成 Mainnet
。并且 bitcoinTestnet
变量也须要相应更改。
const bitcoinTestnet = {
bech32: 'bc',
pubKeyHash: 0x00,
scriptHash: 0x05,
wif: 0x80
}
以上就是 连贯以太坊、Xverse、UniSat 钱包并获取签名
全副代码了,心愿能够帮忙到有须要的小伙伴。
