# 接入 EOS 钱包
通过 PW Core,你可以非常简单地在 dApp 中实现 CKB 和 UDT(用户自定义代币 User Defined Token)的接收和转账。
用户无需安装新的加密货币钱包、无需创建新的 CKB 助记词,只需要打开已有的加密货币钱包,使用已经习惯的 ETH / EOS / Tron 钱包和地址,即可实现 CKB 的收发和转账。
# 快速接入
在你的 dApp 中,添加如下 js 代码:
import PWCore, {
PwCollector,
ChainID,
Address,
Amount,
AddressType,
EosProvider,
EosSigner
} from '@lay2/pw-core'
// set the network parameters of EOS node
const network = {
blockchain: 'eos',
chainId:
'aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906',
host: 'eospush.tokenpocket.pro',
port: 443,
protocol: 'https',
}
// connect to CKB testnet: https://testnet.ckb.dev
// connect to CKB mainnet: https://mainnet.ckb.dev
const pwcore = await new PWCore('https://testnet.ckb.dev').init(
new EosProvider(network), // a built-in Provider for EOS env.
new PwCollector('https://cellapitest.ckb.pw') // a custom Collector to retrive cells from cache server.
)
# 常用指令
# 获取登陆地址
获取用户当前登陆的 EOS 地址:
// get the login EOS address.
const eosAccount = PWCore.provider.address.addressString
# 获取对应CKB地址
根据用户当前登陆的 EOS 地址,获取对应的 CKB 地址:
// change the login EOS address to ckb address.
const ckbAddress = PWCore.provider.address.toCKBAddress()
# 获取CKB余额
获取当前地址的 CKB 余额:
// get the balance of current address.
const ckbBalance = await PWCore.defaultCollector.getBalance(PWCore.provider.address)
更加通用化的,我们可以获取任意地址的 CKB 余额:
// get balance of any CKB address.
const anyCkbAddress = new Address('Any CKB address', AddressType.ckb)
const ckbBalance = await PWCore.defaultCollector.getBalance(anyCkbAddress)
// get balance of any EOS address.
const anyEosAddress = new Address('Any EOS address', AddressType.eos, 'lockArgs of this EOS address')
const ckbBalance = await PWCore.defaultCollector.getBalance(anyEosAddress)
# 获取SUDT余额
获取当前地址的 CKB 余额:
const sudtBalance = await PWCore.defaultCollector.getSUDTBalance(new SUDT(SUDT_ISSURER_LOCKHASH), PWCore.provider.address);
