\});

**发送交易  transfer()**

Param

"from": "account\_name", //发件人

"to": "account\_name", //收件人

"quantity": "asset", //资产

"memo": "string"

可选参数(after Param)

options = \{

authorization: 'tokyohotcoin@active', //签名交易用到的权限

broadcast: true, //是否广播交易

sign: true //是否签名交易

Example

**1)****公链令牌****(****EOS****)****转账**

1.    方式1

eos.transfer('tokyohotcoin', 'jailebihaido', '1.0000 EOS', '', options)

1.  方式2

eos.transaction(

actions: \[

account: 'eosio.token',

name: 'transfer',

authorization: \[\{

actor: 'tokyohotcoin', //发件人

quantity: '7.0000 EOS',  //发送资产

memo: ''

// options -- example: \{broadcast: false\} 自定义options

)

1.  **普通合约****令牌****(****代币****)****转账**

//  'myaccount' 创建合约代币(令牌的账户)

const myaccount = eos.contract('tokyohotcoin')

// 发送合约令牌

//  'test12344444'账户的私钥:    \\

//生成助记词

var mnemonic = BIP39.generateMnemonic();

//根据助记词生成种子

var seed = BIP39.mnemonicToSeed(mnemonic).toString(‘hex’);

//根据种子生成私钥

Var privatekey = eos.ecc.seedPrivate(seed )
