Env requirement | 环境要求

• node installed | 安装了 node
• npm installed | 安装了 npm
• Able to connect fully synced khala node port 9944 | 能连接到已同步完成的 khala 节点端口 9944

---

Test connection of khala node | 节点连接测试方法

Linux system, curl & jq installed | Linux 系统，且需要已经安装 curl 和 jq

If node is in another machine, change localhost to the IP of the node | 如果节点不在本地，将 localhost 改成对应节点所在 IP

curl -sH "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "system_syncState", "params":[]}' http://localhost:9933 | jq '.result'

Usage | 使用方法

• First run | 初次安装依赖

npm i

• Change info in userInfo.json | 更改 userInfo.json 中的相应信息

{
  "mnemonic": "xxxx xxxx xxxx",
  "endpoint": "ws://localhost:9944"
}

• Fill in extrinsics in phala-api.js | 在 phala-api.js 中填写需要进行的交易操作

e.g. send 1 PHA to me | 举例：发送给作者 1 PHA

var txs=[
  api.tx.balances.transferKeepAlive("45BsgW5wSLE38P2AeogXRp67wge9pvP1sdm2ZgSWkLEPTBgX",1000000000000)
];

All operations that need to fill in the amount of PHA need to be multiplied by 1000000000000 (12 zeros)

所有需要填写 PHA 币量的操作都需要乘以 1000000000000（12 个 0）

• 1.23456789 PHA will be as 1234567890000 | 1.23456789 PHA 写作 1234567890000

---

Support multiple extrinsics | 支持多个不同请求同时发送

var txs=[
  api.tx.balances.transferKeepAlive("45BsgW5wSLE38P2AeogXRp67wge9pvP1sdm2ZgSWkLEPTBgX",3000000000000),
  api.tx.balances.transferKeepAlive("4237uB7vhW2XPTVWK6ikTMRHVGWTdXZ6ze5VJ9YVfMvnRoHg",2000000000000),
  api.tx.balances.transferKeepAlive("46C9Bmo9RUJXPd6rv4T3Phx9HEAU7tNbQkbStbrShspHoGq3",1000000000000)
];

• Run with node | 运行

node phala-api.js --send

Without --send option will not send on chain, will just retrun the hex of the extrinisics, which can be decoded in polkadot.js.org/apps

不含 --send 参数运行时只会返回十六进制编码而不会上链，可以在 polkadot.js.org/apps 进行解码

---

Extrinsics list | 可用交易列表

https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fkhala-api.phala.network%2Fws#/extrinsics

I might write a list of all available transactions and their usage later. | 之后可能会写所有可用交易及其用法的列表
