# inDEX JavaScript SDK

## Getting Started

```sh
npm install @phala/index
```

```javascript
import {Client} from '@phala/index'
const client = new Client()
await client.isReady
```

### EVM Chain

```javascript
import {lookupAsset} from '@phala/index'
import {Wallet, ethers} from 'ethers'

const privateKey = '0x…'
const wallet = new Wallet(privateKey)
const recipient = '0x…'
const solution = [
  // JSON solution
]

const moonbeam = client.createEvmChain('Moonbeam')
const asset = lookupAsset('Moonbeam', 'WGLMR')
const amount = ethers.parseEther('1')
const simulateResults = await client.simulateSolution(solution, recipient)
const approvalTx = await moonbeam.getApproval(
  asset.location,
  wallet.address,
  amount
)
if (approvalTx) {
  await wallet.signTransaction(approvalTx)
}
const deposit = await moonbeam.getDeposit(
  asset.location,
  amount,
  recipient,
  solution
)
const tx = await wallet.sendTransaction(deposit.tx)
const task = await client.getTask(deposit.id)
```

### Substrate Chain

```javascript
import {lookupAsset} from '@phala/index'
import Keyring from '@polkadot/keyring'

const mnemonic = 'mnemonic'
const recipient = '0x…'
const keyring = new Keyring({type: 'sr25519'})
const pair = keyring.addFromUri(mnemonic)
const solution = [
  // JSON solution
]

const simulateResults = await client.simulateSolution(solution, recipient)
const phala = client.createPhalaChain('Phala')
await phala.isReady // necessary for substrate chains
const deposit = await phala.getDeposit(
  lookupAsset('Phala', 'PHA').location,
  1_000_000_000_000n,
  recipient,
  solution
)
const txHash = await deposit.tx.signAndSend(pair)
const task = await client.getTask(deposit.id)
```

Description: This package contains implementation designed for integration with Solidity based Smart Contract with Phat Contracts.
Latest version: 0.0.4

# Phat Contract Solidity SDK

This package contains implementation designed for integration with Solidity based Smart Contract with Phat Contracts.

## Installation

We have tested with hardhat and Foundry. Truffle should be fine because it can import dependencies from the node_modules folder.

> [!WARNING]
> We recommend not using `forge install` if you are using Foundry, as it always uses the latest commit from the main branch. This can lead to version control issues and potential conflicts with dependencies. Instead, we suggest using `npm` or `yarn` as examples here.

### npm

```shell
npm install --save-dev @phala/solidity
```

### yarn

```shell
yarn add --dev @phala/solidity
```

### Setup remapping for Foundry

If you don't have the `remappings.txt`, you need to export remapping.

```shell
forge remappings > remappings.txt
```

And then added these two lines.

```txt
@openzeppelin/=node_modules/@openzeppelin/
@phala/solidity/=node_modules/@phala/solidity/
```


## Usage

```solidity
pragma solidity ^0.8.9;

import "@openzeppelin/contracts/access/Ownable.sol";
import "@phala/solidity/contracts/PhatRollupAnchor.sol";

contract OracleConsumerContract is PhatRollupAnchor, Ownable {
    event ResponseReceived(uint reqId, string reqData, uint256 value);
    event ErrorReceived(uint reqId, string reqData, uint256 errno);

    uint constant TYPE_RESPONSE = 0;
    uint constant TYPE_ERROR = 2;

    mapping(uint => string) requests;
    uint nextRequest = 1;

    constructor(address phatAttestor) {
        _grantRole(PhatRollupAnchor.ATTESTOR_ROLE, phatAttestor);
    }

    function setAttestor(address phatAttestor) public {
        _grantRole(PhatRollupAnchor.ATTESTOR_ROLE, phatAttestor);
    }

    function request(string calldata reqData) public {
        // assemble the request
        uint id = nextRequest;
        requests[id] = reqData;
        _pushMessage(abi.encode(id, reqData));
        nextRequest += 1;
    }

    function _onMessageReceived(bytes calldata action) internal override {
        // Optional to check length of action
        // require(action.length == 32 * 3, "cannot parse action");
        (uint respType, uint id, uint256 data) = abi.decode(
            action,
            (uint, uint, uint256)
        );
        if (respType == TYPE_RESPONSE) {
            emit ResponseReceived(id, requests[id], data);
            delete requests[id];
        } else if (respType == TYPE_ERROR) {
            emit ErrorReceived(id, requests[id], data);
            delete requests[id];
        }
    }
}
```
