An SDK for building applications on top of Raydium.

## Usage Guide

### Installation

```
$ yarn add @raydium-io/raydium-sdk
```

### Enable special logger

```javascript
import { setLoggerLevel } from "@raydium-io/raydium-sdk";

setLoggerLevel("Common.Api", "debug");
```

## Features

### Initialization

```
import { Raydium } from '@raydium-io/raydium-sdk'
const raydium = await Raydium.load({
  connection,
  owner, // key pair or publicKey
  signAllTransactions, // optional - provide sign functions provided by @solana/wallet-adapter-react
  tokenAccounts, // optional, if dapp handle it by self can provide to sdk
  tokenAccountRowInfos // optional, if dapp handle it by self can provide to sdk
})
```

#### how to transform token account data

```
import { parseTokenAccountResp } from '@raydium-io/raydium-sdk'

const solAccountResp = await connection.getAccountInfo(ownerPubKey);
const tokenAccountResp = await connection.getTokenAccountsByOwner(
  ownerPubKey,
  { programId: TOKEN_PROGRAM_ID },
);

const { tokenAccounts, tokenAccountRawInfos } = parseTokenAccountResp({
  solAccountResp,
  tokenAccountResp,
})
```

### Liquidity

```
import { Raydium, Token, Percent, TokenAmount } from '@raydium-io/raydium-sdk'
import BN from 'bn.js'

const raydium = await Raydium.load({
  connection,
  owner // please provide key pair, if want to handle tx by yourself, just provide publicKey
  signAllTransactions // optional - provide sign functions provided by @solana/wallet-adapter-react
})

// Raydium.load call raydium.liquidity.load() automatically, also can call raydium.liquidity.load() manually

// if need trading pair info, call await raydium.liquidity.loadPairs()

const { transaction, signers, execute } = raydium.liquidity.createPool({
  version: 4,
  baseMint: new PublicKey(),
  quoteMint: new PublicKey(),
  marketId: new PublicKey() // https://docs.projectserum.com/serum-ecosystem/build-on-serum/add-a-market-on-serum-serum-academy
})

const { transaction, signers, execute } = raydium.liquidity.initPool({
  version: 4,
  baseMint: new PublicKey(),
  quoteMint: new PublicKey(),
  marketId: new PublicKey(),
  baseAmount: raydium.mintToTokenAmount({ mint, amount: "10" }),
  quoteAmount: raydium.mintToTokenAmount({ mint, amount: "20" }),
})
const { transaction, signers, execute } = raydium.liquidity.addLiquidity({
  poolId: new PublicKey(pool),
  payer: new PublicKey(payer), // optional
  amountInA: raydium.mintToTokenAmount({ mint, amount: "20" }),
  amountInB: raydium.mintToTokenAmount({ mint, amount: "30" }),
  fixedSide: "a", // "a" or "b"
})
const { transaction, signers, execute } = raydium.liquidity.removeLiquidity({
  poolId: new PublicKey(pool),
  payer: new PublicKey(payer), // optional
  amountIn: raydium.mintToTokenAmount({ mint, amount: "20" }),
})

const txId = execute()
```

### Liquidity

```
import { Raydium, Token, Percent, TokenAmount } from '@raydium-io/raydium-sdk'
import BN from 'bn.js'

const raydium = await Raydium.load({
  connection,
  owner // please provide key pair, if want to handle tx by yourself, just provide publicKey
  signAllTransactions // optional - provide sign functions provided by @solana/wallet-adapter-react
})

await raydium.ammV3.load() // load all clmm pool data

```

### Farm

```
import { Raydium, Token, Percent, TokenAmount } from '@raydium-io/raydium-sdk'
import BN from 'bn.js'

const raydium = await Raydium.load({
  connection,
  owner // please provide key pair, if want to handle tx by yourself, just provide publicKey
  signAllTransactions // optional - provide sign functions provided by @solana/wallet-adapter-react
})

await raydium.farm.load() // default load farms data
await raydium.farm.loadHydratedFarmInfo // load farms data width apr and detail info

```

#### Farm methods

```
raydium.farm.create({
  poolId, // oneOf liquidity pool id in https://api.raydium.io/v2/sdk/liquidity/mainnet.json
  rewardInfos // reward info array
})
const { transaction, signers, execute } = raydium.farm.restartReward({ farmId, rewardInfos })
const { transaction, signers, execute } = raydium.farm.addNewRewardToken({ poolId, newRewardInfo })
const { transaction, signers, execute } = raydium.farm.deposit({ farmId, amount })
const { transaction, signers, execute } = raydium.farm.withdraw({ farmId, amount })
const { transaction, signers, execute } = raydium.farm.withdraw({ farmId, withdrawMint: new PublicKey(xxx) })
const txId = execute()
```

#### Reward info example

```
const startTime = new BN(new Date("2022-08-20 15:00").getTime() / 1000)
const endTime = new BN(new Date("2022-08-30 15:00").getTime() / 1000)
const rewardPerSecond = new BN(totalAmount / (endTime - startTime))

const rewardInfo = {
  poolId: "13uCPybNakXHGVd2DDVB7o2uwXuf9GqPFkvJMVgKy6UJ",
  rewardInfos:[{
    rewardOpenTime: startTime,
    rewardEndTime: endTime,
    rewardMint: new PublicKey("So11111111111111111111111111111111111111112"),
    rewardPerSecond: rewardPerSecond.
  }]
}
```

### Swap

#### direct swap with automatically routes

```
import { Raydium, Token, Percent, TokenAmount } from '@raydium-io/raydium-sdk'
import BN from 'bn.js'

const raydium = Raydium.load({
  connection,
  owner // please provide key pair, if want to handle tx by yourself, just provide publicKey
  signAllTransactions // optional - provide sign functions provided by @solana/wallet-adapter-react
})

const { transaction, signers, execute } = await raydium.trade.directSwap({
  inputMint: ${rayMint},
  outputMint: PublicKey.default, // PublicKey as sol mint
  amountIn: "1.2345",
  slippage: new Percent(5, 100),
  fixedSide: "in"
})

const txId = execute()
```

#### custom controlled route swap

```
const { availablePools, best, routedPools } = await raydium.trade.getAvailablePools({
  inputMint: ${rayMint},
  outputMint: "sol",
})

const inputToken = raydium.mintToToken("4k3Dyjzvzp8eMZWUXbBCjEvwSkkk59S5iCNLY3QrkX6Rdecimals")
// or use new Token({ mint: "4k3Dyjzvzp8eMZWUXbBCjEvwSkkk59S5iCNLY3QrkX6Rdecimals: 6, name: "Raydium", symbol: "RAY" })
const outToken = raydium.mintToToken(PublicKey.default)
// or use new Token({ mint: PublicKey.default }) <= sdk will generate wsol token automatically

const { amountOut, minAmountOut, routes, routeType } =
  await raydium.swap.getBestAmountOut({
  pools: routedPools, // optional, if not passed, will auto choose best route
  inputToken: inputToken,
  outputToken: outToken,
  amountIn: '1.2345', // or new BN("1,2345");
  slippage: new Percent(10, 100) // 10%
})

const { transaction, signers, execute } = await raydium.trade.swap({
  routes,
  routeType,
  amountIn: raydium.mintToTokenAmount({ mint: ${rayMint}), amount: "1.2345" }),
  amountOut: minAmountOut,
  fixedSide: "in"
})

const txId = execute()
```
