@solworks/sujiko-sdk v0.2.0-alpha.8

Sujiko v1 Client Library

TypeScript client library for interacting with Sujiko v1.

Installation

Using npm:

npm install @solworks/sujiko-sdk

Using yarn:

yarn add @solworks/sujiko-sdk

Usage

1. Initialise SDK

import { SDK, Decimal, Side } from "@solworks/sujiko-sdk";
import * as anchor from "@coral-xyz/anchor";
// set anchor provider
const provider = anchor.AnchorProvider.env();
// lazy build sdk
let sdk = await SDK.build({
    connection: provider.connection,
    wallet: provider.wallet
    // devnet: true             // use devnet program id
});

2. Get markets

// fetch clearing house and markets list
let ch = await sdk.getClearingHouse();
let marketsList = await sdk.getMarketsList();
// pretty format clearing house
let clearingHouse = sdk.prettyFormat(
    ch, 
    marketsList,
    // true                     // excludes buffers
);
console.log(clearingHouse);

3. Create user if not exists

// update with mint of Sujiko Warrior owned by user
let mint = new PublicKey("...");

// check if user exists
let user = await sdk.getUser(provider.wallet.publicKey);
// create user if not exists
if (!user) {
    await sdk.initializeUser(
        provider.wallet.publicKey,
        mint
    );
}
// get user
user = await sdk.getUser(provider.wallet.publicKey);
// pretty format user
let prettyUser = sdk.prettyFormatUser({ user: user!, filtered: true });
console.log(prettyUser);

4. Deposit all collateral

// only usdc supported (collateralIndex = 0)
let collateralIndex = 0;

// get token account and balance
let ta = sdk.getTokenAccount(provider.wallet.publicKey, marketsList.collaterals[collateralIndex].mint);
let balance = await sdk.connection.getTokenAccountBalance(ta);

// deposit all
let toDeposit = Decimal.newScaled(balance.value.amount, marketsList.collaterals[collateralIndex].mintScale);
const sig = await sdk.deposit({
    owner: provider.wallet.publicKey,       // owner must = signer
    amount: toDeposit,                      // amount to deposit
    collateralIndex: collateralIndex,       // collateral index
    fromUserTokenAccount: ta,               // from user token account
});
console.log("sig", sig);

5. Place trade

// place trade in MADSLADS-PERP market for 1 contract long
// NOTE: order is executed asynchronously + takes >=5 slots before being executed
const market = marketsList.markets.find(m => m.name === "MADSLADS-PERP")!;
const size = 1;                             // 1 contract (i.e. 1 MADSLADS-PERP)
const sig = await sdk.createOrder({
    owner: provider.wallet.publicKey,       // owner must = signer
    marketIndex: market.index,              // alternatively use 0 for MADSLADS-PERP
    orderType: OrderType.Market,            // only Market or TriggerMarket supported currently (case sensitive)
    side: Side.Buy,                         // one of Buy or Sell (case sensitive)
    size: Decimal.fromSize(size)            // size of order, do not scale when using fromSize
});
console.log("sig", sig);
